MMV6180WB2 Maytag Microwave - Instructions

easy to replace, just the same as cleaning the turntable and placing back in the micorwave;

Unplug appliance. Remove total of 7 phillips screws from sides and front of bottom panel . Panel front drops down, remove one socket screw and socket. Now have access for lineman' s pliers to unscrew bulb base. Reinstall socket, replace bulb and 7 panel screws. Restore power.

Part of the support was missing. I had to remove the two switches and put them in the new bracket
Had the switches reversed and started blowing fuses. Reversed them and changed the fuse and it started working.

Washed the glass tray and put in the microwave oven. Easy..

We needed a phillips head screw driver to remove the single screw holding the light bulb cover in place.
Removing the old bulbs was a little work, because they had come loose from the sockets. We unplugged the microwave, so we could grip the sockets with a tool. I think my husband used a needle nose plier for this.
The new bulbs screwed in easily, and then we refastened the light bulb cover with the phillips head screw driver.

Turn off power supply at breaker . Replace old bulb with new bulb .

Two Mounting plates # PS12074431 were sent to me and both do not fit.
Model number MMV1175JZ-0
Serial number TRX-17. 24546
Manufactured April 2020
Contacted Maytag and even sent pictures to show the problem with alignment of the mounting plate not fit in the back of the microwave.

Spouse just screwed in the new bulb and reinstalled the light cover plate with the two screws. Took under a minute. Works great.

Husband replaced the bulb

I ordered another one and placed it inside the microwave. It works and fits perfectly. I received the order exactly as scheduled.

Cleaned the interior of my microwave, cleaned the new plate and simply added to the turn area.

PartSelect website indicated replacing the high voltage power supply diode is the solution for "no heat" 99% of the time, but the diode was OK. There is more info at the website concerning the case of "loud buzzing and no heat" indicating the magnetron needs to be replaced. As an electrical engineer with knowledge of microwave components, this was also my best guess. However, getting to the magnetron is not the easiest job, but it's not impossible. You also have to be careful to bleed off any charge stored on the high voltage power supply capacitor. Luckily, I found my KitchenAid service manual tucked away inside the unit since I couldn't find it online.

Unplug the microwave. Then remove the six screws that hold the lower panel which has the light bulb cover and a couple of vent filters. The light bulb sockets are on a fixture that is connected by a quick connect electrical connector. Disconnect that and the whole panel is free to access the bulbs. My bulbs were very fragile and trying to twist them out resulted in the glass twisitng loose with the base still in the sockets. I needed to use a needle nose pliers to remove the bases and then I replaced the bulbs and put every thing back together

Looked up the Whirlpool Co. and ordered the part. It was quite simple. Arrived in 2 days and I simply placed it in the microware. It was very very easy!
