Monitor Compressor Run Duration, Displays If Service, or Condenser Cleaning Is Needed
The microprocessor senses the 115 volt output supplied to both compressors, monitoring the length of compressor
run time (See Figure 3-18).
If several excessive compressor run periods occur, the microprocessor closes the condenser fan relay on the control
board, allowing the condenser fan to run 100%. A signal is then sent to the VACUUM CONDENSER indicator on
the LCD to flash (See Figure 3-19).
NOTE: Please keep in mind that a flashing VACUUM CONDENSER indicator is caused by excessive compressor
run, which could be related to problems other than a dirty condenser. This will be covered in the
TROUBLESHOOTING GUIDE.
NOTE: After correcting the cause of the error, the unit must be switched OFF, and back ON to clear the error indica-
tor.
