I have a 10 year old JTP15WW2WW. The oven comes up to temperature and signals it is ready. After a few minutes the F2 error is displayed indicating the temperature is too high. I have checked the heat sensor with an ohm meter and found it to be approximately 1100 ohms at room temperature. Is the problem still possibly the sensor or should I be looking at replacing the oven control?

Hello. I need the model number of your unit to help you accurately with exploded parts diagrams and part numbers. From what you describe, it sounds like you have a defective oven temperature sensor. There are only 2 things that govern temp in a range--the EOC(main oven control board) and the temperature sensor. It's connected to the main board by a 2-wire harness. Usually, there is a connector at the end of the short pigtail coming from the sensor. The contacts in the sensor can oxidize, breaking electrical connection or, the signal can be lost due to a broken wire, loose connection, etc. Most often, the sensors will have an electrical resistance of approximately 1100 Ohms +/- 10%. Usually, if the sensor checks good, the main board is the culprit. Hope I helped you!
Hello Sonya, The E0-F2 error code means that the oven temperature was higher than it's supposed to be. Usually the oven overheats because of a defective oven temperature sensor and the sensor should be checked. this is what the sensor looks like...it is located within the oven chamber(usually in the left side) to check it,it needs to unplugged and using a mulitmeter set to measure ohms,check the sensor to be between 1060-1100 ohms at room temp. if the sensor is way lower/higher that 1060-1100 at room temp the sensor is bad and needs to be replaced, if the sensor is within that range then the control board is the problem. GENE
When checking the sensor it shouls be checked at room temp (even if power off) at it should be between 1060-1100 ohms at room tempature. 16 ohms the new sensor is shorted the F2/F3/F4 all relate a faided sensor and the F5 error code says the clock (electronic oven control) is defective.
Test the sensor again at room temp...if only 16ohms its no good and will throw the F4 code everytime again a good sensor measured at room temp should be between 1060-1100 ohms
These are both problems with you Temperature sensor and circuit.
I would check the sensor first. You should have close to 1100 ohms. If this checks out good and wiring looks good the relay is integrated into the board so you would need to replace the control. The info below was taken from www.appliancehelponline.com You can also find diagrams there to show you what these parts look like. Open oven temperature sensor (circuit) (over 2700 ohms) or, shorted oven temperature sensor. Could be a result of: · contamination on terminals · pinched wire in oven temperature sensor circuit · cold solder joint on control. ·Disconnect power to range and remove oven temperature sensor connector from control. · Measure oven temperature sensor resistance at oven temperature sensor connector (take care not to damage terminals in block) - Should read 1100 ohms at room temperature (approx 72 degrees F). · Measure each oven temperature sensor lead from connector block to ground. If shorted, look for pinched or cut wire in oven temperature sensor circuit. · Check connector terminals - Look for deformed or corrosion on terminals. Repair or replace. If all above is ok replace control. F5 Relay safety circuit failure · Check oven temperature sensor circuit for intermittent high resistance. · Check lock circuit · Press Clear/Off and reprogram control. If code reappears, replace control
Note: If all above check OK the F5 code can be a result of a momentary loss of power (Do NOT replace control or lock, check lock circuit)
HI. This error code will occur when the control board senses an oven temperature above 915F-935F
Once this type of temperatures occur, this will generally weld the relay contacts on the main board. This will damage the board, and it will require you to have it replaced, asap. If these temperatures never reached the sated thresholds, i would advise to Look for a high resistance connection or any other cause of high resistance in the oven temperature sensor circuit. Check sensor, sensor harness and sensor harness connection at sensor and oven control. Replace the sensor if found to be defective. Check door lock switches for damage, as well.
In most cases, this will be a failed control board. To confirm, simply preform a resistance test on the sensor. The normal ohm readings should be 1100 ohms at room temperature.
If the oven temp sensor dose not test out at 1100 ohms at room temp, replace the sensor.
HI. this code is indicating that the oven temp sensor is malfunctioning. follow the steps below to address this issue further.
1. Look for welded relay contacts on bake or broil relays. If the relay contacts are welded, replace oven control (also called clock or ERC).
2. For SELF CLEAN models: check door lock operation.
3. Look for a high resistance connection or any other cause of high resistance in the oven temperature sensor circuit. Check sensor, sensor harness and sensor harness connection at sensor and oven control. Replace sensor if found defective.
Remember: Oven control (ERC) measures resistance of sensor circuit, not actual oven temperature.
The most common oven sensor should be approximately, 1100 ohms when at room temperature. The others may be close to as follows:
These are the F2/F3 error codes for a Tappan oven
Check Bake function, if OK, replace oven temperature sensor
temperature sensor open
oven temperature sensor, should
be ~1100 ohms at room temperature. If too high or low, replace
oven temperature sensor please take the time to give this solution a fix ya rating.
tire, if your model starts with 911. the code stands for an overtemperature condition. I would start with the temp sensor, this is the probe inside the oven cavity, part # 334300. You can ohm it out, should be around 1100 ohms at room temp. This is for model number starting with 911. Catriver..post back.
jaz3133, it's probably the temp sensor that has gone bad. You should be able to get it from the front. It's the probe that comes out from the back wall of the oven. You can have someone ohm it out. Should read approx 1100 ohms at room temp. Part number for the temp sensor is WB20K5040. Make sure power is off befor removing the sensor. Catriver..post back.
