Copeland Comfort Control (White Rodgers) H06E-18 Thermocouple

The White Rodgers H06E-18 Thermocouple is a professional-grade 18-inch gas pilot safety component engineered for high-reliability heat sensing in residential and commercial HVAC systems. Designed as a universal thermocouple replacement, the H06E-18 features a heavy-duty stainless steel element that withstands high-temperature oxidation and provides consistent millivolt output to the gas valve. This model is a standard field-service solution for pilot burner troubleshooting, offering a 18" lead length that fits most atmospheric burner configurations. The Copeland Comfort Control H06E-18 kit includes universal adapter fittings (including push-in, nut, and clip-style), ensuring mechanical compatibility with a broad spectrum of gas-powered heating appliances and pilot assemblies. For technicians, the inclusion of clear instructions and individual protective packaging makes this an essential stock item for cold-weather service calls.

• Universal Compatibility: Includes multiple adapter clips and nuts to replace most OEM furnace thermocouples and water heater sensors.
• Enhanced Durability: The stainless steel element construction minimizes tip burnout and maintains signal integrity under constant thermal stress.
• Standardized Output: Optimized for 18-30 millivolt operation, ensuring reliable drop-out times for safety shut-off valves.
• Rapid Installation: Flexible 18-inch copper lead allows for easy routing through combustion chambers without kinking.

What is the typical millivolt output for the H06E-18?
This 18-inch thermocouple is designed to produce a standard 20 to 30 millivolt signal under an open circuit test, ensuring it can properly energize the power head within the gas control valve.

Does this kit work with LP (Propane) and Natural Gas?
Yes, the H06E-18 is a gas heating replacement part compatible with both Natural Gas and Liquid Propane pilot assemblies, provided the pilot flame is properly adjusted for impingement on the upper 1/2 to 3/8 inch of the tip.

Can I use an 18-inch thermocouple if the original was 12 inches?
Yes, as long as the excess lead is safely coiled and does not interfere with the burner flame or moving parts, the H06E-18 serves as a functional replacement for shorter leads.
