How to Test if a BP28 Blower is Bad?
If you suspect your BP28 blower is malfunctioning, there are several tests you can perform to confirm whether or not it is bad:
Visual Inspection
Closely examine the blower housing, blades, and motor for signs of damage. Cracks, excessive wear, or overheating can indicate issues.
Spin Test
With the power disconnected, manually spin the blower wheel. It should rotate freely with minimal resistance. Locked up or grinding blades signify a damaged bearing.
Voltage Test
Using a multimeter, check the power supply connections to the blower while switched on. No voltage means a wiring, switch, or connection failure.
Amp Draw Test
Connect the multimeter in series with the blower power supply wire. Measure the current draw and compare to the nameplate rating. Too little amperage could mean a bad motor winding.
Burnout Test
Disconnect and isolate the blower motor wires. Connect a 9-volt battery to the motor leads. If the motor does not spin, its windings are likely burned out.
Bearing Test
With power on, place a screwdriver tip on the motor casing and handle end to your ear. Excessive noise or grinding sounds indicate worn bearings.
If tests reveal electrical or mechanical defects, the BP28 blower will need to be repaired or replaced. Following proper blower maintenance procedures can maximize the lifespan.
How to Increase Airflow from a BP28 Blower?
If your BP28 blower is not moving enough air, there are several adjustments you can make to improve airflow:
Check for Restrictions
- Make sure air filter is clean and unobstructed.
- Confirm ductwork is clear with no blockages.
- Verify blower wheel spins freely without rubbing housing.
Increase Blower Speed
- Check if blower speed control can be adjusted higher.
- Swap pulleys to change speed on belt drive blowers.
- Modify wiring to bypass any speed controls present.
Improve Ductwork
- Seal any air leaks in duct joints with mastic.
- Ensure duct sizes meet recommended air volume capacity.
- Smooth out any sharp bends or elbows that cause turbulence.
Upgrade Blower
- Replace with larger blower designed to move more CFM.
- Install blower with higher horsepower motor.
- Convert to high static pressure blower for dense ductwork.
Optimizing the clearances around the blower, upgrading ducts, increasing speed, or replacing the blower with a larger model can improve CFM. Always take safety precautions when modifying electrical or ductwork.
