ICP Run Capacitor with Boot & Clamp for RGX036KMCA0AAA — 7.5 MFD 370V | Ships Today

Overview

This OEM single-run capacitor kit keeps the blower motor in your ICP RGX036KMCA0AAA gas furnace running at full torque. Rated at 7.5 MFD and 370 volts, the capacitor provides the phase shift a PSC blower motor needs to start and run efficiently. The kit ships with OEM part 1171842 (capacitor boot) and 1171552 (oval mounting clamp) so the assembly seats and seals exactly as the factory intended. A failing run capacitor is one of the most common causes of weak airflow, motor humming without spin, and overheating service calls — replacing it restores rated CFM and protects the motor windings.

Specifications

Compatibility

Engineered for the ICP / Tempstar / Heil RGX036KMCA0AAA gas furnace and other RGX-series models that use a 7.5 MFD blower run capacitor. Always confirm the MFD and voltage stamped on your existing capacitor before installing.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage at the capacitor terminals with a multimeter; capacitors hold a charge.
2. Access — Remove the furnace blower compartment service panel.
3. Document — Photograph all wire positions before disconnecting.
4. Remove — Discharge the old capacitor across its terminals with an insulated resistor, label and remove the leads, then loosen the mounting clamp.
5. Install — Seat the new capacitor in the oval clamp, fit the protective boot, and reconnect the leads per your photo.
6. Test — Restore power and confirm the blower starts promptly and runs at full speed.

Signs You Need a Replacement

• Blower motor hums but will not start spinning
• Weak or reduced airflow from supply registers
• Bulged, leaking, or burst capacitor canister
• Motor overheats and trips on thermal overload
