WMH31017FS0 Whirlpool Microwave - Instructions

Based on other similar posted repairs, I purchased the bottom switch. Upon removing the control panel to replace the switch, I found the blue 22 gauge wire was broken at the spade terminal. This wire had been crimped to the terminal along with a 14 gauge wire. Apparently the force to crimp the thicker wire weakened the smaller wire at the terminal. I stripped the end of the small blue wire and reattached it to the thicker wire using a solder iron and solder. The repair fixed the problem.

Removed the top screw holding the control face. Lift up on control face and tilt outward to unplug wires and remove green ground wire screw. Place unit on a flat surface and remove flat wire plug by squeezing tabs and lift up slightly then remove flat wire. Unscrew screws holding PC board. Then reverse order the install of the new PC board and install unit on to microwave.

Unscrewed glass panel, removed old bulb, cleaned glass panel and installed new bulb. Screwed panel back into place.

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!!!)

Put in the charcoal filter buy taking two screws out and replacing.

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

Put new plate in and it was fixed

Replaced tray. No tools needed.

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 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!!!
