Checked the Midco power burner for the North paint booth for burner failure alarm. Cleaned the pilot assembly, flame rod and burner to increase the flame signal. Verified operation after repairs. Also checked the Hastings direct fired air make up for the South paint booth for vibration after the customer heard a loud noise. Found the drive end side blower wheel with the wheel missing vanes causing the vibration. Researched the parts and quoted the repairs.
