Description
The Amana‑Goodman B1370920 is a genuine OEM 7‑inch primary limit switch used in many Goodman, Amana, and Janitrol furnaces. This switch helps manage internal furnace temperatures by opening the safety circuit when it reaches its trip threshold (around 180 °F).
Features:
- Genuine OEM Part: This is a factory‑original limit switch, not a generic aftermarket substitute—guaranteeing compatibility and trustworthy performance.
- 180 °F Trip Rating (L180‑30): The B1370920 opens the circuit at approximately 180 °F to protect the furnace from overheating.
- 7‑Inch Length: With a 7″ insertion depth, it reaches properly into the heat exchanger chamber for accurate temperature sensing.
- Automatic Reset / Auto Limit (150‑180 °F Range): In many configurations, this switch is marketed as “150‑180 °F auto limit,” meaning it allows automatic cycling under normal operating temperatures.
- Robust Construction: Built to withstand repeated thermal cycling, ensuring reliable operation and a longer service life.
- Direct Replacement & Easy Installation: Designed for plug‑in replacement in compatible furnace models, facilitating quick servicing and minimal downtime.
