Ensure reliable defrost cycle performance with the Lennox 47K19 (36327B006) Defrost Tube Thermostat. Engineered for precision, this thermostat is designed to monitor and control the temperature on refrigeration or HVAC system tubing to activate and deactivate the defrost cycle as needed.
With a 3/8" diameter tube mount, it securely clamps to refrigerant lines for accurate temperature sensing. The thermostat closes at 32°F, signaling the system to begin defrosting when ice formation is likely, and opens at 55°F, ending the defrost cycle once the temperature rises to a safe level—helping prevent overheating and unnecessary energy consumption.
