JEM25WKC01 General Electric Microwave - Instructions

I ordered a microwave cooking tray from PartSelect; userfriendly site; and within two days, my part was delievered and easily installed. Thank you PartSelect!

replace new tray with no tools needed

none

Took out broken piece
Called GE Parts to order replacement
Upon arrival, opened package, took out new part, inserted it where old part had been.

Opened the microwave door and put the new plate on the carousel. Duh!

I ordered on tuesday right before Thanksgiving and was sick my tray plate broke with a house full of company comming for the holiday and no microwave low and behold i ordered on tuesday and it was at my door on wednesday what a shock i will forever be a loyal customer thanks part select!!!

Just placed the new tray in the microwave. Simple as that.

It was easy. went to GE website and click onto parts replacement. Placed my order and within three business days the new glass tray arrived. How easy was that....

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.

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!!

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.

I unplugged it, removed the outer shell with torque bits and a screwdriver, drained the main capacitor, and began debugging the circuit with my fluke multimeter, found the bad primary interlock, googled the part number, ordered the part, received it in 2 days, replaced the interlock in about 2 minutes, and put the cover back on. Fixed. Saved me about $200 over buying a new unit and was grateful for partselect's great service.

Removed screws holding outer shell. Pushed in door handle to identify faulty switch. Ordered part. Pryed switch out with screw driver and unplugged. reinstalled new switch. Presto. BUT... I did NOT use both hands while working on the microwave. I did not release the energy from the capacitor or whatever holds the killer amperage even when unplugged. It would be advisable to do this first. I did not because it seemed complicated, so I was EXTREMELY CAREFUL about not touching anything else inside the unit. I used one hand only so if I did touch something I would not get juiced through the chest. It was a piece of cake repair, but I would not go deeper without doing the discharge routine.

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.

Had to remove outer cover (special screws involved). Found the correct part at PartSelect.Com and it arrived 3 days later as promissed.

This oven has diffcult electrical connections at switch to get disconnected. I found it easier with the sw loose and in hand so that the connectors can be released with a small screwdriver.

One has to this in order to test the part wirh an ohm meter. I found the sw did not close but remained open and thus caused the oven not to function.

Removing interconnect switch is tricky but not difficult.

Outer cover replacement is not as easy as it should be, especially the sides.

All is well and working.

Microwaves are simple devices if you are know how to read and understand schemetic diagrams.
