Question about GE JVM1650 1000 Watts Microwave Oven

1 Answer

I have a JVM1860SF001 Microwave

The GE tech who came to inspect it says I need to replace the High Voltage Transformer and Motor Drive for the turntable. Can someone please give me instructions on how to do this? I ordered the parts but the labor GE is charging is high. Thanks in advance.

Drive for the turntable is quite easy to do, as for the transformer people have been killed trying to replace key components and if you seriously have no understanding of electrics and electronics then i'd pay the labour costs (its called high voltage for a reason) even with the oven off therecan be upto 3000v still within the oven and believe me it hurts when it shocks you, also with the transformer faulty it could have caused damage to the diode, mag and capacitor not always but sometimes and these are easier to check when changing hv transformer!!!!!

Microwave caught fire inside parts compartment.

Most likely causes are a shorted high voltage rectifier or burned-up high voltage transformer. Visual inspection should indicate which one. Be wary of the high voltage capacitor - some keep a charge of 4000 volts, or more, even when unit is unplugged.

Usually if the internal fuse had blown, the microwave part would stop working all together.

We have a JNM1851DBB GE Microware oven. The microwave is not generating any heat and the motor sound is much louder than normal.

The magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

How do you change the drive motor for the turntable in the jvm1860sf001 microhood

Very easy - remove the lower plate on the bottom where the fan and lights are. 3 screws across the front, two on each side. This plate will come down, and the motor will be right there on the bottom of the cavity directly below the turntable coupling.

Go to to find the motor.

Use a hair blow dryer to dry out the underside of the microwave. After you are convinced that it is dry you may operate it again.

That said, if it still is acting up read this:

When the microwave sounds okay, but there's no heat, one of the internal door switches, the high voltage circuitry, or the circuit board may have a problem. To resolve this problem, you need the assistance of a qualified appliance repair technician.

Wires to magnetron

It matters!

The wire from the high voltage transformer high voltage tap goes only to one side of the high voltage capacitor. No other wire is connected to that terminal of the high voltage capacitor.

The other side of the high voltage capacitor connects to the anode (A) of the high voltage diode and to the "FA" terminal of the magnetron.

The cathode (K) of the high voltage diode is connected to chassis ground.

The pair of wires connected to the secondary (thinner) winding of the high voltage transformer are the filament wires and are connected to the "F" and "FA" terminals of the magnetron.


There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

It has the overall wiring diagram and schematic.

Any Whirlpool Microwave Techs out there...Please help a fellow tech

hi mike,

I’m sorry to tell you this but; I wouldn't recommend using a different transformer, even if it's the same size, it could cause serious damage. The HV transformer should only be replaced with the exact replacement part.

Microwave problem

Magnatron is suspect. Need to put a voltmeter on the input (primary) side to the high-voltage transformer (big heavy iron thing in there) Should be getting 120Vac when it goes to cook cycle. Don't touch the other (high voltage) side of this transformer. If the power is there, you are looking at replacing either the magnatron or the high-voltage capacitor and diode. Its affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!

GE microwave

This is usually an indication that the magnetron has gone bad, or something in the high voltage network controls the magnetron. Any one of the following components could be at fault: 1. Magnetron 2. High Voltage Transformer 3. High Voltage Diode 4. Magnetron Thermal Cut-out 5. High Voltage Capacitor 6. Interconnecting wiring I do not advocate taking any voltage measurements inside the High Voltage section of a microwave since the voltages can be as much as 14,000 volts or higher. If you are savvy enough to attempt yourself, WITH THE MICROWAVE UNPLUGGED, you will need to disassemble the unit to get to the high voltage section and take resistance readings. The magnetron or diode are likely suspects. If the magnetron or the transformer are bad, the repair costs can meet or exceed the price of the oven. Let me know if you need further assistance.
