Why is my PolyScience Chiller not cooling properly?

  Jason TaylorJul 31, 2025
  If your PolyScience Chiller isn't cooling effectively, there might be a few reasons. First, check for dust buildup on the air filter or condenser and clean them if needed. Also, make sure the air ventilation screens aren't blocked. Ensure that the heat load isn't exceeding the chiller's capacity. High ambient air temperature or incorrect line voltage could also be factors; address these as necessary.

  If your PolyScience Chiller isn't circulating fluid properly, start by checking the fluid level in the reservoir and add more fluid if it's low. Then, inspect the circulating system for any blockages and remove them. If the pump isn't running, it might need to be replaced.

Why does the pump cycle on and off at startup on my PolyScience Chiller and EFL flashes on display?

  If the PolyScience Chiller pump cycles on and off at startup and 'EFL' flashes on the display, it indicates a no-flow condition. This is often due to insufficient fluid in the reservoir or a blockage in the circulating system. Add fluid to the reservoir as needed and remove any blockages.

How to improve insufficient circulation in PolyScience Chiller?

  Michele SparksAug 16, 2025
  If your PolyScience Chiller has insufficient circulation, the fluid viscosity might be too high; consider replacing it with a lower viscosity fluid. Also, check if the external tubing diameter is too small and replace it with larger diameter tubing if necessary. Restrictions in the fluid lines or low line voltage could also be contributing factors; check and correct these as required.

What to do if PolyScience Chiller does not run, but three decimal points appear on the temperature display?
- D
  Daniel ParksAug 20, 2025
  If your PolyScience Chiller unit does not run and three decimal points appear on the temperature display (two on pressure/flow rate), it's likely in Standby mode. Press the Power Button on the front panel to exit Standby mode.

  If the PolyScience Chiller isn't running and the digital displays are blank, ensure the electrical cord is securely connected to a working outlet. Also, check that the Power Switch/Circuit Breaker on the rear of the unit is turned ON.
