The Goodman 20162903 Primary Limit Switch is a genuine OEM 150°F high-limit control for the AMH951155DXAG 95% AFUE gas furnace and compatible Goodman/Amana models. Mounted on the heat-exchanger bulkhead, this automatic-reset switch monitors supply-air temperature and interrupts the gas valve if the plenum overheats — typically from a dirty filter, blocked ductwork, or failed blower. It restores automatically once temperatures return to a safe range.

  • Trip point: 150°F (opens on rise)
  • Reset type: Automatic (self-resetting)
  • Function: Primary high-limit safety cutout
  • Fits: AMH951155DXAG and compatible Goodman & Amana furnaces
  • Terminals: 1/4" quick-connect spade

OEM vs. Generic: The 20162903 is calibrated to the precise 150°F trip point and disc diameter the furnace control sequence relies on. Generic switches with a nearby rating can trip early (short cycling) or late (no protection). For a listed safety device, the OEM part guarantees correct calibration and a factory mounting fit.

Install difficulty: Easy — 15 to 30 minutes. Cut power, remove the two mounting screws, transfer the spade wires, and mount the replacement flush against the heat exchanger. Confirm normal cycling and supply-air temperatures after service.

Is this limit switch compatible with Bryant or Payne too?
