Amana-Goodman 10123534SP Limit Switch

The Amana-Goodman 10123534SP Limit Switch is a critical safety component designed for precise thermal monitoring within high-efficiency furnace systems. This L220F manual reset rollout switch is engineered to detect Flame Rollout conditions, specifically when heat exchanger combustion gases bypass the primary venting. Operating as a normally closed contact, it opens the circuit at a fixed 220-degree Fahrenheit trip point, immediately halting the gas valve to prevent cabinet overheating and potential fire hazards. As the 10123534SP direct replacement for 10123534, this OEM component ensures exact fitment and electrical continuity for Goodman, Amana, and Janitrol units. For technicians performing furnace limit switch replacement, this part provides the specific thermal response curve required to maintain UL safety listings and equipment integrity. The manual reset functionality requires a physical inspection of the burner assembly, a vital step in HVAC troubleshooting to identify underlying drafting or manifold pressure issues before system reactivation.

• OEM Compatibility: Direct factory replacement ensures proper mounting alignment and terminal orientation for Goodman furnace parts.
• Fixed Thermal Calibration: Calibrated to trip at exactly 220°F (L220F) to protect the heat exchanger and surrounding components.
• Manual Reset Safety: Prevents automatic cycling of a failing system, forcing a professional HVAC flame rollout scan.
• High-Grade Construction: Built to withstand the high-ambient temperatures found near the burner box and vestibule panel.

Can I bypass this switch for testing purposes?
No. This limit switch is a primary safety device. Bypassing it, even temporarily, risks cracked heat exchangers and fire. Always diagnose the cause of the trip, such as a blocked flue or failed inducer motor.

Why does my flame rollout switch keep tripping?
Frequent tripping usually indicates poor combustion air, restricted secondary heat exchangers, or positive pressure in the combustion chamber. Check the Amana-Goodman 10123534SP for soot or physical damage during your inspection.

Is the 10123534SP compatible with older 10123534 models?
Yes, the 10123534SP is the updated service part number and is fully compatible with all applications previously utilizing the 10123534 switch.
