Description
The Enerco/Mr. Heater F273117 is a 12-inch finished thermocouple designed as a direct OEM replacement for compatible Mr. Heater and Enerco heating appliances. Thermocouples are a critical safety component in gas-fired heating equipment — they continuously sense the pilot flame and signal the gas valve to remain open, automatically shutting off gas flow if the pilot extinguishes to prevent unsafe gas buildup.

Why Replace Your Thermocouple?
A worn or failed thermocouple is one of the most common causes of pilot outage issues in gas appliances. If the pilot will not stay lit after holding the pilot button, the thermocouple is often the culprit. Replacing it with a genuine OEM part like the F273117 restores safe, reliable heater operation quickly and cost-effectively.
