I removed the screws holding the bezel, removed the control panel frame, unhooked the four wires from the timer, and removed the timer. I cut the glue holding the circuit board into the frame and removed the circuit board. I unsoldered the faulty encoder switch, dissassembled the switch, determined the correct specifications for the switch, and ordered the nearest equivalent from an electronics supplier. I modified the new encoder to accept the shaft from the old encoder and I re-drilled the circuit board to fit the new encoder. I then soldered and wired the encoder, reversing the wires to correct the direction of rotation. I then reinstalled everything and added the knob purchased from partselect.com. Now it works. Tough repair - not for the faint of heart or those of average skill. But for the record, installing the knob was of course child's play and took only a moment.

slide out stove remove rear cover (6 screws) to access sensor plug . remove two screws from inside oven area and remove part,replace in reverse order.

Unplugged the stove and unscrew the 2 screws on the thermometer inside the stove and unplugged the white plastic in the back of the stove and I had to put the new extra piece that came with the sensor kit as it was needed because the socket were different.

I live in a small town in South East Colorado. We have just a Walmart and Sears and a few smaller hardware stores. I checked all of them to try to find this 25 1/2 inch Fluorescent Light Bulb, and nobody carried one. I would have had to drive 70 miles to find one. The Service of Partselect was wonderful and the bulb showed up in just 4 days. I was lost without this light. I have bought a few other items for my older appliances in the past from Partselect. com and was very happy with the service and how easy the web page is to navigate. .

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.

I started by removing the door, then trying to remove all of the screws in the oven casing. Of course the very middle screw in the bottom of the oven was rusted and dammged by use. I had to use a drill bit and remove the old screw. After dissasembly of the oven casing, I found that the lip that supports the gasket was rusted and burnt away about 3/4 in. I placed the new gasket in and found that when closed it covered this defect and sealed. I reassembled and cheked for operation.Ok! Imortant--remove the elements before removing oven casing.

1. Turn power off and loosen and remove screws. Pull out sensor from mounting hole and expose wire connector. Remove old sensor. Select appropriate wire adaptor and reconnect the sensor. Carefully push connector through hole and secure with screws removed previously. Turn power back on and cycle oven to make sure oven operates properly. If you have an oven thermometer it can be used to compare set point of oven to thermometer to make sure readings are the same. All done! Happy wife can now bake cookies again and now I can go back to man cave for other projects!

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.

replaced heat sensor

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!

I located the temp sensor (top left). Removed the 2x Phillips screws and slide the wire out until the plug is thru the opening taking care not to pull to hard as to damage the end that you not going to replace. To install plug it in and push the wire thru and secure with 2x Phillip screws.

Removed the ice brucket,
Removed the light shield by releasing one screw using a nutdriver.
Replacing the bulb and reinstalled the light shield.

Your web site is one of the best and most helpfull service sites I ever used. Just wish that in the future you will ship parts overseas.

First I called a repairman and left a message. That was 3 weeks ago. So, I 'googled' the error message and determined what part I thought I needed. Ordered the part on Wednesday evening and it was there when I got home from work on Friday. I unpacked the part, got a phillips screwdriver and then watched the repair video on your website. About 20 minutes later I pushed my stove back in place and the flashing said 'set time'. Then I checked both ovens, and have since used both, and everything works!!

The sensor is mounted in the top right side of the oven.An extra long screw driver helps to avoid damage to the sensor when replacing it.The connectors were the opposite to the old sensor and I did not see that there were adapter cables included. It might help to connect or tie these together as I only expected the sensor and did not look for adapters.I had cut the wires and used wire nuts when I found the adapters.The repairs works fine.

Oven sensor replacement was easy. Thermistor was installed in less than 15 minutes. After installation STILL had "F3" error message. Harness was ok, "Clock" or ECU needed to be replaced. "Computer" is obsolete, no spares available, some companies will rebuilt for $400+. Since the stove was going to the landfill I had nothing to lose by taking the "Clock" apart. It has one chip that is probably the power supply and control chip, another chip is an EEPROM with 128 bytes of storage and the last is a darlington chip that controls the relays. Cleaned up everything that looked like it needed cleaning with alcohol. When I reassembled the unit the pins for the thermistor harness felt loose, so I took it apart, again, and found cold solder joints on all four pins. It must have been there all along but plugging and unplugging the harness finally broke out the solder so I could see it. Soldered the pins back in and now it all works. It's worth a try if you're getting the "F3" message. If the relays on your stove aren't working it would be a good idea to replace the darlington chip. Good luck.
