White-Rodgers thermocouple, 24 in stainless steel probe with threaded fitting

Emerson Climate Technologies

Emerson Climate Technologies WHITE-RODGERS H06E024S1 Thermocouple 24 in 18 to 30 mV

SKU CH-1NRN-W291N

Replacement thermocouple for standing-pilot systems, 24 in cable, 18 to 30 mV output, stainless-steel element with universal adapter fitting

  • Universal adapter simplifies installation on varied pilot systems
  • 24-inch cable length fits standard standing-pilot assemblies
  • 18 to 30 mV output matches common gas-valve requirements
  • Stainless-steel element resists corrosion in LP and NG service
  • Threaded 11/32-inch connection ensures secure, leak-free fit

Pilot-system replacement

This WHITE-RODGERS thermocouple replaces a worn sensor in a standing-pilot gas appliance. It supplies an 18 to 30 mV signal to keep the gas valve open when the pilot flame is present. The 24 in stainless-steel element resists corrosion in LP or natural-gas service. Installers use it when the original probe no longer generates reliable voltage.

Universal adapter fitting

The threaded 11/32 in process connection accepts the included universal adapter, letting the probe fit a wider range of pilot brackets without re-threading. This flexibility is worth the swap when the old coupling size is non-standard or damaged. The adapter threads on in seconds, reducing downtime during a service call. No special tools are required for the changeover.

Stainless-steel element in a build

The probe mounts directly into the pilot assembly and routes its 24 in cable to the gas valve terminals. Stainless-steel construction withstands continuous flame exposure without degrading. The assembly frees the technician from fabricating a custom-length lead. Buyers who need a longer reach or a different voltage range will need a different model.

Questions about this item

What thread size does the 11/32 in process connection require for mounting?

The thermocouple uses an 11/32 in threaded process connection and includes a universal adapter fitting for installation.

How do you install the standing pilot thermocouple without damaging the 18 to 30 mV output element?

Thread the 11/32 in connection into the pilot assembly, attach the universal adapter, then tighten by hand plus one quarter turn with a wrench to avoid crushing the stainless steel element.

When should the 24 in stainless steel thermocouple be replaced in a standing pilot system?

Replace it when the pilot flame no longer holds or the millivolt output drops below 18 mV, indicating the element has degraded.
