A biochemical incubator is a vital piece of laboratory equipment used in microbiology, agriculture, pharmaceuticals, and environmental research. Its role is to provide a stable and controlled temperature environment, essential for cultivating microorganisms, conducting biochemical reactions, and performing BOD testing.

However, like all precision instruments, even the most advanced incubators can occasionally encounter issues. Identifying and solving these problems promptly is critical for maintaining experiment accuracy and extending the life of the device.

At taihongjun.com, we specialize in manufacturing high-quality biochemical incubators and constant temperature and humidity chambers. In this guide, we’ll walk you through the most common incubator problems, their causes, and practical solutions to keep your lab running smoothly.

🔧 Common Biochemical Incubator Problems

1. Inaccurate Temperature Readings

Symptoms:

• Internal temperature doesn’t match the display.

• Fluctuations beyond acceptable tolerance.

• Delayed heating or cooling.

Possible Causes:

• Faulty temperature sensor.

• Improper calibration.

• Poor air circulation due to overcrowding.

• Worn-out or poorly sealed door gasket.

Solutions:

• Verify with an independent thermometer.

• Calibrate the controller using the user manual or professional help.

• Ensure samples are evenly spaced and not blocking airflow.

• Inspect and replace gaskets if sealing is compromised.

✅ Tip from TaiHongJun: Our biochemical incubators come with high-precision PID controllers and easy-access calibration interfaces, making adjustment quick and accurate.

2. Condensation or Moisture Build-up

Symptoms:

• Water droplets on the chamber walls.

• Moisture on stored materials.

• Fungal growth or corrosion.

Possible Causes:

• Frequent door opening.

• High internal humidity or poor ventilation.

• Faulty insulation or broken door seal.

Solutions:

• Minimize door openings during operation.

• Dry the chamber regularly.

• Check for air leaks and reseal or replace gaskets.

• Ensure the unit is not placed in a humid room.

3. Fan or Air Circulation Failure

Symptoms:

• Uneven temperature inside the chamber.

• Noise from internal fan.

• Reduced performance over time.

Possible Causes:

• Dust accumulation on the fan.

• Motor malfunction.

• Obstruction in the airflow pathway.

Solutions:

• Clean the fan blades and surrounding vents.

• Replace faulty fan motor.

• Ensure the chamber is not overloaded or blocked.

✅ TaiHongJun Advantage: Our incubators are designed with low-noise, high-efficiency circulation systems that are easy to access and clean, reducing the risk of airflow problems.

4. Controller or Display Malfunction

Symptoms:

• Unresponsive buttons.

• Flickering or blank display.

• Inaccurate settings or memory loss.

Possible Causes:

• Power fluctuations or surges.

• Aging control panel.

• Moisture intrusion.

Solutions:

• Use a voltage stabilizer to protect the electronics.

• Reboot the system and try factory reset if available.

• If damage persists, consult technical support or replace the control module.

5. Compressor or Cooling System Issues (for models with cooling)

Symptoms:

• Incubator cannot cool below ambient temperature.

• Loud compressor noise.

• Unit overheating.

Possible Causes:

• Refrigerant leakage.

• Faulty compressor.

• Dirty condenser coils.

Solutions:

• Schedule professional maintenance for refrigerant refill or leak repair.

• Clean the condenser coils regularly.

• Avoid placing the incubator near walls or in enclosed spaces to ensure airflow.

6. Power Failure or Frequent Tripping

Symptoms:

• Incubator suddenly shuts down.

• Circuit breaker trips often.

• Power indicators flicker.

Possible Causes:

• Faulty power cord or plug.

• Electrical overload.

• Internal short circuit.

Solutions:

• Check the power source and wiring.

• Use a dedicated electrical outlet.

• Consult an electrician or your supplier’s service center.
