Convection Blower Removal 

 

 

Make sure the stove has fully cooled (approximately 25 minutes) before conducting service. Unplug the 
stove to prevent electrical shock. 
 
 

 

The removal steps are the same for both blowers however there are additional steps to gain access to 
the blower on the left hand side of the stove.  If you are only removing the right hand blower, see the 
instructions for removal of the Power Control Board (PCB). 

 

 

The (2) blowers have different orientations and different part numbers.  Make sure you are ordering the 
correct part.  

The fans are named “Left” or “Right” based on facing the front of the stove.

 

 

1.  Remove the side panel (see section “Side Panel Removal). 

 

2.  Disconnect the wiring (orientation of the wires does not matter when re-connecting) 

 

 

 

3.  Remove the (3) 3/8” screws that mount the blower and shroud to the stove body (set aside for reinstallation).  The side (2) 

can be removed with a nut driver; the top (1) will require a small ratchet or a box wrench.
