In the process of using a biochemical incubator, we may encounter situations where the incubator cannot cool down. Below are the reasons and solutions for the problems caused by the biochemical incubator:

1) All operations in the biochemical incubator are effective, heating is normal, and cooling is not possible.

Inspection method: First, check if the refrigeration indicator light is on. If it is on, check if the refrigeration relay has output. If there is no output, it is mostly due to the relay's contacts falling off or being damaged during frequent operation. Replace it. If there is output, check if the compressor is running. If it is running, refrigerant leakage or compressor cylinder wear may occur due to prolonged use, with the former being more common. Solution: Find the leakage point and repair it. The latter method only involves replacing the compressor.

2) All operations of the biochemical incubator are effective, but the cooling indicator light is not on and the heating is normal, unable to cool.

Solution: This situation is often caused by human error, simply enter the internal parameters to adjust CL.
