JGBP90MEB6BC General Electric Range - 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.

Really simple..Opened the top of the oven and followed the four wires hooked to the igniters on the burners to the back of the oven. Unscrewed top section in back of oven. Found spark module screwed to uppper back of oven on right side. Used a nutdriver to take a few screws out of upper back of oven. Unscrewed spark module from oven. There are six wires - four to the burners and two to the power supply....Wires are attached by connectors so didn't have to do anything but pull the connectors off the old spark module one at a time and push them onto the new spark module matching postion of each wire. Screwed spark module back onto back of oven. Screwed back section of oven back onto rear of oven, and that was it. Works perfectly. Saved more than $100 for service call and whatever elevated price they'd charge me for the spark module.

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

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!

It took considerable time to remove the door and take it completely apart so the gasket could be inserted, and time again to reassemble properly. The gasket (though the no. was confirmed before ordering) was 3" too short so I had to cut some off the old gasket to make do (not entirely effectively).

removed two screws with screw driver,and replaced panel

I loosened the three gas line fittings on the valve, removed the two screws holding it to the frame, and removed the four wires (spade connectors). Then I reversed the process to install the new valve. It was that easy. This was my last resort after replacing the temperature probe and the control unit. It fixed the problem.

The first step was to determine whether the problem was with the fan itself or the switch. I did this by opening the back cover and using a Volt meter to verify that the fan was not getting power. (I could have skipped this step.)

Next, I unplugged the range, closed up the back cover and lifted the range hood by removing two hex head screws that are just inside and on either side of the top of the opening in the range door. Propping the hood open, I removed the connector leading to the switch, then pushed the switch out the front. Inspection showed that the switch was damaged so I closed up the range and ordered the part from Part Select. Once the part arrived, it was a 15 minute job to unplug the range, lift the top, install the new switch, and close up the unit.

Caution. On starting to install the switch, I failed to unplug the range and my finger brushed one of the hot contacts leading to the switch. Thankfully, I was not injured. Do not repeat my mistake on this issue. Unplug the range even if you're only installing this simple switch.

While i was inserting the new lp,gas orriface to the right rear burner tube I dropped the oriface.Without looking i popped the top of the burner unit, like most older type stoves, and thats when i ran into my problem. I realized the burner tube assemblies are attached by 3 screws to the top cover.Not attached to the cabinet as the older models, Basically cracked both front aluminum tubes trying to retrieve the dropped oriface. so i had to replace the burner tube units, which involved removing 3 screws, and loosing up and removal of the nut to the main gas tube. extremely easy repair, next time i`ll try to remember look before i leap,total time to (r+r)burner tubes about 20 minutes.Parts select pulled me out of the fire on this one, great staff and service, with quick delivery.

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.

I was very pleased with how quickly the new oven rack arrived and it was a perfect fit. Thanks.

Here's how I fixed my problem.
I took the aluminum cover, the part that sits over the jet & the igniter, which simply comes off. It's the part that the igniter discharges to. I took this cover off & using a pencil I scratched the lead of the pencil into the area
which is around the igniter. I made sure to cover the area with as much lead as I could get on it. You need to make sure that you do this to all four burners. The only care you need to take, is not to block the gas jet which is in the igniter recess. It's been about 3 weeks since I added this & the burners click loudly & have lit without a problem. It appears that the aluminum may develop a coating on it of some kind which is highly resistive.

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!

Pull plug and shut off gas! The lower oven burner is held in with two rear and one front screws. I removed the top floor of the oven (two hand tightened screws at the back), the bottom drawer, and the front door (just lift it off the hinges). This allowed me to access the burner, and I removed it by unscrewing the three screws, unhitching the igniter connector, and lifting the burner and igniter up and out. I connected the new igniter on the new burner before installing it in the oven, and found that the connector did not match (I was warned about this possibility on the PartSelect site), but instead of splicing the wires together, I cut off the connector on the new igniter and replaced it with the connector of the old igniter. Then I screwed the burner into the oven, recoupled the connector, replaced the floor, drawer, and door, and I was done! It took about 45 minutes.

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.
