You tried heating up last night's leftovers in the microwave, but the microwave tripped the dang breaker. Again.
We imagine that’s getting annoying, and you’d like to fix it, yeah?
The cause is one of two issues:
- The microwave is overloading the circuit
- The circuit breaker is worn out.
Let’s explore each of these issues and the solutions to each, shall we?
Microwave is overloading the circuit
An electrical overload is when there’s too much electrical current flowing through a wired circuit.
For example, let’s say you have an circuit rated for 20 amps (amps being a measurement of electrical current). If 30 amps runs through the 20-amp circuit, the breaker will detect that there’s too much electrical current and trip to prevent an electrical fire.
For your case, you may have been running too many electrical appliances on the circuit at the same time; the microwave was just the catalyst for pushing the circuit over the limit. Microwaves can use about 12 amps, so running it alongside any other appliance can easily trip a 15-20 amp breaker.
You can tell if the microwave is sharing the circuit with other appliances if the breaker that tripped does not specifically say “microwave” next to it.
Circuit breaker is worn out
Circuit breakers, like all things in the universe, break down eventually. And when breakers wear out, they tend to trip easily.
- Unplug all electrical devices on the circuit that the breaker tripped.
- Reset the breaker (flip it to OFF, then ON). You should hear a definite “click”. If the switch flops back and forth and there is not definite “on” or “off” position, the breaker is probably bad.
