Goodman 20162906 M4 Primary Limit Switch

The Goodman/Amana 20162906 M4 primary limit switch is a critical safety control that monitors heat-exchanger temperature in your furnace. If the plenum overheats — often from restricted airflow or a failed blower — the limit switch opens and shuts off the burners to prevent damage and hazardous conditions. This genuine OEM switch is calibrated for the AMEC960603BNBA and matching Goodman/Amana furnaces so it trips at the correct temperature and resets reliably.

Specifications

OEM Part Number: 20162906
Type: M4 Primary High-Limit Switch (auto-reset)
Function: Over-temperature safety cutout
Equipment: Gas Furnace
Compatible Model: AMEC960603BNBA (and select Goodman/Amana furnaces)
Factory-calibrated trip temperature

OEM vs. Generic

The OEM 20162906 is set to the exact cut-out and cut-in temperatures Goodman specifies for this heat exchanger. Generic limit switches may trip at the wrong temperature, causing nuisance lockouts or, worse, failing to protect the furnace. As a safety device, the genuine OEM part is the recommended choice.

Installation Difficulty

Rating: Easy to Moderate. The switch mounts to the burner or heat-exchanger bulkhead with two screws and two spade terminals. Turn off power and gas first, note wire positions, and match the mounting orientation. Most DIYers with basic tools can complete this in 15–30 minutes; when in doubt, use a licensed technician.
