Why is my Quest Engineering Dry RDS 10 not removing enough water?

  Lee JohnsonAug 8, 2025
  If the Quest Engineering Other unit isn't removing as much water as you'd expect, it could be due to several reasons. The air temperature or humidity might have dropped. The humidity meter or thermometer you're using could be out of calibration. The unit might be in a defrost cycle. A dirty air filter, a defective defrost thermistor, or a low refrigerant charge could also be the cause. Check for air leaks, such as a loose cover, or consider the possibility of a defective compressor. Finally, restrictive exhaust or inlet ducting could be the culprit.

  If your Quest Engineering Other unit's compressor runs even when the POWER button is OFF, it might be due to a defective relay or a defective control board. Another potential cause is if the upper housing is not sealed to the tower.

The safety float switch might be closed, so check the pump reservoir. Other potential causes include a defective compressor capacitor, a defective compressor overload, or a defective compressor. Finally, the control board could be defective.

Why is the evaporator coil frosted on my Quest Engineering Dry RDS 10?

  Dr. Regina RobinsonAug 20, 2025
  If your Quest Engineering Other unit shows continuous evaporator coil frosting and low dehumidifying capacity, the defrost thermistor might be loose or defective. It could also indicate a low refrigerant charge, a dirty air filter or restricted airflow, or that the upper housing isn't sealed to the lower housing.

  If your Quest Engineering Other unit isn't dehumidifying, and the air mover runs continuously but the compressor only runs sporadically, it could be because the unit is in a defrost cycle, indicated by the DEFROST light being on. Alternatively, the defrost thermistor might be defective or loose, or there could be a loose connection in the compressor circuit. Other possible causes include a defective compressor overload, a defective compressor, a defective relay, or that the upper housing is not sealed to the lower housing.

  Richard BrownSep 2, 2025
  If your Quest Engineering Other unit isn't dehumidifying, the hour meter display isn't working, the compressor isn't running, and the POWER button doesn't turn ON, first ensure the unit is plugged in and that the outlet has power. If that's not the issue, a defective control board or a loose connection in the internal wiring could be the cause.
