JVM1870SK03 General Electric Microwave - Instructions

The breaker was tripped but fuse was ok on testing. I kept the fuse for possible future repairs. To access door switches and fuse on this model JVM1850CF001, remove 2 phillips screws at top. Then slide the grill to the left (toward hinges) about 1 cm and it should easily come off forwardly. Remove phillips screw underneath grill attaching the main panel. Lift the panel 1 cm and it will easily come off forwardly - I let it hang by the electrical cords. Now you can see/discharge capacitor(s). Remove 2 star screws inside door to loosen/remove/access door switch frame. 3 switches are held in the frame by plastic tabs - one tab per switch. One is primary and 2 are secondary door switches. I removed each switch one at a time by lifting tab, pulled off the electrical connector and filed the male metal connection on each switch. I replaced the switch with a loose button (loose and didn't click as crisply compared to the other switches) with a new secondary door switch. It was the lower secondary switch. Worked like a charm after that.

Received part installed in less than one minute, easy fix alignment of part in shaft pressing down into position

Had to have my neighbor work on getting the broken grill out and then put the new one one. It definitely took some time. Was not user friendly.

Disconnect power to microwave. Remove plastic rotor attached to motor shaft. I had to pry up from underneath it with a screwdriver to break it loose. Cover surface below microwave as bottom cover screws are small and easily lost. Remove three front and two rear screws from bottom cover and it will swing down. Locate the drive motor on the cover, disconnect the power leads, remove one set screw and rotate the old motor off the cover. Reverse instructions to re-install new motor. Swing bottom cover back up and re-install the five small screws. I had a little trouble lining up the screw holes and it helped to use a finishing nail to align the holes in the cover with those in the microwave frame. Reinstall plastic rotor on motor shaft, reconnect power to microwave and test the turntable.

Kept the microwave in place( it is above the stove) 1 unplug the microwave 2unscrew the cover plate on the bottom3unplug connections,light and drive motor.4 unscrew drive motor replace with new drive motor,reverse the remaining process. Part took about 3-4 days to deliver,plan accordingly.

-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

Using a phillips screwdriver, remove 7 screws from the unerpanel of the Spacesaver Microwave. The panel will swing down from the rear edge hinge, exposing the lights and the stirrer motor. Remove the electrical connector and two screws holding the motor in place and remove the motor. The stirrer inside the oven can then be removed if desired. Install the new motor in reverse order. Note rotate the stirrer inside the oven to align the motor shaft to facilitate assembly.

This microwave has two separate spring-loaded latch pawls. To get the broken latch pawl off and install the new one you first take off the rectangular plastic trim piece from the inside of the door to expose the pawls. There is a pin that secures the pawl in place. To get the pin out I had to carefully drill a regular hole bigger than the pin with the Dremel tool at the edge of the plastic door piece. I then could extract the pin with a small screwdriver or twizzers. The old pin and spring will come out and you reverse the procedure to install pawl and pin and connect spring. Then reinstall trim piece. I put a small piece of black electricians tape over the hole I made in the door edge. It doesn't show when door is closed and it blends well with the black plastic edge. Test to make sure microwave works and mine did after some carefully fitting of the trim piece.

Removed the cover, 6 screws and then the motor, 2 screws. Unpluged the old motor and just reversed the process.

Nice. Half dozen screws drops the bottom, 2 screws on the motor, pop in the new, reassemble and throw in the popcorn. (Was skeptical. Have replaced quite a few of these little motors in data centers. Common part in high-speed printers. Never saw one fail like this but your feedback convinced me otherwise.)

placed plastic ring under glass rotating plate in microwave

The Glass cooking tray was very noisy. This was verified by turning off the tray rotation.

1. Removed the two metal filters.
2. Removed the screws holding the bottom cover of the microwave. 6 or 7 I believe.
3. Removed the two screws holding the drive motor in place.
4. Started the microwave with the motor hanging down to to verify it was defective. I could hear the motor rotating and making noise.
5. Replaced the motor, bottom cover, & filters in reverse order.
6. Tested, Works fine!

Remove the 8 screws in the bottom pan covering the bottom, unpluged the lights and motor plug-ins, slid or pulled the pan forward or to me and removed pan. prized the triange piece which fit into the glass tray to turn it to remove it. removed the two screws which held the motor in place. presto, got the model # off the inside panel and ordered the part on the compiiter, \. arrived in 5 days.
P.S. cleaned everything while I had it apart, toke longer than chancing the part.

Dropped the bottom of the microwave,removed the two screws holding the motor in, disconnected the electric wires, reversed the procedure and it worked like new!

I removed the screws (7) around perimeter of bottom. Don't remove the middle screw as it holds some gizmo in place. Dropped down hinged bottom. Removed motor (2 screws and a plug) matched to picture on website and ordered.

2 days later, part arrived, installed, good to go.
