If your RCA oven probe is not working, the meat thermometer may show no temperature, an incorrect reading, or a probe error. The most likely cause is a defective RCA range, stove, or oven meat probe. Its resistance should change as the probe heats, and an open circuit reading with a multimeter means the probe needs replacement. If the probe is good, inspect the probe jack or receptacle for corrosion, dirt, or damaged contacts that prevent a solid connection. The control board monitors the food temperature through this receptacle, so a failed range control board or oven control board can also cause the oven probe not to work. Less commonly, a faulty door switch may prevent the meat thermometer from operating when the oven door is closed. Test the switch for electrical continuity while it is actuated, and replace it if it fails the test.

01 - RCA 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.
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.
