The Goodman 20162903 Primary Limit Switch is a genuine OEM high-limit safety control engineered for the GCH950905DXAA gas furnace. This normally-closed switch continuously monitors heat-exchanger temperature and opens the burner circuit if the furnace exceeds its 150°F trip point, protecting the unit from overheating caused by restricted airflow, a dirty filter, or a failed blower. A tripped or failed limit switch is a common cause of short-cycling and no-heat calls.

Specifications

OEM Part Number: 20162903
Type: Primary high-limit (auto-reset)
Trip Temperature: 150°F
Application: Gas furnace heat exchanger / blower compartment
Fit: Direct replacement for GCH950905DXAA

OEM vs. Generic

Our OEM Goodman switch is calibrated to the exact trip point and mounting footprint your furnace's control logic expects. Generic universal limits often carry looser tolerances and require terminal or bracket adaptation, which can lead to nuisance trips. Choose OEM for guaranteed fit and factory-spec safety performance; choose generic only when a matching aftermarket limit is verified for your model.

Installation Difficulty

Easy (2/5). A two-wire swap for anyone comfortable working inside a furnace cabinet. Always shut off power and gas at the disconnect before servicing. If the original switch tripped, diagnose and correct the underlying airflow or blower fault before returning the unit to service.
