Amana-Goodman B1370116 Limit Switch

The Amana-Goodman B1370116 Limit Switch is a critical safety component designed for specific furnace and air handler applications. This OEM Goodman replacement part features a fixed temperature setting, functioning as an auto-reset limit switch that opens at 140°F and closes at 115°F. Engineered to monitor heat exchanger temperatures, this high limit safety switch prevents thermal over-stress by interrupting the burner circuit if airflow is restricted or the blower motor fails. As a genuine HVAC furnace limit control, it ensures precise calibration for compatible Goodman, Amana, and Janitrol systems. For contractors performing diagnostic repairs, this switch is the direct B1370116 furnace part solution for resolving code trips related to overheating. Proper installation requires verifying that the thermal range matches the original equipment manufacturer specifications to maintain localized safety logic and system integrity during high-static conditions.

• Direct OEM Compatibility: Ensures seamless fit and function in Amana and Goodman primary heat exchanger assemblies.
• Automatic Reset Logic: Automatically closes the circuit at 115°F, restoring system operation once the plenum cools.
• Precise Thermal Calibration: Factory-set 115-140F range provides accurate over-temperature protection without drift.
• Industrial Build Quality: Constructed to withstand high-cycle thermal environments common in residential gas furnaces.

What causes this limit switch to trip repeatedly?
Repeated tripping usually indicates restricted airflow, such as a clogged furnace filter, blocked return air ducts, or a failing blower motor capacitor.

Is this switch compatible with Janitrol units?
Yes, as Goodman manufactured Janitrol equipment, this part is often the specified replacement for Janitrol furnaces requiring a 140-degree limit.

Can I bypass this switch for testing purposes?
While technicians may briefly jump the switch to diagnose a terminal failure, the system must never be left operating without a functional limit switch due to fire hazards.
