At the core of every life science lab, the familiar hum of incubator shakers can be heard throughout. But when that hum falters, it can disrupt critical research. The guide below highlights common issues and solutions to keep incubator shakers – and experiments – on track.

My Shaker is not Operating

Symptoms: The unit power is on, but the shaker platform remains still

Possible Causes:

• A worn or broken drive belt
• Motor failure or obstruction
• Electrical disconnection or blown fuse

Troubleshooting:

• Check the Drive Belt: A broken or slipping belt can halt movement. Inspect and schedule for replacement if necessary.
• Listen to the Motor: Check for any unusual noises; a faulty motor may need professional attention.

Note: If the motor or belt shows signs of wear or damage, it’s best to consult a service engineer to avoid further complications.

My Shaker Won’t Hold the Right Temperature

Symptoms: The incubator fails to maintain the set temperature

Possible Causes:

• Faulty or aging temperature sensors
• Compromised door seal
• Overloaded chamber restricting air circulation

Troubleshooting:

• Verify Settings: Ensure the temperature is correctly set and that over-temperature protection isn’t engaged
• Allow Stabilization: After setting a new temperature, give the unit time to stabilize before use
• Calibrate Sensors: Schedule calibration to ensure accurate readings

Note: Persistent temperature issues may indicate a malfunctioning heating element or sensor, requiring professional service.

My Shaker is Making Unusual Noises and Vibrations

Symptoms: The shaker produces excessive noise or vibrations during operation

Possible Causes:

• Unbalanced or unevenly distributed samples
• Loose bolts or platform components
• Worn bearings misaligned drive system

Troubleshooting:

• Balance the Load: Arrange flasks symmetrically
• Inspect for Obstructions: Foreign objects or loose parts can lead to noise; remove any debris

Disclaimer: When inspecting for debris, always exercise caution. Broken tubes or glass shards may be present, posing risk of injury. Always ensure you are wearing the proper PPE for the job.

Note: If vibrations persist, the issue may stem from internal components, prompting expert evaluation.

My Incubator is Displaying Error Messages

Symptoms: The control panel is unresponsive or displays error messages

Possible Causes:

• Software glitches or firmware issues
• Loose or damaged wiring connections
• Power supply inconsistencies

Troubleshooting:

• Power Cycle: Turn the unit off and on to reset the system
• Check Connections: Ensure all cables are securely connected
• Consult the Manual: Refer to your shaker’s user manual for specific error code troubleshooting and solutions

Note: Persistent control issues may require software updates or hardware repairs, which are best performed by service engineers.

My Shaker is Contaminated

Symptoms: Visible residue or microbial growth inside the chamber

Possible Causes:

• Infrequent cleaning or improper cleaning agents
• Spills not addressed promptly
• Poor air circulation or high humidity

Troubleshooting:

• Immediate Cleaning: Use a neutral cleaning agent to remove spills and residue
• Disinfection: Work with a qualified decontamination provider to sanitize the instrument and surrounding areas.

Note: Scheduling regular cleaning, or preventative cleaning, helps limit contamination and maintain a sterile lab environment.
