JVM1870WFC03 General Electric Microwave - Instructions

Manually with no tools

First I unscrewed the screws that were holding the panel underneath. Then I removed the panel and removed the screws that held the turntable motor in place. Then replaced the old motor with the new and screwed everything back into place.

First I removed the single screw holding the lens assembly in place. Then I lowered the assembly and tilted it until it came out. To remove the existing cracked glass lens there were four tabs bent down on it. By hand I lifted each tab just enough to remove the broken lens. I then replaced the broken lens with the new one and re-bent the tabs down by hand to secure them to the new lens.

The lens assembly, now removed, revealed the cavity that contained the two halogen bulbs. Since they were both burned out for days, they weren't hot so I could pull each one out by hand. The bulbs are secured by two straight heavy gauge wire leads and provided a little resistance but come out fairly easily. Make a mental note of the angle they came out so it will be easier to replace them with new ones.

You're not supposed to touch halogen bulbs with your bare hands, so I used the bubble wrap they came in as a means to hold the bulb while installing it.

Be sure to insert the bulbs at the same angle they came out so the pins do not get bent.

Once both bulbs are in place, replace the lens cover assembly by putting the end opposite where the screw hole goes in first on the right, then swing it up until flush and screw it down.

First I unplugged the microwave. :) Then, I removed the 6 screws found underneath the microwave, which allowed the bottom piece to hang down so I could see the turntable motor. I took the two screws out holding the motor in place and pulled the electric connectors off the motor terminals. Then I got the new part from PartSelect.com, replaced the electrical commectors, fit the motor back into the slot it came from (cause the pin has to be seated up in the hole) and replaced the 2 screws holding in the motor. Then I put the bottom metal piece back up and put the 6 screws back in. It was really easy - and I'm a chick! ;)

Had to take unit off wall and disassemble the main casing.then disconnected the wires from the magnetron.took the mounting nuts off but wasn't able to remove the magnetron until I loosened the transformer out of the way .Then it came out easy.Installed the magnetron ,tightened the nuts,installed the transformer back in, connected the the wires back on and installed the casing on ,screwed the screws and got help to install the unit to the wall again.....Tested the unit before putting back on the wall to make sure it heated....The parts were exac same type and wasn't too hard to do...

Unscrewed bottom plate of microwave and two screws that secured motor. Disconnect wires. Reversed process when installing new motor. Couldn't have been easier.

The tray drive motor arrived quickly. I opened the package and made sure the correct motor arrived. I shut off the power to the microwave/exhaust hood. Then I grabbed a screwdriver and dropped 5 screws from the bottom of the microwave. I then removed 2 more screws that hold the motor in place. Unplugged the 21 volt power clips. Placed the new motor in position and replaced the screws and attatched the power clips. I then placed the bottom pan in position and replaced the 5 screws that hold it to the bottom of the microwave. Turned the microwave on and it worked properly! The total cost was $40 and I probably saved more than a hundred dollars on a service call. What a happy ending and it took about 5 minutes to perform the repair! Thanks PartSelect. You are the best!

Turned of f the circuit breaker to the microwave. Unscrewed the cover (1 screw!) popped out the old bulbs and plugged in the new ones, using the bubblewrap as a handle to be sure my skin didn't touch the light bulbs so the oil from my hands didn't damage or shorten the life of the new bulbs. Turned the circuit back on. That's it!

Inserted new greese filters by unscrewing fan and light holder over range. The new filters were 1/4 inch shorter than older filters and are loser than the original filters, but they will work. Not sure if I inserted them correctly, and would like to see instructions on how to insert filters of that type. Thank you for your fast and curtious service.

1. remove microwave from wall
2. remove cover (many screws)
3. remove nuts holding magnetron in place (4)
4. remove magnetron (this is a pain due to the plastic molding used to direct cooling air through the magnetron
5. get new magnetron in place (this was even more fun to find the right angles to tilt to get the magnetron to fit
6. re-tighten the 4 nuts on the magentron
7. put the cover back on
8. put the unit back on the wall.

bonus repair: the display flickered while the magnetron was on (cooking ) prior to the magnetron dying. found a ribbon cable on the control board to the display with an aluminum foil shield that had peeled off (adhesive failure). re-installing the aluminum shield with packaging tape, and the display no longer flickers

Over the range microwave. Replaced magnetron. Completely disassemble the case top and bottom.
Remove screws from bottom of HV transformer. Magnetron will not clear without this removal.

Remove nuts with socket from top of Magnetron. Remove thermo unit from old magnetron and attach it to new. Replace and bolt down Mag. Replace and screw in HV transformer. Make sure all wires are reconnected.

Put it back up on the wall. Took about three hours from taking it down from wall and putting it back up.

Just took the old filters out replace the new set without any tools. Was easy to install.

First I disconnected the power and opened the door. Then I removed the top screws holding the top vent louvers, then removed the screw at the top of the touch pad. The touch pad removes by sliding up slightly then tilting top out. I unscrewed two screws holding the door latch assembly. Press the tab to remove and replace switch. Reconnect wires, reseat latch mount by placing top bracket tab in place first, allign and secure with screws. Reseat touch pad by placing bottom tabs in first, tilt forward and press up to seat top tabs, secure with top screw. Secure vent louver screws, plug in and watch your microwave work again.

Remove microwave outer cover. Turn on side & locate the upper & lower door switches. Better to replace in pairs even if one is ok. Remove the wire harness to each switch. Then replace switch and re connect the wire harness. Re attach outer cover
and test to see if that solved the problem. If so then well done!!

This is the second time that this lamp hase gone out. It is located in a small space in the top of the microwave and you need to remove the top front pannel, then take a screw or two out of a metal shield and bend the shield up to get your hand into the compartment where, if you know how, you can reach in and lift out the reflector shield that the lighbulb is plugged into and remove the old one and plug in the new one. The first time was hard to figure out how to do it but the second time wasn't bad because I knew how to do it.
