Amana-Goodman 10123536 Limit Switch

The Amana-Goodman 10123536 Limit Switch is a critical safety component designed for high-limit temperature monitoring in residential gas furnaces and air handlers. This specific 180F manual reset limit switch is engineered to interrupt the electrical circuit if the heat exchanger exceeds the specified 180-degree Fahrenheit threshold, preventing equipment damage and ensuring safe operation. As a genuine OEM replacement part, it maintains the precise calibration required for Goodman, Amana, and Janitrol HVAC systems. The M/R limit switch configuration requires a manual intervention to reset the system after a thermal trip, alerting the service technician to potential airflow restrictions, failed blower motors, or blocked secondary heat exchangers. Built with durable bimetal sensing technology and standard 1/4 inch spade terminals, the 10123536 furnace safety switch provides reliable performance and direct compatibility with existing mounting brackets for efficient field replacement in HVAC furnace repair applications.

• OEM Precision: Direct replacement ensures correct temperature calibration and terminal orientation for original equipment manufacturers.
• Manual Reset Safety: Forced manual reset prevents the system from cycling under unsafe thermal conditions, protecting the heat exchanger.
• High-Temperature Rating: Specifically calibrated to 180°F for high-capacity heating applications.
• Rapid Response: Bimetal disc provides high-sensitivity thermal detection for immediate circuit interruption.

Is the 10123536 limit switch compatible with my furnace model?
This part is widely used in Goodman and Amana gas furnaces. You should verify the temperature rating and part number against your unit's parts manual or existing switch markings.

What causes this 180F M/R limit switch to trip?
Common causes include a dirty air filter, failing blower motor, restricted ductwork, or a cracked heat exchanger causing excessive internal temperatures.

Can I replace a manual reset switch with an automatic reset switch?
No. System safety protocols require the manual reset feature to ensure a technician inspects the cause of the overheating event before the furnace resumes operation.
