Description
The Goodman B1370113 is an OEM auto-reset limit switch engineered to protect Goodman heating systems from unsafe operating temperatures. Designed as a direct factory replacement, this limit switch monitors heat exchanger and plenum temperatures, automatically resetting once safe conditions are restored — minimizing downtime and service calls.
Product Overview
Limit switches are a critical safety component in gas furnaces and air handlers. When temperatures exceed the rated threshold, the limit switch interrupts the burner circuit to prevent overheating, heat exchanger damage, and potential fire hazards. The auto-reset function means the switch will restore normal operation once temperatures return to a safe level, without requiring manual intervention.
