Engineered for efficiency and reliability, this \u003cstrong\u003e35 amp 24v contactor\u003c\/strong\u003e serves as a direct \u003cstrong\u003eOEM replacement part\u003c\/strong\u003e for International Comfort Products (ICP) equipment, including \u003cstrong\u003eHeil, Tempstar, and Comfortmaker\u003c\/strong\u003e units. This specific model features a \u003cstrong\u003esingle-pole configuration\u003c\/strong\u003e with a shunt, managing the electrical load for compressors and condenser fan motors while reducing arcs and pitting on the contact surfaces.\u003c\/p\u003e\n\n\u003cp\u003eBuilt to handle a \u003cstrong\u003e35A resistive load\u003c\/strong\u003e and approximately 25-30 FLA (Full Load Amps), the \u003cstrong\u003eICP 1050839\u003c\/strong\u003e utilizes a 24V coil to actuate the circuit. Technicians often source this part when diagnosing a \u003cstrong\u003estuck AC contactor\u003c\/strong\u003e or a failing \u003cstrong\u003econdenser contactor\u003c\/strong\u003e 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 \u003cstrong\u003egenuine ICP part\u003c\/strong\u003e, you ensure optimal switching and prevent premature failure of more expensive system components like the compressor.\u003c\/p\u003e\n\n\u003ch4\u003eKey Benefits\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOEM Compatibility:\u003c\/strong\u003e Precision engineered for \u003cstrong\u003eHeil Quaker\u003c\/strong\u003e, \u003cstrong\u003eComfortmaker\u003c\/strong\u003e, and \u003cstrong\u003eTempstar\u003c\/strong\u003e condensers, ensuring a perfect physical and electrical fit.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnhanced Durability:\u003c\/strong\u003e Rated for a \u003cstrong\u003e35 amp load\u003c\/strong\u003e, providing robust switching for residential and light commercial \u003cstrong\u003eair conditioning units\u003c\/strong\u003e.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLow Voltage Control:\u003c\/strong\u003e Operates on a standard \u003cstrong\u003e24V coil\u003c\/strong\u003e, compatible with most residential \u003cstrong\u003eHVAC control circuits\u003c\/strong\u003e and thermostats.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSilver Cadmium Oxide Contacts:\u003c\/strong\u003e Designed to resist welding and minimize pitting during high-amperage startup cycles, extending the operational life of the switch.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompact Design:\u003c\/strong\u003e A \u003cstrong\u003e1-pole with shunt\u003c\/strong\u003e design simplifies wiring by maintaining a constant path for one leg of the power while switching the other.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eCommon Questions\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this 35 amp contactor to replace a 25 amp or 30 amp unit?\u003c\/strong\u003e\u003cbr\u003e\nYes, in HVAC applications, you can typically \"size up\" the amperage rating of a contactor. Using a \u003cstrong\u003e35A contactor\u003c\/strong\u003e to replace a lower-rated 25A unit provides a higher safety margin and can improve longevity, provided the \u003cstrong\u003e24V coil voltage\u003c\/strong\u003e and physical dimensions match.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat are the signs that my ICP 1050839 contactor needs replacement?\u003c\/strong\u003e\u003cbr\u003e\nCommon failure symptoms include a \"chattering\" noise, visible pitting or carbon buildup on the silver contacts, or the \u003cstrong\u003eAC compressor not turning on\u003c\/strong\u003e 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between a 1-pole and a 2-pole contactor?\u003c\/strong\u003e\u003cbr\u003e\nThis \u003cstrong\u003e1-pole contactor\u003c\/strong\u003e 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003c\/p\u003e\u003ch1 id=\"cancel-return-note\" class=\"text-important text-bold\"\u003e\u003cspan style=\"color: #ff2a00;\"\u003eItem is Non Cancelable \/ Non Returnable\u003c\/span\u003e\u003c\/h1\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
