What to do if the Julabo Air Conditioner cooling compressor has overload protection?
- L
  longpeggyAug 8, 2025
  If the cooling compressor has overload protection, it could be due to several reasons: poor air circulation, small distance to walls, dirt accumulated on condenser, high ambient temperature, or frequent on/off cycles. To resolve this, ensure proper air circulation, increase the distance to walls, clean the condenser, reduce the ambient temperature, and avoid short switch-off intervals.

What to do if Julabo Air Conditioner shows a warning without a complete shutdown?

  Daniel VaughanAug 15, 2025
  If the Julabo Air Conditioner shows a warning without a complete shutdown, it could be due to several reasons. The circulator may be operating without enough bath fluid, a tube breakage may have occurred, or the float may be defective. Replenish the bath tank with the bath fluid. If there was tube breakage, replace the tubing and replenish the bath tank with the bath fluid. If the float is defect, it should be repaired by authorized JULABO service personnel. Also, reconnect the cable or eliminate the short-circuit.
