Heil Quaker ICP 1185307 Run Capacitor

The Heil Quaker ICP 1185307 Run Capacitor is a high-performance 70/5 Microfarad 440Vac Round Dual Run Capacitor engineered for demanding HVACR applications. Designed as a direct replacement for ICP part numbers 1172163 and 1186419, this dual-section component provides the necessary phase shift to optimize AC compressor startup and maintain continuous condenser fan motor efficiency. With a 70+5 MFD capacitance rating and 440V AC tolerance, it is fully backward compatible with 370V systems, offering increased dielectric strength and thermal headroom for 1 and 3-phase motors. Utilizing heavy-edged metalized polypropylene film and a pressure sensitive interrupter (PSI) safety switch, this round-case capacitor ensures reliable torque delivery and stable microfarad output across varying ambient temperatures. Ideal for Heil, Tempstar, and Comfortmaker units, this OEM-grade component is built for technicians who prioritize precise HVAC motor capacitance and long-term system stability over generic alternatives.

• Dual Capacitance Design: Supports both the 70 MFD compressor circuit and the 5 MFD fan motor simultaneously.
• Enhanced Voltage Rating: The 440VAC rating provides superior protection against voltage surges compared to standard 370V capacitors.
• Broad ICP Compatibility: Seamlessly replaces legacy part numbers 1172163 and 1186419 across multiple equipment brands.
• Safety Field-Tested: Features a non-PCB, oil-filled design with an internal safety switch for rupture protection.
• Durable Construction: Housed in a corrosion-resistant aluminum casing with 1/4 inch quick-connect terminals for rapid field installation.

• Can I use a 440V capacitor if the old one was 370V? Yes; a higher voltage rating is a permissible upgrade that offers better heat dissipation and durability, provided the MFD ratings match exactly.
• How do I know if my 70/5 MFD capacitor has failed? Look for physical indicators like a bulging top, or electrical indicators such as a humming compressor that fails to start or "hard starting" during peak cycles.
• Will this fit my specific Heil or Tempstar model? This capacitor is a standard round 2.5-inch diameter component; verifying the MFD requirements on your unit's data plate is the best way to confirm a match.
