Cleaning the Condenser

GENERAL

A dirty condenser restricts airflow, resulting in
excessively high operating temperatures. This reduces
ice production and shortens component life. Clean the
condenser at least every six months. Follow the steps
below.

1. Clean the outside of the condenser with a soft brush

or a vacuum with a brush attachment. Be careful not
to bend the condenser fins.

2. Shine a flashlight through the condenser to check

for dirt between the fins. If dirt remains:

A. Blow compressed air through the condenser fins

from the inside. Be careful not to bend the fan
blades.

B. Use a commercial condenser coil cleaner.

Follow the directions and cautions supplied with
the cleaner.

3. Straighten any bent condenser fins with a fin comb.

Straighten Bent Condenser Fins

4. Carefully wipe off the fan blades and motor with a

soft cloth. Do not bend the fan blades. If the fan
blades are excessively dirty, wash with warm, soapy
water and rinse thoroughly.

!

Warning

Disconnect electric power to the ice machine head
section and the remote condensing unit at the
electric service switches before cleaning the
condenser.

!

Warning

The condenser fins are sharp. Use care when
cleaning them.

!

Caution

If you are cleaning the condenser fan blades with
water, cover the fan motor to prevent water
damage.
