Oven wouldn't heat
Easy as pie to do this repair. You first remove the 2 screws holding the element in. Then you carefully pull out the element and remove the wire clips at the ends. Just reverse the process with the new part.

By the way, I ordered my part from parts select on a Friday afternoon and it was on my doorstep Saturday morning..... and this was with regular delivery!
I would buy again in a heartbeat from parts select.

temperature probe insulation broken down so short circuit
As the probe is a plug-in item that would normally be out of the oven, there was nothing more to the repair than checking that the new probe plug fitted the socket and that it was detected by the oven. Then the old probe was consigned to the trash.

Everything checked out, and the probe was used satisfactorily within a couple of days.

Electronic panel
My oven didn't work anymore and it was beeping terribly, with a FO code on it, which meant "Control Panel problem" the only way I could stop the beeping, and still use my microwave on the top, but on same braker switch, was to disconnect a ribbon like wire.. After ordering a new control pad, I called a repair person and asked him, "how do I know for sure if it is the control pad, and not the touch panel which the pad is attached to.? He said the test that he would have done was to disconnect the ribbon like wire and if it stopped beeping, it was the touch pad. Not the control panel... That little sentence saved me $250, so I just returned the panel and ordered the touch pad......it was a easy great fix .!!! I'm so proud of myself for trying and saving money too !

my oven would not heat to proper temp
I slide the range out and unplugged it from the outlet. I removed the back of the oven ( 8 screws ) using a cordless drill and phillips bit then with a phillips screwdriver I removed the oven sensor (2 screws) then I installed the new sensor , reinstalled the oven back , plugged the range in , slide it back into place and that was it. This repair took about 10 mins and the oven works perfectly. Thanks !

Oven was not correctly heating to set temperature
Removed the approximatly 10 screws that hold on both the upper and lower pieces of sheet metal that cover the back of the oven. Removed the screw holding in the temp sensor. Unplugged and removed the old sensor. Plugged in and installed the new sensor (using one of the included adapter wires supplied with the sensor). Put the 2 pieces of sheet metal back on and plugged in the oven.

ovens wouldn't maintain temperature after preheat cycle
unplugged oven. removed 2 screws that hold the sensor in place, then removed the dozen or so screws that hold on the rear panel, unplugged sensor and fed wire through insulation. identified and installed correct harness adapter then fed new wire and connecter through insulation and connected to adapter. installed sensor retaining screws.plugged oven back in and tested function.no dice. unplugged oven once again. removed oven control panel and upon inspection of printed circuit board discovered 3 solder joints had failed. dang. resoldered failed joints and also sweetened up a few others that looked suspect. reinstalled controller, replaced all retaining hardware, and plugged in the oven. tah-dah!! works like a charm now. moral of the story is check the pc board first and save $50 for unneeded pats!!! or buy the controller from parts direct for $260ish. btw a roll of solder and soldering iron from an auto parts store cost around $10, learned to solder on you-tube $0. amazing all the home appliances yo can fix if you're not afraid to take a few screws out and poke around a bit. CHEERS!

Oven sensor caused cooling fan to run continuously. Had to flip breaker to get it to turn off..
Left oven off. Located sensor in pdf manual. Unscrewed mount, pulled sensor out to access connector. Disconnected old sensor, checked continuity(resistance) on ohms with multimeter. No continuity; connected new sensor, screwed mount back into place, turned on oven and baked cookies to check operation & it worked perfectly.

Oven erratic, not heating correctly, timer beeper sounding
The video indicating •unscrew old sensor, •pull wiring, •unplug old sensor, and •plug in replacement was good until I pulled the old one and saw wire nuts behind the small square hole! After some research, I learned that the nuts COULD come through that small hole with use of needle nose pliers. One of the wire nuts had the edges pinched off (chipped) in the process. Then I learned about ceramic wire nuts, which I'd never previously encountered. Very important if you don't want to melt your nuts! I cut and stripped the end of a disconnect plug to the stove wiring and now I have a plug in place; which, hopefully, I'll never need to use.

bake element not working
I removed the bad element - two screws, and tested it on my meter as recommended. The test meter showed it was bad, so I ordered a replacement element from PartSelect. I did check getting a part from a local dealer, and it would have been $10 more. The help and recommendations I recieved on the PartSelect repair forum make it easy.
