GMC275PDS3 Whirlpool Microwave Oven Combo - Instructions

Installed new part

Easily, Removed the oven with help of my grandson, this model is quite heavy. Open the back cover panel, removed the old blower. replaced with the new blower, covered with the back protective panel. About one hour because some screws much harder to reach.

1) Removed the trim pieces (2 screws). 2) removed the 2 screws holding the oven in the wall. 3) Slid the oven out of the wall cabinet 4) removed the back panel of the oven ( 10 screws. 5.) removed the old thermostat (2 nuts) 6.). Installed the new thermostat and reversed steps 4-1

I looked up the problem and determined I needed to replace the limit switch which is inside the back panel. As a 78 year old woman who isn't afraid to tackle these problems I found this easier than most. Just be sure to disconnect the electrical connection if you don't have long enough length to pull oven from the wall cabinet. I won't put any sheet pans in the oven next time I self clean it.

1. Disconnect AC power 2. Remove back with several sheet metal screws. 3. Remove wires from Limit Thermostat. 4. Check Limit Thermostat continuity -- if open then Limit Thermostat is faulty. 5. Remove Limit Thermostat with two screws. 6. Install new thermostat

Removed locking device

I took the new tray out of the box and placed it in the microwave oven.. No tools needed.

Unplugged old element unit and plugged in new element. Took two needle nose pliers and a flexible body. Took about 5 minutes. Works fine. Anybody can do it. Make sure power is off at the box.

My oven (late 90's/early 2000's model) didn't have the flip-down hinge locks shown in the video. It seems Whirlpool/Kitchenaid changed the hinges even though they didn't change the model number of the oven. With my style hinges, you have to put Allen wrenches or bent nails in the holes just behind the hinge pins. Then close the door almost all the way and lift it out to separate the hinges. Spring force holds the nails in tightly until you replace the door. This video was very helpful:

Also, my door had 3 different kinds of sheet metal screws. Two of them have similar heads but different threads. Keep track of which is which for when you put everything back together.

The tech said he used No 2 Phillip's. Once I took the door off and removed the racks I quickly learned a Phillips was not going to work. I am now the proud owner of a Kobslt star and square ratchet screwdriver.

Watched the repair video and started the project. Ran into a problem when trying to remove the interior panel off the door to reach the broken interior glass. On this model Kitchen Aid there is another section that is screwed in holding the exterior glass pieces in place. It prevents the interior panel from coming off the front of the oven door. So we had to flip over the door and unscrew the glass retaining bars to get the interior panel off and reach the glass. This allows the entire door to come apart in pieces so you have to carefully line up everything to re-assemble the door. Part of the issue with this is some of the retaining screws are not very long so you have to press the pieces back together to make sure the screw will catch in the original hole. We had to do this twice to ensure the interior door glass was laying flush on its mounts. A bit fiddly for sure, and if I was working alone it may not have been successful. But at least we know how the door is put together!

we live in Venzuela the ordered windows come to us via a forwarder in the US, one glass (the outer glass) still has to arrive. Very pleased with the service of PartSelect, one glass was in stock, the inner glass had to be ordered with the manufacturer. This glass is on its way and will arrive here in Venezuela by the end of May. As I have to travel to Europe next week, I will install both glasses upon my return somewhere in August next. I will sure inform you about the repair which will be done by myself.

Thanks to video provided by PartSelect the repair was fast and easy. My second experience with an appliance repair with parts and video from PartSelect. I am a happy customer.

I watched the video on the product page and followed it step by step. Not difficult at all.

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.
