MAINTENANCE & REPAIR — PRE-SERVICE CHECK LIST
MAINTENANCE & REPAIR
29
You may avoid the cost and inconvenience of an
unnecessary service call by first reviewing this check
list of the most frequently encountered situations that
are not the result of system component failure.
COMPRESSOR RUNS TOO MUCH
1. A refrigerated cabinet automatically compensates for
service loading by running longer and more often.
Before calling for service, check running time for at
least one hour the first thing in the morning (before
store traffic starts).
2. Be sure doors seal. A faulty gasket seal will cause
increased running time.
3. Check the room temperature. The warmer the room,
the more the compressor will run.
4. Check to see that condenser fans are running.
5. Be sure the condenser fan operates.
6. Check to see that condenser fans are running.
7. If product is too hard, (cold) try setting the temperature
control (thermostat) warmer. This will result in warmer
cabinet temperature and reduced running time.
CABINET DOES NOT OPERATE
1. Be sure the cabinet is plugged in.
2. Check that the breakers or fuses are good and all
switches in the supply line are ON.
3. Be sure that cabinet Master Supply Switch is ON.
4. If you are in an area with voltage problems, try
shutting off all non-essential electric equipment.
LIGHT IS OFF
1. If the cabinet is operating, be sure the lamp is
properly seated in sockets.
2. If the cabinet is not running, check that Master Supply
Switch of cabinet is ON, fuses are okay, no switch in
the supply is off and the cabinet is plugged in.
CUSTOMER COMPLAINT
OR STORED PRODUCT
1. Check cleaning solutions used inside cabinet.
2. Check cleaning solutions, paint or other
contaminants used in store maintenance.
3. Sometimes the ingredients used in some products or
containers will contaminate other products.
4. Be sure to follow a weekly schedule for cleaning
cabinet interior.
SERVICE
In the event of a malfunction, damage to the cabinet, or
if the cabinet requires service beyond the items in the
“Pre-Service Check List,”
contact your local
refrigeration service company or the dealer or
distributor you purchased the unit from.
POWER FAILURE
Do not open the cabinet doors unnecessarily if power is
cut off due to electrical failure. The cabinet will start up
if the power supply returns, but will require sufficient
time to reach maximum cold storage performance.
CABINET FAILURE
1. If the cabinet has stopped operating, check that the
cabinet is securely plugged in and turned on. Contact
a licensed electrician to locate and correct any power
supply problems.
2. Do not open the cabinet lids unnecessarily.
3. Provisions for other storage of the product may be
required to prevent spoilage.
