Display Very Dim & Broil not working

  • Customer: Roger from Oxford NC
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Nutdriver, Screw drivers

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.

The display faded away almost to nothing

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.

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.

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..

clock/temp control not lighting up

We turned off the stove at the breaker panel. Took off the front top panel of stove and replaced the replacement board. It had three attachments to plug in. We then replaced front panel and turned on the breaker. The stove worked perfectly. It is very nice to have a clock and temperature reading visable again. Part Select was very easy to order from and we received our part within a couple of days. Will certainly suggest them to friends and will use them again.

Oven LED Display blank

Open oven door
Remove two sets of four screws underneath the LED display
Remove stove handles (pull off easily - no tools needed)
Lower flat plate width of oven and about two inches deep should be able to drop out from under the clock display.
Remove face plate over clock.
Unscrew four screws holding clock unit down.
Undo two electric connectors and the thin ribbon connector - the thin ribbon connector is different - the ribbon comes loose and the black plastic connector stays in place on the board.
Press the thin ribbon connector ends inward and pull up to detan ribbon on old one and then to insert ribbon on new one.
Reverse the rest.
Not too bad!

Time and temp not displaying

I have only two things to add to the other repair stories on this site: (1) Unlike the ribbon cables inside desktop computers, the ribbon cable on this range is entirely separate from the connector, which is permanently attached to the clock assembly. There are clips on the top of the connector at each end. Push them in and raise them gently to release the ribbon cable. (2) There are two Molex connectors attached to the clock assembly. The pins for one of them were bent on the new clock assembly I received. Before installing it, I spent some time gently coaxing those pins back into alignment. Use your fingernail, and be patient.

Cut of electricity. Opened the oven door and removed some screw that were over the door that let a plate be removed. Then that let the part drop down that was holding the clock. I removed 2 screws that was holding the clock in place, unplugged the 3 connectors that feed the clock, attached the 2 screws back in that held the clock, put the part back up in place, added the plate and was done. Turned the power back on. I was delighted when I saw the clock light on. Easy to install.

Remove four screws behind control knobs. Remove four hex nuts under control panel (open oven door to locate). Pull control panel down and out. Remove two hex nuts holding clock assembly. Remove three wire connectors on the old clock assembly and carefully insert on new clock assembly. Reverse instructions to re-assemble. It's a breeze to do! Took longer to get my tool box than the time it took to replace the clock assembly.

LED Display to dim to read

I first turned the breaker off. Then removed the screws under the display with the oven door open. Then removed the side screws. Then removed the trim kit for the microwave which exposed 3 more screws. The middle one with the Micro Door open. The complete display panel then was removable. I took a digital picture of the 2 wire and 1 ribbon connectiors (I know-anal). Then removed the 2 wire groups-struggled somewhat with the ribbon connector until I realized by trial & Error that the 2 little tabs on the sides only pull upward, releasing the ribbon. Removed 4 nutdriver screws to remove old display-installed new one in reverse fashion. Then I CLEANED everything I could reach it was so dirty! (I live in the desert,duh!) I just paid great attention to how it came apart and it was relatively easy. The best part is that I didn't have to remove the Oven/Microwave unit to do the repair.The new part works perfectly, thanks!

This is the second clock I have had to put in this unit in about that many years. The first time I disassembled far to many things. This time I knew to only unscrew the front panel and side triangle plates. The process was much faster the second time. I hope this is not a chronic problem though.
