GSC278PJT4 Whirlpool Microwave Oven Combo - Instructions

I am not a big do-it-yourselfer, so maybe I might have found this more difficult than expected. When I first looked at the oven before ordering the part, I saw a couple of screws and it seemed like an easy task. However, I found that I had to remove to whole door first, which was actually easy. Then I started to remove the case. Then I removed several layers of a puzzle. Oven door had 3 pieces of glass and 3 metal brackets. The installation video was for a completely different oven. Although I got out the broken glass easily, I had difficulty reassembling. The oven diagram for the parts was even deceiving. I had to involve my spouse and after an hour of cursing everything, we finally managed to get the thing back together. Whoever designed this oven must have been a deranged German scientist. However, everything is back to normal and I probably saved a couple hundred bucks for a repairman.

I did some research on blogs and identified the thermal fuse as likely culprit. Ordered part from PartSelect.com, but had to call the 800 number because the parts diagram doesn't show this fuse, just the thermostat. The fuse is located on the back of the oven, so it must be removed from the cabinet, but that wasn't a huge project. There are a bunch of sheet metal screws holding the top and back covers that must be removed. The fuse is held on by two screws and has two wire connections. Getting the stove out and disassembling is the hard part, but not really difficult if you take your time. I used a foot stool that was about the same height as the bottom of the oven and just slid the oven out on a piece of cardboard. Make sure you turn the power off before starting.

I was able to convince a local mechanic that he could do this after watching it done four times. The most difficult part was unscrewing and taking out the oven to get to the back. He suggested since this has happened everytime I used the self-cleaning feature, that I cut a hole in the wall for easier access (tongue-in-cheek). The most difficult part was dealing with the extended warranty service plan - this is covered, but they could not find a technician to do this. Then I found out they don't pay mileage so who would want to come out to a rural ND ranch to repair an oven?

There are hinges on the door that need to be lifted up to take the entire oven door off the appliance. The screws are taken off of the door to get to the interior glass. The cracked oven door was simply taken off and replaced by the new one and the screws were put back and the door was placed by hooking it onto the appliance and the hinges were dropped down. Simple as that!

Removing the door was the first challenge but once the door was off it was a matter of disassembling the door to get access to the interior door. If you remove all pieces and line them up in the order that they are removed you have a good chance for success.

I went to the source of power on the stove and noticed one of the terminals had come loose from the terminal block and had shorted out against the cover of the terminal junction. After prying the loose terminal off cover I ordered new terminal block and received it the 2nd day. I removed the old terminal block and replaced the part in about 10 minutes..Thank you Parts Select for your easy to find diagrams and quick delivery.

Unscrewed the old thermostat took off the conectors then replaced with new one, and screwed it back on.

Removed the old element by taking out two screws and replaced the new unit using the same screws. The delivery time on the new element was very quick-about two days. Thanks.

Ordered the part from partselect.com. I was amazed that it arrived the next day! It was the easiest repair I ever did. Took out 2 screws, unplugged the wires from the old element, plugged the wires into the new one, and replace the screws. Done.

Killed the power to oven, removed oven from its enclosure (its heavy), removed back off oven and the part that needed to be replaced was right there. After that simply reverse the procedure. Honestly hardest part of whole job was remembering what i did with the screwdriver after my last home repair job. The oven is heavy you may need help.

Ordered a new cooking tray and it was shipped within two hours. Packaging was excellent and well protected.

I ordered it from PartSelect one evening and had the replacement glass one day later. It was the quickest service I have ever experienced. Now, I can continue to use my microwave. Thanks for such great & timely service.

Honestly, I was afraid to order from this website, but after reviews, I placed my order, and 2-3 days later, my glass tray was replaced in my Microwave! I was freaking out because you just cant go back to Sears or Standard Brands and get a new one...everything is on-line. Im VERY happy.

Lifted out the chipped one, inserted the new one. Pretty simple.

Contacted repair person on line and explained the problem. Person suggested testing the thermal fuse. Checked for continuity and there was none indicating the fuse was blown. Ordered new part and installed. Everything working again. Only problem was that the new part did not have the same connection as the old one on one end. Made substitution and it worked.
