REPLACING FAN MOTORS AND BLADES
See cross section for location of evaporator
fans. Should it ever be necessary to service or
replace the fan motors or blades be certain that
the fan blades are re-installed correctly.
For access to RL / RM / RLN / RMN / RLNI /
RLNIE fans:
1. Turn off power.
2. Remove bottom display pans.
3. Disconnect fan from wiring harness.
4. Remove fan blade.
5. Remove screws holding fan motor/bracket
assembly to plenum and remove assembly.
6. Replace fan motor/bracket assembly and
reinstall screws.
7. Reinstall fan blade.
8. Reconnect fan to wiring harness.
9. Turn on power.
10. Verify that motor is working and blade is
turning in the correct direction.
11. Close air gaps under fan plenum. Warmer air
moving into refrigerated air reduces effective
cooling. If the plenum does not rest against
the case bottom without gaps, apply foam
tape to the bottom of the fan plenum to
reduce improper air movement. Use silicone
sealant to close other gaps.
12. Replace display pans. Bring merchandiser to
operating temperature before restocking.
