RGB740BEH3WH Hotpoint 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.

I could not get these grates clean, so I called Partselect and they helped me find the model of the same stove that had black grates, drip pans, and burner caps. I ordered the black grates one afternoon, and without paying for expedited shipping, they arrived the next day! They were in original GE boxes (since they make Hotpoint). I am happy about the whole experience.

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).

First I needed the correct model number & the correct part numbers for the two front tube assemblies. After that well.... I removed everything on top of the stove. I then proceded to remove all the torx screws for each orifice holder bracket & igniter wires so i could raise the top lid ( without this step you will wind up replacing more than one tube assembly!) Be careful when removing color coded wires so that they work with the correct burner. Remove compression nut to burner valve... i used a crowfoot. remove orifice holder from bracket & install new holder ( onto bracket). Install orifice assembly to burner valve ( do not over tighten), re-install wires to igniters, lower lid, and re-install torx screws. The correct parts require little effort to align. Last of all, test burners and check for leaks. Thanks for reading, I will continue to learn from my mistakes!

A G.E. tech came out and quoted $500 to replace the circuit board. I unbolted the board myself and used the camera in my phone to take a picture of the wiring. Then I came to PartSelect.com and using their diagrams found the replacement board for $75. It came in the mail a few days later. I used to picture in my phone to reconnect all the wires, bolted everything back up and baked some cookies. Thanks PartSelect for making my repair job simple and inexpensive.

replaced all four top burner spark electrodes. the same two still didnt work. I had also purchased spark module and that did fix the problem. Lifting the cook top was difficult. I was afraid of breaking the sealed burners. Note there are directions in envelope on the back side of the stove. /use pliers to remove connectors from module. >Getting the top open was the hardest and most time consuming.

Really self explanatory. Removed the old drip pans and put in the new. No tools required. However, I would like to say I received the parts the day after I ordered them. EXTREMELY FAST SHIPPING!!

openend stove top disconnected wire pushed out old sparker inserted new one closed lid game over

Removed the two screws put the heat shield off the old one onto the new one put new bottom in and tightened two screws. Done #38. 69 Cost of part with shipping cost included.

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.

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