Won't heat Hi, I have a GE XL1400, model # JVM1450WA001, Serial # VT912779S microwave that doesn't warm up anything. All the controls seen to be working ok, it just stop warming anything. One of the last times it was used I heard a popping noise behind the control panel, it hasn't worked since. Any help would be appreciated. Alan

    I also have a Spacemaker model JVM 1650wB004, serial # HZ969634S manufactured in May 2000. When you put the microwave on, it makes a loud buzzing noise, the controls work but it does not heat anything up. I checked the breaker and outlet and they are both working. Is this also a magnatron problem? If so, it seems that microwaves should last longer than 8 years especially this type which sits above my oven/stove and was not cheap to buy plus I had to pay to have it installed!

The Microwave's "Magnetron" is what heats things up. This is true for all Microwave's. The magnetron is normally on the left and sends excited electrons across the interior. Those electrons bounce around inside until their energy is spent.These excited electron 'waves' are slightly larger than the hole openings in the front door glass panel black grid. Usually, when a magnetron goes you would see and hear some popping and witness some arcing inside the interior. However, you may not have been nearby when this happened. Since you heard popping behind the control panel, you probably have electronic failure in the control panel and that failure may have been precipitated by the magnetron or not. In any case, it is very dangerous to disassemble a Microwave and access the magnetron unless you are trained and have been qualified to do this.

With the cost of Microwaves having stabilized and also being quite low compared to 20 years ago, I would take it to a warranty service provider in your area that also sells them, such as Home Depot for example. That way, if it is too costly to repair compared to a replacement cost you can shop for a new one and may even get a discount should you ask them to give you one.

I have a ge spacemaker XL1400 model # JMV1440WD. Everything works fine but it will not heat anything. Any suggestions?

The magnetron (the part that heats the food) may be bad or the circuitry to the magnetron may have burned out. Basically my advice is that if you have no electrical expertise, it isn't worth fixing. The magnetron if bad, costs almost as much as a new microwave. If you open it up (make sure it has been unplugged for a few hours and don't seen any obvious burnt parts (including a fuse), then most likely the magnetron is done and a new microwave is the way to go.

Let me know how this works out for you.

GE Spacemaker Microwave XL1400- No heat

The problem could be anything from a defective control circuit board or a burned out magnetron tube. Either fix is quite expensive and you'll have to evaluate whether you think the repair is worth the cost vs buying a new microwave.

Bear in mind that a fixed microwave is still a used microwave. So to get an apples-to-apples comparison you have to ask yourself, would I pay $XXX (substitute XXX's with actual repair cost) for my used microwave?
