Why a Microwave Keeps Tripping the Breaker

It ’ mho hard to imagine a home without a microwave oven. They ’ rhenium handy for cooking breakfast, lunch, dinner, warming up snacks, heating water for hot drinks, soup, and lots more. They ’ ve become so commonplace in our homes that we don ’ metric ton even realize how many times we might use them in a individual day .
We do notice, however, when they don ’ deoxythymidine monophosphate employment. That ’ sulfur when everything changes. One of the most coarse problems with a microwave is tripping a surf. When a microwave trips the circuit breaker, preparing meals on the spur of the moment becomes a more difficult and drawn-out march. Something that we ’ re used to taking 5 minutes in the microwave becomes 30 minutes in the oven. This takes a wholly new horizontal surface of plan and makes us want our microwave back .
In order to get your microwave back up and running so you can get on with your day, let ’ s expect at why a microwave keeps trip the surf .

The Circuit is Overloaded

The bare answer is the tour is overloaded. There are respective causes for this, including :

  • Too many things plugged into the circuit
  • Faulty GFCI (Ground Fault Circuit Interrupter)
  • Circuit Breaker failing
  • Bad Microwave oven – pulling too much current

Let ’ s front at how to troubleshoot the problem and keep your microwave from tripping the surf .

Too Many Things Plugged into the Circuit

Circuits are rated for 20 amps and microwave ovens draw 12 amps. If you try to run multiple appliances on the circuit at the same fourth dimension, it can exceed the racing circuit ’ mho rate and trip the circuit breaker .
For safety, your microwave should be on a dedicated circuit. A dedicated circuit serves lone one appliance. nothing else can draw stream from that circumference. This protects the circuit, the surf, appliances, and your home. Repeated tripping can cause the circuit breaker to wear out oklahoman and can damage the appliances. Overloaded circuits can overheat the wiring, placing your home at gamble of electrical arouse .
Check the tour surf to see if the microwave is on a dedicate tour. Look in the breaker box for a surf labeled “ Microwave ”. This means the microwave is on a give racing circuit .
If you don ’ t have one labeled for the microwave, check to see which surf is tripping. If it ’ south labeled “ Kitchen ” or something alike, then the microwave is not on a dedicate circumference. This means early appliances are drawing current while you ’ re trying to run the microwave .
It is good if the microwave doesn ’ deoxythymidine monophosphate partake a circuit with other appliances such as toasters, chocolate makers, mixers, etc. The current reap of multiple appliances can exceed the 20 amps the breaker is rated for. To keep the surf from tripping, be sure not to use another appliance at the same time as the microwave .
If the microwave is on a dedicate circuit as is tripping the surf, it could be a faulty circuit surf, mercantile establishment, or microwave oven .

Faulty Circuit Outlet

If your microwave is plugged into a GFCI breaker exit and it keeps tripping, the exit itself may be at defect. Try resetting the GFCI wall socket. If the GFCI keeps trip, there could be something else on the circumference causing the problem or you may have a defective GFCI.

Try another exit to see if the problem goes aside. If it does, then the trouble is with the GFCI release or circuit. You can take farther steps to test the GFCI or have an electrician test the circuit. For more information about testing a GFCI exit, see our article Why Does my GFCI Outlet Keep Tripping ?

Faulty Circuit Breaker

Try a using the microwave on a unlike circumference with nothing else running on that lap. If the microwave works fine on other circuits, and you ’ ve already ruled out a GFCI, then you might have a defective tour breaker which will need to be removed and replaced. Consult an electrician to replace the circuit breaker .

Faulty Microwave

If the circuits and breakers are finely and the problem is not with the GFCI, then you probably have a bad microwave oven. There are several ways to test the microwave .
Operate the microwave on a higher adenosine monophosphate tour such as an wall socket in a garage or workshop, or a known give circuit. Most probable, the microwave oven is faulty if the breaker trips. If it doesn ’ thyroxine trip, then you need a dedicate circuit for the microwave .
If the microwave trips the circuit breaker, and it ’ s on a give circuit or nothing else is plugged into the tour, and you ’ ve tested the circuit, then you could have a defective microwave .
The microwave could have faulty switches in the door, a bad magnetron, defective home circuitry ( such as a diode, capacitor, or transistor ), or a waste blend. Repairing internal faults is dangerous and requires especial training and tools. Do not try to repair a microwave oven unless you have this train. Take it to a attest technician or replace the microwave oven .
If it ’ s an older microwave it would be best to replace it to a more efficient whole. If it ’ s a lower-priced microwave it can actually cost more to repair it than buy a new one .

Conclusion

Microwave ovens are convenient but they can be aggravating when they tripper breakers. The most common causal agent for a microwave to slip the surf is running excessively many things on the circuit at the like fourth dimension. It ’ mho good to have a dedicated circuit specifically for the microwave. This will require an electrician. besides, be sure to check the outlets and breakers.

If you don ’ t have a dedicated lap and you can ’ t have one installed, then be certain that you don ’ thymine run the microwave and any early appliance at the lapp fourth dimension. This will help keep the current pull back on the circumference to 12 amps .
If using the microwave on a consecrated circuit doesn ’ triiodothyronine solve the trouble, and you ’ ve tested the outlets and breakers, the trouble is most likely the microwave itself. The microwave should be repaired or replaced. If it ’ s an older microwave, then it ’ s probably best to replace it for a more effective whole .
