It runs for a few seconds and then shuts off - Comfort-Aire HD-301 Dehumidifier

There are several reasons why your T2 Direct Dehum 3 dehumidifier may be alarming after running for a few seconds:

1. Dirty or Clogged Air Filter: A dirty or clogged air filter can cause the dehumidifier to overheat and shut down. Check the air filter and clean or replace it if necessary.
2. Defective Humidity Sensor: If the humidity sensor is defective, it may cause the dehumidifier to shut down. The sensor may need to be replaced.
3. Faulty Compressor: A faulty compressor can cause the dehumidifier to shut down after running for a short time. You may need to replace the compressor.
4. Low Refrigerant Charge: If the refrigerant charge is low, it can cause the dehumidifier to shut down. You may need to recharge the refrigerant.
5. Faulty Control Board: A faulty control board can cause the dehumidifier to shut down or display error messages. You may need to replace the control board.

It is recommended to contact a qualified technician to diagnose and repair the issue with your dehumidifier.

ck the water catch bucket , sometimes ive seen machines stop after running a few minutes because it shook catch bucket from its perch

Wendy, it's probably because the humidity level on the unit is set higher than the humidity level in the house. Keep in mind, the humidity level you set the control to, is not the amount extracted from the air. It's the level you want it to maintain. The higher the percentage level, the more humidity stays in the house. The lower the percentage level, the more humidity it removes, until the lower humidity level is reached. Then the humidifier will automatically shut OFF and/or the unit shuts OFF, because the bucket is full. Once it's emptied and replaced, if the unit needs to continue to extract humidity, it will start running again.

Hope this helped you solve the problem. Please let me know. Thanks.

Hi,

Here is a tip that explains what can be happening to make the dehumidifier show that the bucket is full when it is not.

Dehumidifier Problem It shows Bucket Full

run it without the filter with a 1 part vinegar 4 parts water. then try it with a clean or new filter. You may need to run it a few (5-6) times before it stops shutting off by its self.

If the water reservior is empty then the float is stuck in the full position.

no reason for the fan to run dehumidifier not air circulator. its reading the humidity and shutting off.buy a fan.

sounds like the compressor is seized.

The float switch for the condensate reservoir (bucket) is malfunctioning.

It's sending a false signal that the bucket is full.

Maybe just stuck and needs cleaning or it may have failed.
