Internal compressor noise.
Loose set screws
Worn bearings of Motor Assembly
The bucket is not installed properly.
Connection may be loose.
Leak in bucket
Water drips when bucket removed for
emptying.
Bucket overflows.
High or low line voltage. (115V ± 10%)
Poor air circulation.
Heat Exchange clogged with dust or dirt.

REMEDY
If cracked, out of balance, or partially
missing, replace it
Remove it.
Adjust tubing routine carefully.
Check Motor Mount. If loose, tighten it.

Check micro switch and float.
Check line voltage. It must be between
103.5V and 126.5V volts.
If intermittent, provide new supply.
Move dehumidifier for free and
unobstructed air flow.
Clean dust or dirt on the Heat Exchange.
If not running, determine the cause.
Replace if required.
Check electrical circuit. Repair.
Allow 2 or 3 minutes for pressure to
equalize before starting compressor.
Test the capacitor.
Check the terminals. If loose, repair or
replace.
Check the system for a restriction.
Check compressor, replace compressor
Check OLP, if externally mounted.
Replace if open. (If the compressor
temperature is high, remove the OLP,
cool, and retest.)
