Heil Quaker ICP 1053017 Pressure Switch

When high-head pressure threatens to compromise your compressor, the Heil Quaker ICP 1053017 Pressure Switch provides the essential fail-safe your system requires. Engineered for heavy-duty HVACR applications, this 450# M/R high pressure switch is designed to monitor refrigerant levels and open the electrical circuit if pressures exceed safe operating limits. As a manual reset (M/R) pressure switch, it prevents the system from automatically restarting, forcing a technician to inspect for underlying issues like a clogged condenser coil, failing fan motor, or refrigerant overcharge before resuming operation. This ICP high pressure cutout is a direct replacement for many Heil, Quaker, and Tempstar units, ensuring seamless HVAC pressure switch compatibility and protecting the "heart" of the system from catastrophic failure during high-ambient conditions.

• Critical System Protection: Acts as an HVAC safety switch, preventing $1000+ compressor replacements due to extreme internal pressures.
• Manual Reset Feature: Ensures a professional diagnostic is performed, preventing "ghost" cycling that damages contactors.
• Precise 450 PSI Setpoint: Specifically calibrated for high-pressure R-410A or R-22 systems requiring a 450# cutout.
• Rugged Build Quality: High-grade internal leads and housing designed for the vibration and thermal cycling of outdoor condensing units.

• What causes this switch to trip? Typically, restricted airflow over the outdoor coil, an overcharged system, or a non-functioning condenser fan motor will drive head pressure past the 450 PSI limit.
• How do I check if the switch is open? Use a multimeter to check for continuity across the terminals. If the system is off and the switch is open (no continuity), it has tripped and requires a manual reset and investigation.
• Is this compatible with my specific Heil unit? This part is a standard OEM replacement for ICP-branded equipment. Always verify the pressure rating on the existing switch's label to ensure a proper match for the system's design.
