To access the condenser fan assembly, slide the unit
tray out half way and disconnect the compressor, con-
denser fan, solenoid and ground wire electrical leads.
Then continue sliding the tray out while pivoting it to
the right.
NOTE: Move tray slowly and observe the sealed sys-
tem tubing. Care must be taken to avoid kinking any of
the tubing.
