Goodman 20162903 Primary Limit Switch (150°F)

The 20162903 is a genuine Goodman OEM primary high-limit switch rated at 150°F for the AMVM971005CNAA modulating variable-speed gas furnace. Mounted on the heat-exchanger bulkhead, this auto-reset thermal switch continuously monitors supply-air temperature and opens the control circuit if the plenum overheats — typically from restricted airflow such as a dirty filter, failed blower, or closed ducts. When temperatures return to normal, the switch automatically closes and restores heating.

Specifications

Part type: Primary high-limit switch (auto-reset)
Trip temperature: 150°F open point
OEM part number: 20162903
Compatible model: AMVM971005CNAA (AMVM97 series)
Equipment: 100,000 BTU modulating condensing furnace
Contacts: Normally closed, opens on overtemperature

OEM vs. Generic

Primary limit switches are matched to the furnace by both trip temperature and bracket geometry. The genuine Goodman 20162903 carries the exact 150°F setpoint and mounting profile the AMVM97 requires. An incorrectly-rated aftermarket switch causes short-cycling or lets the heat exchanger run too hot — always match the OEM spec on a safety control.

Installation Difficulty

Moderate (2/5). Cut power and gas, photograph the wiring, remove the two mounting screws, transfer the terminals, and reinstall in the same orientation. Standard hand tools. If the switch was tripping, diagnose and clear the airflow restriction first.
