Amana-Goodman 20162904 Limit Switch

The Amana-Goodman 20162904 Limit Switch is a critical safety component designed for specific furnace and air handler applications. This rollout limit switch is calibrated for a 150-degree Fahrenheit cut-out, utilizing an automatic reset mechanism to protect the secondary heat exchanger and internal components from overheating. As a genuine OEM HVAC replacement part, the 20162904 ensures precise thermal response and electrical continuity within the furnace control circuit. It is engineered to monitor high-temperature conditions and interrupt power to the gas valve if temperatures exceed the 150F threshold. Common in Goodman gas furnaces and Amana heating systems, this switch features a standard disc-style thermal sensor and spade terminals for a secure, low-resistance connection. Proper installation requires verifying the temperature rating against the original equipment manufacturer's specifications to ensure the combustion blower and heat exchanger operate within safe parameters.

• Automatic Reset: Returns to a closed state once the temperatures drop below the 150F threshold, minimizing system downtime.
• Precise 150F Cut-Out: Calibrated specifically for high-limit protection to prevent heat exchanger damage or unsafe operating conditions.
• OEM Compatibility: Designed for a drop-in fit for numerous Amana and Goodman furnace models, ensuring reliable terminal alignment and mounting.
• Durable Construction: Built to withstand the high-cycle demands of modern high-efficiency HVAC equipment.

Can I use a higher temperature limit switch if this one keeps tripping?
No. The 150F rating is specified to protect your exact model's internal components. If the switch trips frequently, it indicates an underlying airflow issue or combustion problem that must be diagnosed by a technician.

Is the 20162904 compatible with my furnace model?
This 150F CO auto limit switch fits many Goodman/Amana units, but you should always verify the part number against your unit's specific parts list or wiring diagram.

What causes a rollout switch to fail?
Beyond thermal fatigue, failures are often caused by restricted airflow, dirty filters, or a cracked heat exchanger causing abnormal heat distribution.
