GMC305PDB0 Whirlpool Microwave Oven Combo - Instructions

Small, older female with limited hand strength here. Turned off the power to the stove. Removed the baking element from the oven wall with a screwdriver, snapped out the old one and snapped in the new one. 5 min tops. The broiler was a bit more labor intensive as the rusted and/or stripped screws did not want to come out. Used some liquid wrench, gripping grit, and a power drill to remove, but once the screws were out, it was another easy snap off/snap back in process. Had some screws on hand to replace the stripped ones. Broiled a steak that night with the new red hot broiler. So happy. This repair just saved me approximately $1800 to replace a 28 yr old drop-range. Very happy with this purchase.

Unplugged old element unit and plugged in new element. Took two needle nose pliers and a flexible body. Took about 5 minutes. Works fine. Anybody can do it. Make sure power is off at the box.

Several professional appliance repair people told me I had to get a new oven (double, no less!) because "they don't make that hinge anymore." That would have been a $4-5K investment to replace two ovens that both work fine. I'm not generally a DIY person, but was inspired by a FB page I follow called "Handy Women." I got the model number out of my oven, googled "replacement hinge for ____," and found it on this site right away. $120 and about 1 week later I had my hinges. I found this video in the comments on this website that shows (without narration) exactly how to change the hinges.

The only mistake I made that cost me some time had to do with the little pins you have to put into the hinge to remove and replace the oven door. They were missing from the old hinges, and it didn't occur to me to use the ones that were in the new hinges (hadn't unboxed when I started.) I used threaded bolts that were the right diameter and length. They slid right in, but then when I went to take them out, it was an ordeal with WD-40 and an Allen wrench. Then it still didn't occur to me to look at the new ones, so I went to the hardware store and bought two more things the right size without threads. Of course when I took the new hinges out of the boxes they already had the little pins in them. Annoying and time consuming rookie mistake, but my oven door now closes just fine, and I'm getting a ridiculous amount of satisfaction from my little repair job!

We had to remove screws from the vent covers above and below the microwave, then there were 2 screws (one on each side) that attached the microwave to the oven. Once all of the screws were removed we had to pull the microwave out. Then we pulled the light cord out, removed the burnt out light and installed the new one. Then reversed the steps.

removed door from oven, took all screws off door to remove glass, put new glass in place, put oven door back together, put oven door back onto the oven

unscrewed the oven door, took off the entire door, pulled apart the glass pieces and replaced

Ordering the part online was easy. It arrived in a timely manner. I found a terrific video online showing how to install the terminal. It was so easy. Thank you for the great instructional video.

Removed the small metal panel covering the main power terminal in back of the electric range. Removed the nuts holding the red, white and black electrical wires from the range using the appropriate socket (there will be two nuts on each bolt end). Removed the two screws holding the main power terminal block with appropriate screw driver. Connect the new main power terminal block to the range using the two screws. Reconnect the red, black and white electrical wires coming from the range using one nut for each wire. IMPORTANT: do no over tighten the nuts because the bolts could snap. Reconnect the pigtail and secure the small metal panel covering the main power panel.

Ordered a new motor. Removed the outside trim of the oven-microwave combo. 2 screws at the bottom of the trim. Removed the screws that held the combination micro and oven unit in place. Removed the top and bottom black plastic grill of the microwave. 3 screws each. Pulled the entire unit out about 1 inch exposing the screws at each side of the microwave that hold it in place.
Snapped off the top control panel which exposed the wiring connecting the control panel.
Unplugged a couple of wire harness units to free the control panel.
Be sure to label the units to know which goes where during reassembly.
Remove the microwave unit from the housing and place it on its side.
Remove the metal plate that houses the motor. 4 screws hold the motor in place. Disconnect the 2 wires from the old motor and you are ready to install the new motor. Be sure to TURN OFF THE POWER to the unit at the breaker box and remove the turntable from inside the microwave.

I removed the Oven door, unscrew 10 screws, open up the dor case, clean all glass levels, replace inner glass, reassembled the door, reinstalled the door to the appliance.

Read the instructions in installation manual to remove door. Kept removing screws. Was surprised to find two panes of glass between the inner glass and the outer glass. Cleaned all the glass (4) and the inside of the door. Looks brand new. Be careful with the insulation; be sure it is pushed back or it will show from the outside.

Removed door to see what happened to the spring, ordered new spring and door frame on line and replaced parts. Had to replace door frame as it broke while removing it.
