Loud pop Our microwave was running, then there was slight "pop" and the whole control panel was out. I checked all the circuit breakers, and the outlets in the immediate area. Any suggestions? Thank You Howard

Your oven has a plug or is wired to a 120volt line. Check this. You may need to Reset circuit breaker.

That unit shows that it takes 15 or 20 AMPS to run. What is the breaker amperage on the circuit where it is plugged in? Is the breaker a GFCI? You can tell by looking for the two buttons on the circuit breaker or the outlet.

I would check or replace the door switches, also check for condensation on the main control panel.

Something is shorted out. Leave the breaker off until you find it. You need an ohmmeter to find it, but look for the black marks for a hint.

Hi,

Here is a tip that will help you to figure out what is wrong with your Microwave Oven....

mcdevito75 here, Sounds as though the control board could be faulty, check with any appliance repair center in your area.

It is possible that the interconnection link(s) between the two sockets in the duplex outlet have blown apart. Turn off power at the electrical panel for this circuit, remove the outlet from it's box, and check the interlink on both sides. If obviously burned, replace the socket. A better option is to run another duplex cable from the breaker box to the outlet from a new breaker, cut the interconnections on the new socket, and wire the new cable to the isolated part of the socket. This supplies full power to each half and allows both units to run at the same time.

It's very easy to do if you can get the circuit board. Take the two screws out of the plastic fan grill and pop it off. There should be one screw above the control panel. Take that off and the panel should pop off by slightly pushing up. Unhook all the wires and unscrew the board. Put the new board in and your done.

Two possible causes.

First (and most likely) the circuit is being overloaded. This kitchen circuit may be shared with another appliance (like the refrigerator) which is drawing enough power when both are running to trip the breaker. A Typical kitchen circuit is 20 amp with #12 wiring. So an 1800 watt microwave might draw 13 or 14 amps while a fridge compressor kicking in can surpass 7 amps before it levels off. If this is an older home the kitchen may have a 15 amp circuit with #14 wiring. If the circuit is a 20 amp you will have to split the appliances onto separate circuits. (Under code a kitchen must have a minimum of 2 separate appliance circuits). If it is a 15 amp you might be able to split them as well or may be looking up upgrading the breaker and the wiring from 15amp #14 to 20 amp #12 (but you could still have the same problem).

The other possibility is a short or loose connection. If splitting appliances onto their own circuits doesn't fix this you would probably want an electrician to come in and check for other underlying causes which could represent a fire hazard.

Hope this helps.

sounds Like an electrical fault in the Micro, Sorry but this is broken.... If this is within warranty (do check as some warrantys are for 3 yrs or more) get the manufacturer to replace/repair it for free. you could get it serviced, but it is probably cheaper to buy a new one.
