Amana-Goodman B1370194 Limit Switch

The Amana-Goodman B1370194 Limit Switch is a critical safety component designed for high-temperature monitoring within HVAC air handlers and furnaces. This OEM replacement limit switch features an automatic reset mechanism calibrated for a 220-250F temperature range, ensuring the system shuts down if internal temperatures exceed safe operating parameters. Engineered to meet precise Goodman furnace parts specifications, this switch prevents heat exchanger damage and potential fire hazards caused by restricted airflow or blower failure. Contractors can rely on this L250-30F limit control for its high-cycle reliability and exact fit, eliminating the need for field modifications. When diagnosing short-cycling or thermal cutout issues, verifying the integrity of the high limit safety switch is essential. This genuine Amana replacement part ensures the system maintains UL compliance and operational safety standards during high-demand heating cycles.

• Precise Thermal Calibration: Precisely opens at 250°F to prevent thermal runaway and closes at 220°F for automated recovery.
• OEM Compatibility: Designed specifically for Amana and Goodman platforms to ensure proper terminal alignment and mounting depth.
• Durable Construction: Built to withstand the harsh environment of a heat exchanger cabinet without drift in setpoint accuracy.
• Safety Compliance: Functions as a primary safety limit to protect the furnace from overheating due to static pressure issues.

Common Questions

What causes a furnace limit switch to trip frequently?
Repeated tripping is usually indicative of restricted airflow, often caused by a dirty air filter, blocked return air ducts, or a failing blower motor increasing the internal cabinet temperature.

Is the B1370194 an automatic or manual reset switch?
This is an auto-reset limit switch, meaning it will automatically close the circuit once the temperature drops below the 220°F threshold.

Can I use a universal limit switch instead of the B1370194?
While universal parts exist, using this genuine Goodman B1370194 is recommended to ensure the temperature setpoints and physical probe length match the original factory safety requirements.
