Price Industries 019769-001 Limit Switch
For veteran HVAC contractors, the Price Industries 019769-001 Manual Reset Limit Switch is a critical safety component designed for terminal units, fan-powered induction boxes, and high-temperature air handling systems. Calibrated for a precise 150°F trip point, this thermal safety control prevents equipment damage and catastrophic failure by interrupting the electrical circuit upon detecting excessive heat levels. As a Manual Reset (M/R) control, it ensures the system remains offline after a high-limit event, forcing a technician to inspect the heat exchanger, blower motor, or airflow paths before manually clearing the trip. Constructed with a compact furnace limit switch housing, the 019769-001 integrates seamlessly into tight control compartments within Price Industries electric reheat coils and HVAC terminal units. This OEM replacement part is essential for maintaining code compliance and protecting downstream ductwork in commercial high-demand environments. Its reliable thermal protection and rugged design ensure consistent performance across diverse HVAC safety control applications.
Key Benefits:
- Enhanced Safety Logic: The 150-degree manual reset mechanism prevents dangerous "auto-cycling" of a failing system, requiring a physical HVAC technician inspection before restarting.
- OEM Compatibility: Specifically engineered for Price Industries terminal units and electric coils, ensuring exact factory flight and electrical clearance.
- Industrial Durability: Robust internal contacts and high-precision engineering provide long-term reliability in commercial heating applications.
- Compact Mounting: The low-profile design allows for easy installation in dense electrical control panels and air handler housings.
- Critical System Safeguard: Protects high-value components and ductwork from overheating failures caused by airflow obstructions or motor stalls.
Common Questions:
What causes this limit switch to trip repeatedly?
Repeated trips usually indicate airflow restriction due to clogged HVAC filters, a failing blower motor, or restricted ductwork. If the 150F limit switch trips, verify static pressure and heat exchanger integrity before resetting.
Can I replace a manual reset switch with an automatic reset model?
No. A manual reset limit switch is often a mandated safety feature for specific heating equipment. Swapping to an automatic reset version can create a fire hazard by allowing the unit to cycle indefinitely under fault conditions.
How do I test if the 019769-001 is faulty?
Using a multimeter, check for continuity across the terminals when the switch is cool. If the circuit remains open after a reset attempt at room temperature, the high-limit safety control must be replaced.
