Is your Modern Maid oven meat thermometer not working? The meat probe is the most likely cause. The probe's resistance should change as its temperature changes, but an open circuit on a multimeter indicates a failed probe that needs replacement. A faulty range control board is the next likely problem, especially when the probe and probe jack test good but the oven does not display or respond to the temperature reading. A defective door switch can also prevent the oven thermometer from functioning because some models require the door to be closed before the control board monitors the probe. Test the switch for electrical continuity when actuated. Next, inspect the probe receptacle or jack for corrosion, damage, or poor contact, and clean or replace it if needed. The oven control board is another possible cause when the probe and receptacle work correctly but the display shows a probe error or does not register the temperature. Before ordering an oven probe, door switch, receptacle, or control board, enter your Modern Maid oven model number to find the exact replacement part for your specific range, stove, or oven.
01 - Modern Maid 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 - Modern Maid 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.
