Amana-Goodman B1370145 Rollout Switch

The Amana-Goodman B1370145 Rollout Switch is a critical safety component designed for specific furnace and air handler applications. This single-pole single-throw (SPST) flame rollout switch triggers at 300 degrees Fahrenheit, acting as a high-limit thermal cutoff to prevent unsafe combustion conditions. Featuring a manual reset mechanism, this part requires a technician to inspect the heat exchanger and venting system for blockages or cracks before restoring operation. Engineered for compatibility with Goodman, Amana, and Janitrol gas furnaces, the B1370145 HVAC safety switch ensures precise thermal monitoring in high-temperature environments. When diagnosing furnace rollout switch tripping, this OEM replacement provides the exact electrical specifications and mounting orientation required for Goodman furnace repair. Ensure your HVAC flame sensor and draft inducer are functioning correctly when installing this thermal limit switch to maintain system integrity and prevent repeated open-circuit conditions.

• Precision Calibration: Opens at a fixed 300°F threshold to provide reliable protection against flame rollout.
• OEM Compatibility: Direct replacement for various Amana and Goodman models, ensuring proper fitment and terminal alignment.
• Manual Reset Safety: Forces professional inspection of the combustion area before the system can be restarted.
• Durable SPST Construction: Built to withstand the harsh thermal cycles of a furnace burner transition box.

Common Questions

What causes a 300-degree rollout switch to trip?
Tripping is typically caused by a restricted flue, a cracked heat exchanger, or insufficient combustion air causing flames to "roll out" of the burner area.

Can I bypass this switch for testing?
Temporary bypassing is only for immediate diagnostic use by a qualified technician; the unit must never be operated without a functional rollout switch.

Is the B1370145 compatible with all Amana furnaces?
No, compatibility depends on the specific BTU rating and cabinet design. Always verify the temperature rating on the existing switch before replacement.
