W30400PR Jenn-Air Wall Oven - Instructions

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 "Computer" is obsolete, no spares available, some companies will rebuilt for $400+.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.

Bought a pair for needed door hinges for replacement. Found a DIY video on You Tube showing technique to replace. Door removal was a bit awkward but hinge replacement and door reinstallation was as detailed in video. Could not nor would not have tackled this project without video. Premium quality parts sent and received within days of ordering. Wife happy therefore so am I.

We followed the DIY stories of others (like this one):

Turned off the breaker to the stove and removed the 4 screws under the control panel. The trim strip and the end caps did not have to be removed. The control panel was lowered just enough to clear the upper edge and then tilted forward so the connectors could be disconnected. Two screws holding the display in place were removed and the new display swapped out. Reassembly was disassembly in reverse.
Had to be gentle about unplugging and plugging in the ribbon cable.
Very happy with PartSelect product, delivery and website help.

My son removed the switch panel and unpluged
the switch. Then he replaced it with the new
switch fasten back the panel and turned the
power back on and everythiing worked fine.

Spoke to your very helpful staff, who advised me that a likely problem was the oven sensor. I took a chance and ordered the part, which came promptly. Your service video for the part was most helpful in my decision to try the part. Installation was a breeze, but it was the oven controller board that had failed and not the oven sensor. That called for a service professional, who ultimately fixed the problem. Your service though, was excellent and I would highly recommend you to others.

I contacted a local appliance repair store who didn't know what I was talking about. I looked online and the store called me back to tell me the part would probably be $75.00. I took the broken part out of the door frame and found the exact part online at your site, and ordered it for $14.00. Received the part within 2 days and put it in in 10 minutes.

I watched a You Tube video,removed and dismantled the door, installed the new hinge. I forgot to remove the small pin which is similar to a rivet. When I tried to close the door it bent. Eventually, I remembered the shipping pin and pulled it out with any damage. Believe it or not, I had read about the shipping pin on customer comments on PartsSelect...Good luck, it is relatively easy!

Turned off breakers to oven. Removed two screws that held oven in cabinet. Removed oven door by opening slightly and pulling up on door. Pulled oven out 1/3 of way. Took out four screws on top of control panel. Took oven light switch off by unscrewing holding ring. Removed temp knob on right by pulling. Removed start / stop knob same way.Removed glass straight out. Removed four screws that held elecrtonic clock conrtol board. Unpluged three wire plug from right side and the nine wire plug from the left side. Worked board out at and angle. Went backwards to connect and replace board, screws and door.Slid oven back in and tested oven after turning breakers back on, worked like new.

Took screws out of the back on the side the sensor was on, unplugged it & took out the two screws on the inside of the oven to release the sensor. Put new sensor in place with the two screws & used one of the adapters to plug in the new sensor. Put screws back in the back panel & turned on the oven which unfortunately is still 50 degrees low. Need a new clock with computer which is out of stock & unavailable. I was an electrician for 25 years so didn't experience any problems. It was a cheap thing to try.

Turn off the electrical breaker before starting! Open the oven door & remove the 4 silver hex head screws under the bottom of the control panel with a 1/4 " nut driver. Pull out on the bottom of panel. This will access the clock assembly. Unplug the ribbon cable by pushing in & up on the small clips on each end of the connector - this is a little tricky but not that difficult. Remove the two small connectors and remove the two clock assembly mounting screws. Reverse the procedure for installation. This corrected the problem with the broil element not working - apparently the electronic clock assembly was the problem there as well.

There were only 4 screws to remove to take off the thingy that houses the electronics portion. Then, there was a ribbon connector and two push on connectors to unconnect. Unscrewed the 4 nuts holding the faulty Assembly in place, replaced with new Assembly, and reversed the process.

That easy. The only problem was making sure which of the parts we actually needed.

it took me longer to get my portable screwdriver from my shop than to remove four screws from the panel and two screws from the clock assembly and to unplug and replug wiring , then reassemble the panel

I removed two screws holding the element in place. Carefully pulled the element from its mounting throught insulation to expose the two wires connected by electric wire clips. I removed the clips and searched the part online using google. Part Select was provided as the top source. I ordered the part and it was delivered in two days. Taking care to thread the connection through the insulation, I was pleased to have installed it in about 5 minutes. All tools were still out and ready for use. Thank you for your service

First I took the screws off of the top hood which can be found right underneatch, this allowed me to access the panel bolts and unscreww them. We then got it far enough so that we could easily replace the old with the new and plug things back in and we were good to go. I am not sure but we must have save hundreds of dollars in a repairman.. This website is awesome..

Turned power off to oven, removed control knobs, took out four screws under panel. Removed four 1/4" sheetmetal screws. Removed front cover, Removed two additioanl screws that held front cover to corner bracketts, Removed two screws that held clock to plate, removed each wiring harness and pluged into new part, unplugged wiring ribbon from old part plugged into new. reassembled. Turned power back on and tested and we had light!!!One repair company was going to charge us over $400 to make this repair!!!
