Whirlpool microwave does not switch on - no power

Whirlpool EASYTRONIC DOUBLE EMISSION SYSTEM M404 microwave

Hallo everyone,

Our nine year old boy decided to open the door and use a small piece of rolled up paper to "close the lock" without having the door shut with the result that the door could not be closed anymore. However the clock on the display was still working fine.

I then used a nail to "pull back" the "hook / switch" into place so now the door can be opened and closed as usual.
However I am not able to switch on the microwave anymore, it does not respond at all; it appears to be dead. No clock, no light, no nothing ..
Meaning it is plugged in but when I press the Start button nothing happens.

I opened the device by removing the white metallic cover. On the inside located directly behind the Start button I spotted a glass fuse with light blue, orange, dark blue and brown circles around it. It seems to be OK still. Little metal wire looks fine.

Else I can not see anything wrong with the device. Is there another fuse somewhere?

Kind regards
Wolfhard
P.S. I could not find my product in the list below. So I chose the first.

A problem with a door switch or door switch mount (like this one) will cause the fuse to blow when the door is opened or closed.

There may be a second fuse inside.

You also need to check the door switches and latches to be sure all the debris is out.

There is often a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

Powers off immediately after starting


My immediate reaction would be to cut your losses and buy a new unit as sooner or later you will run into a part that is no longer available.

Suggest you pull the plug out, remove outer cover and place a cup of water into the micro. Set power to minimum then switch on and take note if the fan works or not. If not, switch off immediately and have it replaced(magnatron will burn out if left to run without fan.)

Hello there:
If it It sounds normal,and seems to run ok but there's no heat When the microwave sounds okay, but there's no heat, one of the internal door switches, the high voltage circuitry, or the megatron or power inverter or the circuit board may have a problem. To resolve this problem, you need the assistance of a qualified appliance repair technician. ok hope this helps best regards mike

Our microwave went dead. It's only three years old. My husband put some chicken wings in, closed the door, and everything went black. We plugged in a nightlight in the power source and it worked. Any ideas...


a few possible causes,
1, the high voltage fuse,
2, the high voltage capacitor
3, the slow blow fuse ( normally found on a small pcb inside unit)

other than that, check the door switches and maybe the x former.
good luck.
