What was recalled
In March of 2018, the U.S. Consumer Product Safety Commission (CPSC) announced a significant safety recall involving a specific line of kitchen accessories manufactured by InSinkErator. The company, which is well-known for producing garbage disposals and related components, voluntarily issued this notice due to concerns over the reliability of its SinkTop™ Switch Accessory. This particular product was designed as a modern alternative to the traditional wall-mounted switch typically used to operate garbage disposals. Instead of requiring a button on the kitchen wall, the SinkTop switch mounts directly onto the sink or countertop surface, offering a sleeker, more integrated look for many homeowners.
The recall specifically targets the InSinkErator Single Outlet SinkTop Switches. It is important to distinguish that this issue does not affect every garbage disposal unit sold by the brand, nor does it impact disposals that are activated by standard wall switches. The problem is isolated strictly to these countertop-mounted units. Consumers who own these specific accessories need to check their hardware carefully, as the defect lies within the internal power module of the switch itself. InSinkErator has confirmed that water intrusion into this power module is the root cause of the safety concern, leading to the decision to pull these items from use entirely.
If you have one of the recalled units, you can identify it by looking at the back of the power module, which is usually located beneath your sink. The InSinkErator brand name will be clearly printed on the front of the power module, but the critical information for verification is found on the back. You are looking for one of the following four model numbers: 76703, STS-SOSN, 78251, or 74300. These switches were marketed as premium accessories and came with a button and bezel finish in one of three colors: chrome, white, or satin nickel. While the exact total number of units sold globally is not specified in the initial recall summary, the company has documented 40 reports of incidents related to this product.
These recalled switches were sold as accessories for garbage disposals, meaning they are often installed by homeowners during renovations or when upgrading an existing disposal system. Because they mount directly to the sink or counter, they can be easy to overlook in terms of maintenance or recall checks. However, given the potential risks involved, verifying your model number is a crucial first step in ensuring your kitchen remains safe. If you recognize one of these model numbers on your device, it is no longer considered safe for continued use without immediate remediation from the manufacturer.
The hazard, explained
To understand why this specific recall matters, it helps to look at the mechanics of how a garbage disposal switch works and where that particular design can go wrong. The InSinkErator SinkTop Switch is an air-activated device. Instead of a traditional electrical wire running directly from a wall switch to your disposal unit under the sink, this system uses flexible tubing to transmit air pressure. When you press the button on your countertop or sink deck, you are essentially blowing air through that tube to trigger a mechanism inside the power module, which then turns on the disposal. This design is popular because it allows for easy installation and avoids running electrical wires through potentially tricky cabinetry spaces.
The core issue identified by the Consumer Product Safety Commission (CPSC) involves the interaction between this air-based system and water. The power module, which sits under your sink, contains the electrical components that actually deliver power to the disposal motor. While these modules are generally designed to be somewhat resilient, they are not fully waterproof in the way a submersible pump might be. If water leaks from your garbage disposal, a pipe joint, or even from condensation and splashing during regular use, it can find its way into the power module. Because the SinkTop system relies on a connection between the switch and this module, any intrusion of water into that housing creates a dangerous pathway for electricity.
When water enters the power module, it compromises the electrical insulation and connectivity. This leads to overheating damage. Think of it like an electrical short circuit: the water allows electricity to flow where it shouldn't, generating excessive heat in a confined space. The recall records confirm that InSinkErator has received forty reports of this exact scenario—water causing the module to overheat and sustain damage. While no injuries have been reported so far, the risk here is twofold. First, there is the immediate danger of an electrical fire originating in your cabinetry, which can spread quickly before it is detected. Second, even if a fire does not ignite, the damaged module becomes unreliable, potentially leaving you without a working disposal or, worse, creating a shock hazard when you attempt to use it.
This type of hazard is particularly insidious because it often happens gradually. You might not notice small amounts of moisture accumulating inside the module until the electrical components are already compromised. The heat generated by the short circuit can melt plastic parts or ignite nearby combustible materials, such as wood framing or insulation, within the sink cabinet. That is why the CPSC and InSinkErator are urging immediate cessation of use. The problem isn't just that the switch might stop working; it's that the very environment under your sink—often dark, enclosed, and filled with potential fuel sources—becomes a tinderbox if that electrical fault continues unchecked. Addressing this now prevents a minor maintenance issue from becoming a major home safety emergency.
Who is most at risk
The primary group at risk in this recall consists of homeowners and renters who have installed the InSinkErator® SinkTop™ Switch as an accessory for their garbage disposal units. Specifically, anyone who purchased one of the affected single-outlet models—identified by model numbers 76703, STS-SOSN, 78251, or 74300—faces potential danger. These switches are distinct because they mount directly to the sink deck or countertop, serving as an air-activated alternative to traditional wall-mounted switches. If you have a standard garbage disposal activated by a switch on your kitchen wall, you are not part of this risk group. However, if you chose the convenience of a countertop-mounted button for chrome, white, or satin nickel finishes, your electrical setup is directly involved in this hazard.
The specific nature of this risk creates a unique vulnerability profile that extends beyond simple electrical shock. The core issue is that water can penetrate the power module of these switches, leading to overheating and subsequent damage to the outlet located beneath your sink. This means the danger is not just about the switch itself failing; it is about the cascading effect of heat and potential fire starting in a confined, hard-to-reach area under the sink. For many households, this is a high-traffic zone where cleaning supplies, sponges, and wet dishes are common. The proximity to water sources like the faucet and the sink basin significantly increases the likelihood that splashes or condensation will eventually find their way into the switch’s power module.
While no injuries have been reported in the 40 incidents documented by InSinkErator as of the recall date, the potential for harm is serious. The individuals most vulnerable to the consequences of this defect are those who spend significant time in the kitchen, particularly adults who may be multitasking while washing dishes or preparing food. In the event of an electrical malfunction causing overheating, a sudden flare-up or smoke could occur while someone is standing right next to the sink. This proximity makes immediate reaction critical. For elderly individuals or those with limited mobility, the stress and physical effort required to respond to a kitchen fire—reaching for extinguishers, evacuating, or managing wet surfaces simultaneously—can be disproportionately dangerous compared to younger, more agile users.
Additionally, households with young children present a different layer of risk. While the hazard is electrical and thermal rather than mechanical, the presence of small hands near countertop-mounted switches can sometimes lead to accidental activation or interference with the device. More importantly, if the switch fails and causes a fire under the sink, children are often less aware of the danger signs, such as faint smoke or unusual odors, compared to adults. They may also be more prone to touching hot surfaces or outlets that have been compromised by the overheating damage described in the incident reports. Therefore, while the technical failure is electrical, the human impact is felt most acutely by those who are closest to the appliance and potentially least able to manage an emergency response effectively.
It is also worth noting that renters or homeowners who may not regularly inspect their appliances are at higher risk due to complacency. Because the defect involves water ingress over time, it does not always present an immediate warning sign until damage has already occurred. Those who rely on the switch daily without periodic checks of its condition, such as looking for discoloration or unusual warmth, may unknowingly be living with a fire hazard. The risk is therefore cumulative, growing with every use and exposure to moisture until the remedy—a free replacement—is obtained.
How to tell if you have the recalled item
Identifying whether your garbage disposal switch is part of this specific recall requires a bit of detective work, but the process is straightforward once you know exactly where to look. The core issue here isn't about the size or brand of the garbage disposal unit itself, but specifically about the control mechanism you use to turn it on and off. If you have installed an accessory switch that mounts directly to your sink deck or countertop—rather than a traditional switch mounted on your kitchen wall—you need to inspect that specific device. The recall targets InSinkErator® Single Outlet SinkTop™ Switches, which function as air-activated alternatives to standard wall switches.
To confirm if your unit is affected, you must locate the power module of the switch. This is typically the rectangular or square housing connected to the bottom of your sink or counter. Flip over to the back of this power module to find the identifying information. The manufacturer has printed specific details on this surface that serve as your primary verification points. First, look for the brand name "InSinkErator," which should be clearly written on the front of the power module, but the critical data is on the back. You are looking for one of four specific model numbers: 76703, STS-SOSN, 78251, or 74300. If your unit bears any of these codes, it is included in this recall.
In addition to the model number, consider the physical appearance of your switch. These recalled units were sold with decorative buttons and bezels available in three distinct finishes: chrome, white, or satin nickel. While the color alone does not confirm a recall, knowing that these aesthetic options were part of the sold inventory can help you remember if you purchased one of these specific accessory kits. It is important to note that this recall applies strictly to air-activated switches that mount to the sink or countertop. If your garbage disposal is controlled by a switch located on your kitchen wall, your device is not affected by this safety notice, and no action is required regarding the switch itself.
If you are unsure whether your switch matches these criteria, do not guess. The safest approach is to physically inspect the back of your current power module for the model numbers listed above. If you cannot find the switch or cannot read the label, it may be safer to assume it could be part of the batch and contact InSinkErator directly with any photos or descriptions you can provide. Remember, the goal here is simply to verify if your specific component matches the identified risk profile so you can take appropriate steps to secure a free replacement.

What can happen if you ignore it
When a recall notice lands in your inbox or arrives via mail, it is natural to feel a pang of anxiety followed by the temptation to simply put it aside and return to your daily routine. After all, garbage disposals are usually hidden beneath the sink, out of sight and out of mind. However, ignoring this specific warning from InSinkErator carries consequences that go far beyond mere inconvenience. The core issue here is not just a broken switch; it is an active electrical fault that transforms a standard household utility into a potential ignition source. Because water has been found entering the power module, the internal components are no longer protected against moisture intrusion. When electricity meets water in this specific configuration, the result is overheating. This is not a theoretical risk; it is a documented physical reality that has already manifested in real-world scenarios.
InSinkErator has received forty separate reports of this exact mechanism failing. In each of these cases, the ingress of water led to significant overheating damage within the power module and, critically, the electrical outlet located directly beneath your sink. Imagine the confined space under a kitchen sink: it is typically dark, cluttered with plumbing pipes, cleaning supplies, and waste bins. If an electrical component begins to overheat in this environment, it can easily ignite nearby combustible materials. The consequences of ignoring the recall are therefore twofold. First, you risk total destruction of your disposal’s control system, leaving you unable to use a essential kitchen appliance until professional repairs are made. Second, and far more seriously, you expose your home to the very real possibility of an electrical fire. While no injuries have been reported in these forty incidents, the potential for property damage is substantial, and the risk to personal safety cannot be dismissed lightly.
Furthermore, continuing to use a damaged power module creates a cascading problem. The heat generated by the short circuit or arcing can degrade wiring insulation over time, potentially affecting other connected electrical systems in your kitchen. You might start with a faulty switch, but neglecting it could lead to burnt wires, melted plastic fixtures, and smoke damage that spreads beyond the cabinet under the sink. This is why the remedy offered—a free replacement—is so urgent. It is not merely about customer service; it is about interrupting a chain of events that leads from a simple moisture leak to a hazardous electrical failure. By acting immediately, you prevent the minor issue of a wet switch from becoming a major home safety crisis. The cost of waiting is not just time; it is the security of your home and peace of mind.
