JES1339WC02 General Electric Microwave - Instructions

My repair went very well and it saved me from buying a new microwave oven. When the oven first started malfunctioning i thought i would have to spend the money i really didn't have on a new microwave oven. furtunately the probelm was easily diagnosed and easliy repaired. it cost me under ten dollars for the part i needed. the microwave works like brand new.

First remove all screws holding on outer metal casing of microwave. Next remove the back and bottom metal pieces. You will then be able to pull aside the outer casing so you can access the door switches. Check each switch with an ohm meter in both the open position and with the switch closed. If the ohm meter reads the same in both the open and closed position, the switch is bad. Check the top switch first. Replace switch and reassemble. Cheap fix for a costly microwave. Great customer service at Parts Select!

Disassembled the front cover, found slow blow fuses, then replaced with microwave fuses 250V-20Amp. Utilized a few fuses to pin point the problem, Microwave functions all worked except the express feature, made an assumption after using a tester that it was the high voltage capacitor and the diode that attaches. Replaced both, plugged in and tested. Worked! reinstalled the unit. Sucessfull for the past month.

Everything worked on the display light inside worked but when you closed the door and set time it would start counting down but not heating nor would the turntable turn. Started reading troubleshooting chart and first thing I did was removed the cover and checked door switches and found primary door switch wasn't working so I ordered a new one installed it and it worked. Anyone doing this has to be very careful because of the stored energy in the capacitor is strong enough to kill.
My micro is only 2 years old so I was hoping it wasn't anything major.

Since I didn't know if it was the current fuse or the flame sensor, I ordered both parts, and, I had to order the tamper proof torx bits needed to remove the microwave cover ($7.45 on Amazon). Once the cover was off the unit, both parts were easily accessible on top of the oven and were replaced in only a couple of minutes.

I REMOVED THE TOP PANEL OF THE MICR0WAVE AND THEN REMOVED ONE SCREW TO REMOVE THE CONTROL PANEL. rEMOVED OLD SWITCH. SNAPPED IN NEW SWITCH AND CONNECTED WIRE. REPLACED CONTROL PANEL AND UPPER PANEL.

e.g. First I removed the bottom cover. I then removed the two screws that hold the motor in place. I then pulled the motor out about 3 inches and disconnected the two wires...)
I then put the new motor in with the two screws and hooked the wires back up. I then replaced the bottom cover and put the the turn rack and glass tray back in place. Works great.

Once I unpluged the unit and laid it on its back, I remove four screw and exposed the motor. The motor was mounted with two screws and a push on electrical conecter. I reversed the procedure and it was done.

DISCONNECT THE POWER CORD and discharge the capacitor
Leave unplugged overnight
Remove vent grille by removing the 2 philips screws
Remove the LED panel by removing 1 phillips screw
Disconnect all connectors that plug into back of the LED board completely
Remove the wires from the switches (3) at the inside edge of the microwave door
Gently remove each switch housing and test all three switches for continuity
Carefully replace non-functioning switches and reassemble the panel
GOOD LUCK

Remove the ice bin.
Turn the ice maker selection to "OFF"
Use small flat blade screwdriver to open the plastic ears on the electic plug in connectiion
Use #2 Phillips screwdriver to remove the screw on the front left side of the ice maker
Pull the ice maker forward until free of the two studs in the left side rear of the freezer wall
Check to see if the supplied water chute is the correct size for your application, if not remove the water chute from the old ice maker and place it on the new one.
Place the new ice maker in the freezer connecting the slots on the left read with the studs on the left wall
NOTE; IF THE ICE MAKER DOES NOT APPEAR TO BE LEVEL HORIZONTALLY REMOVE IT AND CAREFULLY REINSTALL IT TO ACHIEVE LEVEL
NOTE: ENSURE THE WATER DELIVERY TUBE RESTS IN THE RECEIVER TRAY
Reconnect the electrical plug ( needle nose pliers may be helpful in aligning the male plug with the female plug)
Move the selector from "OFF" to "ON"
Replace the ice bin and close the freezer door

Remove upper grill, then control panel, then 2 screws hold door switch mounting bracket, that will let you roll the switches out to work on them. Remove each switch by carefully pushing back retainer clips. Diode a long pair of needlenose pliers is helpful. The control board in front of capacitor comes out with a flat screwdriver and pry up. Removing grnd wires helps

First I had to accept the fact that the unit was designed to keep non-professional people from doing any repairs. The switch was installed in such a manner that I had to break the mounting to remove the switch, then drill a hole in the mounting to secure the new switch in place.

unplugged power
removed main black cover.
located part WB24X10047 and replaced

With this model, you must remove the outer covering. Don't try to access the display unit from the front like I've seen in some other GE microwave videos. After removing the outer covering, the switches are easy to replace. They are very visible and easy to get to without taking any other parts off. You will see the door switches just behind the display board. Remove the switch and then remove the connecting wires to ensure you don't inadvertently brake a wire. You will need a tamper resistant star bit to remove 3 or 4 screws from the back panel. All other screws are philips head. I went ahead and replaced both switches (yes...there are two of them) and works like a charm. I saved an $800 microwave for less than $60 and know what to do if it happens again. Appears to be a common problem on this model. Thanks for others making a post...It saved me time and money reading others remarks. Good luck!

remov cover to check voltage and found problem at the interlock switch ohm the switch and found it was open replace both switches it work fine now
