The Heil Quaker ICP 1050839 Contactor is a heavy-duty, 1-pole electrical switching solution designed for high-demand HVAC systems. Engineered for efficiency and reliability, this 35 amp 24v contactor serves as a direct OEM replacement part for International Comfort Products (ICP) equipment, including Heil, Tempstar, and Comfortmaker units. This specific model features a single-pole configuration with a shunt, managing the electrical load for compressors and condenser fan motors while reducing arcs and pitting on the contact surfaces.

Built to handle a 35A resistive load and approximately 25-30 FLA (Full Load Amps), the ICP 1050839 utilizes a 24V coil to actuate the circuit. Technicians often source this part when diagnosing a stuck AC contactor or a failing condenser contactor that prevents the outdoor unit from engaging. Its 1/4-inch quick-connect terminals ensure a streamlined installation for contractors in the field, maintaining the original system's performance and sound quality standards. By replacing a pitted or chattering unit with this genuine ICP part, you ensure optimal switching and prevent premature failure of more expensive system components like the compressor.

Key Benefits

• OEM Compatibility: Precision engineered for Heil Quaker, Comfortmaker, and Tempstar condensers, ensuring a perfect physical and electrical fit.
• Enhanced Durability: Rated for a 35 amp load, providing robust switching for residential and light commercial air conditioning units.
• Low Voltage Control: Operates on a standard 24V coil, compatible with most residential HVAC control circuits and thermostats.
• Silver Cadmium Oxide Contacts: Designed to resist welding and minimize pitting during high-amperage startup cycles, extending the operational life of the switch.
• Compact Design: A 1-pole with shunt design simplifies wiring by maintaining a constant path for one leg of the power while switching the other.

Common Questions

Can I use this 35 amp contactor to replace a 25 amp or 30 amp unit?
Yes, in HVAC applications, you can typically "size up" the amperage rating of a contactor. Using a 35A contactor to replace a lower-rated 25A unit provides a higher safety margin and can improve longevity, provided the 24V coil voltage and physical dimensions match.

What are the signs that my ICP 1050839 contactor needs replacement?
Common failure symptoms include a "chattering" noise, visible pitting or carbon buildup on the silver contacts, or the AC compressor not turning on despite the thermostat calling for cooling. If you measure 24V at the coil but the contacts do not pull in, the coil is likely open.

What is the difference between a 1-pole and a 2-pole contactor?
This 1-pole contactor breaks only one leg of the 240V power supply (typically L1), while the other leg (L2) remains connected through a shunt. This is common in residential units to allow for crankcase heaters to stay energized. Always verify your wiring schematic before swapping pole counts.
