GE Microwave JVM1190, fan does not turn and fuse is arcing

We noticed a burning smell coming from the top vent panel this morning. I looked inside the upper vent and could see wires arching. I removed the upper vent panel to expose the wires. I turnd the unit on a could see that the fan blade was not turning and the arching was coming from the rear contact of where the fuse was located. The red belt on the fan blade was not turning and was wondering if this was putting a load on fan motor and perhaps causing the fuse to arch. Any ideas how I can repair this problem.

    Purchased August 2000, GE Profile Performance. The red belt is a drive belt about 12" long, it comes off motor pulley located top middle and drives a black fan located top right. The drive belt had had come off the motor pulley and lodged itself under the pulley preventing the drive motor shaft to turn freely. I suspect that due to the drive motor not being able to turn it was putting an unnecessary load on the internal fuse. It was the fuse that was arcing against the rear fuse housing. I freed the red drive belt up and fitted it back on the drive pulley. The motor now spins freely turning the drive belt and engaging the fan to turn. There is no more arcing of the fuse against the housing. Howver there is a charred smell still present from the arcing hot spot on the circuit board. I have ordered a new drive belt as the old one was stretched which i am sure caused it to come off of the drive pulley. I have also ordered a new fuse. These parts are due in tomorrow. I am able to replace these parts and I hope that fixes my problems. Thanks for any further help you can provide.

    I'll give the isopropyl alcohol a shot and hope the new belt and fuses gives us another 8 years of use!! Thanks so much for your comments and support.

    Still some serious arcing coming from the rear of the internal fuse housing connector. Any idea what might be causing this to happen. I went to use the microwave last night and didn't like what I saw and smelt. The drive motor and drive belt were working fine.

    How difficult is it to change the motor? Any idea what the motor cost would be and a ballpark on the labor cost to replace it?

    Here are a couple of pictures attached showing the burned hot spot on the circuit board underneath the rear fuse stand-off. I am concernd about potential fire. Do you think i should replace the entire board or can it be repaired

If your motor runs freely and normally, I would not worry about the charred or burn smell as that will be there for a while. You can however to lessen that smell is to power everthing off and unplug the ac cord and use isopropyl alcohol with a cleaning brush like they use to clean circuit boards and clean the area thoroughly where the hot spot was. In that way in the future if you have a problem in that same area that persists after your initial fix then you can pin point it to the particular spot if it is a component that for instance drive the motor or is part of that circuitry. However, I do not think you will have anymore problems once you change the belt.

    It is odd that there is still arcing without blowing the fuse. Since the motor runs from the ac coming into the unit after it is switched on by the logic circuits, it could still be your motor causing that arcing as it may have overheated and melted some of the windings stemming from your original problem. That is a very distinct smell to be sure and smells like something is on fire, but it smells like the melted insulation of the motor windings. That is why I believe it is not blowing the fuse since the motor is still functioning to some degree as opposed to being shorted out completely. The ac coming into the microwave is hardwired in and it stays that way until it reaches the control panel where it is broken down into lower dc voltages to operate the logic. If you have like some alligator clips insulated, I would clip the side of the fuse off the connector that is arcing and clip the other side to the wire coming to that connector (this is of course after you remove the wire from the connector itself) In other words you are going to bridge over the arcing part of the problem with what you know to be a good mechanical connection between the wire coming into the fuse connector and the fuse itself. DO THIS WITH THE POWER DISCONNECTED!! Once you have done that turn the power back on and operate as normal. If it arcs at the point where the alligator clips were connected, then I would seriously suspect the motor. However, try that first then let me know I will be glad to help you through this.

GE Microwave is arcing inside


Quite often this is due to grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover.

The waveguide cover is usually about the size of a playing card and often held in place by a plastic rivet.

In some models it is the plastic ceiling.

It can be fragile, and the metal edges of the oven behind it can be sharp, so be careful!

The cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner.

If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean and dried thoroughly.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

If your waveguide cover is burned, it will need to be replaced.

If you need more specific help, please reply back with your brand and full model number.

JVM1190 wont cook


You have a blown actuator. This is the device that creates the microwaves that cook the food. The cost of one of these will be as much as a new unit.

GE Spacesaver JVM 1870 carousel doesn't turn, doesn't heat


We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan operation and other operations, too. The lights and fan can be inoperable or stuck on too.

Details of our service and critical safety information and disassembly information is at our site, and our link is at our listing here on FixYa.
