SERVICE HANDBOOK
• Prolonged operation on start cycle due to starting load too high. Refer to the OEM
service information to use pump down arrangement, if necessary.
• Excessive short cycling. Short cycling can be caused by problems with the com-
pressor's thermal protector or system components such as the thermostat, control,
contactor, or high or low pressure cut-out. For more information on troubleshooting
the system components, refer to the OEM service information.
Step 6: Replace Current Relay
If all above tests prove satisfactory, there is no capillary restriction, and the unit still fails to
operate properly, replace the relay. The new relay will eliminate any electrical problems
which cannot be determined with above tests.
Step 7: Continue Troubleshooting
If the new relay does not correct the problem, check for adequate compressor pumping as
outlined in the procedure on page 70.
