White-rodgers h06e018s1 Thermocouple 18 in Standing Pilot

Product Description

The WHITE-RODGERS h06e018s1 is an 18-inch replacement thermocouple designed for standing pilot gas heating systems. It joins two dissimilar metals to generate a small millivolt signal, between 18 and 30 mV, that the ignition control system uses to verify the pilot flame is present and stable. The stainless steel element and threaded process connection make it a durable, field-ready part. A universal adapter fitting is included, so technicians can complete most swap-outs without sourcing additional hardware. HVAC service techs and gas appliance technicians are the primary installers of this component.

This thermocouple is suited for residential and light commercial gas appliances that use standing pilot ignition. It is compatible with LP and natural gas fuel systems. Compatible series include the 1980, H06E, K19, and Q34A. This part is a direct replacement for OEM thermocouples originally supplied by Honeywell, Johnson, Robershaw, and White-Rodgers, covering a wide range of legacy standing pilot equipment still in active service.

Key Features

• 18-inch cable length provides reach in standard appliance configurations
• Output range of 18 to 30 mV compatible with typical millivolt ignition controls
• Stainless steel element construction for durability at elevated temperatures
• Threaded process connection with 11/32-inch connection size for secure installation
• Universal adapter fitting included for broad fitment without extra parts
• Compatible with LP and natural gas fuel types

Compatibility

Compatible with the 1980, H06E, K19, and Q34A series. Serves as a replacement for OEM thermocouples from Honeywell, Johnson, Robershaw, and White-Rodgers on standing pilot gas appliances.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified gas appliance service professional. Shut off the gas supply and allow the appliance to cool completely before removing the existing thermocouple. The threaded connection should be hand-tightened and then snugged with a wrench to ensure a gas-tight fit without over-torquing the soft seat. Always verify pilot flame operation and millivolt output after installation before returning the appliance to service.
