Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 Primary Limit Switch is a genuine OEM 150°F high-limit safety control for the AMVM971005CNBA modulating variable-speed furnace and other compatible Goodman and Amana models. Mounted on the heat exchanger or blower deck, this thermal switch senses supply-air temperature and opens the control circuit if the furnace overheats — typically from restricted airflow, a dirty filter, or a failed blower. It protects the heat exchanger from cracking and prevents unsafe operating temperatures.

Specifications

  • OEM Part Number: 20162903
  • Part Type: Primary / High-Limit Switch
  • Trip Point: 150°F (opens on temperature rise)
  • Configuration: Normally closed, automatic reset
  • Fits: Goodman / Amana AMVM971005CNBA and compatible furnace models
  • Category: Safety Limit Switch

OEM vs. Generic

The OEM 20162903 is factory-calibrated to the precise 150°F set point and mounting pattern. Generic replacements with different trip temperatures can cause short-cycling on limit or, dangerously, allow the furnace to overheat. For a heat-exchanger safety control, insist on genuine OEM.

Installation Difficulty

Moderate (2/5). Turn off gas and power, unplug the spade terminals, remove the mounting screws, and install the new switch in the same orientation and location. Address the underlying airflow issue that caused the trip before returning the furnace to service.
