Refrigerator Keeps Tripping GFCI? Why and What to Do

Quick answer: A refrigerator that keeps tripping the GFCI is usually one of three things: a GFCI that’s oversensitive to the electronics in modern fridges, moisture or a worn part leaking a small current, or a faulty GFCI outlet. Don’t fix it by plugging into an extension cord or removing the GFCI. Test the outlet first, then call an electrician if trips continue.

This problem got far more common recently, and there’s a clear reason why. I’ll start there, because it changes how you should think about the fix: if you’ve just remodeled your kitchen and the fridge started cutting out the same month, the new outlet is probably the reason, not a broken fridge.

Why So Many Fridges Are on GFCIs Now

GFCI (ground-fault circuit interrupter) outlets cut power when they sense current leaking somewhere it shouldn’t, such as through water or a person. The National Electrical Code has required them in kitchens for years, but the rule used to cover receptacles serving the countertop.

The 2023 edition changed the wording to cover kitchens generally. According to the appliance industry group AHAM and the electrical inspectors’ association IAEI, that means the receptacle behind a refrigerator in a home kitchen now needs GFCI protection too. Plenty of fridges that ran fine for years on a plain outlet ended up on a GFCI after a remodel.

Why Your Refrigerator Keeps Tripping GFCI Outlets

1. The GFCI Is Oversensitive to Modern Electronics

Modern fridges use switched-mode power supplies and variable-speed compressor drives that operate above the normal 60 Hz. AHAM, the appliance manufacturers’ association, says the GFCI standard doesn’t set trip limits for those higher frequencies, and some GFCI makers set thresholds that make devices oversensitive.

In a UL Solutions test cited by AHAM, nuisance tripping happened on all three appliances tested across ten GFCIs, and no hazardous electrical conditions were found. In other words, the fridge was fine; the GFCI simply reacted to it.

2. Moisture or a Worn Part Is Leaking Current

Repair technicians commonly trace genuine trips to moisture reaching wiring or to a defrost heater that’s starting to leak current to ground. These trips often happen at the same point in the cycle, such as during defrost.

I’d treat this cause seriously. A GFCI doing its job on a real leak is a safety warning, not a nuisance. The trick is the timing pattern: trips that line up with defrost are worth a technician’s visit.

3. The GFCI Outlet Itself Is Failing

GFCIs wear out. An older unit, or one in a damp or hot spot behind the fridge, can start tripping on almost any load.

4. The Circuit Is Shared or Overloaded

Sometimes the “GFCI trip” is really a breaker trip, or the GFCI protects other outlets too. A fridge sharing a circuit with a microwave or kettle can trip things for reasons that have nothing to do with ground faults. See can a refrigerator be on a 15 amp circuit for how manufacturers want fridges wired.

How to Narrow It Down

1. Press Test, then Reset on the GFCI. If it won’t reset, or won’t trip when you press Test, the outlet is likely faulty.
2. Note when it trips. Random trips point to sensitivity. Trips at the same time every day or two often line up with a defrost cycle.
3. Plug a different appliance into that outlet. If a lamp or kettle trips it too, the GFCI or wiring is the problem, not the fridge.
4. Check for water. Look for leaks from the ice maker line, drain pan or a damp wall behind the fridge.
5. Write it down. When you call an electrician or appliance tech, the timing pattern saves them a lot of guesswork.

In practice, steps 1 and 3 settle it more often than not. If a lamp trips the outlet too, you’ve ruled out the fridge in two minutes. If only the fridge trips it, I think the fairest next step is a newer GFCI before blaming the appliance.

What Not to Do

• Don’t use an extension cord to reach a non-GFCI outlet. Whirlpool and Frigidaire say not to use extension cords with their fridges at all.
• Don’t swap the GFCI for a regular outlet yourself. If your local code requires GFCI protection, removing it can violate code and void insurance coverage. Some states have changed this rule locally; AHAM lists Georgia, Iowa, Massachusetts, North Carolina, Oregon and South Carolina among them. An electrician will know what applies where you live.
• Don’t keep resetting a GFCI that trips with water present. Fix the leak first.

What an Electrician Can Do

A licensed electrician can test the outlet and circuit, replace a worn GFCI with a newer unit, check for moisture in the box, and confirm what your local code requires behind the fridge. If the fridge itself is leaking current, an appliance technician can test the defrost heater and wiring.

Older GE manuals said use of a GFCI was “not recommended” for their fridges, while current Whirlpool and Frigidaire guidance simply says to reset a tripped GFCI. My take: given how the rules differ by state, this is one problem where a professional opinion is worth paying for.

Frequently Asked Questions

Should a refrigerator be on a GFCI outlet?

Under the 2023 National Electrical Code, the outlet behind a fridge in a home kitchen generally needs GFCI protection, though some states have changed this locally. Ask a local electrician what applies to you.

Why does my fridge trip the GFCI but not other appliances?

Fridges contain motor drives, power supplies and a defrost heater. These can leak small currents or produce high-frequency signals that some GFCIs react to, even when nothing is unsafe.

Can a bad defrost heater trip a GFCI?

Yes, according to many appliance technicians. A heater that’s starting to leak current to ground can trip a GFCI, often during the defrost cycle.

Can I just replace the GFCI with a normal outlet?

Not without checking your local code. Where GFCI protection is required, removing it can break code. An electrician can advise on compliant options.

Is a GFCI that trips with my fridge dangerous?

Not always. Many trips are nuisance trips. But because a trip can signal a real leak, it’s worth having the outlet and fridge checked rather than ignoring it.
