Microwave oven not heating up


The problem could be the magnetron, "heart of the microwave" the inverter board, "if 7 years old or less" and possibly the keypad control board.

Hi, I have a GE JES1334 1100 Watts Microwave Oven, it can be power on, but doesn't heat, should I change any part to get it back to work? Thanks!


Hello, W/D here.
There are many variations of your model. Check the fuse first.That's the most common failure, and the cheapest to fix.
I checked the price of magnetrons and, if that is what is wrong with yours (which it sounds like), the cost of the magnetron is more to replace than the price of a new microwave. ($162 vs. $115), plus shipping if you bought the part on-line (I checked Appliancepartspros.com), and add in labor if you have someone else do the work. Your best bet is to take it somewhere and get a free estimate for repair, and decide from there. It may not be the magnetron, but it's impossible for me to tell from here.
Best regards, --W/D--

What is watts for goldstar MA 1280M Microwave and if it is over 1100 watts cani i adjust it down


You can set it to different levels. It is doubtfull the magnetron will deliver more than 750 Watts as that is about all they can produce singley. Commercial ovens use at least two magnetrons.
Most specs on microwave ovens quote the power drawn not power produced.
I hope that helps.

The microwave will not heat up any food


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 and the diodes), 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.

Its runs but no heat.


It is usually the magnetron tube that fails which then blows an inner-cabinet fuse. The world seems full of bad Asian made magnetrons that fail prematurely due to air infiltrated internal vacuums from leaking metal to glass seals. It will probably cost more in parts and labor to repair than a new unit. A well made magnetron should gradually lose output power over time (years), not just quit. Hope this helps!

JES1139 is not working properly. The round table is rotating but the food is not getting heated.What is the problem?


HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

Kenmore model 80604 microwave will not heat


Sounds like the magnetron has failed. This is the component that produces the microwave that heats the food. The cost of the magnetron is about 95% of the cost of a microwave . Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing. There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

GE XL1800 1100 Watts Microwave Spacemaker


Yes, it could be the Magnetron. If the unit is out of warranty, you can try to remove the rear cover (make sure unit is unplugged) and see if there is a blown fuse in the section that powers the Magetron. They are not too difficult to replace. MCM Electronics sells them and you can call them with your model and they can find a replacement for you will be able to see how much it will cost.
