Our dehumidifier turns on for only a few seconds, then shuts off.

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.

Good Morning Friend,

I understand that the compressor on your Frigidaire dehumidifier, model# FAD504TDD, comes on for a second and then shuts off. First, make sure that when you are first turning your dehumidifier on that you put it in continuous mode. After about 3 days of continuous mode, set your appliance to the humidity level you would like. Secondly, the "Compressor" circuit has an automatic 3 minute time delayed start if the unit is turned off and on quickly. This prevents overheating of the compressor and possible circuit breaker tripping. Thirdly, make sure the tank is fitted correctly otherwise your dehumidifier will not turn on. Lastly, make sure your dehumidifier has sufficient clearance to operate. There should be a minimum of 12 inches clearance around your dehumidifier. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your dehumidifier status has changed successfully. Hope this is helpful.

Here is a tip that I wrote that will help you understand why and what you cando with a dehumidifier that ices up.

Possibly., the unit turning ON vibrates the bucket in such a way, that it loses contact with the safety switch and the unit shuts OFF. If the dehumidifier is not sitting level, it would cause the bucket to shake more than usual. In addition, if you haven't cleaned the filter recently, I would suggest that you do that. A dirty or clogged filter causes the unit to struggle and if it is to much to handle, it will cause it to shut OFF. Before you attempt remove the filter, turn OFF the Master ON/OFF Switch and Unplug the unit. Be sure you do it in the order I listed.

Hope this helps you further to troubleshoot and solve the problem.

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.
