MAINTENANCE & REPAIR — PRE-SERVICE CHECK LIST
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.

2. Check that the breakers or fuses are good and all
switches in the supply line are ON.
