ACTUATOR REMOVE AND REPLACE PROCEDURES
Removing the actuator assembly when the actuator has failed in the open position:
Stack wooden blocks/boards under the hood (where the actuator is connected to the hood), to keep the hood open when
the actuator is removed. Be careful to make the stack of wood stable.
Remove the bonnet bridge sheet metal piece on the end of the oven where the actuator will be changed.
Remove the two safety clips from the pin holding the actuator piston to the bracket. Remove the piston pin holding the
actuator piston to the bracket. You may need to exert some pressure on the inner hood assembly to remove the pin.
The body of the actuator is accessed through the equipment cabinets on each end of the oven.
Unplug the actuator from the control box and remove the actuator
cable with the actuator.
