Thermostat WP4-83053-002

Hello Frank, thank you for the question. According to our research, you can use a multimeter and ice water to test the thermostat for electrical continuity. Place the thermostat sensing bulb in the ice water and attach the probes to the thermostat terminals. Rotate the dial. As the dial reaches the lower setting, continuity in the thermostat should be interrupted. If the thermostat tests negative for continuity at all settings, then it's likely the component is defective and you will need to replace it. We hope this helps!
