The Goodman B1370188 is a genuine OEM 170°F primary high-limit switch for the GMV80704BXA furnace and compatible Goodman/Amana models. Mounted on the heat exchanger or blower deck, this auto-reset control opens the circuit to the gas valve if supply-air temperature exceeds a safe threshold — protecting the furnace from overheating due to restricted airflow, a dirty filter, or a failing blower. Short-cycling on heat is a classic sign of a marginal or failed primary limit.

Specifications

Trip temperature: 170°F (open on rise)
Type: Auto-reset primary high-limit switch
Function: Supply-air overheat protection
Fits: Goodman GMV80704BXA furnace
OEM Part Number: B1370188

OEM vs. Generic

The OEM B1370188 matches Goodman's exact 170°F setpoint, disc size, and bracket geometry. Because this control governs furnace safety and cycling, an incorrectly rated generic can cause nuisance shutdowns or allow unsafe temperatures. OEM is strongly recommended.

Installation Difficulty

Easy — Two mounting screws and two spade terminals. Plan 15 minutes. Cut power before servicing and verify airflow (filter, blower, ducting) is not the underlying cause.
