Heil Quaker ICP 1013862 Pressure Switch

The Heil Quaker ICP 1013862 Pressure Switch is a critical OEM safety component designed for 80% AFUE two-stage gas furnaces. This dual vent pressure switch assembly is calibrated with specific set points of 0.30" WC and 0.59" WC to monitor the static pressure produced by the inducer motor. As a veteran technician knows, maintaining the correct vacuum is vital for ensuring the furnace flues safely and the burner sequence initiates correctly. This ICP 1013862 replacement is engineered for high-performance industrial and residential applications, providing accurate switching for air and gas pressures. It features a rugged, compact construction that fits seamlessly into tight vestibules. When diagnosing "pressure switch stuck open" codes, this genuine HVAC furnace pressure switch provides the precision response time required to resolve intermittent cycling or ignition failures. Compatible with a wide range of brands including Tempstar, Comfortmaker, Arcoaire, and KeepRite, this part is the reliable choice for maintaining system integrity and operational efficiency in 2-stage vent systems.

• Precise Dual Calibration: Factory-set at 0.30" and 0.59" WC for accurate 2-stage performance monitoring.
• Broad OEM Compatibility: Directly replaces Honeywell BA20120 and fits numerous ICP, Heil, and Day & Night models.
• Durable Construction: Built to withstand the harsh thermal environments of a furnace cabinet.
• Standardized Connections: Features two wiring terminals and a single hose port for straightforward field installation.
• Safety Optimized: Ensures the inducer motor is moving sufficient air to safely vent combustion gases before ignition.

Is the ICP 1013862 adjustable in the field?
No, this switch is factory-preset to specific water column inches to meet original equipment safety standards. Attempting to adjust the set points can lead to unsafe furnace operation.

What does a dual pressure switch do in a two-stage furnace?
It monitors different pressure thresholds for low-fire and high-fire stages, ensuring the inducer is pulling enough draft at both motor speeds.

What causes this switch to fail frequently?
While the switch itself is robust, failure is often caused by moisture in the sensing lines, a cracked heat exchanger, or a restricted chimney flue rather than a mechanical defect in the switch.
