Harry for Model Number JMV8186AAS The microwave turns on and will run for about 40 to 50 seconds then trips the circuit breaker. Tested the magnetron, diode and capacitor. All tested good. Replaced the magnetron and diode but still does the same thing. Circuit breaker still trips It is a dedicated circuit. Any ideas?
Answer Harry, what you can do is if you test the amp draw of the unit as it is running, the amp draw should exceed the limit of the breaker in order to make it trip. If it is drawing excessive amps, then you may want to look at the transformer. If it is not drawing excessive amps, you can try plugging the microwave into another outlet to test if it is the microwave tripping the breaker or a weak breaker. Read More...
