Amana-Goodman 10123525 Limit Switch

The Amana-Goodman 10123525 Limit Switch is a critical safety component designed for high-limit temperature monitoring in residential gas furnaces and air handlers. Engineered as an OEM manual reset limit switch, this part is calibrated to a fixed 160F trip point, ensuring that the burner circuit is interrupted if internal plenum temperatures exceed safe operating parameters. Unlike auto-reset controls, this 160-degree manual reset switch requires a technician to physically investigate the cause of the high-limit trip—such as a failed blower motor, dirty filter, or restricted ductwork—preventing repeated cycling under unsafe conditions. This genuine Goodman replacement part features a standard small footprint for easy mounting within the heat exchanger vestibule. Integrating this factory-tested switch ensures signal continuity within the 24V safety string, maintaining the precise sequence of operation required for Amana and Goodman HVAC systems and protecting the heat exchanger from thermal stress.

• OEM Precision: Guaranteed compatibility with specific Amana and Goodman furnace models for reliable safety circuit integration.
• Fixed Thermal Calibration: Factory-set at 160F (71C) to provide an accurate thermal cutoff for the combustion system.
• Manual Reset Mechanism: Enhances system safety by locking out the furnace until a technician identifies the source of overheating.
• Durable Construction: Built to withstand high-temperature environments near the heat exchanger without premature fatigue.

How do I know if my 10123525 limit switch is tripped?
If the furnace blower runs continuously while the burners fail to ignite, check for continuity across the switch terminals. A tripped manual reset switch will show an open circuit until the center button is depressed.

Can I bypass the 160F limit switch for testing?
Bypassing a safety limit is not recommended. If the furnace limit switch keeps tripping, verify static pressure and airflow across the evaporator coil before replacing the component.

Is the 10123525 compatible with other brands?
While functionally similar to other HVAC limit switches, this part is specifically engineered for Goodman, Amana, and Janitrol equipment. Always verify the part number against the unit’s wiring diagram.
