Question about Microwave Ovens

Need to replace Thermostat or Thermal fuse

I have searched everywhere and can't seem to find a definitive location for the thermal fuse. I took off the control panel and nothing seemed to match the pictures or descriptions I have seen. I even looked at the Sears parts diagram and could not find the part labeled.

GE model # JVM2070CH001

Any help you can give me to locate the fuse and thermostat would be much appreciated.

THANKS!!

    Thank you so much for your speedy response!

    I need to replace the TCOs because there was a fire in my microwave and now it will not start. Everything looks perfectly fine and it seems the general consensus is that these sensors need to be replaced.

    I suspect the one most likely to be opened is the one in the cavity (#59). I believe I have spotted the one on the "bottom"and the one in the "hood" thanks to your help, but i'm not sure how to access that third one at the top left of the microwave.

    Is there any easy way to access this? or do I have to take the whole microwave down and tear it apart ? :/ I know it varies with makes/models but wanted to know if there is an easier way.

    also, do you think that all the TCOs are bad now?

    Sorry for all the questions!!! Thanks again for all your help.

GE calls them TCOs or thermal cutouts.

There are three in this model and they can all be ordered here.

The reference numbers relate to the drawing here.

REF# PART# DESC

111 WB27X1127 TCO -BOTTOM

59 WB27X10195 TCO -CAVITY

104 WB27X10194 TCO - HOOD

101 WB27X10388 FUSE

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 & testing. It usually shows relative component layout.

    On a built-in, you have to take it down from the wall and then take the outer cover off.

    It's much easier if you have the installation instructions. If you don't still have yours, you can download GE owner's manuals and installation instructions here.

    I recommend two people to take it down due to the weight and awkwardness. It's safer that way.

    The cavity TCO / flame sensor / heat sensor will be on the left top of the chassis.

    Again, the mini-manual usually shows relative component layout.

The part number of the Thermal Fuse? Can anyone confirm that it is WB27X709?


GE WB27X709 - Vent Thermostat. The thermostat opens and closes if it gets too hot in the microwave to run the vent fan.

Yesterday, my sharp carousel r-1460 went dead. I took apart the front keypad and replaced the 20amp fuse behind it. the microwave light and fan work.But, when I start microwave to cook something, pop! fuse...


If the 20A fuse is blowing, it is often the high voltage transformer or magnetron. If this is the case, and the microwave is not under warranty, replace it. Residential microwaves are generally considered disposable. Parts and labor are just too expensive. A magntron or transformer can cost more that half the cost of a new microwave.

Goldstar mv1502w has no power.Not even on display.


You can find the service manual here.

(Also, the owner's manual is here in case you want it)

I would suspect the magnetron thermal fuse / thermal cutout / thermostat (depending on which it has) or the oven cavity thermal fuse / thermal cutout / thermostat (depending on which it has).

To access some components, namely the oven cavity thermal device, you will need to remove the oven form the wall, in which case the installation instructions are very handy.

You can order L.G. parts from Encompass. Or you can call them toll-free at 866-779-5835.

Overheated microwave


Hopefully the magnetron thermal cutout or thermostat protected the magnetron from destruction!

It may be the fuse, which is usually located behind the grille or on the floor of the oven behind the control panel or between the door switches.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If you or someone you know decide to look into it, we have critical safety information and disassembly information 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 & testing.

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

Fire in microwave


Seems like I've answered this one, too.

Two 20A fuses?? In a recent GE?

The interlock is a door switch, not a thermostat or thermal fuse. A thermostat will reset (unless defective) but thermal cutouts and thermal fuses are one-time devices.

GE Spacemaker 2.0 Microwave just died!


If you're getting power at the outlet, the most common problems causing a "dead" condition are a bad thermostat (or thermal cutout / thermal fuse) on or near the magnetron, a blown internal fuse, or a problem on the control circuit board. I would suspect the thermal cutout / thermal fuse in this case. You can find helpful exploded view diagrams and order parts by entering your model number here: http://tinyurl.com/gv383 If it seems to be a problem on your control board, we repair these for $39.95 nationwide in most cases. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk If you need more help, feel free to follow up here, but please include your model number (e.g. JVM1190, etc.) I appreciate your thoughtful rating of my answer.
