The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM safety switch for the AMH950453BXAC gas furnace. Mounted on the heat-exchanger/blower deck, it monitors supply-air temperature and opens the gas/ignition circuit if the furnace overheats — protecting the heat exchanger from cracking and preventing an unsafe operating condition. A failed limit is a leading cause of a furnace that short-cycles, blows cold air, or won't fire at all.

Part number: 20162904 (OEM Goodman/Amana)
Type: Auto-reset primary high-limit control
Function: Opens burner circuit on over-temperature
Mounting: Factory bracket on the blower/heat-exchanger panel
Fits: AMH950453BXAC 95% AFUE furnaces

OEM vs. Generic: A limit switch is a life-safety device — its trip and reset temperatures must match the furnace's design. Generic limits with the wrong set point either nuisance-trip on normal operation or, worse, fail to trip when they should. This OEM control is calibrated to Goodman's exact cut-out temperature and uses the correct sensing-element length and bracket for an exact fit.

Install difficulty: Moderate (2/5). Cut power at the breaker, remove the two mounting screws, transfer the wire leads to the new switch, and reinstall. Basic wiring knowledge required. Verify correct operation on restart.
