F2 Error but Sensor Checks at 1100 ohms

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?

Order a new sensor.

I did replace the sensor and it seemed to work, but I got an F2 again after a few weeks.

When oven reaches a temp of 350 it flashes F3

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!

Why kenmore oven code f-10 comes on when bake or broil is on

If your Kenmore unit's model number starts with 790, an F10 error means that the oven temperature sensor is seeing a runaway temperature reading. This could mean that the sensor or the "clock" (electronic control unit) is bad. (Sometimes it could be the element but usually you'll see that easily.)

Unplug the unit (or flip the circuit breaker to off) for about 30 minutes to reset the error. If it recurs, you'll need to do additional troubleshooting to determine the fault. Please add a comment with the complete model number of your oven/range for additional assistance. searspartsdirect.com will probably have a parts diagram and parts list for your oven or range.

I hope this helps.

EO F2 The oven will not start or stop. I can not get the oven to work but it will beep with this EO F2 message sometimes.

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. 11_3_2011_2_07_54_pm.jpgthis 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.

My oven displayed F5 then F3 code I believe after a nearby lightning strike, When installing new sensor with supplied wire nuts I found black marks on oven side connector. Immediate F4 error code when...

Hello,

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

I was gettin a F5 error andnow i get a F3 error

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)

Kenmore built-in oven set at bake tempature does not set just keeps rising got F2 code

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.

I have an F2 error what does that mean

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:

100°F - 1143 ohms
200°F - 1350 ohms
300°F - 1553 ohms
350°F - 1654 ohms
400°F - 1753 ohms
500°F - 1949 ohms

Oven showing F2 fault

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.

F2 Oven overheats

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.
