Condenser Fan Assembly Removal (Model ICB424)
The condenser fan motor is secured to the condenser
bracket with screws. The bracket is secured to the unit
tray by screws passing up from under the unit tray into
threaded stand-offs.
To access the condenser fan assembly, the unit will
need to be pulled from its installation.
NOTE: If removing a model ICB424 from its installa-
tion, an anti-tip bracket and a countertop bracket may
have been used to make a solid installation.
After pulling unit from its installation
1. Remove access panel from bottom back of unit.
2. Disconnect fan motor electrical leads.
3. Extract grounding screw.
4. Lean unit toward front or side, and extract bracket
mounting screws, then lift assembly from unit tray.

1. Remove access panel from bottom back of unit and
door closer from bottom front corner.
2. Extract screws securing unit tray to cabinet on the
left side, and loosen screws on right side.
