Is Your Fan Facing These Issues?
Identify the symptoms before they damage the motor permanently.
Loud Noise / Grinding
The “Khrrrr” sound indicates the bushes are dry or worn out. The shaft is grinding against metal.
Jammed / Stuck
The motor hums but doesn’t spin unless you push it with a stick. This is a lubrication failure.
Slow Speed
Fan runs very slowly even on ‘High’. Usually caused by a weak capacitor or dust buildup.

Complete Guide to Fan Motor Maintenance
Introduction: Understanding the Mechanics
While “Motor Winding” deals with the electrical coils inside, Fan Motor Repair usually refers to the mechanical components that allow the motor to spin. In 80% of cases, the motor winding is perfectly fine, but the mechanical parts like the Bush, Shaft, or Capacitor have failed.
Fixing these mechanical issues is significantly cheaper (₹300-₹500) than rewinding the whole motor (₹1200+). At CoolFix Vadodara, we always check mechanical faults first to save you money.
Part 1: The Bush vs. Bearing Difference
Most ceiling fans use Ball Bearings. However, 90% of Air Cooler motors use Sintered Bushes.
- What is a Bush? It is a small cylinder made of compressed metal powder (bronze/iron). It is porous, meaning it soaks up oil like a sponge.
- How it works: The motor shaft spins inside this bush. A felt pad soaked in oil surrounds the bush, constantly feeding it lubrication.
- Why it fails: In Vadodara’s dry heat, the oil evaporates. Once dry, the metal shaft rubs against the metal bush. This friction creates heat, “seizing” the motor and making a loud screeching noise.
Part 2: The “Speed Boosting” Capacitor
The Capacitor (or Condenser) is the small cylindrical battery-like object connected to the motor. Its job is to provide the electrical “torque” to start the heavy fan blade.
Signs of a Weak Capacitor:
- Fan spins very slowly even on full speed.
- Fan needs a “push” by hand to start spinning.
- Motor gets hot but air throw is weak.
Note: Replacing a capacitor is a cheap fix (₹150) that can make an old cooler feel brand new.
Part 3: Fan Blade Balancing
Does your cooler “walk” or shake violently across the room? This is caused by an Unbalanced Fan Blade.
If one blade breaks or bends, the center of gravity shifts. As the motor spins at 1400 RPM, this imbalance creates massive vibration. This vibration destroys the motor bushes and cracks the cooler body. Solution: Never try to glue a broken blade. Always replace the entire fan blade set.
DIY Maintenance Tips
- Lubrication Port: Look for small red/yellow caps on top of the motor. Put 5-10 drops of non-sticky oil (like sewing machine oil) every month.
- Clean the Blades: Dust accumulation on the edges of the fan blades adds weight and drag. Wipe them clean for better speed.
- Check Alignment: Ensure the motor is sitting straight on its mounting brackets. A tilted motor puts uneven pressure on the shaft.
Motor Jammed Tight?
