JCAP750WM1WW 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.

After unplugging the range I took the rear sheet metal panel at the top off with a nut driver to expose the wiring connections. The next step was to remove the single screw holding the old part in place. (under the drip pan) Once free I snipped the old part from the wires and then taped the new female ends to the old wires with black electrical tape. From rear I carfully pulled the old wires through the back until I could reach the new wiring connections. Unplugged old, plugged in new and replaced the rear metal cover. Then I put the screw that holds the new block bracket in place, replaced drip pan, and burner. The final step was to plug the range back in and check to see if the burner worked. It did and I was done. Approx. 5 minutes

Remove nobs from both switches.
Pull out the range (the hardest part).
REMOVE THE POWER PLUG FROM THE WALL
Remove 7 screws with nut driver and take off upper back panel.
Remove 2 phillips screws from front, they hold the switch brackets.
The new switches don't fit in the bracket so discard the bracket keeping the screws.
Removing 1 wire at a time from the old switch transfer to the new noting the letter/number ie "H1 P1" combos they are all there just not in the same places on the new switch.
When wiring is complete, using the bracket ,screws from the front screw on the switches.
Replace the back panel with 7 screws.
In my case the old nobs did not fit the shafts of the new switches. I found some at the local hardware store. I bought 4 for $0.29 each! I expect to be replacing the other burner switches shortly.

unplugged unit pulled it away from wall took off the backplates traced wire to plug replaced with part ordered very smooth operation. the most impressive thing to me was i ordered part on computer and it was at my door in 30 hours awesome.

I removed the rear cover from the stove then removed the knob and two screws on the front panel that hold the control in place. I then took the wires off the old control one at a time and placed them on the new control. Then I placed the control in position and tightened the two screws on the front panel, replaced the knob and screwed the back panel in place.

first slide out range from wall and unplug it. then remove the rear panel, it is about 6 or 8 1/4" screws. remove the selector knob on the front of range and then remove the two philips head screws. this is how you remove the burner controller. hold the new controller next to the od one and one by one take the wires off the old one and put them on the new one. re-assemble and you are good to go.

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!

The known problem: a short occured between the surface element and the INF switch. After replacing the wire between the surface element and INF switch. The surface indicator light remained on - indicating a power surge/spike. Prior to removing the old INF switch I disconnected the wires from the old switch one at a time and plugged each into the new switch terminals. Then I removed the knob from the front of the control panel and the 2 screws holding the old INF switch in place. Removed the old switch and replaced it with the new switch. Reinstalling the 2 screws and the knob. Surface indicator light was no longer illuminated and surface element works fine.

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.

First, I got my husband and let him know that the part was in (really easy), then I sat back and watched as he pulled the oven from the wall, unplugged it and lifted the stove top (so far, I haven't broken a sweat)! I then peeped up under the top as he removed a scew from the element and then several screws from the back panel, trace the wire to the needed element, and reconnect the new element (haven't broken a nail yet)! He then secured the element back on its mount, let down the top and plugged the oven back in, checked for accuracy...mission accomplished! This was the easiest repair I've ever done!

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!

Originally the burner had a hole burnt through it, which resulted in a hole being burnt through the bottom of a pan. I replaced the burner and it would not heat up. I removed the top control panel, after securing power to the stove outlet, turned the power back on checked both sides of the swith with a meter (with the switch on) and had no power on one side. I went to two stores that did not have the switch in stock and ended up ordering from this site at about half the price! It arrived a couple of days later. I marked the wire colors on the old switch, took off the knob, removed two phillips head screws, pulled out the old switch and installed the new one and I was back in business. The hardest part was getting the sheet metal / heat gaurd positioned right upon re-assembly. To remove the panel there are two screws in the rear (nut driver) and a screw on either side of the front under each corner that require a torx driver to remove.

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.

took of the back panel with a nut driver,pulled off the wires one at a time ,put them on the new switch in same position as the old switch.removed old switch with a screwdriver ,screwed in new switch,replaced back panel,put on switch knob
