CONCERN
POTENTIAL CAUSE
COMMON SOLUTION
SOUND AND NOISE
Louder sound levels
whenever keg cooler
is on.
• Modern keg coolers have in-
creased storage capacity and
more stable temperatures. They
require a high-efficiency
compres-
sor.
• This is normal. When the surrounding noise level is low, you
might hear the compressor running while it cools the interior.
Longer sound levels
when compressor
comes on.
• Keg cooler operates at high
pressure during the start of the
“ON” cycle.
• This is normal. Sound will level off or disappear as the keg
cooler continues to run.
Popping or cracking
sound when compres-
sor comes on.
• Metal parts undergo expansion
and contraction, as in hot water
pipes.
• This is normal. Sound will level off or disappear as the keg
cooler continues to run.
Bubbling or gurgling
sound like water boil -
ing.
• Refrigerant (used to cool keg
cooler) is circulating throughout
the system.
• This is normal.
Vibrating or rattling
noise.
• Keg cooler is touching the wall.
• Move keg cooler slightly away from the wall.
Snapping noise.
• Temperature control turning keg
cooler on and off.
• This is normal.
