If your GE oven meat thermometer is not working, the meat probe is the most likely cause. The probe's resistance changes as its temperature changes, so test it with a multimeter. An open circuit means the probe is defective and needs replacement. If the probe tests good, inspect the probe jack, also called the receptacle, for corrosion, damage, or poor contact, and make sure it is clean and firmly connecting with the probe. A defective control board can also cause an oven probe not working problem because the board monitors the food temperature through the receptacle. Some GE ovens will not operate the oven thermometer unless the door is closed, so test the door switch for electrical continuity when actuated and replace it if it does not function correctly. Less commonly, the oven control board or its wiring may be at fault if the probe and receptacle are good but the display shows a probe error or does not respond. Enter your GE range, stove, or oven model number to find the exact replacement meat probe, receptacle, door switch, or control board for your appliance.
01 - GE 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.
