1. Power Failure or Failure to Start

Symptoms: No display, no sound, no movement
Causes: Disconnected power cord, blown fuse, faulty switch or wiring
Solutions:

• Check and secure the power connection

• Test the outlet with another device

• Replace blown fuses and reset circuit breakers

• Replace faulty power switch or consult a technician for internal wiring issues

2. Excessive Vibration

Symptoms: Shaking, wobbling, strange noises
Causes: Unbalanced load, damaged rotor, uneven surface
Solutions:

• Distribute samples evenly

• Ensure centrifuge is placed on a level surface

• Inspect and replace a worn or cracked rotor

• Remove any foreign objects from the rotor chamber

3. Abnormal or Loud Noise

Symptoms: Grinding, squealing, or rattling sounds
Causes: Worn bearings, loose parts, internal debris
Solutions:

• Tighten all components

• Replace worn bearings

• Clean the interior of the centrifuge

4. Inconsistent or Inaccurate Speed

Symptoms: Fluctuating RPM, failure to reach set speed
Causes: Motor malfunction, control panel error, tachometer failure
Solutions:

• Calibrate the speed controller

• Check motor performance

• Replace or repair faulty sensors

5. Overheating

Symptoms: Hot surfaces, automatic shutdown
Causes: Blocked ventilation, failed cooling system, continuous use
Solutions:

• Clean vents and fans

• Allow cooldown intervals between cycles

• Replace or repair cooling components

6. Rotor Damage

Symptoms: Cracks, unusual vibration, imbalance
Causes: Metal fatigue, improper handling or installation
Solutions:

• Regularly inspect the rotor for wear

• Follow correct mounting procedures

• Replace damaged rotors immediately

7. Lid or Door Malfunction

Symptoms: Unable to open/close lid, lid error prevents operation
Causes: Faulty latch, broken interlock sensor, obstruction
Solutions:

• Replace broken latch mechanisms

• Realign or clean lid components

• Check interlock system functionality

8. Error Messages or Alarms

Symptoms: Display errors, beeping alarms
Causes: Calibration faults, sensor issues, software glitches
Solutions:

• Use the user manual to decode error codes

• Restart the centrifuge

• Contact the manufacturer if the problem persists

9. Sample Leakage or Spillage

Symptoms: Wet rotor, fluid on chamber surfaces
Causes: Overfilled tubes, cracked containers, worn seals
Solutions:

• Do not overfill tubes

• Use proper tube adapters

• Replace damaged tubes and seals

10. Poor Sample Separation

Symptoms: Incomplete separation, mixed sample layers
Causes: Incorrect speed/time settings, unbalanced rotor, poor sample prep
Solutions:

• Adjust RPM and spin time according to protocol

• Ensure even tube loading

• Follow recommended sample preparation steps
