OEM Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 is a genuine OEM primary limit temperature control for the AMH950904CXAE gas furnace and compatible Goodman/Amana models. Positioned over the heat exchanger, this high-limit switch continuously monitors supply-air temperature and opens the burner circuit if the furnace overheats — typically due to restricted airflow from a dirty filter, blocked ducting, or a failing blower. Unlike the manual reset rollout switches, the primary limit is an automatically resetting control that closes again once temperatures return to a safe range, allowing normal operation to resume.

Specifications

Type: Primary high-limit temperature control (auto reset)
Function: Opens burner circuit on over-temperature, auto-resets on cooldown
Location: Heat-exchanger / supply-air limit
Fits: Goodman & Amana furnaces including AMH950904CXAE
OEM Part Number: 20162904

OEM vs. Generic

OEM 20162904 is calibrated to the precise trip and reset temperatures Goodman engineered for this furnace, with the correct mounting bracket and insertion depth. Generic high-limits can vary in calibration and probe length, risking nuisance shutdowns or delayed protection. For the furnace's primary safety limit, the OEM control is the right choice.

Install Difficulty

Easy (2 of 5). Turn off gas and electrical power, remove two mounting screws and the wire leads, and install the replacement in the same orientation. If the limit keeps tripping, diagnose airflow (filter, blower, ductwork) before returning the furnace to service.
