Overview
This OEM blower motor module is the direct factory replacement for ICP/Tempstar/Heil model WAPM304A2 air handlers. Rated at 1/3 HP and 230V, it drives the indoor blower wheel that moves conditioned air through your duct system on both heating and cooling cycles. Replaces ICP part numbers 1190331 (Motor Module 1/3 HP 230V) and 1185023 (Blower Motor 1/3 HP). When the blower motor fails, you'll notice weak or no airflow at the registers, a humming motor that won't spin, overheating and tripped limit switches, or a unit that runs but never reaches setpoint. Using the OEM module guarantees correct shaft size, rotation, mounting, and electrical match so the system runs quietly and efficiently.

Compatibility
Designed specifically for the ICP/Tempstar/Heil WAPM304A2 air handler. This motor module is a guaranteed fit for that model and may also service related WAPM-series air handlers using the same 1/3 HP 230V blower assembly. Always confirm the part number on your existing motor matches 1190331 or 1185023 before installing.
Installation Guide
- Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter before touching any wiring.
- Access — Remove the air handler's blower compartment service panel.
- Document — Photograph all motor wire connections and the blower wheel position before disconnecting anything.
- Remove — Disconnect motor leads, loosen the blower wheel set screw, slide the wheel off, and unbolt the old motor from the mounting band.
- Install — Mount the new motor module, reinstall the blower wheel at the documented depth, tighten the set screw on the shaft flat, and reconnect wiring per your photo.
- Test — Restore power and verify the blower spins up smoothly, ramps to speed, and delivers strong airflow at the registers.
Signs You Need a Replacement
