Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 primary limit switch is a genuine OEM safety high-limit control engineered for the Amana/Goodman AMVC80704BXAA two-stage variable-speed gas furnace and compatible models. This normally-closed thermal switch opens at approximately 150°F to shut down the burners if the heat exchanger overheats, protecting your furnace, ductwork, and home from unsafe operating temperatures. A failed or drifting limit switch is a common cause of intermittent lockouts, short cycling, and no-heat calls.

Specifications

Part number: 20162903
Function: Primary high-limit safety switch
Open temperature: 150°F (auto-reset)
Contact type: Normally closed (SPST)
Brand fit: Goodman / Amana furnaces
Primary model: AMVC80704BXAA

OEM vs. Generic

Our OEM Goodman switch is calibrated to the exact trip temperature and mounting footprint the control board expects, ensuring reliable safety response and correct staging. Aftermarket generics may open at slightly different temperatures or use looser tolerances, risking nuisance trips or delayed shutdown. For a factory-matched fit and full furnace-board compatibility, we recommend the genuine OEM part.

Installation Difficulty

Easy (1 of 5). Replacement is typically a two-wire, single-fastener swap on the burner/heat-exchanger assembly. Always disconnect power at the furnace switch and breaker before servicing. If your furnace repeatedly trips on limit, also inspect the blower, filter, and airflow — a chronically open limit is often a symptom of restricted airflow, not a bad switch.

Backed by genuine OEM quality for dependable, safe furnace heating all season long.
