When your Whirlpool oven probe is not working, the meat thermometer may show a probe error, fail to detect temperature, or remain blank even when the oven is heating. The most likely cause is a faulty meat probe. Its resistance should change as the probe temperature changes, and an open circuit on a multimeter means the probe needs replacement. If the probe tests good, check the control board, which monitors the food temperature through the probe jack. A failed board can prevent the oven thermometer from responding. Next, inspect the door switch, since some Whirlpool ovens require the door to be closed before the meat probe operates. Test the switch for electrical continuity when actuated and replace it if it fails. A dirty, corroded, or damaged probe receptacle can also prevent good contact, so clean or replace the receptacle as needed. Less commonly, the oven control board may be defective. Before ordering, enter your Whirlpool oven model number to find the exact replacement part for your appliance. Repair Clinic carries the correct meat probe, receptacle, door switch, control board, and oven control board for many Whirlpool range, stove, and oven models.
01 - Whirlpool 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 - Whirlpool 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.
