If your Hotpoint oven probe is not working, the meat thermometer may show no temperature, an incorrect reading, or a probe error. Start with the meat probe, the most likely cause. Its resistance changes as temperature changes, so test it with a multimeter and replace the probe if it shows an open circuit. If the probe tests good, inspect the probe jack, also called the receptacle, for corrosion, damage, or poor contact. The control board monitors the probe through this connection and may be faulty if it does not respond. A defective door switch can also prevent the oven probe from working because some Hotpoint ovens require the door to be closed before the meat thermometer operates. Test the switch for continuity when actuated. Less commonly, the oven control board or a damaged wire connection may be the problem. Before ordering an oven probe, receptacle, door switch, or control board, enter your Hotpoint range, stove, or oven model number to find the exact replacement part for your appliance.
01 - Hotpoint 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.
