FMV145KS001 General Electric Microwave - Instructions

I had no idea what to expect. I was tired to see this turn table not moving. I removed the 7 screws at the bottom of the microwave that I thought was hiding the turn table mechanism. Bingo! I removed the 2 screws holding the motor and check if the power was coming to the motor and it was. The motor was cooked.
I decided to change the filter since I was working on this. When I received it, and proceeded to change it, I found out that there was no filter. Finding the right position was a bit tricky. The most difficult part was to remove the front vent grille.

Don’t be shy, try it! Make sure, to disconnect the power when changing the filter.

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!

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.

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.

Philips head screwdriver to remove 2 screws holding plastic grill above microwave door in place. Old Filter lifts out slide new filter in. It rests on an angle. Re insert Grill (careful that plastic tabs slide into proper slots). Tighten SCrews

This repair could not have been easier! The website was great at helping to identify the problem and the part needed. Users discribing how they did the repair gave me the confidence to do it myself. I got the part the day after I ordered it, installed it and my microwave was a good as new! It was as simple as unscrewing seven screws to remove the bottom of the microwave. Then two more screws to remove the part. Unplug the broken drive, plug in the new one and screw everything back together! Don't forget to unplug your microwave before you begin.

Great website!

remove old film, apply new film. real easy. no magic

I first took the filters of the exhaust and then removed the screws on the bottom of the combination microware hood fan. Once the 6 retention phillips head screws were removed from the bottom of the microwave, and the hinged bottom "door" lowered the motor was exposed. I removed the motor by removing the two phillips screws and unplugged the motor. The hardest part was finding a replacement on the net because most shops did not give enough details or pictures to know if a part was exchangable or a replacement. Partselect.com listed the parts, motor voltage, and had pictures so that I was comfortable with ordering. The part arrived the day it was scheduled to and I simple reversed the process and within 5 minutes I had the microwave motor in and back together. It is nice to do business with a place that also gives you a returns policy upfront.

Removed upper cover. Removed screws in cover plate & motor mount. Removed inner cover with pop screw inside microwave. Reversed procees to install new motor.

Had trouble isolating the problem, so I had a repairman identify the problem, then I ordered the part and replaced it myself.

Removed screws holding the grill in place. Removed air filter, removed screw holding plate under the filter in place. Reached in under fan cowling to find the thermostat cut-out. Disconnected the two wires. Put the new thermostat in place. Replaced screws plates and filter in reverse order.

I initally thought the problem was the turn table motor but after installing that motor & not being successful I realized the problem was the stirrer motor.Removing & insalling that motor was a bit more challenging but worth the effort as I saved either the cost of a repair technician or the puchase of a new one.The microwave is back in service & running fine.
