Is your slow cooker tripping your circuit breaker several times a day?

Join the club! This might be hard to believe, but this is a very common issue among the people that own this appliance.

I know that having problems with something you bought to make your life easier can be very frustrating. Especially if you’re hosting a dinner soon or need to feed your family.

But don’t worry, you came for answers and that’s exactly what you’ll get. Below, I’ve prepared a list of 5 easy ways to fix your unit and get everything back to normal.

When your slow cooker keeps tripping your breakers all day long, you’ll want to try checking your power cord, testing your wall outlets, or replacing the appliance’s thermal fuse. If that fails, you can also try replacing your circuit board and looking for damage to the pot.

#1 Check Your Power Cord

Let’s start off by making sure that your main power source is not to blame for this situation.

I know it might be hard to believe that something that looks as sturdy as your power cord could sustain enough damage to trip your breakers, but it’s in fact quite possible.

Now, I’m not saying that moving it around carefully will do it in, but simple actions, like keeping it bent at a sharp angle against a wall could create a lot of trouble as time passes.

Something like this could cause enough damage to render your slow cooker useless or dangerous to use, as partial cord breakage can result in short circuits and trip your breakers.

Always try to keep your power cord properly stored and avoid sharp bends

Solution: Depending on your appliance’s model, you might be able to detach the power cord from the unit without too much effort. If that’s the case, try using a different cord.

I know not everyone has spare slow cooker power cords lying around in their home, but fortunately, getting a replacement is very easy. But before spending any money, I’d recommend talking to your friends and family to see if they have a cable you can borrow for testing.

Provided they do, feel free to plug your slow cooker into the wall outlet with the new cord and see if your breakers stop tripping. And if they don’t, that’s also ok. All you have to do is Google search for your unit’s make and model and find the right cable for it on any online marketplace. They’re usually under $10.

Note: If your appliance does not have a removable power cord, testing for damage might be a little more complicated. In cases like that, you’ll want to call a professional, so they can check for any irregularities without damaging the unit.

#2 Test Your Wall Outlet

Assuming that you’ve determined your power cord is ok, let’s move on to the next link in the power supply chain – your wall outlet.

This is one of the most critical parts of using your slow cooker as it’s what supplies the electricity it needs to get the job done. In most cases, your home’s wiring should be working perfectly, and you never have to worry about a bad outlet. But occasionally, things can go wrong and problems might arise.

In these cases, a multimeter is your best friend

A faulty wall outlet is not only concerning due to the damage it can cause to anything you plug into it, but also due to the fire hazard it represents and the larger picture it paints.

Solution: If you suspect that your slow cooker is tripping your circuit breakers due to a bad wall outlet, confirming your hypothesis is as simple as connecting the appliance elsewhere.

For example, let’s say that you always use the unit in your kitchen, and you notice something’s off. In that case, carefully disconnect the cooker, take it to another room in your house and plug it back in. If your circuit breakers are no longer tripping after a while of cooking, the original outlet is likely to blame.

Now, if you want to be even more precise and feel like taking on a challenge, you can always take the time to learn how to use a multimeter to test an outlet. It’s much easier than it sounds, and it can help you rule out a larger failure within your home’s wiring.

#3 Replace Your Thermal Fuse

Having covered everything related to the power supply, let’s not move on to check on your thermal fuse.

If you’re not sure what this is, I’m happy to give you a quick explanation. In a nutshell, this is a small component within your appliance that is responsible for measuring its internal temperature and regulating the cooking process accordingly.

It’s through your thermal fuse that your unit can prevent catching on fire and ensure that your food is cooked at the temperature you’ve set.

In most scenarios, the component works great, and that’s that. But sometimes, it might fail or blow due to electrical overload, excessive strain, and other factors. This could explain why your slow cooker is tripping your circuit breakers, or why it might be running too hot.

Now, having your thermal fuse blow is actually not a bad thing – it’s meant to do that to protect your appliance. However, in some rare cases, it might only blow partially, which would allow the cooker to keep working without a temperature failsafe.

Events like this can cause an electrical overload as time goes by, which can manifest itself as tripped circuit breakers, and other more concerning issues.

It can be worth taking the time to learn your way around fuses

Solution: If you suspect your slow cooker’s thermal fuse needs replacing, here’s how you can change the component yourself:

  1. Carefully disconnect your slow cooker from the wall outlet, and let it cool down completely.
  2. Remove any food or liquids inside the pot and turn the appliance upside down.
  3. Undo the screws holding the bottom cover plate in place.
  4. Remove the cover plate to expose the unit’s wiring and internal components.
  5. Locate the fuse (if you don’t know what it looks like, please check the image above for reference).
  6. Inspect the component for damage. You can use a multimeter to test the conductivity between all the parts within the appliance. If there is none, your fuse is likely blown.
  7. Look at the part number of the blown fuse or do some Google searching to find the right replacement. If you’re lucky, your nearest hardware store might have what you need.
  8. Solder the new fuse onto the slow cooker and test for conductivity again.

If a bad thermal fuse was to blame, your slow cooker should no longer be tripping your circuit breaker.

#4 Replace Your Circuit Board

Yet another reason why you might be in this situation, is a faulty or fried circuit board. This component controls everything within your appliance, from the LED indicator lights to the cooking process and the temperature measurements.

It’s basically your appliance’s brain.

When it works normally, you’re able to cook delicious meals and use your cooker as expected. But when anything affects it, you’re in for a world of trouble.

You’re probably wondering what could cause enough damage to fry your slow cooker’s circuit board, and the answer is simple – power surges, electrical overloads, and high temperatures. Any of these elements can cause permanent damage to your appliance and would explain why your slow cooker is tripping your circuit breakers.

Solution: While there are no one-size-fits-all signs for a fried circuit board, you can always keep an eye on certain indications. If in addition to your current situation, you notice that your slow cooker is not turning on, the LED lights are working funny, or there’s no heating whatsoever, chances are this is why.

Sadly, unless your appliance is professional-grade or very expensive, you’re better off buying a new cooker, as replacing the circuit board might not be cheap. Ideally, you want to set your repair budget at a maximum of 30% of what you paid for the unit.

#5 Look For Damage

Lastly, let’s cover something that might seem very obvious, but can also be easily overlooked.

There’s a good chance that your slow cooker is tripping your circuit breakers due to solids or liquids leaking onto its internal components. These appliances are designed to last a long time and are typically very sturdy, but they’re not indestructible.

If there are any cracks in your unit’s pot, some of your food could slip through and cause short circuits and electrical overloads.

This is not very common, but hey… we’re trying to cover all bases here, right?

Solution: If you suspect your slow cooker is broken and needs repairing, you can check your warranty to see if it’s still active and send the appliance to your manufacturer. They should get back to you quickly and offer an acceptable solution.


Having your slow cooker keep tripping your circuit breakers can be very frustrating and even dangerous, as there’s always a fire hazard.

Hopefully, this piece has helped you see that, in most cases, addressing the most common causes behind this is very easy and quick. More often than not, replacing your thermal fuse, and checking your power cord and wall outlets should do the job.
