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 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.

Always disconnect the electrical power 

at the main disconnect when servicing or 

replacing any electrical component. This 

includes, but is not limited to, such items 

as fans, heaters, thermostats and lights.

Hussmann recommends against frame heater 

cycling with 

Innovator

 doors to prevent door 

seals from freezing to the frames and tearing.
