Question about GE JES1142SJ Microwave Oven

1 Answer

Display fully lit (all characters) @ plug in but unit not running

I bought this unit 2nd hand, although it does not appear to have been used. (Perhaps this is why).

As I plugged in the unit, the full display lit up, showing all characters (resembling 8,8,8,8,), but will not accept any commands on the touchpad. I tried plugging and unplugging, looking for a reset, etc., but found nothing at first glance.

Can anyone please help me?

    Thanks for the insight. I still have one day left that I can return it for store credit, at least! Good timing, and thanks again!

I'd say you have a bad keypad, or possibly a problem on the control board.

But with the cost of a comparable unit ($85 at Wal-Mart), it may not be economical to repair.

It would run $39.95 if we just repair the board, or about $50 if you replace the keypad frame assembly yourself.

Spending a little more would get you a new oven with a warranty.

Microwave will not run a cook cycle. Touchpad functions until door is opened or start button is pressed. When door is opened display goes dark. When door shuts display lights all characters and then says...


BEFORE DOING ANYTHING DISCONNECT OVEN FROM POWER. I do NOT recommend doing repair by yourself, if you NOT are really very familiar with electric repair, or have at least basic training in electric device repair and maintenance.
"When door is opened display goes dark. When door shuts display lights all characters and then says "touch clock"."
Obviously, by opening door, oven gets disconnected form power line.
This is mostly caused by loose connections on wiring socket, and can be anywhere inside. Check security micro switch on door latch. This switch normally disables only running the oven when door is open, for security reasons. In your case, it seems that opening door disconnects oven from input power. Sometimes the switch is loose, or wires are not firmly pushed in the socket. If the power line wiring is loose, and by opening door looses contact with socket, it can touch metal housing inside, cause short, electric shock, serious even mortal injury and fire. This is dangerous high voltage switch, and to access it one must open oven from the back and take off the cover. I do not recommend doing it by your self.
Rem: Replacement micro switch is couple dollars.

The microwave runs but does not heat the food. Unit was bought sometime in 2004 or 2005. (When I press the MICRO control pad, a number 16 with underscore colored red appears near the upper left hand of...


Whirlpool typically supplies a service sheet with schematics for servicing the oven. This is normally located in the compartment where the micro control board is and requires you to removes it to acess it. These service sheets have fault codes and causes on them.

If you are inexperienced at working with electronics I suggest replacing the unit as the cost to have the unit serviced will likely exceed the cost of a new unit.

Good Luck

Display numbers/words disappear


There are two options for this model:

- You can order an exclusive modified display control unit (#CU440) with proprietary upgrades for $115, then if you return your defective control unit in repairable, good cosmetic condition, you get a core refund of $30. It comes with a one-year guarantee. Details are here.

- Or your existing control unit can be repaired for $39.95 in most cases, also with a full one year guarantee. Details are here.

My KHHS179LSS-3 will not let you control microwave from touch screen un pluged unit plug back in touch error high fail low fail appears on screen


I was afraid I needed to replace the microcomputer when my KHHS179L touchpad was unresponsive. I was able to use the ADD A MINUTE feature, so I knew the unit worked. There had been a power outage of less than a minute to my home recently (I was unaware of this until I asked the kids if they had done anything to the microwave). I popped around on fixya.com and really didn't find an easy solution-my favorites. I loaded kitchenaid.com and found the answer in the FAQ's. Although the control lock out icon was NOT LIT-apparently, that power surge locked my controls. By holding the stop button for 5 seconds once and then aagain a second time, miraculously, my touchpad was restored> HOORAY!

Display not lit up


Seems like the display panel went bad. You can check for sure by unplagging the unit for 45 seconds and plugging it back in. If still no display order a new display panel.

Total power loss during use


Check the voltage on the outlet,make sure it is 115v -- 122volts max, any less will cause it shut off, make sure the polarity off the outlet is correct and it is grounded,check all of your wiring connections, if all this is ok replace unit with a different unit or different supplier of unit

Microwave not working


The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for maybe an hour. Then let us know if the hard reset does not fix it.

Otherwise, your controller or keypad may have moisture on it.

GE Profile Advantium Wall Oven 240 volts 950 Watts


How long does it run before it fails? Does it look like the display is getting scrambled characters? I'm leaning toward a bad magnetron, but it may be more or less than that. If you can give more details and especially the actual full model number (as opposed to the model name Advantium 120) that would help. Thanks!
