GMC305PDT3 Whirlpool Microwave Oven Combo - Instructions

Gas Oven would not work without door shutting all the way. New hinges fixed the problem! Removing Superba oven door was the challege. Kitchenaid has their manuals available online which you can look up using the model # available on side of oven door. It contained instructions for door removal which required two pins (one in each hinge) inserted in the hinge holes for the door to release when you pull up and out on it. Nails may be used to replace the pins but the tricky part is removing the nails from the old hinges to remove them from slots in oven door. I used a 12 inch piece of small PVC pipe as a lever, inserting the pipe on the exposed portion of the hinge. This released the nails. The oven door must be taken apart which required removal of screws on the inside face, top and bottom of oven door. It went easily back together and the problem was solved.

It was a matter of swapping out the old door with new door. In all, it was a snap . Around 10 screws to take it apart and a few brackets to hold it all together.

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

The oven is a KitchenAid convection oven with 4 panes of glass. The front, two inner glass panes that aren’t “touchable” and the interior glass that is the one that takes the heat from the oven and which you can clean easily - this is important because the descriptions of the glass all say “inner glass”. This is door #3 in the diagram that measure 10 x 22”. Which I cracked when I was pouring water into a pan to create steam for bread baking (lesson learned).

Because of the age of the oven, to remove the oven door it was necessary to place “pins” (we use medium screws) into the hole behind the door latches. Then were able to lift off the oven door. (We saw some videos on YouTube)

We placed the oven door on the counter top and removed ALL screws that held the door at the bottom and around the casing - KEEP these screws separate by where you’ve removed them so you replace them into the proper section when you reassemble the door. Each glass you remove has slots that hold them in their proper places. I recommend taking a picture BEFORE you take out each glass as there are brackets that need to go in proper order and you don’t want to forget the order.

We had to flip the door over in order to CAREFULLY remove the casing and access the different inner glass sections (took the opportunity to really clean them). Gathered the broken glass pieces into a paper bag and vacuumed the fragments. Then we were able to place the new interior glass from PartSelect, and reassemble the oven door. It’s perfect!

This took some time most likely because it’s a very old oven and you need to be methodical. I was just glad to be able to get the part - not yet ready to replace the oven.

BTW, originally I was guided to order glass #7 which is one of the inner glass panes that you cannot touch - unless you take apart the oven door - The exchange for the proper door was handled very quickly and easily. Hope this helps.

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.

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

Disconnect the sensor harness and checked resistance on the sensor,should read around 1100 ohm I only got 25.The sensor is mounted in the oven cavity back wall below upper element,the door must be removed. Unscrew 2 Philips head screw,unhook the harness,install new sensor,reconnect harness,install screws.

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

Set the new one inside the microwave

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

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

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.

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

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
