Dehumidifier runs continuously and never reaches the set humidity.

Safety first: Ensure the unit has adequate clearance and is not overheating.

Steps to improve performance:

• Check room size: Compare the dehumidifier's capacity (pints per day) to the room size and moisture level. A small unit may not handle a very wet basement.
• Reduce moisture sources: Fix plumbing leaks, cover open sump pits, and avoid drying clothes indoors.
• Seal air leaks: Close windows and doors; seal obvious gaps that allow humid outdoor air in.
• Verify humidity sensor: Compare displayed humidity to a separate hygrometer. If the unit reads much lower than actual, the sensor may be faulty and should be replaced.
• Consider additional units: In very damp or large spaces, using two dehumidifiers may be necessary.

Note: In extremely humid conditions, continuous operation can be normal until the environment stabilizes.
