ICP Round Run Capacitor 2.5 MFD for YJ030GA1 — OEM 1064218 | Ships Today

Overview

This OEM 2.5 MFD round run capacitor (part number 1064218) provides the steady phase shift that keeps a motor running smoothly on your ICP YJ030GA1 heat pump. Run capacitors store and release energy to maintain torque on the fan or auxiliary motor; when the capacitance drifts or the capacitor swells and fails, the motor hums but won't start, runs hot, or stops entirely. A weak 2.5 MFD capacitor is a frequent cause of a motor that struggles to spin up or trips on overload. This genuine replacement ships with its mounting clamp and is rated to the original specification for reliable, long-term operation.

Specifications

Compatibility

Direct-fit replacement for the ICP / Tempstar / Heil YJ030GA1 heat pump and related YJ030 series units that originally used capacitor 1064218. Confirm the MFD value and voltage on your existing capacitor before installing.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker, verify zero voltage with a multimeter, then discharge the capacitor across its terminals with an insulated resistor.
2. Access — Remove the electrical access panel on the condensing unit.
3. Document — Photograph the terminal wiring before removing any leads.
4. Remove — Pull the spade connectors, loosen the mounting clamp, and lift out the old capacitor.
5. Install — Secure the new 2.5 MFD capacitor with the clamp and reconnect the leads to match your photo.
6. Test — Restore power and confirm the motor spins up immediately and runs without humming.

Signs You Need a Replacement

• Motor hums but won't start spinning
• Visibly bulged, swollen, or leaking capacitor top
• Capacitance reads outside ±6% of 2.5 MFD on a meter
• Motor runs hot or trips on overload
