I really appreciate how honest and efficient this company is. They identified the problem quickly and fixed it without unnecessary charges. I would definitely recommend them!

Aircon Fan Motor Repair in Singapore
A failed fan motor means no airflow — either from the indoor unit into the room, or across the outdoor condenser coil. We diagnose whether the fault is the motor itself, the capacitor, or the control board before replacing anything.
How we approach fan motor issues
Check the cheap fixes first
A failed capacitor or a fouled blower wheel causes the same symptoms as a dead motor. We check both before recommending a motor replacement.
Matched to original specification
Replacement motors are matched to the original speed, mounting, and rotation. A wrong-spec motor causes noise, vibration, or poor cooling.
Test run before leaving
After any motor or capacitor replacement, we run the unit and confirm airflow, noise level, and cooling performance before signing off.
Signs of a fan motor problem
These symptoms suggest a fan motor issue. The fault could be the motor, its capacitor, or the board signal driving it.
- Indoor unit powers on but no air comes out of the louvers
- Weak airflow that does not improve after cleaning
- Loud rattling, scraping, or grinding from the indoor unit
- Outdoor fan not spinning when the unit is running
- Outdoor unit overheating and shutting down on protection
- Fan runs intermittently or at the wrong speed
How fan motor diagnosis works
We test the motor, its capacitor, and the board signal to isolate the fault. A motor replacement is only recommended when the motor itself has failed.
1. Visual and mechanical check
We check the fan blade for fouling, the motor bearings for play or noise, and the mounting for looseness. Some fan noise is caused by a dirty blower wheel, not a failed motor.
2. Electrical test
We test the motor winding resistance, capacitor value, and board output to confirm whether the motor is receiving the correct signal and power.
3. Diagnosis and recommendation
We confirm whether the fault is the motor, capacitor, board, or a combination. Capacitor replacement is significantly cheaper than a motor swap.
4. Repair or replacement
The agreed repair is carried out. Motor replacements are matched to the original specification — speed, mounting, and rotation direction.
5. Test run
The unit is run and checked for correct airflow, noise level, and temperature performance before the job is signed off.
Pricing
Cost depends on whether the fault is the motor, capacitor, or board. Indoor and outdoor motors are priced differently based on type and availability.
- Diagnostic visit covers motor, capacitor, and board checks
- Capacitor replacement is the cheapest outcome
- Motor cost depends on unit brand, capacity, and motor type
- No parts are ordered until you agree to the quote
Booking and visit timing
Diagnosis is done on the first visit. If the motor needs replacing, sourcing time depends on the brand and model.
- Diagnostic visit typically completed within an hour
- Capacitor swap can be done on the same visit
- Common motor models may be available for same-day replacement
- Less common motors may take a few days to source
Indoor vs outdoor fan motor
The indoor blower fan and outdoor condenser fan serve different functions and fail in different ways.
- Indoor blower — pushes cooled air into the room through the louvers
- Outdoor condenser fan — pulls air across the condenser coil to reject heat
- Indoor motor failure → no airflow, unit may ice up
- Outdoor motor failure → compressor overheats and shuts down on protection
- Indoor motors are typically smaller and easier to source
- Outdoor motors are exposed to weather and fail from corrosion or bearing wear
Common fan motor faults
These are the faults we see most often in residential split systems.
- Bearing wear — motor runs but makes a grinding or rattling noise
- Winding failure — motor does not start, no resistance on test
- Capacitor failure — motor hums but does not spin, or runs slowly
- Blower wheel fouling — heavy buildup causes vibration and reduced airflow
- Board fault — motor receives no signal or intermittent signal
When fan motor replacement may not be the right call
Not every airflow problem is a motor fault. These situations should be checked before replacing the motor.
- Dirty filter or coil restricting airflow → service first
- Blower wheel heavily fouled → chemical wash may restore airflow
- Louver motor stuck → louver mechanism, not fan motor
- Unit not powering on at all → board or power supply issue
What customers say
Highly professional and efficient service! The technicians arrived on time, performed a thorough cleaning, and fixed my aircon issue. Honest pricing, no hidden charges.

Initially engaged another company to look into the issue with our aircon but was quoted a much higher price. Snowflake clearly explained the issue and what needs to be done, and recommended possible solutions based on their expertise.
