My microwave won't heat

The real clue here is strangely enough the table not turning.

All units have a switch in the side (usually the right side) of the cabinet--when door is opened it allows the unit to work but will not heat or the table (usually both) will not work.

It has to be got at from the inside of the unit--little plastic holder with the switch which looks like a leaf switch.

What I have seen several times (including a unit I own) is that from countless opening and closing the door the holder may break or even melt and the contacts on the switch no longer are in position to work when door is open.

The purpose of such a switch is simple---it prevents the unit from being used if the door is OPEN.

Not a hard or expensive repair

Whirlpool Microwave WMH 1163 XVS-0 How do you change the stovetop lightbulb?

Under the stove top should be a small panel the light emits from. One side of it should have a regular Phillips screw. Unscrew it and the panel should open. It is not hinged so you have to carefully work it open. Once open you should be able to see and then unscrew the bulb, I was able to find a replacement at Home Depot. The installed bulb was 40w, but I was only able to find a 25w replacement. Seems to work just fine though. Once replaced, just work the panel back on and screw back in.

Purchased new glass top stove Nov 3,2010. Now liquid stain is visible between the glass in the oven. Help

Clearly, you have a blown seal or gasket where the glass meets the perimeter of where it sits. This sounds like it is a manufacturer defect. If it "happened within 90 days of purchase," then, perhaps you were out of town and could not report it to the supplier or factory within 90 days to be covered under factory warranty -- wink wink -- I suggest that you be very sweet and in your best little girls voice ask retailer to kindly replace the stove. Otherwise, if purchase was via a credit card, you may have recourse there - ask your financial institution or go to the holder (ie visa, mc, discover also insure purchase - with limitation - see their policy) and set out that way as other methods of recourse may be available.

Best regards

The area between the glass on microwave oven door and the glass on then displays steams up while in use.

Be sure you always have the hood / vent fan on when using the microwave or the stove top.

Also, there may be a clogged filter. Check that.

Otherwise, I would be concerned that the internal cooling fan may not be working properly.

Dear Carluc

Right for this one, it is essential that you unplug the oven from the mains and leave it to dissipate any electrical current certainly for 6 hours. Once you have done this, you wil to get yourself a phillips head 6mm screwdiver and unfasten the screws on the back that hold the casing cover to the chassis. This will expose the enternal components, then all you simply need to do, is find the lightbulb, unclip this from the holder and then replace it with one of the same make and model. Fitting and re-assembly is as straightforward as it is taking the unit to bits.

go to and type in GE Microwave lightbulb........this will get you the details about the bulb, and use the same google search to get your service sheet/ disassembly guide. Easy as 1,2,3.

Hope this works for you and please contact me here if you need further assistance in this or any other matter that is of a technical nature.

Yours sincerely

Changing oven light

Some models use an tamper-resistant screw which can be removed with a specially-designed tool available from home improvement stores & appliance parts stores.

But some folks just use a hammer to tap and loosen the screw, then a "star", t-type, or small flathead screwdriver can be used to remove the screw.

Sometimes the screws are tough, so you may only be able to just bend the post slightly with a punch, then a small flat blade will "grab" enough to turn the screw. Pliers on the handle will help, too.

Another creative solution is to use a hacksaw or a Dremel tool to carefully cut a slot in the head so a flatblade will fit it.


We're happy to help and we appreciate your thoughtful rating of our answer.
