JB553GM1 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.

First I removed the door by lifting it off the hinge assemblies.

Then I removed the drawer to access the spring.

Removed the spring, noting which attachment hole was used.

Removed the hinge assembly with a Phillips screwdriver.

Replacef the unit.

Repeated for the other hinge assembly.

Note: it took longer to find the correct parts in the parts diagrams than it did to replace them.

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.

Downdraft stove is over 20 years old, but everything else works fine and it would be a real pain to replace it.

This quick-heat back burner is part of a two burner plug- in unit which takes up half of the top of the stove.

I removed the top from the rest of the unit easily removing five screws. Because of the age and long use it was tough getting the old nut off which holds on the disc, but with the help of some spray lubricant it came off. The old wire ends were also rusted, and to get them off I bent up the old holder, which was going to be discarded anyhow. It was a simple matter to plug in the new unit, tighten the nut, clean up the lubricant with a paper towel, and reassemble the unit, which I cleaned inside since it was dusty. After plugging in the unit I turned on the burner...it works like new and has saved me a very costly replacement. I like it so much that even though the front element works perfectly I am considering buying that disc too just so they will match. Finding your company was absolutely great, and I would recommend you to anyone looking for parts. I still have the manual for this stove so I would feel confident in replacing pretty much any part needed....not bad for a 72 year old woman, (My Dad taught me to do my own work and I am a passable carpenter and plumber; a little more wary when it's something electrical !

Before removing screws, I reached in and felt for where the upper end of the spring attached to the hinge. There are three holes in the end of the hinge arm, so I wanted to be sure of which hole to use. (The holes are very close together, so if the spring falls out before you determine which hole it was in, it probably won't matter so long as you are sure to use the same hole on both new hinges.) I then removed three Phillips screws per hinge. Once the hinge was loose, I could wiggle it around and release enough of the spring tension to slip the top end of the spring out of the hole on the hinge arm. Then I pulled out the old hinge and inserted the new one and replaced the three screws. Without the tension, the lower end of the spring fell out of the little hole in the oven bottom where it normally attaches. Our gas oven has a broiler rather than a storage drawer, so it was a little difficult to get the lower tip of the spring back into that hole. It actually ended up being easier to get the lower tip of the spring back into that hole first, before trying to reattach it to the hinge arm. Once I got the lower end into that hole, I pulled up on the spring and maintained upward pressure on the spring while I fiddled around to get the upper end into the hinge arm hole. Took about 20 minutes, door works perfectly now. Lots of sharp edges inside the oven, so had to be careful.

Pull oven door open about a couple of inches. Grab the door by the sides and pull up to remove from the hinges. Set it aside. Remove the storage drawer under the oven. This gives you access to the tension spring attached to the hinge. Detach it by hand. Using a phillips head, unscrew and remove the damaged hinge. Replace the new hinge. Reattach the spring. Replace the storage drawer. Replace the oven door. Done.

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!

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.

Snapped in the clip

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

I used a socket set to remove broiler element. It was stiff after so many years, but no problem. All was going well until I pulled too hard on the old element(I'd recommend jiggling if stuck, not yanking) & 1 of the 2 connectors pulled loose & fell behind the back. After my initial panic, I summoned my courage, unscrewed the coverings in the upper back of the stove, found the lost connection, pushed the new element ends through the holes from inside the oven (easiest way to hook it up at this point), plugged it in from the back, pushed it back thru into place inside the oven, reattached everything (front & back), & it worked PERFECTLY! Had I not made a mess of it, it would have taken approx. 5-10 minutes. As it was, it took approx. 15 minutes. EASY!

Disconnect power. . . Remove control panel, pull wire connectors,[note location] remove old switch, install new, install wires, snip stem to length, set knob . . . Turn on power - works. [Note this is a live part even when not connected]
