Tappan Oven meat thermometer not working
When your Tappan oven meat thermometer is not working, the meat probe is the most likely cause. The probe's resistance should change as its temperature changes, but an open circuit on a multimeter indicates a failed probe that needs replacement. If the probe tests good, the control board may not be detecting its temperature signal through the probe jack. Next, check the door switch, since some Tappan ovens require the door to be fully closed before the oven probe will operate. Test the switch for electrical continuity when activated, and replace it if it fails the test. A dirty, corroded, or damaged receptacle can also prevent the probe from making reliable contact, so inspect and clean the jack before replacing it. If the probe, receptacle, and door switch are working, the oven control board may be faulty and unable to read the probe. These checks address common oven probe not working, meat thermometer not working, and oven probe error problems. Always disconnect power before testing components, and enter your Tappan oven's model number to find the exact replacement part for your specific appliance.

Highly Likely
02 - Tappan Range/Stove/Oven Control Board
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.
Common
03 - Tappan Range/Stove/Oven Door Switch
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.
Uncommon But Possible
04 - Tappan Range/Stove/Oven Receptacle
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.
Uncommon But Possible
05 - Tappan 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.
Uncommon But Possible
