When your Kenmore oven meat thermometer is not working, the meat probe is the most likely cause. The probe changes resistance as its temperature changes, and an open circuit when tested with a multimeter means the probe has failed and needs replacement. If the probe tests good, check the probe jack or receptacle for corrosion, damage, dirt, or poor contact. The Kenmore oven control board monitors the food temperature through this connection, so a faulty control board can also cause an oven probe not working problem. Some Kenmore ovens require the door to be closed before the meat thermometer operates. A defective door switch may prevent the control board from recognizing that the door is shut, so test the switch for continuity while actuated. Less commonly, the oven control board itself may be defective. Disconnect power before testing or replacing parts, and follow proper multimeter safety procedures. Enter your Kenmore oven model number to find the exact replacement meat probe, receptacle, door switch, or control board for your range, stove, or oven.
01 - Kenmore 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.
