I have a frigidaire built-in oven model CFEB786JGB3. I changed the oven probe but still get an F-3 error

Part F161 is the Convection Element. Check it for continuity with a multimeter and also check the connection tags to it as they can melt.

A faulty RTD sensor probe is one of the causes for an F10 code or overheating oven. The sensor probe is supposed to detect the exact temperature in the Frigidaire electric range cavity and relay it to the oven's main control so it knows when to shut off the heating elements. Follow your wiring diagram to find the probe's location, which can differ among the models. Inspect it for any obvious damage such as cracks or tears in the wiring.

It looks like the probe is the same as the temperature sensor.

On some models, you can recalibrate the oven control up to 35 degrees Fahrenheit higher or lower. Refer to your owner's manual for instructions on how to recalibrate the oven control.

Since you're getting an error message the following may apply:

OPEN PROBE CONNECTION
1. (F30 or F31) Check resistance at room temperature & compare to RTD Sensor resistance chart. If resistance does not match the RTD chart replace RTD Sensor Probe. Check Sensor wiring harness between EOC & Sensor Probe connector.

SHORTED PROBE CONNECTION
2. (F30 or F31) Check resistance at room temperature, if less than 500 ohms, replace RTD Sensor Probe. Check for shorted Sensor Probe harness between EOC & Probe connector. .

Hi - Typically error code F3 indicates a faulty sensor probe or wiring harness between sensor probe and EOC. Try resetting the range by unplugging it or flipping the circuit breaker off for two minutes (this usually will clear most false error codes). Turn on the range and if resetting the unit proves to be ineffective, I would recommend contacting a professional to move forward accurately.

Hi - Typically error code F30 for Frigidaire range indicates an issue with the sensor probe or the wiring harness between sensor probe and EOC. If you have already changed the sensor, I suggest checking the wiring or contacting a professional to move forward accurately. You can try resetting the unit and see if the error code will clear. You can either unplug the unit or flip the household circuit breaker off. Wait approximately ten minutes and turn on the range. If issue continues, once again contact a professional to properly diagnose the unit.

No the Probe is usually a device with a lead that you stick into the thing your cooking to check temperature. The Sensor, is usually built in somewhere.

Part #37 on diagram #3 will show the temperature probe that needs replacing.

f1 is a watchdog on the control board
replace control

The F30 error code indicates that the electronic oven control board detects an "open" oven temperature sensor probe circuit.
This is usually caused by a failed oven temperature sensor probe.

Replacing this component will likely fix your problem.

You can order this part from www.searspartsdirect.com website.

If you replace this part yourself, be sure that you unplug the range to disconnect electrical power before accessing this component.

On some models, you can replace the probe by removing the screws that mount this component to the inside back wall of the oven.
Carefully pull the probe inside the oven cavity until you encounter the wire harness disconnect plug.
Unplug the sensor and replace it with the new one. Mount the new probe on the back wall of the oven.

On some models, you have to remove the lower back oven panel to access the sensor probe.

If you replace the probe and still have this problem, you will need to unplug the range and measure the resistance through the violet wires that plug into the control board (this is where the sensor probe circuit is connected to the control board).
If the resistance through the oven temperature sensor probe circuit is normal (about 1100 ohms at room temperature) then the electronic oven control board will need to be replaced.
