GMC305PDZ4 Whirlpool Microwave Oven Combo - Instructions

I took out the old chipped dish and replaced with the new dish...

My electric oven is a built-in. First I turned off power to the oven.

Then, I removed the oven door as instructed by Kitchenaid, next I removed the screws that held the concealing-sleeves on each side of the oven opening. Slid down the sleeves, loosened the exposed screws on each to allow the oven to slide out. Slid the oven out abut half way to expose the top. Removed the metal sheeting from top of oven to expose area where door latch assembly was secured. Removing the sheeting was made easier by removing the screws on each side of the control panel and lifting the panel out of the way.

The latch assembly is held in place by two screws through the front of the plastic venting. Identified the connections to appropriate points before I removed the wiring, removed wiring and attached to points on the new latch assembly.

Secured latch assembly to plastic vent, secured sheeting to top of oven, placed conrol panel back in place, pushed oven back and secured with screws.
Slid sleeves into position, secured with screws and replaced oven door.

Open oven dooor. With a philip screw driver remove the gasket plate at the bottom of the oven holding the seal gasket. pull seal gasket away from oven seal channel and clean surface before installing new seal. align seal pins to to seal channel holes be sure not to twist the seal insert pins in one at a time.Install lower bracket however you may want to wet the fray ends of the seal gasket prior to screwing in plate to keep the ends from moving away from the bracket when scrwing it in place.

Removed four trim pieces; removed four wood screws holding oven in cabinet housing; slid oven out (weighs about 150 lbs and takes two people and a bench to rest oven on. Oven will pull all the way out but not much further because of the electric cord.); Removed back sheet metal cover (bunch of small metal screws); removed wires from bad unit, unscrewed the bad unit and screwed in the replacement unit.

A screw on the botton of the door was very inaccessible and difficult to remove. The rest of the process was flawless.

The instructions from another customer was helpful. I concur with another comment I read while researching this proceedure. What Idio-- would design a microwave that required pulling the unit from the wall and removing the top panel just to access. It is good idea to unplug the transformer and capacitor wires before proceeding. I also googled a schematic to see the parts layout. Remember not to touch the bulb with your fingers. Use a cloth or paper towel.

I used a Google search to show how to access the area behind the front panel. There was a folded paper copy with a schematic and wiring diagram in that space.Then I used a multi-meter to determine which of the THREE micro-switches was causing the problem. I called your help line and ordered a replacement switch. The switch was delayed in transit so your agent credited me with the cost of shipping.

When the part arrived, it had three terminals instead of two as shown in the on-line picture but that did not cause any difficulty in using it. It took about 20 minutes to remove and replace the old switch.

All seems to be working well now.

Finding which of the THREE switches was the problem was the most difficult part of the repair. All three "clicked" but the defective one did not click as easily. It needed to be depressed more than the door latch can would provide. Old age?

Oven stopped heating after attempting a self cleaning cycle. Problem turned out to be failed thermal fuse component. This is an easy repair and well worth the attempt given the replacement cost of the oven.

First step was to locate and shut off the two circuit breakers supplying power to the oven. Then I locked the panel to ensure someone didnt re-engage the breakers while I was working on the unit. (Lock out / Tag out).

Second step was sliding the oven out of the cabinet - this unit is located below a cooking top and was just the perfect height to allow a furniture dolly to be used to support the oven as I slid it out.

The unit is 'hard wired' (i.e. no power plug) so it can only be pulled out so far from the cabinet, but there was sufficient reach to allow access to and removal of the sheet metal cover at the rear of the oven to expose the thermal fuse and the read wiring. I proceeded with care, assuming the power was still on and once the terminals of the thermal fuse were exposed I performed a voltage measurement to ground on each side of the fuse to ensure power was in fact off.

Then I used an insulated pliers to gently remove the wire harness at each side of the fuse, and once the wires were removed I performed a continuity check of the suspect fuse, and confirmed it was an open circuit (i.e. failed).

Removal of two more screws allowed the fuse to be removed and the new fuse was installed, reversing the procedure.

This was followed by replacement of the rear sheet metal and finally sliding the oven back into its place in the cabinet using the furniture dolly. This is a single oven but still very heavy and has some sharp sheet metal edges likely to cause cuts if not handled with care so the dolly and a second set of hands (and good gloves) are nice to have.

Finally, after inspecting the oven door gasket and other air vents around the outside of the oven to identify suspect causes of the overheating event that tripped the fuse, the air vents above and below and within the door were cleared of dust-bunnies and other debris that had collected, possibly causing interference with the air flow that cools the area in between the oven and the cabinet. This blockage may have been the root cause of the fuse failure - i.e. the air did get too hot back there and had the fuse not tripped it would have been dangerous. The door gasket looked fine although its also an easy replacement and does not require oven removal.

The new part fit perfectly - it was a different design than the original part that shipped with the oven but appears to function perfectly so no complaints. The trip temperature is identical to the OEM part based upon the nomenclature on the back of the OEM and the replacement fuse part.

Unlocked the power panel and turned on the two breakers to the oven, set the clock and checked operation and its functioning great now.

Have not run a self cleaning operation since the repair but that is the next step and now that those door vents are clear I suspect that the fuse wont trip again.

Lesson Learned: Check those vents for obstructions.

Similar oven selling at discount because its the end of the model year is now priced at over $1100. Fixed our unit for $50 and the added cost of a $20 furniture dolly that I already wanted to buy.

Give this repair a try its a piece of cake and well worth the effort.

I have a rental and the tenant called. She said that she had a repair man out to fix the oven but he couldn't~that it needed to be replaced as he could not get parts.I contacted your company via phone and the person was so helpful~he asked the problem, looked up the model and advised me on this!It works like a brand new oven!Thanks you

Simply removed door with screw driver. Cleaned glass while apart and installed new hinges . Parts were delivered on time and fit perfect. I would recommend this company to everyone

easily IDed parts; ordered, here 3 days later. very convenient. no hassle. no wasted time going from place to place or calling everyone in yellow pages.

I just placed the tray in and was done. The kicker is that i cannot use my microwave without the tray. so i was without my microwave for 2 weeks before i called parts select. they were quick and fast.

Removed 4 screws top and bottom of the outer door panel. Remove outer door, then the two inner panes of glass. You are then able to remove the broken inner glass. Carefully slide the new inner glass into place, being careful not to tear the insulation. Once new inner glass is in place carefully replace the two inner glass panes and secure the screws. Replace the outer door and the top and bottom screws and that's it!

First we had to take the oven door off, which proved a bit tricky. There was a release pin which was hard to find and release. Then we had to unscrew the screws and take the glass and inside of the door off to access the spring hinges. Replacing the hinges was pretty easy, as was reassembling the door. The door snapped back into place and voila! the door stayed shut.

Just had to remove the screws holding the outer part of the door on (didn't have to take off the entire door). Using the other door spring (most models have two that cross) as an example, the new spring was fairly easy to place. Only problem is that the new spring was made from a smaller gauge metal and is not nearly as strong as the original, making the door feel heavier when opening/closing than before. The difference with and without the 2nd spring is barely noticeable. Had I known that they were making the parts cheaper now, I would'nt have bothered fixing it at all.
