Axis 117-0039 Thermopile

Product Description

The AXIS 117-0039 is a thermopile sensor used in commercial gas appliance applications. A thermopile generates a small DC voltage from the temperature difference across its junctions, providing the millivolt signal that powers and regulates a standing-pilot gas control valve. Unlike a standard thermocouple, a thermopile produces enough output voltage to operate the gas valve directly without requiring external power. This part is installed by licensed commercial appliance technicians or qualified HVAC-R service professionals during routine maintenance or pilot-system failure diagnosis.

The 117-0039 is designed for use in AXIS commercial appliance systems. Thermopiles of this type are commonly found in commercial cooking equipment, water heaters, and other standing-pilot gas appliances where a self-powered millivolt control system is required. Service technicians typically encounter this part during no-heat or pilot-outage calls where the gas valve fails to open or remain open despite a lit pilot flame.

Key Features

• Generates millivolt DC output from pilot flame heat to power gas control valve
• Designed for standing-pilot gas control systems in commercial appliances
• OEM AXIS part number 117-0039 ensures direct fit for applicable equipment
• Replaces a failed thermopile without requiring gas valve replacement in most cases

Compatibility

Designed as an OEM replacement thermopile for AXIS commercial appliance equipment. Consult equipment documentation to confirm fitment before ordering.

Installation Notes

Installation should be performed by a licensed technician qualified to service commercial gas appliances. Shut off the gas supply and allow all components to cool completely before removing the existing thermopile. Secure the replacement thermopile lead connection to the gas valve terminal per the appliance manufacturer specifications, and verify millivolt output at the gas valve terminals after relighting the pilot to confirm proper operation. Work must comply with applicable local codes and the appliance manufacturer service guidelines.
