When your Estate oven meat thermometer is not working, the oven probe is the most likely cause. A damaged probe may show an open circuit when tested with a multimeter, so replace the meat probe if it does not have the proper resistance for the temperature. If the probe tests good, check the Estate range control board, which reads the probe's resistance through the probe jack and displays the food temperature. A faulty door switch can also prevent the oven thermometer from working because some models require the door to be closed before the control board accepts a probe signal. Next, inspect the probe receptacle for corrosion, damage, or a loose connection that keeps the probe from making contact. Less commonly, the oven control board may have failed. These checks apply whether you are searching for an oven probe not working, a meat thermometer not working, or an oven probe error. Disconnect power before testing electrical parts, and use a multimeter when required. Enter your Estate range, stove, or oven model number to find the exact replacement probe, control board, door switch, or receptacle for your appliance.
01 - Estate 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.
