JB940BY1 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.

This was really easy, and pretty with no problems or issues It took me longer to write this than to do the actual installation. I used a digital camera to help me remember where things were, but a pen/paper works fine. Here's what I did:

1. Turn off the breaker for the cooktop.

2. Remove (2) 1/4" hex screws directly under cooktop. You may need to open oven door to reveal them.

2. Prop up cooktop. I used the box the replacement element came in.

3. The element is held in place with (3) brackets held in by a #2 philips screw each. Mark the location of each of the brackets. There are numbers on the element to help you do this.

4. Write down where each of the wires connects to the element. There's only a few of them, but I tend to forget that stuff. The wires have female spade-type connectors that connect to the male ends on the element.

5. Using a needle-nose or small pliers wiggle each wire off the element. Grab the wires by the end of the female connector when you do this. I found it helpful to use a small flat screwdriver to help pry them off. Mine were on pretty tight, so expect this to take a few mins. If you have problems getting to the wires, remove the brackets (next step) first and come back to this one. I let the element hang from the wires without any problems, but I still wouldn't recommend it.

6. Remove each of the screws with a #2 philips screwdriver. Support the element with your hand and gently pull each bracket away from the element. Once they're all gone, the element should just come out. I took a look at my old element and saw that the large burner wires were melted in a couple places, so it was definitely broken.

7. If necessary, clean the underside of the cooktop surface with a clean papertowel. There was a little dust from the old element on mine.

8. Connect the new element and test to make sure it works by turning on the breaker and turning on the burner for a second or two. Note: This will make the top of the element hot for some time, so test it and go away for a few mins. If it works OK, proceed. If not, disconnect and figure out what else may be wrong.

9. Using the old element, make copies of the marks you made for the bracket locations onto the new element. You'll have to punch through the insulation when re-attaching the screws.

10. Re-wire the new element, if necessary and re-attach the brackets over the marks you made. This may be a pretty tight fit because the new element was thicker than the old on mine. I opened up the brackets a bit to make it not so hard to re-attach. Hook the brackets on and squeeze them over the element. The holes in the brackets need to line up with the holes drilled into the bottom of the element. If they don't, spin the element around (or detach and re-attach the brackets) till they do.

11. Screw in the (3) screws over the brackets pushing them through the insulation on the element.

12. Close the cooktop and reattach the hex screws under it (1/4" hex).

13. Turn on the breaker and test again.

Thats it, works great now. Good Luck

Repair was very simple. Removed 2 screws under the cooktop, tilt the cooktop back, unplug 4 wires from 8" burner, remove two screws holding retaining clips, install new burner in reverse order. Very simple!

Fan motor has to be removed from the rear. Since this is a (double) wall oven, the hardest part was sliding the oven out of the wall.

First, doors are removed, eight screws that hold the oven in place (along the side of the doorways) are removed. The rear panel inside the oven must be removed to expose the fan. Four screws hold that in place.
Next, slide out the oven. The fan is covered by a tin shroud which is easily removed with a nut driver. The blade of the fan (inside the oven) is held on by a reverse threaded nut which must be removed. The fan motor is mounted with three screws and has two wires plugged into it. Piece of cake.

Reverse the procedure and you're done.

The best part was that I had originally called a service guy, who was going to 'defer me to GE for the repair' because the oven had to come out of the wall!! I think I'm going into the repair business!

Open lid,un screw coil,pop in new coil snap holders in place,then cook a steak

Old gasket had become brittle. Was able to find the 22 yr old model and part on PartSelect (could not track it down on GE's site. Inner panel was removed with four screws. Old gasket came out. Installed new gasket making sure the bead fit into the groove provided in the door panel. Re-assembled. All is well. Thanks

The outer ring on the adjustable large haliant surface burner of our smooth top stove would not work. It would only work on the small (inner) size.

Found the part on this site, ordered, 3 days later, and it was fixing time.

2 screws removed to lift cooktop, 2 screws to remove old burner and disconnected 4 electric clips one at a time and placed them in same position on new burner. Replace the 4 screws and done.

VERY SIMPLE.

Unplugged range. Opened oven door and removed two screws from top of oven opening. Lifted oven top and propped up
with a 2 x 3.Unscrewed the two screws that were holding

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!

1. Removed the back panel.
2. Disconnected the wires from the old switch while connecting wires to the new switch one at a time.
3. Installed the new switch and broke off the excess metal on the post which fits into the burner knob on front of the range.
4. Replaced the burner knob and replaced the back panel.

-Turn off breaker
-Undo the two screws that hold the top surface down
-Prop up top surface with a board
-Remove two screws/spring clips holding burner
-Transfer electrical plugs to new burner (this was the most challenging part)
-Screw new burner in place
-Lower surface
-Secure surface

Successful repair to Our GE range, manufactured prior to 1965 (when installed in house). Pulled range from wall, unplugged, removed burned-out broiler element. Previous check with GE to make cross reference of range part number to Part-select part number for this nearly 50-year-old range. Obtained new part and installed. Works. Range has self-cleaning oven, accidentally destroyed thermal switch attached to element mounting bracket, difficulty with frozen mounting nut. Self-cleaning still works; thermal switch locks out a solenoid which defeats door latch; prevents premature opening of oven door when oven too hot to open safely. Internet search did not find GE part but there are generic devices of the same type available; will consider installation later.

FIRST TURN OFF THE CIRCUIT BREAKERS THAT POWER THE COOKTOP!! Remove the cooktop from the counter by removing the screws from the mounting straps under the counter. Then remove the screws that hold the glass cooktop to the frame and lift off the glass top. Next lift up the bad element and unplug one wire from the bad element and plug it into the new element. Make sure to put it on the exact same terminal of the new element. Do this for all the wires. Remove the two mounting tabs from the old element and put them on the new element. Turn on circuit breakers and your done.

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.
