It is possible that your oven is cold because of a fault in the temperature sensor. The temperature sensor regulates oven temperature in modern ranges, like a thermostat. It is on the back wall near the broiler on the top wall. On a newer oven, there may be a fault code displayed. Faulty temperature sensors are often responsible for F3 and F4 error messages on an electric range. Check your manual or the manufacturer website to find out the proper resistance of the temperature sensor. To check your sensor, unplug the oven and use a multi-meter to see if your sensor is at the correct resistance.
This part works with the following brands: GE, Hotpoint & Kenmore.
This part fixes the following symptoms:
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.

My Hotpoint gas stove was not operating at normal temperature. This was operating in a basic range of 125 - 100 degrees below normal. After going through numerous troubleshooting posts, I came to the conclusion the sensor was my first place to check. I did not want to drop $100 for a sensor if I did not need to, therefore, I decided that I needed to know how many ohms the sensor registered in my stove. The sensor need to be 1100 ohms and after using my digital multi-meter,( Analog meter would do for this job as well) sure enough the sensor did register 1100 ohms. I then started troubleshooting other components such as igniter, gas values, etc... All resulting in everything testing out good. That is what really puzzled me. Other posts of people having similar symptoms as my oven always came back to the sensor as the problem. Then I noticed that the cleaning temperature of the sensor needed to be 2600 ohms or somewhere in that range. Therefore, I heated up the oven and tested the temperature of the heated sensor and my sensor registered 1650 ohms. I concluded that the sensor tested good at room temperature, however when heated up, it was not registering correctly. I took a chance and purchased the senor, installed the sensor, which was quite easy and only reqired removing a few screws inside the stove, removal of back panel, and unconnecting the wire attachments, and the oven now operates as new, and just in time for Thanksgiving. The really great thing was that I was a hero in the eyes of my wife this Thanksgiving.
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!
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.
No problem installing oven sensor, but I diagnose the problem wrong, I need to change(ERC-11)control p/n wb27k5140
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.
