No Power / Dead Unit
Symptom
Dehumidifier emits a burning smell or visible smoke.
Electrical Overheating / Component Burnout
Symptom
Dehumidifier fan does not run; compressor may start and then shut down quickly.
Fan Motor Failure
Symptom
Dehumidifier freezes up; evaporator coil becomes covered in ice during operation.
Evaporator Coil Icing
Symptom
Dehumidifier leaks water onto the floor instead of into the tank or drain hose.
Water Leakage / Drainage Fault
Symptom
Dehumidifier makes loud rattling or buzzing noises during operation.
Excessive Noise / Vibration
Symptom
Dehumidifier runs but collects very little or no water even in humid conditions.
Poor Dehumidification / Low Capacity
Symptom
Dehumidifier runs continuously and never reaches the set humidity level.
Inadequate Dehumidification / Oversized Space
Symptom
Dehumidifier runs for a few minutes then shuts off, even though the room is still humid and the tank is not full.
Short Cycling / Premature Shutdown
Symptom
Display is blank or very dim, but the unit may still run when plugged in.
Display Failure
Symptom
Musty or moldy odor coming from the dehumidifier during operation.
Odor / Biological Growth in Drain System
Symptom
Unit powers on but compressor never starts; fan runs continuously and no water is collected.
Compressor Not Starting
Symptom
Unit shuts off and will not restart for several minutes even when humidity is high.
Compressor Short-Cycle Protection / Thermal Delay
Symptom
Unit trips the household circuit breaker or GFCI when turned on.
Electrical Short or Ground Fault
Symptom
Unit vibrates excessively and may move on the floor during operation.
Severe Vibration
Symptom
