ICP Blower Run Capacitor for WFHR080B048A1 — 7.5 MFD 370V | Ships Today

Overview

This is the OEM run capacitor (part #1177197) for the ICP/Tempstar/Heil WFHR080B048A1 gas furnace. The run capacitor provides the phase shift the PSC blower motor needs to start and run efficiently, delivering a steady torque boost so the indoor blower moves conditioned air through the ductwork. This 7.5 MFD, 370-volt oval capacitor is paired with its factory mounting strap (#1170643) to keep it securely seated in the blower compartment. When a run capacitor weakens or fails, the blower motor draws excess amperage, runs hot, hums without starting, or trips the limit — leaving you with no airflow even though the furnace is calling for heat.

Specifications

Compatibility

Engineered as a direct OEM replacement for the ICP WFHR080B048A1 furnace and shared platforms sold under the Tempstar, Heil, and Comfortmaker brands. Always confirm your existing capacitor reads 7.5 MFD / 370V before ordering, as some furnace variants ship with different blower motors.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter. Capacitors hold a charge — discharge across the terminals with an insulated resistor before touching.
2. Access — Remove the blower compartment service panel.
3. Document — Photograph all wire connections before disconnecting.
4. Remove — Loosen the mounting strap, slide out the old oval capacitor, and pull the spade terminals.
5. Install — Mount the new capacitor in the strap, reconnect each lead per your photo, and confirm a snug fit.
6. Test — Restore power and verify the blower spins up smoothly and quietly.

Signs You Need a Replacement

• Blower motor hums but won't start
• Bulged, leaking, or burst capacitor canister
• Weak or intermittent airflow from the registers
• Motor overheats or trips on thermal overload
