B1368016S – BLOWER WHEEL (10″ x 8″, CW, CONVEX)

If your indoor unit runs but produces weak or no airflow, the blower wheel may be worn, cracked, or coated in dust. This 10×8 CW convex wheel is an OEM Goodman replacement that also fits several Carrier/Bryant units.

Specs: 10″ diameter x 8″ width, clockwise rotation, convex blade design, 1/2″ bore

Replaces: B1368016S, 667037R, 703014, BW43016, D6723302S, LA22LA014, LA22LA015, LA22LA034

Fits: Goodman/Amana furnaces and air handlers; Carrier/Bryant units using LA22LA014, LA22LA015, or LA22LA034

Fits these models

• Universal aftermarket direct-drive blower wheel (squirrel cage) -- fits residential furnaces and air handlers with matching diameter / width / rotation / blade profile
• Common applications: Rheem RH/RA series, Goodman ARUF/AWUF, Trane TWE/4TEE, Carrier FB4A/FE4A, York TG9/TM9, Lennox CB29/CBA38
• Verify ALL 4 specs match your existing wheel: diameter (9"-12"), width (6"-12"), rotation (CW or CCW from drive end), and blade profile (concave forward-curved vs convex)

My airflow seems weak -- is it the blower wheel?

Almost certainly not. The blower wheel is rarely the cause of low airflow. The real culprits, roughly in order of how often we see them: 1. Dirty filter -- clogged filter = the blower can't pull enough air through it. Replace the filter; many systems recover immediately. 2. Dirty evaporator coil -- caked dust on the indoor coil blocks airflow even with a clean filter. Pull the access cover and inspect; foaming coil cleaner restores most coils. 3. Undersized or restricted ductwork -- too few returns, undersized return drop, kinked flex duct, closed-off supply registers. Static-pressure measurement at the air handler diagnoses this. 4. Motor problems -- bad run cap (most common motor issue), bad bearings, dying ECM module. Check the cap before condemning the motor. 5. Wheel is actually broken -- cracked, missing balance clips, hub spun loose on the shaft. Visible damage on inspection.

How does a blower wheel fail?

Blower wheels typically fly apart over time. The cause is usually long-term vibration from an out-of-balance condition (missing balance clips, dirt buildup on one side of the wheel) or from running with too much accumulated dirt. The blades crack or break free, the hub spins loose, or one side of the wheel separates. Visible damage = real replacement.

How do I tell CW vs CCW rotation?

Look at the drive end of the motor (the end with the shaft sticking out). Watch which way the wheel turns when the blower runs. CW = clockwise as you face the shaft end. CCW = counter-clockwise. Wrong rotation = no airflow / reversed airflow.

What's the difference between concave and convex blades?

Concave (forward-curved) blades scoop air more aggressively -- common on residential furnace blowers, higher CFM at lower RPM. Convex (backward-curved or specific OEM profile) blades are more efficient at higher static pressures -- common on package units and some commercial applications. Match what your unit was designed for.

Why is my new wheel vibrating?

Out-of-balance wheel or bent hub. Stop the blower immediately -- vibration destroys motor bearings fast. Check for: bent blade tips (impact damage during install), missing or moved balance clips (small metal weights on individual blades), loose hub set-screw, or hub mounted on the round part of the shaft instead of the flat. Bring it back; we'll exchange.

How do I install a blower wheel correctly?

1. Slide the wheel onto the motor shaft, set-screw flat aligned with the FLAT spot on the shaft. 2. Position the wheel so its inlet edge is centered on the blower housing inlet ring. 3. Apply blue thread-locker, torque the set-screw to spec. 4. Spin by hand -- should turn freely with NO wobble or rub against the housing. 5. Power up briefly to verify rotation matches the arrow stamped on the hub.
