Question and Answers

Q:

FRIGIDAIRE (FGF366BCB) oven: preheat stays on-oven feels hot , but takes a very long time to bake

A:

You could have a problem with the bake igniter that is preventing the bake burner to start properly. A problem with the oven temperature sensor problem could also cause this problem. An intermittent problem can be difficult to diagnose.

Check to see if the broiler works properly. If the broiler works good then your likely problem is with the igniter on the bake burner.

I recommend that you get an oven thermometer and determine the temperature that the oven is heating up to. If the oven consistently heats to a temperature that is less than the set temperature and continues to maintain this lower temperature then you could have a bad temperature sensor. You can check the temperature sensor by measuring the resistance through this component. Check to see if there are screws in the back inside wall of the oven that secure the probe. If there are, you can unplug the oven and remove these screws. Carefully pull the sensor probe into the oven cavity until you encounter the wire harness disconnect plug. Unplug the probe. Measure the resistance through the sensor probe using a volt/ohm meter. At room temperature, the sensor probe should measure about 1100 ohms of resistance. If it is more than 20 ohms lower than that, I recommend that you replace the oven temperature sensor probe. The part number for the probe is 316233902. You can order this part from the Sears PartsDirect website.

If the temperature sensor is okay, you could have a problem with the igniter. If the burner initially ignites and heats and then shuts off or takes a long time to re-ignite, then you will likely need to replace the igniter (part 5303935066). Even through the igniter is glowing, the resistance through this component may not be decreasing enough to allow the proper amps through the circuit to open the gas valve.

Q:

Why won't my Frigidaire oven control temperature within 50 degrees above or below the set temperature?

A:

Before making any adjustments, I recommend accurate measuring the oven temperature according to the manufacturer's directions. An accurate measure of oven temperature can only be taking by using a precision thermocouple thermometer. The oven must be allowed to preheat and then cycle at least five times. An average temperature measurement over a 10 minute period of time would provide an accurate indication of the oven temperature.

If the difference in temperature is a consistent difference that has been accurately measured, you can adjust the oven temperature up to 35 degrees using the oven control. This procedure is shown in the first image below.

If the difference in temperature varies between 50 degrees above and below the set temperature using the measurement method described above, then you could have a bad oven temperature sensor or a failed electronic oven control board.

The control board detects the oven temperature by monitoring the resistance of the oven temperature sensor probe. This probe protrudes through the back wall of the oven. If you are able to access this probe and unplug it, you can check the resistance using a volt/ohm meter. At room temperature, you should measure near 1100 ohms of resistance. The temperature resistance chart for this component is shown in the second image below. If the resistance of this temperature sensor probe is way off, then it will need to be replaced.

If the temperature sensor resistance is normal, then you may have a failed control board or a wire harness failure between the sensor and the control board. If you need more help, resubmit your question with additional details.
