Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 is the primary high-limit safety switch for the GCH950704CXAC gas furnace and compatible Goodman/Amana models. Mounted on the heat exchanger or in the supply plenum, this control continuously monitors furnace temperature and interrupts the burner circuit if heat exceeds a safe threshold — the key protection against a failed blower, dirty filter, or restricted duct causing the heat exchanger to overheat. A furnace that heats briefly then shuts off on limit, or fails to fire at all, often points to a tripped or failed limit control.

Function: Primary high-temperature safety cutout
Type: Automatic-reset snap-disc limit switch
Fits model: GCH950704CXAC and cross-referenced Goodman/Amana furnaces
Circuit: Normally closed; opens on over-temperature
OEM part number: 20162904

OEM vs. Generic

Limit switches are calibrated to a precise trip temperature and mounting-hole pattern for each furnace. Installing the exact OEM 20162904 guarantees the correct set point — a generic switch with the wrong temperature rating either nuisance-trips or, worse, fails to protect the heat exchanger. For a safety device, always use OEM.

Installation Difficulty

Moderate. Requires removing two mounting screws and transferring the wire terminals to the new switch. Cut all power at the disconnect first. If the old limit tripped, diagnose and correct the underlying airflow restriction (filter, blower, ductwork) before returning the furnace to service.
