The Goodman 20162901 Primary Limit Switch is a genuine OEM high-limit safety control built for the ACVM970804CNAA gas furnace and compatible Goodman/Amana units. Mounted on the heat exchanger or burner deck, this primary limit continuously monitors plenum temperature and de-energizes the gas valve if the furnace overheats — typically from restricted airflow such as a dirty filter or failed blower.

Specifications

Part Number: 20162901
Type: Primary high-limit switch
Function: Auto-reset overheat cutout
Mounting: Heat-exchanger / burner-box bracket mount
Brand: Goodman (OEM)
Fits Model: ACVM970804CNAA furnace

OEM vs. Generic

The genuine Goodman OEM primary limit is set to the precise temperature and insertion depth required for safe operation of your specific furnace. Generic replacements may not match the probe length or trip point, which can cause nuisance trips or, worse, fail to protect the heat exchanger. For a safety-critical part like this, OEM is the right choice.

Installation Difficulty

Moderate (3/5) — Requires hand tools and care. Shut off power and gas, document the wiring, remove the mounting screws, and replace the switch with the sensing element inserted to the same depth and orientation. Persistent tripping indicates an airflow or blower problem that should be corrected.
