EMO3000HBB01 General Electric Microwave - Instructions

I was able to simply lift the broken turntable coupler from the bottom of the microwave. The smaller broken piece fell inside the body of the microwave. I tried unsuccessfully to retrieve it. When the new part arrived, I simply snapped it in place. Everything works good as new!

Unplugged the microwave first, then removed the screws that hold the cover in place. This gives easy access to the socket. Remove the screws that hold the socket in, unplug old socket, replace with new one and you are back in the light again.

There are 4 thermostats (aka TCO = Thermal Cut Out) in the GE JVM1440BH04
The schematic is under the cover in a black envelope to the top left of the unit if you face the door.

Check the fuse first. You can remove the front grate, then the numpad on the right. The fuse is right behind it. It's a 250V 20A Class F fuse.

There are four (4) TCOs or Thermal Cut Out thermostats in this puppy:

1) There is a thermostat behind the button panel to the left, facing down. If blown, it breaks the power coming into the unit and will cause a no power situation.

2) There is another TCO or thermostat near the top lamp, to the left, in a small cavity. That one also breaks power to the unit and will cause a no power situation. It's a 100 C / 0 C thermostat. This was the one that blew on me after I left the stove running (for heating in a black-out) under the microwave.


"Cavity TCO" or "Thermostat" part number 61 on the schematics, part number PS239319


3) There is yet another power-breaking TCO or thermostat in the cavity behind the fan that cools the microwave coils. You have to remove the sheet metal on the right of the microwave to access it. This one also breaks power and will cause a no power situation.

1), 2) and 3) should test out to be 0 Ohms with a resistance meter (Digital Multimeter) if working correctly.

4) There is a thermostat which normally does not let current through it. It is mounted in a vertical position to the back wall behind the front panel on the right. This one is used for the sensor reheat function apparently and will close when the temperature in the microwave reaches approx. 60 C.

4) should have infinite resistance with a resistance meter under normal circumstances.

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.

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

Open the microwave door and remove the plastic frame around the glass. Easy to crack and fragile. Use a small flathead and gently pry the frame it will pop out. Unscrew the handle screws on the inside of the frame you just removed. Handle will easily come off. Use the same screw driver and remove the front outside frame again plastic and will break, but since your replacing it...who cares if it cracks. Again, pops off from the holding brackets. IMPORTANT......REMOVE THE TOP FIRST. THE GLASS WILL SLIDE OUT AND DROP. NOTHING IS HOLDING THE GLASS IN EXCEPT THIS PLASTIC FRAME. Piece of cake from here int...

After reading some of the comments that others wrote, I decided to order the light sockets along with the replacement bulbs. As predicted, the old light bulbs broke when I tried to remove them - the bulb separated from the base which was still screwed in the socket. After removing the screws that held the bottom panel, I was able to remove the socket assemblies with ease. After inspection of the old sockets, I was glad I ordered new sockets - the old sockets were burned in some spots and very brittle. The parts arrived within a day and a half after I ordered them, but when the parts arrived, one of the bulbs was broken (happened during shipping). I called the office phone number and talked to a really pleasant technician who refunded me the price of the broken bulb and placed an order for a replacement. That was the Wednesday evening before Thanksgiving Day. I got the replacement bulb yesterday (Tuesday) morning - still really quick considering the Thanksgiving holiday. All of the parts are installed and are working excellent. I am definately going to keep their WEBsite for future use, and I'll be letting my friends know about them. Thanks PartSelect, you've earned my business.

The old fuse is perfectly good. The new ones arrived within a day.

First, I waste $65 by calling some "REPAIR" service. They showed at home and charge me that just to tell me
Second, I researched on the web and ordered a part, which was not the issue. I waste abnother $72
Third, I found Part-Select and got the right answer: the Diode was the problem. Ordered the part form Part-Select and it FIxed it !!!

Note: I did not buy a new microwave because this one is mounted on the wall and it will cost me +$800 just the lowest price.

1. turned off electricity -- unplugged the unit 2. removed 3 screws on top of top vent, removed vent screen then I located the little white cylindrical fuse and popped it out with a table knife. Then I popped in the new fuse. Replaced the vent screen and screws -- plugged in the appliance and it is working again.

I ended up breaking one bulb trying to remove a burnt bulb for replacement. We then tried removing the other bulb and it wouldn't come out either. I googled the problem and found PartSelect and an explaination of the problem. Heat from either the stove or the bulbs had fused the bulbs into the sockets. Comments on the problem explained that you just remove the bottome pannel (we had seven screws), unplug the old sockets, insert the new and new bulbs and reattach the panel. It was quick and no problems to correct. We did discover the microwave was on its own breaker, make sure to disconnect or cutoff power to the microwave before you start.

This did not fix my problem. I've ordered a new microwave.

First off, UNPLUG THE MICROWAVE.

The fuse is located under the plastic grill at the top of the microwave. It's held on by two screws. Once you've removed the screws and taken off the plastic grill, you go to the right side of the microwave and remove another screw that holds a small metal grill in place. Removing the small metal grill is probably the toughest part of this repair. You kind of have to rock it back and forth a bit to get it to release. Once that's off, you can get to the fuse. I removed the burnt out one with a pair of needle nose pliers. I also put a small piece of cardboard under the fuse when I did this so I didn't accidentally drop it into the innards of the microwave. I did the same thing when I replaced the new fuse. I then plugged the appliance back in and made sure it worked. Once that was confirmed, I replaced both grills.

I removed the inner flexible plastic door frame (light grey) which allowed me to get to the screws that held the handle. I then carefully pryed the broken outer door frame off by pulling each side down and out. Next I removed the glass door front from the broken outer frame and smapped it into the new outer frame. I attaced the new handle with one screw to the top and one to the bottwm on the new outer frame. Finally I snapped the entire outer frame back on the microwave and added another screw to the top and bottom of the handle. Hint: These plastic parts are extremely fragile so use great care when snapping the parts back onto the microwave.

turntable coupler was an easy switch from inside the cooking area(pull out and push in the new part).The light sockets were accessed by removing five screws under the microwave,lowering the panel and replacing the light sockets(one screw in each and two electrical plugins)simple....

The grill is located on the top of the microwave - above the door. The plastic seems to have just deteriorated - the plastic around the screws just cracked. There was also another crack on the side of the grill assembly. The micrawave is fairly new (4 years old) and we don't use any harsh cleaners on the plastic grill because it has never required it. The unit is also vented to the outside - so it doesn't get exposed to alot of heat. To put on the new grill - it took 5 minutes, two small phillips head screws. My only question is why did the plastic just fall apart
