5.4 Cleaning the
Refrigerator
The refrigerator’s exterior may be periodically cleaned with
soapy water using a sponge or nonmetallic brush to keep it free
from corrosive solutions, grease, oil, etc. After cleaning, it should
be wiped dry. Automotive wax may be applied to the interior and
exterior surfaces of the refrigerator to make them easier to clean
and more resistant to corrosion. Do not direct a hose spray
toward the underside or into the front grille of the refrigerator.
The vacuum formed plastic refrigerator interior may also be
cleaned with soapy water as necessary.
Because the refrigerator uses a forced-air system for cooling the
compressor and condenser coil; dust, lint, and other debris will be
pulled into the unit and will eventually accumulate on the con-
denser coil and other components in the air circulation path. If
the refrigerator is not cleaned periodically, damage due to over-
heated components may result.
WARNING
Disconnect the refrigerator’s power before performing any
service activities
The condenser coil and surrounding areas should be cleaned
annually; more frequently under severe operating conditions. To
clean,
1. Remove the screws that hold the back panel on to the
refrigerator and remove the panel.
2. Vacuum the fan, compressor, and surrounding areas.
3. Check the fan for freedom of movement. Oiling the fan
motor is not necessary because the motor bearings are
sealed. If the fan motor does not rotate freely, it should be
replaced.
4. Replace the back panel.
5. Remove the front grille. Vacuum the condenser coil and
surrounding areas.
6. Replace the grille.
