WM27460W Jenn-Air Microwave Oven Combo - Instructions

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.

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.

Very easy to repair, but you have to be able to pull your stove out. Two screws in the oven and then remove part of back cover of oven and one plug from there. Simple to do, but did not fix our problem. We are waiting repair now from service company as it looks like it needs a control panel. Worth trying yourself to fix the problem. Inexpensive part and easy to install. Also be sure to turn power off your oven to reset the control panel as this may fix the problem - try this first and also after installing new part - like rebooting a computer...

Had to remove oven from mounting cabinet to get to the back since the wire lenght to the conector was to short to come through the mounting hole.
Other than that the repair was straight forward. 4 screws to dismount the Oven from cabinet, 2 screws to remove Sensor and 3 srews to open the back of the oven once out in the open. New cable adapter that came with the new sensor was needed in my case.

Initially I made a false start by pulling out the stove, which was not necessary. Then dropped control panel by removing the several screws on the bottom of control panel. Removed the three connecting cables by freeing locking mechanisms. (The locks on the ribbon assembly are on both ends of the connector plug). Removal of circuit board then obvious. Installation of new circuit board quick and easy. All displays then worked OK. I added a fiberglass heat shield around the circuit board and time will tell if this worked or was a mistake;
Your troublshooting tips were very helpful.

I am curious how the chap who found capacitor C3 to be defective zeroed in on it without a test harness.

Ordered part on line, part came within few days well wrapped and protected, very simple repair removed two mounting screws and two lead wires to remove burnt element, replaced with new one, wire were re-connected and the mounting screws secured the new element in place, about 20 min job.

My husband removed the faceplate, removed the old clock and but new clock in, then he replaced faceplate. It was very easy.

I shut down power at the circuit breaker, removed the stove knobs, unscrewed the underneath screws of the front panel, pulled off the panel, and the electronic board/panel was there.

I unhooked the wires (3 sets), and used the socket to remove the electronic board from the front panel. I put it all back together. Very easy-- less than 15 minutes!

cut off power to stove & made sure it was OFF.
removed the few screws on the underside of front cover.
lift cover and un-screw the clock/display
I then removed the wire strip feeds (one has friction tabs that need to be lifted before you pull it.. it's the flat ribbon cable use the butter knife to lift the tabs...easy does it)
put the new clock in and reconect the wires. push the ribbon in and push the tabs.
All done and saved $160.00 bucks

First, DISCONNECT POWER or you can turn your panel into an arc welder. After that removed four screws that hold front panel in place and 2 screws that hold the display in place. disconnect ribbon cable and two other cables. Reverse operation for assembly.

For the self cleaning problem, replace door lock switch by pulling forward, use needle nose to remove & replace connector. Push into place. Very easy. Total 10 minutes for both jobs

Removed two screws, pulled out element and trnasfered over lead wires. Made sure power is off first. Easy to order, easy to replace.

Removed 8 screws and replaced the part (also did a good cleaning while we were in there)! Easy breezy!!!

The part came right away!
Removed six screws from above door, than pull knobs off and remove four screws that were under knobs.
Front panel pulls off. Remove display and put back together.
Peice of cake.
Wish all my projects were that easy!

Popped it in and now we have a well lighted control panel AND a night light for the kitchen. Just wish Jen air would design a longer lasting part!!!

Removed the oven from the wall. Removed back cover and unplugged sensor from the harness. Remove and replace sensor from inside the oven. Reconnect harness and reinstall back cover. Secure oven back into the wall.
