Goodman B1370189 Primary Limit Switch (200F)

The B1370189 is a genuine OEM primary high-limit switch engineered for the Goodman/Amana ADV80905CXA gas furnace and compatible models. This normally-closed thermal safety control mounts to the heat exchanger bulkhead and continuously monitors supply-air temperature. If airflow is lost or the furnace overheats, the switch opens at its 200°F trip point to shut down the burners, protecting the heat exchanger and your home from unsafe operation.

Specifications

Part number: B1370189
Type: Primary high-limit / temperature safety switch
Trip point: 200°F (opens on rise)
Action: Normally closed, auto-reset
Terminals: 1/4 in. male quick-connect spades
Fits: Goodman / Amana ADV80905CXA and related 80% AFUE furnaces

OEM vs. Generic

This is a factory-original Goodman part calibrated to the exact 200°F set point specified for the ADV80905CXA. Generic universal limit switches often carry a different trip temperature or mounting footprint, which can cause nuisance lockouts or, worse, allow overheating. For a safety control, the OEM match is the reliable choice.

Installation Difficulty: Easy

Replacement is a two-screw job for most homeowners: shut off power and gas, remove the burner-compartment door, disconnect the two spade terminals, unthread the two mounting screws, and swap in the new switch. Reconnect and restore power. Typical time is 15–20 minutes. When in doubt, have a licensed HVAC technician confirm the fault before replacing.
