ICP Run Capacitor Plate 10 MFD 370/440V for RGS243LSEA0AAAA — OEM 1183001 | Ships Today

Overview

This is the genuine OEM run capacitor plate (part number 1183001) for the ICP / Tempstar / Heil RGS243LSEA0AAAA gas furnace. The run capacitor stores and releases an electrical charge that keeps the blower motor running smoothly and efficiently after start-up. Rated at 10 MFD, 370/440V, it provides the steady phase shift the motor windings need to maintain torque. When a run capacitor weakens or fails, the blower may hum without starting, start slowly, overheat, or trip the motor's internal overload. A failing capacitor is one of the most common — and least expensive — causes of a furnace blower that will not run.

Specifications

Compatibility

Designed as the factory replacement for the ICP/Tempstar/Heil RGS243LSEA0AAAA furnace. The same plate is shared across many ICP family models built under the Tempstar, Heil, Comfortmaker, and related brands. Always confirm the MFD and voltage on your original capacitor before installing.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter. Discharge the old capacitor across its terminals with an insulated screwdriver.
2. Access — Remove the furnace blower compartment service panel.
3. Document — Photograph all wire connections before disconnecting anything.
4. Remove — Note the lead positions, pull the spade connectors off the capacitor terminals, and unfasten the mounting strap.
5. Install — Mount the new capacitor, reconnect the leads exactly per your photo.
6. Test — Restore power and confirm the blower starts and runs smoothly.

Signs You Need a Replacement

• Blower motor hums but will not start
• Bulging, leaking, or burnt capacitor housing
• Blower starts slowly or cuts out under load
• Motor overheats or trips its internal overload
