326100-401 – INDUCER COOLING WHEEL

This small cooling wheel sits on the inducer motor shaft and helps keep the motor from overheating during operation. If the wheel is cracked, broken, or missing, the inducer motor can overheat and fail prematurely. An inexpensive part that can save you from a costly motor replacement.

My furnace ignites then shuts off — is the inducer bad?

Usually no. That symptom is almost always the pressure switch — the inducer spins fine but the switch doesn't see enough draft. Check the condensate drain (plug = water backs up, switch won't close). Replace the hose if it's brittle. Inducer assembly is rarely the actual failure.

How do I test an inducer motor?

Pull the assembly, spin the wheel by hand — should turn freely, no grinding. Apply 120V directly to the motor leads (skip the board) — should run smoothly. If it doesn't spin, draws weak airflow, or bearings whine, replace.

Will an aftermarket inducer fit my OEM equipment?

Most aftermarket assemblies labeled 'DIRECT REPLACEMENT' fit without modification — same wheel diameter, same motor mount, same harness. Bring the old assembly in to verify before driving home with it.

How long should an inducer motor last?

8-15 years typical. The motor itself outlasts the bearings — bearing failure is the usual mode. Sealed-bearing motors last longer than open-bearing.
