The Goodman 20162906 M4 Primary Limit Switch is a genuine OEM high-limit safety control for the Goodman ACEC960603BNAA gas furnace. Mounted on the heat-exchanger / blower deck, this auto-reset thermal switch monitors supply-air temperature and opens to interrupt the gas valve if the furnace overheats — typically from restricted airflow, a dirty filter, or a failing blower. It closes again once temperatures return to normal, allowing the furnace to resume. A failed primary limit causes short cycling, no heat, or burners that fire then drop out.

Specifications

OEM Part Number: 20162906
Part Type: M4 Primary High-Limit Switch
Function: Auto-reset; opens on over-temperature
Brand: Goodman (also fits select Amana builds)
Fits Model: ACEC960603BNAA
Fit: Direct OEM replacement — factory setpoint and mounting

OEM vs. Generic

The primary limit is calibrated to a specific open/close temperature tied to the furnace's airflow and heat-exchanger design. A generic limit with the wrong trip point can nuisance-trip or fail to protect the heat exchanger. The genuine Goodman 20162906 carries the correct factory setpoint and bracket for the ACEC960603BNAA, restoring proper safety operation. For a safety control, OEM is strongly recommended.

Installation Difficulty

Moderate (3/5). Remove two mounting screws, transfer the spade connectors, and seat the new switch against the deck. Shut off power and gas before servicing. If the limit keeps tripping after replacement, diagnose the airflow restriction rather than bypassing the switch.

Genuine OEM safety part. Verify your full model and serial number before ordering.
