The Goodman 20162901 Primary Limit Switch is a genuine OEM temperature-sensing safety control built for the Goodman ADSH801005CXAA gas furnace. Mounted on the heat exchanger bulkhead, the primary limit continuously monitors supply-air temperature. If airflow is lost or the furnace overheats, the switch opens to shut off the gas valve and burners, then automatically resets once temperatures return to a safe range. It is the furnace's first line of thermal protection.

OEM Part Number: 20162901
Brand: Goodman (genuine OEM)

OEM vs. Generic

The genuine 20162901 arrives pre-calibrated to the factory-specified open/close temperatures with the correct disc diameter and bracket. Substituting a generic snap-disc with the wrong trip point can cause short cycling on limit or, worse, fail to protect the heat exchanger. OEM ensures matched protection and a clean fit.

Install Difficulty

Easy (2/5). Disconnect power, unplug the two wire terminals, remove the mounting screws, and swap in the new limit. Roughly 15 minutes. Confirm the sensing element seats in the airstream exactly as the original did.
