The reading would be almost zero.It is anywhere between 2 to 4 ohms for heater coils. and 3 to 8
ohms for transformer coils. This should solve your problem. E-mail to us for your comments.

I have a GE Spacemaker Over-The-Range Microwave Model #JVM1533WD002 that has worked perfectly for 10 years. Now everything still works, except it doesn't heat the food. Where is the fuse located and how...

A common symptom of a failed magnetron is a failure to heat with everything else (magnetron fan, stirrer, timer, etc.) working fine. Check the GE manufacture date for the unit on its nameplate to determine the age of the magnetron. For GE models of the past, magnetrons had a 10 year parts replacement warranty. Magnetrons can be expensive, so you need to weigh all your options, i.e., repair versus replacement, before you commit to one solution.

Runs but doesn't heat replaced two fuses and magnetron still doesn't heat

Here is your free answer in under 10 minutes ...

You have a faulty door safety interlock switch. I wish you would have searched your problem here before you spent all that money on the magnetron. I have answered this question dozens of times here at this site.

When the oven runs but doesn't heat, more often than not it is nothing more than a faulty micro switch in the door latch system. When the switch doesn't work properly, the oven doesn't know the door is closed. If the door isn't closed, the oven will not energize the magnetron. Capacitors and magnetrons are **** and expensive answers but these items are extremely tough. It is the tiny contacts in the micro switch that can not stand the repeated abuse given them when we (read me in that number too) open the oven while it is energized causing a repeated flash across the contacts.

Thanks for your question @

Went to use and everything works except it does not heat

No heat means that the magnetron circuit has failed. It is the part the generates the microwaves that heat the food. Magnetrons replacement cost are high, usually as much as a new oven so it is rarely cost effective to repair. Sorry.

Hi, I have a SHARP Microwave Model R398F. Its less than a year old. The display and timer work fine but does not heat up. Can you please let me know what the problem could be. Thanks Js

If the operation is otherwise normal with the exception of heating food, common causes include; (to diagnose requires discharging of the HV capacitor) if you are inexperienced with working with HV I suggest seeking professional help.

Open thermal protectors or thermal fuses.

Open HV Diode.

Open HV capacitor

Open magnetron filament

Open winding in HV transformer

Defective HV relay

Shorted HV diode

Short or other fault in the magnetron

Short in certain portions of the HV wiring

Replacement Magnetrons (the most likely cause if not charring or defective components are found when troublshooting the small parts, can typically be had for around $45.00 just do a web search for your model number.

Good Luck

Panasonic 1200 watt microwave oven model:NN-S561BF,year:May 2001.When trying to heat foods the unit runs for 5-10 seconds then stops,I don't sense any heat.Anyone have any common repair tips? as I have...

Wow you must have been a TV repair tech too. Salute!! They have gotten more safisticated but some things never change. The magnetrons are real reliable. If the unit runs for 5 to 10 seconds it sounds like a control issue. The only other possible problem could be a bad HV diode. The new units have the safistication to know when the magnetron is not working and would shut down. Certainly an easy and cheap fix. You seem to have the expertise to explore this. Let me know how it works out or if you need more info. Thanks for using FixYa.

Microwave turns but doesnt heat?

The heat in a microwave is generated by a part called a Magnetron. If the mag is gone, and the unit is older, it's not worth the cost of the repair. Check you manual, some magnetrons have anywhere from a 3-5year warranty.

Maytag Microwave model#MMV5186AA

Typically, no heating of food, indicates a bad Magnetron (tube) or associated components. The oven can be repaired. Magnetrons are not hard to replace and can be ordered online through MCM electronics www.mcmelectronics .

However, due to the dangers of high-voltage within the unit, I would recommend taking the unit to a repair center.

Look in the manual to see what the warranty says. See if there is any information regarding the magnetron or parts. You may be able to get it repaired for free parts, less labor.

Please let me know if I can be of further assistance to you.

Good Luck,

- Jim

Oven runs but does not heat

This is going to be either the high-voltage transformer, the magnetron, or the high-voltage diode. Magnetrons are the mosty common failure in these, and there is a campaign underway to replace "underperforming" magnetrons. To see if yours is one of these, visit:
