Re: Powers but no heat. Everything else functions
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.

sounds like its not on high power.. Some microwaves have a popcorn button..This is usually automatically a high setting.Try putting your water in then hit popcorn...If the water heats up faster then your power settings are set wrong. You just need to change them. Your not set on high power..
Sounds like you have a bad transformer. Magnatron should check less than 1 ohm (with wires unplugged). Diode should check resistance one way and open the other. Must have a proper diode checker for this. Check resistance on the capacitor (make sure it is discharged first). Resistance should come up then back to open, reverse and same thing if cap. is good. Check resistance on transformer windings.
The magnatron is likely to be the problem... though I have seen the fuses go , they usually follow the magnatron. If your unit is under 5 years old , the Mag is covered under warranty and all you need to do is contact GE at firstname.lastname@example.org
with the serial number of your unit and they will send you the replacement magnetron imediately and free of charge.
You are responsable to have the part installed , but there are videos on Utube that will walk you thru it no problem.
GE Will replace the magnetron for 9 years! Mine is a 2004 model with a one year warrently according to manual. HOWEVER they did say the magnatron was covered for nine years: call 888-239-6832. When I called they said thats all they get calls for and would send out in 3-5 days. NO CHARGE. I had to ask if there was coverage longer than a year on major parts and that's when they offered the info and I eventually was transferred to the right office. Saved $120 bucks on parts alone.
microwave ovens do not produce heat, they produce microwaves. the heat comes from whatever is excited by the microwaves. In your case i would bet that the magnatron (microwave tube) has become defective. If this oven is less than 5 years old, the magnatron may be under warranty. depending on the model it may be repaired at no cost to you. In the case of Kenmore (Sears) you would take the oven to their customer service dept and they will send it in for you for evauation. they will charge you $50.00 US this amount will be applied to the repair if you choose to have it fixed. If the Magnatron is bad and is under warranty, they will fix it, and return it to you along with a refund of you $50.00.
Sounds like the magnatron is shot. This is the main heart of the oven, the magnetron is what creats the Micro waves to heat the food. You might want to find out what it cost to get this replaced and then decide wheter the cost of fixing yours is greater than replacment of the oven. Christmas time is here and Microwave ovens are usually cheaper this time of year. This unit might have a fuse to the magnatron, you can remove the cover after you UNPLUG the machine and see if there are any replaceble fuses inside the cabinet. If this has any years and lots of use on it, I would simply repalce it. You get a warranty with a new oven and someplaces let you choice a replacement type warranty.
