PK7500DF2BB General Electric Wall Oven - Instructions

The first step was to determine whether the problem was with the fan itself or the switch. I did this by opening the back cover and using a Volt meter to verify that the fan was not getting power. (I could have skipped this step.)

Next, I unplugged the range, closed up the back cover and lifted the range hood by removing two hex head screws that are just inside and on either side of the top of the opening in the range door. Propping the hood open, I removed the connector leading to the switch, then pushed the switch out the front. Inspection showed that the switch was damaged so I closed up the range and ordered the part from Part Select. Once the part arrived, it was a 15 minute job to unplug the range, lift the top, install the new switch, and close up the unit.

Caution. On starting to install the switch, I failed to unplug the range and my finger brushed one of the hot contacts leading to the switch. Thankfully, I was not injured. Do not repeat my mistake on this issue. Unplug the range even if you're only installing this simple switch.

After opening the Oven door, I removed the glass cover to view and locate the bulb, at the inside, top front of the Oven. Removed the burnt out bulb by pulling it in a forward motion towards the front of the Oven, slid the new bulb into place and the Oven is again functional.

there was one screw holding it on the back wall of the oven. It was easy enough that my daughter installed it with my guidance.

Unplugged the Range and removed the two screws holding down the cook top. You do not need to remove the vent chamber at the rear of the range since the top lifts up about 4 inches. This should be enough room to get your hand onto the plug going to the door switch. Pull off the plug and remove the swich. Pop in the new one, put on the plug, reinstall the two screws and you are done!

Read the thread on "burnt smell" and DO NOT assume it is a burned out element. Follow your nose!!

I used a Trox bit to remove one screw, replaced the oven sensor and reinstalled the screw. The whole project took less than 5 minutes.

This item was listed as fitting my GE wall oven. On arrival it appeared to be the exact part I needed. However upon my attempt to install it I found that the attached male electrical connector was very slightly different from the original part and it would not fit the female connector. At first I thought perhaps I could make a slight modification to the male connector but soon realized that the changes needed were too difficult to make. I tried to locate a matching female connector but no luck. Therefore I decided to use a terminal disconnect tool to unlock the wires from the connector and then I re-used my old connector. It worked! My wall oven is now operational again and my wife is very happy!
P.S., I have been very happy with Parts Select for the availability of old parts and their superb instructional videos. They have helped me make several appliance repairs and are now my first choice

Removed the top and back covers using a nut driver. Removed fan which is on top of the unit. Installed fan sensor board on new fan using torx bit (board can also be swapped from the old fan if you feel this isn't part of the problem). Installed new fan into oven and replaced the covers.
I built a small table out of scrap wood I had making it the same height as the bottom of the oven in order to make it easy to slide out/in and then work on it. If I didn't do this it would have to be a two person job because the oven is heavy.

Opened the screws holding the handle of the door, then insert the new glass and retighten the screws holding the handle back in place.

Changed the Temperature Sensor as you suggested, but the problem of 40 minutes to reach a temperature of 375 degrees F. remained the same.

Remove oven light lens cover, remove the bulb and replace it with a new one.
