GMC305PDZ0 Whirlpool Microwave Oven Combo - Instructions

This was more difficult than anticipated - probably because I'd never done it before. Once I got the door off (I didn't have the proper pins and used nails but didn't realize they had to be headless) I found all the screws, which were relatively easy to take out. I was surprised that the thermal door glass was obscured by two other panes of glass. It took more disassembly than anticipated and a few false starts when reassembling, but all in all it got done. I was happy that a job that would have cost probably $300 or more ended up getting done for $40 plus my labor - which isn't worth much these days. I'd certaily do it again.

Set the new one inside the microwave

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

After 22 years the oven stopped heating in the middle of a meal prep. The fault code was F3 oven temperature problem. I googled the codes and found PartSelect described the problem and the repair and part needed. I received the oven sensor part, then turned off the power, used a screwdriver to remove 2 screws (had to find the right size flat head screwdriver to fit the square holed screws and they were pretty baked on after 22 years of use), gently pulled the sensor and wiring through the back of the oven. I used a needle-nose plier to pull the plastic connector through the insulation, then unsnapped the connector, snapped in the new sensor connector and pushed it back through the oven wall. Pretty simple repair, took me longer to find the screw driver than the actual repair.
Thank you PartSelect for making it easy and saving me a repairman visit!

XLarge pizza tray in a 450 degree oven - slam the door & CRACK. Replacement glass arrived on Saturday - VERY FAST DELIVERY. Placed 2 allen wrenches in both hinges - open the door half way & lift up. Place the door on a towel. Removed 6 screws, lift & seperated the inner oven covering, removed the broken glass & cleaned inside & replaced with new glass. More time was spent cleaning & coming up with a tool to fit into the hinge

Once we figured out to use small allen wrenches in the small holes of the hinge to enable us to lift the door off everything went smoothly. Took out six screws, lifted out the hinges - inserted new ones, replaced screws and replaced door. Yipee

Followed a video. Followed instructions

Thanks for the excellent service. Parts cheaper than local stores, arrived on time, with NO PROBLEMS.
Installation, probably 30-minutes. Took the opportunity to clean glass, door panels, etc while disassembled, so used about an hour. Oven cleaner was a big help in the cleanup.
Very rewarding project and it saves changing the unit and and refitting the countertop.

Cut the power. Undid the screws to the element. Popped off the old element replaced with new,put screws back in turned power back on and Shazam it was up and going

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.

With just the removal of a few screws I was able to replace the glass with the side benefit of cleaning the outter glass that had gotten dirty over the years with use. This is a simple project that all can complete.

Fool proof.

Removed the door from the oven. Undid all the parts above the inner glass door. Installed the inner glass and reassembled the door. Reinstalled oven door.

Just put it in

Well, the instructions on the computer site were very easy to understand, however, the difficulty lay in the fact that we were 2 78 yr old people and getting to the inside the oven, lifting up the element so that we could see where it should be connected and get it connected was a task. We had to get down on our knees and then get back up. That was a chore within itself. But, the instructions were easy and clear.
Bottom line if us old people can do it, anyone can.
