Have paid over 400 dollars to electricians who "investigated", replaced circuit breaker and still not fixed. Breaker flashing 2 red lights (parallel high current arc). The breaker for this dedicated circuit is a Dual Function AFCI/GFCI Circuit Breaker (Siemens, 15 amp). Arc fault circuit interrupters are prone to nuisance tripping, which is probably what youre experiencing. Some of the causes of this problem. Unless you run a dedicated line for the micro, it'll be connected to the SAC and on the GFI. The breaker for this dedicated circuit is a Dual Function AFCI/GFCI Circuit Breaker (Siemens, 15 amp). But AFCIs do tend to be sensitive and prone to flipping off. The microwave works fine for a few days, then suddenly it starts tripping the breaker within 5 seconds of starting it, no matter what is in it. The lifespans of Arc Fault Circuit Interrupters (AFCI) and Ground Fault Circuit Interrupters (GFCI) are between 15 and 20 years. How long do AFCI breakers last?

Had it happen to a car headlight and my headlights started to blink. This is a form of protection that guards against sparking (arcing) and thereby reduces the chance of fire. For some reason this seems to be an issue more common on newer models. Seem like the afci breaker you have right now affected by the microwave frequency ,try to replace the afci breaker. Known as AFCI (arc-fault circuit interrupters), these devices are designed to sense sparking (arcing) that occurs when electricity jumps between faulty wire connections. I reset the breaker, everything came back up, no problems. If your microwave is plugged into a GFCI breaker outlet and it keeps tripping, the outlet itself may be at fault. They sometimes allow current leakage that can trip the AFCI and create a situation where a circuit breaker keeps tripping without a load. Started unplugging various components, compressor, evaporator fan, finally the defrost heater before it could be plugged in without tripping the breaker. AFCI, GFIC, Magnetic, Thermal Magnetic, or a common trip breaker. And at what they cost, I may go broke! This technology monitors the circuit for signs of an arc and is designed to prevent electrical fires. Since the appliance is plugged into an outlet, it is necessary to have AFCI protection.

AFCI tripping. Also check the micro cord with a high reading ohm meter, if there is any leakage from the hot or neutral to the grounding conductor, it will cause the AFCI to trip, also inductive kick back trips happen right when the inductive load is turned off, if it is tripping when the load is turned on then it could be a grounded neutral in the circuit feeding it. The breaker ahead of that circuit protected the circuit from over-current (too much load) and short circuit (fault). Arc Faults An arc fault happens when exposed faulty wiring touches, causing the electric current to arc at the meeting point.
