When your Kelvinator oven probe is not working, the meat thermometer may show an error, fail to read temperature, or remain inactive when plugged in. The most likely cause is a faulty meat probe. The probe's resistance should change as its temperature changes; if a multimeter shows an open circuit, replace the probe. If the oven probe and jack test good, the range control board may not be responding to the temperature signal and could need replacement. A defective door switch is another possibility because some Kelvinator oven thermometers work only when the door is closed and the switch signals the control board. Test the door switch for continuity when actuated. Also inspect the probe receptacle, or jack, for corrosion, dirt, damage, or loose contact, then replace it if necessary. Less commonly, the oven control board may be defective. These checks can help resolve an oven probe not working problem or a meat thermometer not working problem without replacing the entire range. Enter your Kelvinator model number to find the exact replacement meat probe, receptacle, door switch, or control board for your oven.
01 - Kelvinator 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 - Kelvinator 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.
