Ferguson Enterprises 20162906 Primary Limit Switch

Product Description

The FERGUSON ENTERPRISES 20162906 is a primary limit switch designed for use in gas furnace systems. The primary limit switch is a critical safety component that monitors heat exchanger temperature and interrupts the burner circuit when the furnace reaches an unsafe operating temperature. This prevents overheating damage to the heat exchanger and surrounding components. Licensed HVAC technicians typically install and replace this component as part of routine furnace service or in response to nuisance tripping caused by airflow restrictions or blower failures.

This primary limit switch is suited for residential gas furnace applications where the OEM limit switch has failed or requires replacement. It is referenced under Goodman and Amana furnace product lines based on the supplier-provided title. Install this switch in systems experiencing limit lockout conditions or as a preventive replacement during heat exchanger service. Its compact form factor fits in standard limit mounting locations found in upflow, downflow, and horizontal furnace configurations.

Key Features

• Safety shutoff function interrupts burner operation on over-temperature condition
• OEM-style replacement for Goodman and Amana furnace primary limit circuit
• Designed for gas furnace heat exchanger temperature monitoring
• Direct swap for failed or nuisance-tripping primary limit switches

Compatibility

Referenced as a Goodman and Amana replacement primary limit switch based on supplier-provided data. No specific model numbers or system families were provided in the input. Verify compatibility against the OEM part number on the original switch before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect power to the furnace at the disconnect switch or breaker and shut off the gas supply before replacing the primary limit switch. Inspect the blower motor, filter, and ductwork for restrictions that may have caused the original limit to trip before installing the replacement. Follow local mechanical codes and the furnace manufacturer service documentation for mounting orientation and wiring procedures.
