If your Frigidaire oven probe is not working, the meat thermometer may show no temperature, display a probe error, or fail to respond when connected. The most likely cause is a defective meat probe. Its resistance should change as the probe temperature changes, and an open circuit reading on a multimeter means the probe needs replacement. If the probe tests good, the control board may not be reading it correctly. Next, check the door switch, since some Frigidaire oven thermometers work only when the oven door is closed and the switch signals the control board. Test the switch for electrical continuity when actuated, and replace it if it fails. A dirty, corroded, or damaged probe receptacle can also prevent good contact, causing an oven probe not working or meat thermometer not working symptom. Finally, the oven control board may be faulty if the probe and receptacle are good but the temperature is not detected. Before ordering an oven probe, receptacle, door switch, or control board, enter your model number to find the exact replacement part for your specific Frigidaire oven.
01 - Frigidaire Range/Stove/Oven Meat Probe
The meat probe resistance changes with the temperature of the probe. If the probe shows an open circuit when tested with a multimeter, the probe is bad and will need to be replaced.

When the probe is plugged into the jack, the control board monitors the food temperature from the probe. If the temperature probe and jack are good but the control board is not responding, the control board is likely bad.
Some oven meat thermometers will not function properly unless the oven door is closed which activates a door switch to alert the control board that the door is closed. If the door switch is defective, the oven meat thermometer may not work. To determine if the switch is defective, use a multimeter to test it for electrical continuity when actuated. If the door switch does test appropriately for continuity, replace it.
The meat probe jack or receptacle needs to be clean and making good contact with the meat probe. If the receptacle appears corroded or damaged, the component should be replaced.
05 - Frigidaire Range/Stove/Oven Oven Control Board
When the probe is plugged into the jack, the oven control board monitors the food temperature from the probe. If the temperature probe and jack are good but the control board is not responding, the control board is likely bad.
