Goodman 20162906 M4 Primary Limit Switch

The Goodman 20162906 M4 Primary Limit Switch is a genuine OEM high-limit safety control mounted on the heat-exchanger/blower section of the furnace. It continuously monitors supply-air temperature and opens the circuit to shut down the burners if airflow is restricted and temperatures climb too high — protecting the heat exchanger from damage. This M4-series primary limit is a direct-fit replacement for the Goodman ACVC960403BNBA furnace.

Specifications

OEM Part Number: 20162906
Brand: Goodman (OEM)
Equipment: Gas Furnace

OEM vs. Generic

The OEM Goodman M4 limit is factory-calibrated to the precise trip and reset temperatures for this model. Substituting a switch with a different setpoint risks nuisance lockouts or inadequate over-temperature protection. For a primary safety device, OEM is the right choice.

Installation Difficulty

Moderate (2/5). Involves removing the blower-compartment panel, unplugging the wiring connector, and unscrewing the limit from its mounting. Shut off power and gas before servicing, and correct any airflow restriction (dirty filter, closed registers, failing blower) that may have caused a trip.
