Heil Quaker ICP 1173649 Reversing Valve

The Heil Quaker ICP 1173649 Reversing Valve is a critical 4-way flow control component designed for International Comfort Products (ICP) heat pump systems. Built for heavy-duty refrigerant management, this OEM replacement reversing valve utilizes a slide-type mechanism to shift the direction of the refrigerant, allowing the system to toggle between heating and cooling cycles. This specific model includes a 24V solenoid coil, which provides the electromagnetic force necessary to actuate the pilot valve. Operating on standard low-voltage control circuits, it ensures a seamless transition by creating the required pressure differential to move the internal slide laterally.

Designed for professional installation, the ICP 1173649 is engineered to withstand high-pressure environments typical of R-410A and R-22 systems. Its durable brass body and precision-machined internal components prevent bypass leakage, ensuring maximum thermal efficiency. For technicians troubleshooting a stuck reversing valve or a burnt-out 24V heat pump coil, this genuine Heil Quaker part restores original factory specifications to residential and light commercial condensing units.

• Precise Flow Control: High-integrity 4-way pilot valve design ensures reliable refrigerant redirection under full system pressure.
• OEM Compatibility: Exact fit for Heil, Quaker, Tempstar, and Comfortmaker units, eliminating field modification during replacement.
• Electrical Reliability: Included 24V coil is optimized for standard defrost board outputs, ensuring consistent engagement.
• System Efficiency: Minimizes suction-to-discharge leakage to maintain SEER and HSPF ratings.

• How do I diagnose a faulty 1173649 valve? Check for 24V at the coil terminals. If voltage is present but the valve doesn't shift, listen for the "click" of the pilot solenoid. If it clicks but the system stays in one mode, the internal slide may be mechanically seized.
• Does this include the solenoid coil? Yes, this part number specifically includes the 24V solenoid coil required for electronic actuation.
• What causes these valves to fail prematurely? Most failures are caused by physical debris in the refrigerant lines, scorched internal seals from over-heating during brazing, or a failed solenoid coil. Always use a wet rag or heat-sink paste on the valve body when installing.
