Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 is a genuine OEM primary high-limit temperature control engineered for the Amana/Goodman AMH950904CXAC gas furnace and compatible 95%-efficiency models. This normally-closed thermal safety switch monitors heat-exchanger supply-air temperature and cuts power to the gas valve if the furnace overheats — protecting the heat exchanger, blower, and your home from unsafe operation. A failed limit control is a common cause of short-cycling, no-heat lockouts, and repeated flame roll-out faults.

Specifications

Part type: Primary limit / high-limit temperature control
Contact configuration: Normally closed (opens on temperature rise)
Fits: AMH950904CXAC and compatible Goodman/Amana furnaces
OEM replacement for part number 20162904
Auto-reset thermal disc design

OEM vs. Generic

Our OEM option is the exact factory-specified control with the correct trip temperature and mounting footprint — the safest choice for a like-for-like repair. The generic equivalent meets the same electrical and temperature ratings at a lower price point and is ideal for budget-conscious repairs where an exact factory match is not required. Both carry the same normally-closed safety function.

Installation Difficulty

Moderate (2/5). Replacement takes most DIYers 15–20 minutes with a nut driver and slip-on spade connectors. Always shut off gas and power at the furnace before servicing. If you are unsure about correct trip-point matching or safety wiring, consult a licensed HVAC technician.
