When your JC Penney oven meat thermometer is not working, the meat probe is the most likely cause. The probe changes resistance as the food temperature changes, and an open circuit on a multimeter indicates that the probe needs replacement. A failed probe can cause an oven probe error or make the temp probe not work even when the oven itself heats normally. If the probe tests good, the range/stove/oven control board may not be reading its signal, especially when the probe jack is connected. Next, check the oven door switch, since some JC Penney ovens require the switch to confirm that the door is closed before the oven thermometer operates. Test the switch for continuity when actuated. A dirty, corroded, or damaged probe receptacle can also prevent proper contact, while an oven control board problem is less common but possible. Before ordering an oven probe, meat thermometer, receptacle, door switch, or control board, enter your model number to find the exact replacement part for your specific JC Penney range, stove, or oven.
01 - JC Penney 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 - JC Penney 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.
