When I turn on the oven it won't stay on. The cpu timer will beep and give a F3 error message. I already replaced the cpu, that was not it. I think it's the sensor 12001655. Can you confirm or is there another area I should look at? Thank you Hi I have a Kenmore wall gas oven model 790.30179400 and the only concern is that it beeps all the time.There is no error codes and all oven functions are fine.It is just the "beeping"Any help on this besides being a module concern.Thank You.Email is [email protected] again

Disconnect the power. Disconnect the sensor harness from the control. Measure the sensor resistance (white leads). The resistance should be 1080 ohms at room temp. If the sensor is open the resistance is usually over 2900 and you get an F3 message. If the sensor is shorted the resistance is usually less than 950 ohms and you get an F4 error message. Also look for damaged harness terminals if not a bad sensor.

Here is some wisdom for understanding F1 fault codes.
In some models, there are subcodes that make diagnosis even easier.
Here's a simple explanation of what's going on and how to troubleshoot:
The F1 code indicates that:
a. The electronic range control (ERC) is sensing heat in the oven when in a time-of-day (i.e., not cooking) mode.
b. The ERC is receiving information to run multiple heat functions simultaneously.
Although different components (depending upon the model) could generate the code, simple and straightforward testing using your ohm meter is all you gotta do to test for it.
1. Check the oven temperature sensor. The oven sensor has to be within spec or it will cause the F1 code.
As an example of being out-of-spec, the ERC will generate an F1 fault code when the sensor shows 1650 ohms during a time-of-day mode.
This is equivalent to 350°F in the oven.
The resistance isn't high enough to generate an F2 code (runaway temp) or an F3 or F4 code (shorted/open sensor circuit).
The ERC monitors the sensor circuit after a heat cycle and expects the resistance to drop back to 1050-1100 ohms.
The fault code is generated when this doesn't happen. Checking the sensor circuit means also checking the harness,
harness connections and the sensor itself.
2. If the oven sensor circuit checks okay, then turn your inquisitive eyeballs to the touchpad.
If the range has a separate touchpad/keyboard, the keypad may have moisture that is shorting several circuits simultaneously.
If the F1 code is given immediately (instead of during or after a heat cycle),
remove the ribbon connector from the touchpad to the ERC after clearing the F1 code. If the F1 code does not return in five minutes,
then cast a suspicious gaze upon the touchpad/keyboard. Shorts may be caused by using an ammonia-based glass cleaner.
The touchpad surface will absorb ammonia-based cleaners that are sprayed directly on the glass surface. When heat is applied,
the surface material can break down causing shorts.
If you're gonna use ammonia-based cleaners on your control panel, then you should spray it on the rag and then wipe the touchpanel
-don't spray directly onto the surface of the touchpad.
3. On Amana ranges with a rotary temperature dial, be sure that the knob is in the OFF position when performing tests.
4. If these tests all check good, then replace the ERC.
