Re: microwave oven

Well it moslikly the problem is a bad switch , there located insde the unit, it's posible the plastic made like lever that turns the switches on or off is jamed or broken.
To check them unplug the unit , open the cover, with an ohm meter check to see if they turn on or off. Basic electrician rull, most of them don't know this.
If all seem to be ok, double check, It's mostlikly 99% your problem , the other percentage is a bad board cause by a bad keypad or board, witch it's very small.

ps if it's the keypad or board like all other 99% of population tuss it out, keep in mind don't complain there to mutch air polution your also a cause of the problem.

I replaced the light bulb under the unit on my microwave and went to turn it on and it tripped the circuit breaker and smoked the control panel. The only fuse in the unit is still good. Any thoughts?

< - Please let me know your full model number from the tag on the unit and I can can give you the repair information you need.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

The lights can can be inoperable or stuck on or stuck in "night light" mode. Sometimes this will similarly affect the fan operation or inside light, too.

Micro won't work after boiling water under it all day

I am not sure what you mean by boiling water under it all day. If it was under the unit, it probably shorted it out and it won't work. If you were using it constantly to boil water, you may have overheated it. To be safe, please unplug it and call the manufacturer.

Turn table won't turn on ewave microwave oven

Almost certain if microwave still heats a bad motor or gear issue inside the unit--if unit will not heat the safety switch in the side that the door engages is the cause of the wheel or platter not turning--prevents unit from use if door open.

Got a short at or in the switch assembly that is causing this and unit would have to be unpowered and checked to see if one or both switches are bad.

Won't run

see this causes and fix it. God bless you
No Lights or Power, Unit seems Dead First check is the main fuse of the unit. On countertop units, you will need to take the shell off. The fuse will be close to where the cord comes through into the unit. OTR units, this main fuse is usually behind the control panel or possibly behind the vent. Usually the fuse is obvious if blown, otherwise test with an OHM meter, if open, replace fuse.
Some brands will also have a thermal cut-off fuse in the incoming voltage line to the control board. Older Maytags and Samsungs have this fuse in it. This thermostat looking fuse is usually above the oven cavity somewhere under the outside shell. Sometimes you can get to it through the vent of OTR models. Test with an OHM meter, replace if open.
Test the switchs door see diagram

If it's not heating at all, the magnetron is to blame.

Does not heat

The magnatron unit has malfunctioned. You should be able to replace that unit if you're mechanically apt, although with the price of microwave ovens, you might just as well get a new one that's under warantee.
