Amana-Goodman 10123533SP Limit Switch

The Amana-Goodman 10123533SP Limit Switch is a critical safety component designed for high-temperature monitoring in residential furnaces and air handlers. This specific 200F CO M/R limit switch features a 200-degree Fahrenheit cutout point with a manual reset (M/R) configuration, ensuring the system remains offline if an over-temperature condition occurs until a technician can verify heat exchanger integrity. As a direct replacement for OEM part 10123533, it maintains factory specifications for circuit interruption and mounting orientation. For contractors troubleshooting cycling issues or rollout failures, this high-limit safety switch provides essential protection against overheating caused by restricted airflow or cracked heat exchangers. Proper installation of this furnace limit control is necessary to maintain the sequence of operation and ensure the inducer and blower fans function within safe thermal parameters. This Goodman replacement part is engineered for precision tolerances, minimizing nuisance trips while providing reliable thermal protection in demanding HVACR applications.

• Precise Thermal Calibration: Calibrated at a 200-degree cutout to prevent damage to the heat exchanger and surrounding components.
• Manual Reset Safety: The manual reset (M/R) feature forces a manual inspection of the system, preventing the unit from automatically restarting under unsafe conditions.
• Direct OEM Swap: Fully compatible with systems requiring part number 10123533, ensuring no modifications are needed for mounting or wiring.
• Durable Construction: Built to withstand the high-cycle environment of a gas furnace plenum, ensuring long-term reliability in the field.

What causes a 200F limit switch to trip?
Tripping is typically caused by restricted airflow, such as a dirty air filter, blocked return air, or a failing blower motor, leading to excessive internal temperatures.

Is the 10123533SP different from the 10123533?
No, the 10123533SP is an identical service part to the 10123533, utilizing the same technical specifications and 200F thermal rating.

Can I bypass this switch for testing?
While technicians may briefly jump a switch for diagnostic verification, this safety device must never be bypassed during normal operation as it protects against fire hazards.
