6) HALOGEN LAMPS
The four halogen bulbs are the push-in type rated
at 120V, 25 watts, T4, clear, 9mm bi-pin.
TO CHANGE THE LAMPS
Use a small at-blade screwdriver to remove the
lamp lens cover.
TO REPLACE A HALOGEN LAMP ASSEMBLY
Reach inside the chassis and press with ngers
against the metal spring clips. Pull out the lamp
assembly and disconnect
the wire connector.
7) FILTER
MICROSWITCH
A microswitch is mounted
in the lter channel on the
right side. It senses when
lters are removed. The red
display light glows when:
1. The lter is removed
2. If the lter is not making
contact with the switch
3. After 30 hours of fan
operation to remind the
user to clean the lters.
Make sure the lter is
seated properly when installed and the lter light is not on.
TO REMOVE AND REPLACE FILTER MICROSWITCH
Remove 2 screws and lift out the switch. The harness is connected to
the PCB assembly. Refer to the schematic to locate and disconnect the
control CN7.
8) UTENSIL RODS
Remove lters for access to screws holding rods under chassis. Screws
(2) holding theutensil rods can now be removed from the inside.
9) REINSTALL DUCT COVERS
• Remove stop screw and place in envelope.
• Slide duct cover down.

IMPORTANT SAFETY NOTICE
THIS INFORMATION IS INTENDED FOR USE BY PERSONS
POSSESSING ADEQUATE BACKGROUNDS OF ELECTRICAL,
ELECTRONIC AND MECHANICAL EXPERIENCE. ANY ATTEMPT
TO REPAIR A MAJOR APPLIANCE MAY RESULT IN PERSONAL
INJURY AND PROPERTY DAMAGE. THE MANUFACTURER OR
SELLER CANNOT BE RESPONSIBLE FOR THE INTERPRETATION
OF THIS INFORMATION, NOR CAN IT ASSUME ANY LIABILITY IN
CONNECTION WITH ITS USE.
DISCONNECT POWER BEFORE SERVICING
IMPORTANT: RECONNECT ALL GROUNDING DEVICES.
ALL PARTS OF THIS APPLIANCE CAPABLE OF CONDUCTING
ELECTRICAL CURRENT ARE GROUNDED. IF IT IS NECESSARY TO
REMOVE GROUNDING WIRES, SCREWS, STRAPS, CLIPS, NUTS OR
WASHERS USED TO COMPLETE A PATH TO GROUND, THEY MUST BE
RETURNED TO THEIR ORIGINAL POSITION AND PROPERLY FASTENED.
GROUNDING SPECIFICATIONS
Ground Path Resistance 0.10 Ohms Max.
Insulation Resistance 250K Ohms Min.
INSTALLATION REQUIREMENTS:
Power Supply
The hood must be connected to a supply circuit of the proper voltage
and frequency as specied on the rating plate. Wire size must conform
to the National Electrical Code or the prevailing local code. The rating
plate is located on the left side and is visible when lter is removed.
WARNING: IMPROPER CONNECTION OF ALUMINUM
HOUSE WIRING TO COPPER LEADS CAN RESULT IN A SERIOUS
PROBLEM. USE ONLY CONNECTORS DESIGNED FOR JOINING COPPER
TO ALUMINUM AND FOLLOW THE MANUFACTURER’S RECOMMENDED
PROCEDURE CLOSELY.

Fan Keypad Operation
1 - ON/OFF – Remembers the last
fan speed used
2 - Decreases speed
3 - Increases speed
4 - Boost speed
5 - Delayed fan shuto – Choose
5, 10 or 20 minutes by pushing
this button (see item 10).
1) USER INTERFACE ASSEMBLY
The replacement assembly has a PCB mounted in a plastic enclosure with
(8) push buttons. It consists of the Fan Touch Control, Lamp Touch Control,
the Display PCB, and a ribbon cable with ferrite bead looped through the
other end near the control housing.
To access this assembly, remove 2 screws on the inside corners of the
front lter channel panel. Remove 2 access panel screws as shown.
Loosen (do not remove) 3 thumb screws until it does not interfere with
control box removal. Slide the display box out to the left side and
uncouple ribbon cable.
REMOVE FILTERS:
For access to lighting and wiring.
Grasp knob and push lter towards
the rear, tilt downwards and
remove.
TO ACCESS COMPONENTS:
1. Slide bottom duct cover up. Locate
service manual envelope with stop screw.
2. Install stop screw as shown in the bottom hole of the inner duct cover.
CAUTION: Components on the electronic control are
electrically HOT when voltage is connected to the hood.
Be sure to reconnect ribbon cable before reinstalling the control.
IMPORTANT: Before replacing the assembly, check the operation of the
hood by plugging the new User Interface Assembly into the existing
ribbon cable. If the unit does not work, replace the control board rst
and then recheck to determine if the existing User Interface Assembly is
functioning properly.
2) USER INTERFACE DISPLAY CRYSTAL - To access User
Interface Display crystal, follow step 1.
3) CONTROL PCB - This PCB has the AC to DC power supply,
microprocessor and fan relays and is located in the left box in the hood
chimney area.
NOTE: The 4 green connectors are locking type. Use a small at blade
screwdriver to unlock as follows: Insert screwdriver in the center of the
space between the plug and connector receptacle on the PCB. Push
down on the screwdriver and pull out the plug at the same time.
TO CHECK OPERATION OF CONTROL PCB: Check that all
connectors are locked in place, no leads are broken and connector
solder joints are not broken on PCB copper side.
4) MOTOR CAPACITORS - (2) 25uF 250V AC
The capacitors are mounted on right chimney and plug into the Control
PCB connector CN3. Check that the capacitors are not open or short by
using VOM.
5) INDUCTION FAN MOTOR ASSEMBLY - 2 person job
Motors are four speed capacitor run induction types, each rated at
120V AC/2.9A
1. Disconnect blower connectors, cut wire ties and pull cables through
slot to underside of chassis.
2. Remove ground connection nut, washer and wires.
3. While supporting blower assembly, remove (4) screws from under
chassis that retain blower asm (see illustration).
Note: Each blower cable has a connector. Each connector leads to a main
connector inside the left box. Make sure all connections are secure.
Replace lens cover. Make sure the tabs are inserted into the slots.
