GRML3640ZWW-1 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.

The existing terminal block on my Ge oven/Range had melted due to a loose wire causing sparking and starting the plastic casing of the terminal block on fire and melting it, Part select made the part easy to find and had it at my house in 2 days. All I had to do was remove six screws to take the back sheet metal cover off of the oven. Unscrew the terminal connections remove two mounting screws that held the terminal on to the oven body. This was a little trickier than it should have been because the melted plastic had reformed making it very hard to access the mounting screws. i then mounted the new piece and plugged the oven in, it took 15 minutes and was very easy. definitely saved me at-least a $100 for the service call i would have made if finding the part wasn't so convenient

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!

We took out the philips screws on the right and left side of inside of the oven and two hex head screws on the clip on the top of the oven in the front. Then using a slot screw driver pryed the oven liner out enough to remove old gasket and replace the new gasket. We did see in some online directions that we were suppose to remove entire oven from cabinet and loosen bolts in the back. But, we were able to get enough space to get the old gasket out and new one installed. We did use a 1/4" thick piece of wood on face of oven to prevent any denting of oven when prying out the liner of the oven.

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!

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.

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.

After several temporary fixes, one of the end caps finally broke completely, so the handle fell off. Ordered both caps, they arrived remarkably fast, and were installed easily.

No problem installing oven sensor, but I diagnose the problem wrong, I need to change(ERC-11)control p/n wb27k5140

Took oven door off. Removed screws that were holding oven insert. Pulled out oven insert. Removed old gasket. Installed new gasket. Push oven insert back. Installed screws. Replaced oven door.

Son-in-law unscrewed oven compartment; broken gasket was easy enough to remove and new gasket easy to replace; only problem was oven door would not shut tight. Tried shoving gasket harder into groove, tried turning on oven and heating new gasket to see if it would soften. Finally got it to close by pushing hard on left side of oven and inside light would at least go off and stay off.

Safety first * Unplugged 220 VAC from outlet. Removed shield cover screws with 1/4" hex nut driver (5 screws). Removed all 6 silver screws from terminal block with 1/4" nut driver, freeing all wires. Removed the green ground screw and ground bracket from center terminal. Cut away (using the drill) melted original terminal block plastic to access the 2 black 1/4" nuts holding original terminal block onto appliance. Discarded the original damaged terminal block. Attached the new terminal block, aligning the mounting holes and the terminal block the same way the original terminal block was lined up and re-used the black 1/4" nuts (original used because the replacement package did not include new black screws). I bought a new appliance cord, since the original cord overheated. Reattached all wires using the 6 new silver screws. Start with the middle terminal by attaching the appliance wires and the ground bracket. The ground must be attached to the bracket and the bracket bridges between the terminal block and the range body. Reattached shield cover. Plugged in appliance. Note: it doesn't matter which outside wire attaches to the outside terminals (both are hot), but the middle wire (neutral) must attach to the middle terminal. However, the ring terminal should be flush on the terminal block so you don't bend the ring.

the first end cap broke when I tried to tighten the screws, the end cap holes were too small, Thirty some dollars down the drain. Drilled out the second end cap before I tighten the screws, worked fine. Make sure you drill out the holes of the end caps or they will split out and you lose your money. There are no warnings about this problem.

very easy remove the bad bulb install the new one
