ICP Run Capacitor for WFSR080B048A1 — 25 MFD 370V Oval | Ships Today

Overview

This OEM oval run capacitor fits the ICP/Tempstar/Heil WFSR080B048A1 gas furnace. Rated 25 MFD at 370V, it delivers the consistent phase shift that lets the blower motor start cleanly and run efficiently. A run capacitor charges and discharges on each cycle to keep the motor torque steady; as it ages it loses capacitance, forcing the motor to draw more current and run hot. Typical failure signs include a blower that hums without starting, a hot or short-cycling motor, or a bulged capacitor. This kit pairs OEM capacitor 1176131/1185806 with mounting strap 1014315 for a complete, secure install.

Specifications

Compatibility

Direct-fit replacement for the ICP/Tempstar/Heil WFSR080B048A1 furnace and other ICP-family blower assemblies specifying a 25 MFD / 370V oval capacitor. Confirm the MFD and voltage 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. Discharge the capacitor with an insulated resistor before touching terminals.
2. Access — Remove the furnace blower compartment service panel.
3. Document — Photograph all wire connections before disconnecting.
4. Remove — Loosen the mounting strap, note terminal markings, and pull the spade connectors off the old capacitor.
5. Install — Secure the new capacitor with the included oval strap and reconnect each wire to its matching terminal per your photo.
6. Test — Restore power and confirm the blower starts promptly and runs without humming or overheating.

Signs You Need a Replacement

• Blower motor hums but does not start
• Bulged, swollen, or leaking capacitor can
• Motor runs hot or trips on thermal overload
• Measured capacitance is outside the ±6% tolerance of 25 MFD
