JVM1665DN2WW General Electric Microwave - Instructions

Required removing the old unit and disconnecting the exhaust ductwork and drilling new holes for attachment to the cabinet

Unplug the microwave. Remove the Philips head and safety Torx head screws along the bottom of the sides and rear of the microwave which hold the black cover on. Lift the cover up at the rear and slide it backwards to disengage the tabs on the front top. Remove the cover. Discharge the capacitor by shorting the terminals to each other and then ground. Do this with a well insulated object and be aware there may be a pop when you do this. Keep hands, etc. on the insulated part of the object (screwdriver handle, etc). There's a lot of stored energy in that capacitor. I'd advise first checking the diode to make sure its not bad. Replace it if it is. The Magnatron is held in with a couple of screws on the top and sides. Unplug the connector and remove the screws. Remove the Magnatron. Installation is the reverse of removal.

DISCONNECT THE POWER CORD and discharge the capacitor
Leave unplugged overnight
Remove vent grille by removing the 2 philips screws
Remove the LED panel by removing 1 phillips screw
Disconnect all connectors that plug into back of the LED board completely
Remove the wires from the switches (3) at the inside edge of the microwave door
Gently remove each switch housing and test all three switches for continuity
Carefully replace non-functioning switches and reassemble the panel
GOOD LUCK

Remove the ice bin.
Turn the ice maker selection to "OFF"
Use small flat blade screwdriver to open the plastic ears on the electic plug in connectiion
Use #2 Phillips screwdriver to remove the screw on the front left side of the ice maker
Pull the ice maker forward until free of the two studs in the left side rear of the freezer wall
Check to see if the supplied water chute is the correct size for your application, if not remove the water chute from the old ice maker and place it on the new one.
Place the new ice maker in the freezer connecting the slots on the left read with the studs on the left wall
NOTE; IF THE ICE MAKER DOES NOT APPEAR TO BE LEVEL HORIZONTALLY REMOVE IT AND CAREFULLY REINSTALL IT TO ACHIEVE LEVEL
NOTE: ENSURE THE WATER DELIVERY TUBE RESTS IN THE RECEIVER TRAY
Reconnect the electrical plug ( needle nose pliers may be helpful in aligning the male plug with the female plug)
Move the selector from "OFF" to "ON"
Replace the ice bin and close the freezer door

I verified I had 120 volts going into transformer when the microwave was supposed to be running. The capacitor and HV diode both tested good. Be sure to discharge the capacitor before working in this area. This isolated trouble to either the transformer or magnetron. The windings of the transformer measured good. So ordered a magnetron. It was very easy to swap. There were 4 screws and one connector. This fixed our microwave.

Part just snapped into place and wires were reattached.

Unscrewed the control panel (2 screws), lift up and let hang, with a plan screwdriver open bracket holding the switch, unplug 2 wires, replace with new switch, plug in the 2 wires, push switch back into bracket. Then slide on the control panel, put the 2 screws back. Easy fix.

Opened the light cover. Removed the old light bulb using a light tug on the old bulb, lined up the new bulb and pushed gently into the socket.
Turned the power back on and the microwave is good to go.

Went on Youtube and pulled up how to fix a microwave.

remov cover to check voltage and found problem at the interlock switch ohm the switch and found it was open replace both switches it work fine now

First I had to accept the fact that the unit was designed to keep non-professional people from doing any repairs. The switch was installed in such a manner that I had to break the mounting to remove the switch, then drill a hole in the mounting to secure the new switch in place.

Used a Motor cycle Jack to remove both unites combined. Removed side panels exposing internal working parts. Removed nonworking Magnetron and replaced it with new Magnetron. The process was completed in about 1 hour.

-unplug
-remove top and front covers
-unplug wire connectors from heating assembly
-remove heating assembly from metal stand and push out of the way
-remove metal stand from dry
-pull out heating assembly
-install new one in reserve order

Googled problem, removed diode, checked with meter and it was open, ordered new diode, checked new diode and it read open, installed. Any way, it didn't work. Went and bought new microwave!!

unplugged power
removed main black cover.
located part WB24X10047 and replaced
