  If your WhisperKool Air Conditioner unit is leaking water, here's what you can check: * Ensure the Evaporator Unit (Fan Coil Unit) is level on the wall. * Inspect the drain line for clogs or kinks to ensure free water flow. * Disconnect the drain and clear out any blockages. Open the access door and check the drain for obstructions. * Correct the drain line to ensure a downward slope from the unit to the drain. * If the coil is iced, melt the ice with a blow dryer and soak up the water with a towel.

  If your WhisperKool Air Conditioner runs but doesn't cool, consider these potential issues: * Check for and remove any obstructions to ensure proper airflow. Make sure the evaporator filter, evaporator coil, and condenser coil are clean and free of debris. * If the compressor is overheating, shut the system off for 1 hour to allow it to cool. Then, turn it back on and check for cooler airflow. If the compressor runs, inspect and clean the condenser coil as a possible cause. If the problem persists, further assistance is needed.

  If your WhisperKool Air Conditioner system runs constantly, check for a leaky door seal or poor cellar insulation. Address any leaks in the door seal and ensure the cellar is properly insulated.

What causes the evaporator fan to run but the compressor not to run on my WhisperKool Air Conditioner?

  Michelle VanceSep 3, 2025
  If the evaporator fan runs but the compressor doesn't in your WhisperKool Air Conditioner, here are a few things to consider: * The system might be running an Anti-Frost cycle. If the system is maintaining the correct cellar temperature and a dripping snowflake symbol is on, no action is needed. However, if the temperature isn't correct, a dirty evaporator filter or coil may be the cause. * The system may be performing the WHM (Warmest Home Mode) function. Allow the cooling system to revert back to cooling mode. * The compressor may have overheated. Shut the system off for 1 hour to allow the compressor to cool, then turn it back on and check for cooler airflow. If the compressor runs, check for and clean the condenser coil as a possible cause.

  If your WhisperKool Air Conditioner unit is running but not cooling, there are several potential causes. First, ensure there is adequate airflow by checking that the fan is unobstructed and that the evaporator filter, evaporator coil, and condenser coil are clean and free of debris. If the compressor is overheating, shut the system off for 1 hour to allow it to cool, then turn it back on to check for cooler airflow. Clean the condenser coil if overheating repeats. If the problem persists or your system is undersized, contact Customer Service at 1-800-343-9463.

  If your WhisperKool Air Conditioner unit is leaking water, it could be due to several reasons. Ensure the evaporator unit is level to prevent leaks. Check the drain line for clogs or kinks that may be obstructing water flow. Disconnect the drain to clear any blockages, and inspect the drain for obstructions through the access door. Make sure the drain line has a downward slope from the unit to the drain. If the coil is iced, melt the ice with a blow dryer and soak up the water with a towel.

How to fix ice forming on the evaporator unit of my WhisperKool 4000 Evaporator Air Conditioner?
- T
  Travis ZimmermanNov 18, 2025
  If you notice ice forming on the evaporator unit (fan coil unit) of your WhisperKool Air Conditioner, consider the following: * The evaporator filter or coil might be dirty. Remove the filter and wash it. Clean the coil with a vacuum. For heavily soiled coils, use a spray bottle with a small amount of liquid dishwashing detergent or coil cleaner, let it sit for 5 minutes, and then flush with fresh water. * There might be a blockage in the supply or return air. Remove any obstructions. * The evaporator unit may not have completed its anti-frost sequence. Check for ice deep within the coil and melt it using a blow dryer until the coil feels warm. Use a towel to absorb any water. * Observe the ice formation pattern. If ice only forms partway up the coil face, the system could be low ...

  Carrie BauerNov 21, 2025
  If your cellar temperature is too warm when using a WhisperKool Air Conditioner, consider these possible causes and solutions: * If the temperature of the room the condensing unit exhausts to exceeds 110°F, the intake temperature needs to drop below 85°F. * If the system is undersized for the cellar, order the correct size system. * If there's a blockage in the supply and/or return air on either the Evaporator Unit (Fan Coil Unit) or the Condensing Unit, remove the obstruction. * If the Evaporator Unit (Fan Coil Unit) is mounted too low, relocate the unit so the distance from the ceiling and top of the unit is no more than 18”. * Ensure there are no air gaps around the door, and replace the door seal if it's damaged. * If the controller is set too high, lower the set point. * ...
