1259 - Instructions

This repair is EASY if you know how to use an ohm meter. If not, seek help for this step.

SYMPTOM:
The oven (JKP27WOP3WG or JKP27WP3WG and many ovens like it ) was not getting hot enough. Verifying the cooking temperature with an typical oven thermometer, I was able to determine that the oven was cooking temperature was about 150 degrees to low.

FAILURE POINTS:
There are two logical failure points (1) The oven sensor ( WB21X5301 about $75), or the (2) the controller board (PS238233 about $252). In my case it was the controller board. When replaced the oven worked beautifully.

REPAIR:
As with any repair, you MUST DISCONNECT POWER TO THE UNIT BEFORE SERVICING!!!

Pull oven from the wall:
- Disconnect power by flipping the circuit breaker to the OFF position.
- Remove the top flange / cowling from the top of the oven (it just pulls off)
- Remove two screws under the top flange / cowling
- The whole unit easily slides out, but it is highly recommended that you use two people to place the oven on the floor.

As a diagnostic between these two parts, if the oven sensors measure approximately 1.1K ohms of resistance at room temperature, then it is probably not the sensor. The oven sensor wires are connected to two white wires that run up to the controller board. You need to disconnect the oven sensor to make the measurement. You may either completely remove the oven sensor by cutting the wire (be sure to allow yourself enough slack so that they may be safely reconnected) where it connects to the white wires, OR, (preferred method) if leaving the oven sensor partially installed,
- Remove the top sheet metal cover (10 screws)
- Remove the service connect cover (2 screws - this is where the main Power cord comes into the unit)
- Disconnect the white wires from the controller board (this connector which also includes other circuits is on the left side when looking at the controller board).
- Remove two screws from oven sensor but just let in dangle down so that you can put the sensor in the ice water / boiling water.

Measure the resistance under the following conditions. Your ohm meter should read APPROXIMATELY...
- 1.02K ohms in ice water
- 1.09K ohms at room temperature
- 1.36K ohms in boiling water.
If you get approximately these readings, then it is NOT the oven sensor. If that checks out then re-install the sensor AND the connector.

If it is NOT the sensor, replace the controller board.
- Take a moment to write down the color of the wire to the LETTERING (N, L, G, C / COM,,,) on the controller board. The connectors are in different locations on the new controller board so the wire color to the letter designation is significant.
- Carefully remove the wires one at a time
- VERY carefully remove the keypad ribbon cable from the right side of the controller board.
-- The ribbon cable will disconnect by releasing some little pressure clips on the side of the connector.
- Remove the controller board (4 screws)
- Install new controller board (4 screws)
- VERY carefully connect the keypad ribbon cable on the right side.
-- Make sure that the connector is in the OPEN position first, then,
-- Slide in the cable ensuring that all parts of the ribbon made it into the connector, then
-- Press down on the connector locking tabs.
- Reconnect each wire to the correctly lettering on the board.
-- Again, the connectors MAY BE in a different order on the replacement controller board. Match color to letter.
- Reconnect the (5 wire?) connector that includes the white oven sensor wires.
- Make sure everything looks normal, (i.e. no wires are pinched, remove tools from top of oven area, etc.)
- Re-install top cover.
- Re-install service connect cover.

You can test the unit while it is out of the cabinet,
- Make SURE that all sheet metal covers are in place.
- Flip power breaker to "On".
- Test that oven gets to the desired temp.

First I removed the oven racks. Then I loosened the two screws in the back of the oven floor and figured out how to remove it. Then I loosened the two screws at the front of the diverter and, with some pushing and pulling and twisting, was able to get that to come out, too. Then I tried lighting the oven and noticed that the igniter was not glowing. When I saw that the upper (broiler) burner was working fine, I hoped that the problem was the lower igniter itself. I checked the wires and they seemed fine. I saw that two bolts held the igniter onto its bracket, so with a socket wrench (which size I got right on the first guess!) I removed those bolts and the igniter came loose. I found the connecter for the wires when I removed the drawer under the oven and was able to pull it apart easily. The igniter came out completely. There was nothing unusual about it, but I decided to take a chance and order a new one, hoping that replacing it would solve the problem. I put the rest of the oven together and waited. About three days later the part arrived (it was sent on a holiday; FedEx is soooo much better than USPS). I retraced the steps of taking the oven apart, put the two bolts into the new igniter to attach it to the bracket, and went back underneath behind the drawer to connect the wires. Then came the moment of truth: I tried turing on the oven. I held the button down to keep the light off, and after a few seconds I saw it: IT GLOWED!! It worked!! After yelling a satisfying "YEAH!!," I turned it off, put back the drawer, the diverter (more pulling and pushing and twisting), and the oven floor. Now it's all working perfectly and it took a very short time to fix. And a little luck that the problem was with such a simple part.

removed the screws holding the back metal panel, this exposed the wires to the switch. tested the wires to find that they were live when the switch was in the off position. ordered a new switch. UNPLUGED THE STOVE. removed the knob on the front of the stove. this exposed 2 screws, removed screws and the switch came away from the stove. removed each wire from the old switch and replaced them in the same position on the new switch. inserted new switch into the stove and attached the 2 screws. replaced back panel and pluged in stove. all tested well

We felt the only possible problem could be the switch assembly. I removed the switch panel, removed the wires from the old switch, one at a time, removed the old switch assembly and installed the new switch assembly. The extended stem did have to be snapped off (per your instructions) and that too was a very simple task.

Pull unit away from wall.
Unplug power
remove topmost four screws from rear metal cover
Pull knob off switch shaft.
Remove two screws holding switch to panel.
Break off shaft of new switch to correct length.
Remove each wire from old switch and attach to Corresponding lug on new switch.
Reattach the new switch to the panel and reverse the first four instructions.

First I removed the two screws that hold the element in place. I then pulled the element out about 3 inches and disconnected the two wires

Easy.... UNPLUG THE STOVE FROM THE 240 VOLT OUTLET & READ THE DIRECTIONS THAT COME WITH THE NEW PART !! Removed upper rear cover panel 8 screws & removed panel, removed knob & 2 screws from front of control unit (on the control panel), pulled the control off the panel from the rear, removed the wires on the rear of control & connected them to the SAME terminals on the new control (one at a time). Then installed the new control by reversing the procedure above. Took about 15 minutes. IMPORTANT HINTS: 1) Make sure you save the little black pressure clip from the control stem on the new control, if you need to break-off the little part at the end of the stem. You will need to push the clip back into the recess on the new stem, in order for the knob to stay on the stem when you put it back on; 2) Use a needle-nose plier to pull the wire clips from the old control terminals & push them onto the same terminals on the new control, one at a time so the wiring is correct.

After unscrewing the old heat sensor from inside the oven, I pulled the range away from the wall, got behind it and removed the small panel over the heat sensor. Naturally, the plastic clips connecting the heat sensor to the range wiring wouldn't come apart, so I eventually had to simply pry them apart with two pliers. Then, naturally, the new plastic connector clip on the replacement part didn't match the clip from the range, so I had to cut off both receptacles and strip the wires, then used the provided wire nuts to make the connections. After that, it was easy, just secured the heat sensor inside the oven and replaced the panel. I didn't push the range back against the wall until I tested the repair. It worked fine!

removed drawer below oven, reached under stove and unplugged from outlet, pulled stove out from between cabinets, removed the 8 screws with 5/16 nutdriver from back panel and removed the panel, removed knob from switch , measured length of stem on old switch and compared it to the new switch ( my old switch stems was shorter than the new one so using a pair of pliers I shortened stem per instructions that came with new switch, this was very easy to do ), removed the two screws holding switch to stove and removed the old switch, then I transfered one wire at a time from the old switch to the new one until I had all the wires connected to the new one, used same two screws holding old switch to the stove to mount the new switch to the stove and put knob from old switch onto the new one, installed back panel to stove using the same 8 screws, pushed stove back into place between the cabinets and plugged the stove into the outlet, put drawer back in place below oven door, reset clock and tried out the new switch, so far so good only time well tell if I fixed my problem because it only happens once in awhile

I removed the unit from the wall,removed the back panel to access the wires to the sensor,cut the plug off of the new sensor and strip the wires back,used the wire nuts to attach the new sensor,put all back together and slid back into the wall and works excellent.

As has been said shut down unit,Breaker fuse.If you do not have install info.Get a copy on line. If you have another set of hands it would not hurt.! this has been stated before. Remove door, Remove 4 screws , to slide unit out,I used a saw horse with some cribing secured to the horse to get height, Pull the oven out so that the two front supports are on the saw horse,and the back two are up to the edge runner.I used about a 1 ft stool for working height. Remove the top elec. cover sheet metal 2 screws. You will see were the wireing runs down the back. Get a small mirror,and flash light. Look down the wire opening in the back, you see the sensor connection ,I made a hook out of a coat hanger to grab it with. Pull it up before you disconnect it ,tie a piece of string to the sensor side of the connector , use 2 Ft. then disconnect remove two screws from inside the oven. And remove,sensor tie string on to new sensor connector pull through and connect.on top.Then replace everything cck every thing Twice!Doing this i didn"t have to pull the unit all the way out! LATER GOOD LUCK!

Removed racks and floor in oven, exposing ignitor assembly. Disconnected 2 wires at electrical connector plug. Removed 2 screws holding ignitor in place, removed bad ignitor, installed new ignitor in reverse order. Tested for ignition, all worked fine.

removed broiler pan
removed oven bottom plate
removed burner cover
unplug and remove igniter
reinstall igniter
clean and reassemble

It was very easy I removed two screws unpluged the sensor and wire spliced it together and also replaced the modual on the top of the stove and it was that easy.

I had to call for a appointment for repair with GE Appliance because I thought then it . .was something electrical. The technician came out & checked everything out, turned out it was not electrical, The technician went out to his truck got a light bulb from his truck, put it in & it worked. It cost me $121.00 for trip charge from GE appliance for a light bulb that worked, your light bulbs were defective twice. Very disappointed with your products, cost me alot of money for a good light bulb thru GE appliance
