The Goodman 20162901 Primary Limit Switch is a genuine OEM safety control for the ADSH801005CXAB gas furnace and compatible Goodman/Amana models. Mounted on the heat exchanger or blower housing, this thermally-activated high-limit switch monitors supply-air temperature and cuts power to the gas valve if the furnace overheats — protecting the heat exchanger and preventing a fire hazard. A failed limit switch is a leading cause of short-cycling, no-heat calls, and lockout codes.

Specifications

Function: Primary high-temperature limit / safety cutout
Action: Auto-reset, normally-closed
Mounting: Factory-matched trip temperature and bracket
Fits: ADSH801005CXAB and compatible Goodman/Amana furnaces
Type: Direct OEM replacement

OEM vs. Generic

This genuine OEM Goodman part (20162901) is calibrated to the exact trip temperature your furnace was designed around. Generic limit switches often have different set points or bracket geometry, which can cause nuisance trips or — worse — fail to open when needed. For a safety-critical control, OEM is the right choice.

Installation Difficulty

Easy to Moderate — Typically two mounting screws and two spade terminals. Shut off power first, note wire positions, and confirm the bracket seats flush against the mounting surface. Most handy homeowners can complete this in 15–20 minutes; when in doubt, consult an HVAC technician.

Always disconnect electrical power before servicing your furnace.
