Possible Causes

Door left ajar or frequently opened, Damaged or deformed door gasket, Blocked condensate drain channel, Faulty humidity or temperature sensor calibration

How to Fix / Troubleshooting

Safety: No internal electrical work is usually required for this fault, but always unplug the unit if removing interior panels.

Steps to address H1:

  • Check door closure: Ensure the door closes fully and the hinges are not sagging. Adjust leveling feet so the cabinet leans slightly back, helping the door close firmly.
  • Inspect the gasket: Run a thin strip of paper around the door seal; if it pulls out easily in spots when the door is closed, the gasket may be leaking. Warm the gasket gently with a hair dryer and reshape it, or replace it if torn or hardened.
  • Clear the drain channel: Locate the small drain hole at the rear of the interior (if equipped). Use a soft pipe cleaner or cotton swab to clear any blockage so condensate can drain properly.
  • Reduce door openings: Minimize how often and how long the door is opened, especially in humid environments.
  • Sensor check: If the humidity alarm persists despite good sealing and drainage, the internal sensor (often combined with the temperature sensor) may be out of calibration and require replacement by a technician.

Tip: Avoid placing wet bottles or containers inside; wipe them dry first to reduce internal humidity.
