ICP Run Capacitor Kit 5 MFD 370V for RGS101SRBB0AAAA — Boot & Oval Clamp | Ships Today

Overview

This is a genuine OEM motor run capacitor kit for the ICP / Tempstar / Heil RGS101SRBB0AAAA gas furnace. It includes the capacitor boot (OEM 1171842) and the oval capacitor mounting clamp (OEM 1171552). The run capacitor provides the continuous phase shift a single-phase blower or inducer motor needs to run efficiently and at the correct torque. Rated at 5 MFD and 370V, a weak or failed capacitor is one of the most common causes of a motor that hums but will not start, overheats, or trips on thermal overload. The included boot insulates the terminals and the oval clamp secures the can to the blower housing.

Specifications

Compatibility

Engineered for the ICP RGS101SRBB0AAAA furnace and shared Tempstar, Heil, and Comfortmaker platforms that use the same blower/inducer motor capacitor assembly. Always confirm the MFD and voltage rating stamped on your existing capacitor before ordering.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter. Capacitors store a charge — discharge across the terminals with an insulated resistor before touching.
2. Access — Remove the furnace blower compartment service panel.
3. Document — Photograph all wire positions before disconnecting.
4. Remove — Loosen the oval clamp, slide out the old capacitor, and pull the boot and leads.
5. Install — Seat the new capacitor in the clamp, fit the boot, and reconnect each lead per your photo.
6. Test — Restore power and verify the motor starts smoothly and reaches full speed.

Signs You Need a Replacement

• Blower or inducer motor hums but will not spin up
• Bulging, leaking, or swollen capacitor can
• Motor overheats or trips on thermal overload
• Measured capacitance has drifted below 5 MFD
