Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 primary limit temperature control is a genuine OEM safety component engineered for the AMSS961205DNAA gas furnace and compatible Goodman/Amana models. This high-limit switch continuously monitors heat-exchanger temperature and interrupts the gas valve and ignition sequence if the furnace overheats, protecting your equipment and home from unsafe operating conditions. Because it is an exact factory replacement, it drops into the original mounting location with no modification.

Specifications

  • Part type: Primary high-limit temperature control
  • Function: Overheat / heat-exchanger safety cutout
  • Fits model: AMSS961205DNAA (Goodman/Amana furnaces)

OEM vs. Generic

The genuine OEM 20162904 is factory-calibrated to the precise trip temperature specified for your furnace, ensuring correct safety response. Generic substitutes may use approximate temperature ratings that can cause nuisance shutdowns or fail to protect the heat exchanger. For a critical safety control, we recommend the OEM part.

Install Difficulty

Easy (1 wrench). Two screws and two spade connectors — a typical replacement takes 10–15 minutes. Always cut power at the disconnect before servicing.
