Goodman 20162906 M4 Primary Limit Switch

The genuine Goodman 20162906 M4 primary limit switch is a factory OEM high-temperature safety control for the AMVC960603BNBA modulating variable-speed gas furnace and compatible Goodman/Amana models. Mounted on the heat-exchanger bulkhead, this auto-reset thermal switch monitors supply-air temperature and opens the control circuit to shut down heating if airflow is lost or the furnace overheats — protecting the heat exchanger from cracking and the cabinet from heat damage. It automatically resets once temperatures return to a safe range.

OEM Part Number: 20162906
Part Type: M4 Primary High-Limit Switch
Contact Configuration: Normally Closed, auto-reset
Function: Supply-air overtemperature protection
Compatible Model: AMVC960603BNBA
Brand: Goodman / Amana

OEM vs. Generic

The OEM Goodman M4 limit is calibrated to the exact trip point and mounting footprint for this furnace. Generic substitutes with different setpoints or bracket dimensions can cause nuisance lockouts or inadequate protection. As a primary safety control, OEM calibration matters.

Installation Difficulty

Moderate (2/5) — remove the mounting screws, transfer the wire connectors, and seat the new switch flush against the heat exchanger. Cut gas and power before servicing; repeated tripping usually signals a blower/airflow or filter problem that must be corrected.
