GMC275PDQ08 Whirlpool Microwave Oven Combo - Instructions

Removed upper oven panel above oven door,removed back cover & replaced electonic control panel. Everything works again

Removed all terminals and block mounting screws. Repaired one burnt terminal and reassembled. Replacement part was an exact fit and reassembly whnet very well.

The replacement turntable we received was an exact duplicate of the original. It was as easy as rinsing the new turntable, taking the old turntable out and putting the new one in.

My husband took the back off and replaced it. The repairman suggested pulling the range out into the floor to run the self clean mode. I have owned several such ranges and have never had to do that and won't now. Easy Clean Oven Cleaner will be the next thing I use.

cut power off and placed sturdy table same height as bottom of oven in front of oven. removed trim screws. pulled oven out onto table. removed top cover and panel on left side . tested transformer to be sure it was bad. then replaced transforner

Ordered a new one, put it in place in less than one minute.

Remove rear panel - remove sensor from inside - unplug from rear - reverse to install - did not fix problem

Removed and replaced boiler element

The replacement of the blower was an easy repair. Just had to remove two back panels of the oven and the blower was then very accessable. Just remove the two electrical wires and then three screws and the blower came right off. Put the new blower on with the three screws and replaced the 10 or 12 screws holding the back panels and the job was complete!. The difficult part of the job was removing the combo unit from the cabinet to access the back panels. That part took some effort. Had to build a platform to slide the oven out onto after I disconnected the electrical feed wire (#6 wire) located in a junction box in my attic. Once that was done, the actual blower replacement was simple. The turntable motor was a different story...Although replacing the turntable motor was going to be as easy as replacing the blower motor, I couldn't access the underside of the microwave without disassembling the whole combo unit cabinet! That was very disappointing to me that Whirlpool didn't make that part easier to access, so I didn't replace the turntable motor. Too bad but we are just going to live with the turntable not turning!!

Part arrived in timely manner and placed it in microwave oven.

removed double oven from wall removed cover from electronic cover and replaced part. realitivity simple repair

Set the new one inside the microwave

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.

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

I found that what was keeping the old temp sensor electrical connection attached to the stove-side connection was a little tab. It wasn't obvious that that was the thing that was keeping the connection secure but there weren't any other alternatives. So pushing the tab up with the metal probe (just a narrow rigid metal wire) allowed me to pull the connection apart.

All this takes place way at the back of the oven so its difficult to fiddle with a screwdriver and the retaining screws at arms length. Putting a bit of scotch tape around the screw to keep it attached to the screwdriver kept it from falling off. My hand was a bit shaky extended like that so that was the way to go.

Bottom line, if your oven won't reach or hold the temp you dial in on the control panel it's the temperature sensor. Now if I set it for 300 deg. that's what I get.
