The Goodman 20162901 Primary Limit Switch is a genuine OEM high-temperature safety control for the ADSS801005CXAA gas furnace and related Goodman/Amana models. Mounted on the heat-exchanger vestibule, this normally-closed thermal switch opens if plenum temperature climbs past its trip point—shutting off the gas valve to prevent a cracked heat exchanger or fire. A failed limit switch is a common cause of a furnace that short-cycles, locks out, or refuses to heat.

Specifications

Type: Primary high-limit safety switch (auto-reset, normally closed)
Function: Opens gas valve circuit on plenum overheat
Fitment: Goodman/Amana furnaces incl. ADSS801005CXAA
Trip temperature: Factory-calibrated to furnace spec
OEM Part Number: 20162901

OEM vs. Generic

The OEM 20162901 is calibrated to the exact trip temperature and mounting footprint your furnace was designed around. Because this is a life-safety device, a generic switch with the wrong setpoint or bracket can allow overheating or cause nuisance shutdowns. We strongly recommend OEM for all safety controls.

Installation Difficulty

Easy — Cut power at the disconnect, unplug the two spade terminals, remove two screws, and install the replacement. Most homeowners complete this in 15–20 minutes with a nut driver. Restore power and verify a full heat cycle.

Ships quickly and covered by our ADSS801005CXAA fitment guarantee.
