Johnson Controls K16BA-36d Thermocouple Husky 36 in

Product Description

The Johnson Controls K16BA-36d is a Husky-series coaxial thermocouple designed for use in gas-fired heating systems. A thermocouple generates a small millivolt signal from the heat of a standing pilot flame, holding open the gas valve as long as the pilot stays lit. If the pilot extinguishes, the signal drops and the valve closes automatically, providing a critical safety shutoff function. The K16BA-36d features a 36-inch coaxial lead, giving technicians adequate working length for routing from the pilot assembly to the gas valve without splicing or stressing the connection.

This thermocouple is suited for residential and light commercial gas appliances including furnaces, boilers, water heaters, and floor furnaces that use a standing pilot ignition system. The coaxial construction keeps the inner and outer conductors in precise alignment, which helps maintain consistent signal output over the service life of the component. It is typically installed by licensed HVAC technicians or plumbers during routine pilot-system service, thermocouple replacement, or gas valve troubleshooting.

Key Features

• 36-inch coaxial lead provides generous routing length between pilot assembly and gas valve
• Husky-series construction for reliable millivolt output under continuous pilot flame exposure
• Coaxial design maintains conductor alignment for consistent signal integrity
• Direct replacement form factor simplifies field swap-out without special tools
• Compatible with standard gas valve thermocouple connections used across common appliance types

Compatibility

Designed as an OEM-style replacement thermocouple for standing-pilot gas appliances including furnaces, boilers, and water heaters. The input also references Johnson Controls part number 511425 as an associated cross-reference for this component.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and applicable local gas codes. Shut off the gas supply at the appliance service valve before removing the existing thermocouple. Hand-tighten the fitting at the gas valve first, then snug with a wrench - do not overtighten, as thermocouple fittings are brass and can strip easily. Confirm pilot flame engulfs the thermocouple tip fully before returning the appliance to service.
