The Goodman 20162906 M4 Primary Limit Switch is a genuine OEM high-limit control for the Goodman/Amana ACES961205DNAA gas furnace. Mounted on the heat-exchanger bulkhead, this primary limit senses supply-air temperature and opens the gas-valve circuit if the furnace overheats — typically due to restricted airflow, a dirty filter, or a failed blower. It protects the heat exchanger from thermal stress and prevents dangerous over-temperature operation.

Specifications

Type: M4-series primary high-limit switch
Reset: Automatic (re-closes when temperature normalizes)
Function: Supply-air over-temperature protection
Brand: Goodman / Amana OEM
Direct fit: ACES961205DNAA heat-exchanger bracket

OEM vs. Generic

The OEM M4 limit (20162906) is factory-calibrated to the trip temperature and bracket geometry for this specific furnace. Generic limits with different cut-out points or stem lengths can cause nuisance shutdowns or fail to protect the heat exchanger. For correct fit and protection, use the OEM part.

Installation Difficulty

Easy (1/5). Disconnect two spade terminals, remove the mounting screws, and swap in the new switch. Always cut power before servicing. If the furnace was tripping on limit, correct the underlying airflow restriction (filter, ductwork, blower) before returning to service.
