Why is my Hydrofarm ACTIVE AQUA AACH50 performance decreased or there is no refrigeration?

  There could be several reasons why your Hydrofarm Chiller's performance has decreased, or why it's not refrigerating at all: * The fan might not be working, in which case you should return it to the place of purchase. * The set temperature may be higher than the aquarium water temperature; try resetting the temperature. * The air inlet or outlet could be clogged. Clean them using a brush or vacuum cleaner.

  If your Hydrofarm Chiller is cycling on and off, it could be due to a few reasons. First, the voltage and/or frequency might be incorrect, so apply the correct power source. Second, the chiller might be in protection mode. In this case: 1. Check if the water circulation is normal. 2. Check if the fan and the chiller dissipate heat normally. 3. Wait for 3 minutes, and the unit will automatically turn on again.
