The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety switch engineered for the Goodman ACSH960704CXAA 96% AFUE gas furnace and compatible Goodman/Amana models. This normally-closed thermal limit monitors heat exchanger and plenum temperatures and shuts off the gas valve and burners if the furnace overheats — protecting the heat exchanger, blower, and your home from unsafe conditions.

OEM part number: 20162904
Brand: Goodman / Amana
Equipment: 96% AFUE gas furnace
Fits model: ACSH960704CXAA and related Goodman furnaces

OEM vs. Generic

This is a genuine Goodman OEM limit control calibrated to the exact trip temperature your furnace's control board and gas valve expect. Generic or universal limits often carry a different set point or mounting footprint, which can cause nuisance lockouts or, worse, fail to trip at the correct temperature. For a safety-critical part like a limit switch, OEM is strongly recommended.

Installation Difficulty

Moderate. Replacement requires shutting off gas and power, removing the burner-compartment panel, transferring the wiring connectors, and remounting the limit on the heat exchanger or blower deck. Most experienced DIYers can complete it in 20–30 minutes; if you are unsure about a safety component, have a licensed HVAC technician verify operation after install.

Always disconnect power and gas before servicing. Confirm fit by your furnace's full model and serial number.
