Question about Microwave Ovens

1 Answer

GE Model JES1334WD. Having problems with entire control panel going blank and locking up. Can get it started again after clearing panel and resetting clock. Tried to heat for 1 or 2 minutes but it runs for 6 or 7 seconds and then stops. The panel goes to all 8888s lit up and locked up. Any ideas ?? Occasional lucky time will run for a minute or so but this is not consistant.

Sadly, we hear of this over and over.

This is due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.

It may also need a new high-voltage diode and stirrer, and the cavity may be affected.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

They may send you a replacement magnetron. GE Customer Service is here.

Ge microwave jvm1740 start and clear/off button not working


Sounds like a bad keypad. You will need the full model number off the microwave to look up the correct control panel part number. Sometimes these type of parts can be really expensive & it may make more sense to replace the microwave depending on the age and condition.

See this FixYa solution. even if your model number is different.

My control panel has locked and I can't unlock it.


If this is a GE Spacemaker model, you can lock or unlock the controls of the oven by pressing and holding the CLEAR/OFF button for 3 to 5 seconds. If this is not a GE Spacemaker, please post back with your correct MODEL NUMBER. I hope this information helps you.

GE countertop microwave shows "F3" on display, won't work


F3 on a GE means you have a shorted membrane keypad.

There are two ways to fix this model, either replace the membrane keypad which is a lot of work (handy guide with pictures) or to replace the complete controller.

It's probably not going to be economical even to repair it yourself if you or a friend want to. It depends on the model:

JES1334WD001
JES1334WD01
JES1334WD02
JES1334WD03
JES1334WD04

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

I looked up parts prices for the -02 verison.

ref # 38 part number WB27X10554 membrane keypad $69.71 here (compared to $112.50 direct from GE!)

ref # 42 part number WB07X11076 complete controller assembly $131.01 here (compared to $196.25 direct from GE!)

How do I unlock the control panel


If this is a GE Advantium series microwave, the control panel can be locked to prevent children from manipulating the controls. To lock or unlock, press and hold the CLEAR/OFF button for 5 seconds. These instructions are included on page 36 of the owner's manual listed here:

Control locked


If yours is a GE JVM1640 or similar GE model, here's what the owner's manual says:

To lock or unlock the
controls, press and hold
CLEAR/OFF for about
three seconds. When the
control panel is locked,
an “L” will be displayed
to the extreme right.

GE Microwave JES1334WD Code -P3-


Are you sure it's not F3? That would be a shorted keypad ("membrane panel").

That's usually not too big a job for a DIYer, but if you'd like, we can do that for $39.95 plus parts.

If you or someone you know decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

One good test is (with power unplugged) to unplug the keypad, then plug the oven back in and see if the error code shows up.

You can find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

There should also be a very helpful "mini-manual" hidden inside the unit behind the control panel. It's very helpful when troubleshooting.
