Question about GE JVM1660 Microwave Oven
I have a GE JVM1660 003 over the range microwave, manufactured in March of 2000. It was making a humming noise and blew a circuit breaker. I replaced the magnetron, diode and stirrer, but it has the same symptoms. I can't say for sure if it is heating or not... it blows the breaker after running for 15 sec or so. Could it be a bad transformer?

Since power = voltage X current, 1.58kW / 120VAC = 13.166A
So this unit should be fine on a 15A breaker unless the breaker is bad, the wiring or a connection is loose somewhere between the breaker and the microwave, or the microwave's magnetron or high voltage transformer are failing and drawing extra current.
Microwaves should really be on the own separate breaker if at all possible. Plus, the more a breaker trips, the more work out it gets.
Have you measured the voltage at the outlet? If that's off, current and power will be affected. It should be about 110-125VAC.
A good power test for outlet and wiring integrity is a toaster, toaster oven, or hair dryer rated at about 1500 watts.
If it doesn't run and heat steadily, then there may be a problem with the house wiring or breaker.
If it passes this test, the problem is likely in the microwave.
We're happy to help and we appreciate your thoughtful rating of our answer.

The problem may not have anything to do with the magnetron.
It is a device that uses DC for operation and to supply that, there is one or more heavy diodes that are more likely to fail first.
Have also seen the transformers fail occasionally too.
Frankly, it may be time to dispose of it since you will likely be billed for the repair if the magnetron is not at fault and once they have it, you don't know if the truth is being told or not.
Another possibility is a circuit breaker on its way to the grave.
If you care to go to the trouble, you might shut down the main breaker in the breaker box, swap the tripping breaker with another of the same rating and try the microwave one more time.
The surge current the microwave draws is probably a good bit higher than the hair dryer and might be enough to trip an aged breaker.

SOURCE: Microwave Upper Stirrer Motor
What up, Roller?
The straight up answer to your question is "Yes, you can continue using the oven without the stirrer motor". Here's the thing, though... the stuff you put in it won't heat evenly. I'm talkin' about big stuff; turkey, ham... stuff like that. And if you've utilized the defrost function in the past, you can forget about that now. But if you use it to heat up a dinner plate or a cup of coffee, you're good to go.
Another thing. You're motor is not the problem, it the coupler that connects to the motor shaft that has given out on you. That's the thing that connects to the motor shaft. You can see it, by lifting the glass outta your MW... see that little plastic drive gear there? It has three spokes on it. That's the gremlin in the machine.
The part number for it is WB06X10144. You can call a local appliance parts place or you can get one online (<---just type in the part number to a search engine).
Simple to replace... pull the old one out and slide the new one into place. See? Easy! Oh yeah, then you have to plug the motor back in, but hey! You already know how to do that! Cool!
Don't forget to rate my solution, OK? Show me some FixYa love, Roller!

were you able to replace the magnetron? Did it fix your problem? I have the same issue, and so I wanted to find out from someone who possibly tried it firsthand!
