Dehumidifier Not Working? 5 causes and how to fix it

Failed compressor capacitor. The capacitor helps the compressor run. When you find that your dehumidifier is running and both exhaust/intake fans are running, it''s a good sign that the capacitor for the compressor is bad. You may also notice that water is not being collected from the air, or the overload device keeps tripping.
