KMHS120EBS3 Whirlpool Microwave - Instructions

Ordered a new motor. Removed the outside trim of the oven-microwave combo. 2 screws at the bottom of the trim. Removed the screws that held the combination micro and oven unit in place. Removed the top and bottom black plastic grill of the microwave. 3 screws each. Pulled the entire unit out about 1 inch exposing the screws at each side of the microwave that hold it in place.
Snapped off the top control panel which exposed the wiring connecting the control panel.
Unplugged a couple of wire harness units to free the control panel.
Be sure to label the units to know which goes where during reassembly.
Remove the microwave unit from the housing and place it on its side.
Remove the metal plate that houses the motor. 4 screws hold the motor in place. Disconnect the 2 wires from the old motor and you are ready to install the new motor. Be sure to TURN OFF THE POWER to the unit at the breaker box and remove the turntable from inside the microwave.

I removed the microwave to install a back splash and found the support edge on the backplate had broken off and was missing. I searched for parts for the microwave and found them on PartsSelect.com. Easy to order, and was shipped promptly.

Once the part arrived, install was simple, lining up the existing holes. The only hard part was setting the microwave up on the bracket due to the weight and awkwardness of the microwave.

Overall a very simple repair.

After removing the over-the-range unit (no small feat!) I had to figure out how to open the case (good puzzle!). Capacitor had already discharged, so it was very easy to reach in, pop the old fuse and install the new one! As per your advice, I found out I was a "28%-er"! Upon re-installation, the microwave "sprang to life"!! Thanks, "Part Select"!! I was already shopping around for a new machine! (Now if you could only tell me an easier way to re-mount this heavy beast over the stove!!!)

Removed the face plate above the door (2 Phillips screws.) Removed existing filter and replaced with the new one purchased. Reinstalled the face plate.

Removed one screw lowered glass cover removed burned out bulb replaced with new one put glass back reinstalled screw. Dune 5 minutes back in business

I simply lifted out the glass rotating plate and inserted the new support. How complicated can that be?!!!!!!!!!!!!!!!!!!!!!!!!!!!

This is an under the counter microwave. Simply removed the two screws holidng the vent grille on top of the unit, lift out the old charcoal filter, clean the vent fan exit surfaces then replace the filter and put the vent grille back. Be careful to not drop either of the two screws after one is installed as you will have to take the grill off and start the screw installation again unless you have a magnetic to retrieve the dropped screw. An easy five minutes at most to change.

when I opened the back cover of microwave, the diode was kind of blackish blown, since there was light bulb and fan were still working, i thought it could be problem with any one of the components like; magnatron or capacitor or diode, so first replaced the diode and mica at the end of the magnatron duct, there was problem with door switch as well. i fixed that too. Now it is working. It cooks bit faster, Wondering why?

I was sent the wrong fuse by you. I had to procure a fuse in another manner. Very disappointing. The repair was simple. It just took longer because of the failure to send the correct fuse.

Open compartment, installed bulb, closed compartment

took it to Buttermore appliance in Auburn Indiana and he changed the fan and added another fuse

Took the front off and behind a plate was the fuse, so I replaced it for what good that did!!!

I unscrewed the filter cover, replaced the charcoal filter and replace the cover. The other wire mesh filter slides right into place. You sent me the right parts for my filter replacement on my microwave. Easy install. Thanks

The problem I have with changing the bulb is my microwave is an overhead one and therefore I cannot tip it on its side to easily replace the bulb. I have to drop the lid down and carefully install the new bulb from underneath.

Replaced light bulb.
