Question about GE JVM1860 Microwave Oven
My spacemaker micro wave has suddenly started making a crunching noise whenever it is heating up food. No noise if fan on only, and I have tried without the turntable turning. It is 4 yrs old and the fodd heats up as usual. It is just the darn noise its making. Any ideas? thanks
Rotu is right - it certainly could be crud on the waveguide vcover or waveguide. If not, it might very well be be a bad magnetron. My understanding is that GE had a run of bad magnetrons and/or other problems in the high voltage section, but I don't know if they publicly acknowledged it. If it's not a dirty waveguide problem, I would contact GE or an authorized servicer. If you don't have a manual, you can download it here: http://www.geappliances.com/service_and_support/literature/

Could the noise you are hearing be maybe an electical sparking/arcing noise? It could be that the wave guide cover inside the micromave cavity is dirty, and needs to be cleaned. If it is not, then it could be a bad magnetron crackling and going bad. If this is the case, it is likely going to damage the waveguide and render the microwave unrepairable. I wouldn't use it until you have it checked out or take it apart and check it out yourself. Hope this helps.

You have burned out the magnatron (heating element) which is common on GE microwaves. most service companies will charge about 200-250 to replace it

If everything works, but the microwave oven does not heat, this is commonly caused by a failed magnetron. The magnetron is essentially, the heart of the oven. This is what produces the RF energy that heats your food.
Here's what you need to determine whether or not its worth fixing:
1. You will need to uninstall the oven from over the range in order to replace the part (you will need to do this anyway, if you decide to buy a replacement oven).
2. You will need to ensure the oven is UNPLUGGED before servicing anything inside the cabinet. You will need to remove the exterior case in order to access the magnetron. There are several websites that you can use that illustrate how the oven is assembled:
searspartsdirect.com pcappliancerepair.com appliancepartspros.com
If you've never repaired an appliance on your own before, a microwave oven is usually not a recommended appliance to start with. Some models can be rather involved in taking apart.
3, The magnetron replacement part number for the model you have listed is WB27X10305. The average cost is about $80. NOTE: I found the part listed for the best price at appliancepartspros.com at a cost of $76.
You need to decide whether or not $80 and the amount of labor involved is worth the effort as opposed to replacing the entire oven at a higher cost and less labor (other than the installation). Review the parts illustrations at the recommended websites to see if this is something that you may be able easily take apart and reassemble.
If you have any questions, please post back and let me know. I hope you find this information helpful
CAUTION: DO NOT operate a microwave oven with the exterior cover off. The voltage inside the High Voltage network where the magnetron is installed can exceed 3,000 volts.
