ICP Blower Run Capacitor for WFHR080B036A1 — 7.5 MFD 370V | Ships Today

Overview

This is the OEM run capacitor (part #1177197) for the ICP/Tempstar/Heil WFHR080B036A1 gas furnace. The run capacitor provides the phase shift the PSC blower motor needs to start and run efficiently, delivering steady torque so the indoor blower pushes conditioned air through the ductwork. This 7.5 MFD, 370-volt oval capacitor ships with its factory mounting strap (#1170643) to hold it securely in the blower compartment. As a capacitor ages, its microfarad rating drifts low — the blower then draws excess amperage, runs hot, hums without starting, or trips on overload, leaving you with no airflow during a heat call.

Specifications

Compatibility

Engineered as a direct OEM replacement for the ICP WFHR080B036A1 furnace and shared platforms sold under the Tempstar, Heil, and Comfortmaker brands. Confirm your existing capacitor reads 7.5 MFD / 370V before ordering, as some furnace variants use a different blower motor.

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
