Goodman 20162903 Primary Limit Switch (150°F)

This genuine OEM Goodman 20162903 primary limit switch is the 150°F high-limit safety control for the Goodman/Amana AMS950704CXAB gas furnace and compatible models. Mounted on the heat-exchanger bulkhead, it monitors supply-air temperature and de-energizes the burners if the furnace overheats — typically from restricted airflow such as a dirty filter, blocked return, or failed blower. Its auto-reset action closes again once temperature returns to a safe range.

Type: Primary high-limit switch, auto reset
Trip point: 150°F (opens on rise)
Application: Heat-exchanger / supply-air over-temperature protection
Fits: Goodman & Amana AMS950704CXAB and related furnaces
Contacts: Normally closed, opens above setpoint

OEM vs. Generic

The OEM 20162903 is factory-calibrated to the correct 150°F setpoint and matches the original mounting flange and insertion depth. Generic limit switches often differ in trip temperature or probe length, causing short-cycling or unsafe operation. For a primary safety limit, OEM calibration matters.

Install Difficulty

Easy (1/5). Turn off power and gas, remove two mounting screws and two spade terminals, and install the replacement in the same orientation. About 15 minutes. If the furnace keeps hitting the limit, check the filter and blower before assuming the switch is faulty.
