When your Roper oven probe is not working, the meat thermometer may show no temperature, display a probe error, or fail to respond when you plug it in. The most likely cause is a defective meat probe. The probe's resistance changes as its temperature changes, so test it with a multimeter and replace it if it shows an open circuit. If the probe is good, the range control board may not be reading the signal from the probe jack. A damaged, corroded, or dirty receptacle can also prevent proper contact. Some Roper ovens require the door to be closed before the oven probe operates, so test the door switch for continuity when actuated and replace it if it fails. If the probe, receptacle, and door switch test properly, a faulty oven control board may be causing the problem. These checks apply whether you're searching for an oven probe not working, a meat thermometer not working, or a temp probe not working solution. Enter your Roper range model number to find the exact replacement probe, receptacle, door switch, or control board for your appliance.
01 - Roper 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.
