3. TRIAC
The triac controls the four hood lamps and is mounted in a box in the chimney area. Triac has an isolated
case, which is mounted to the chimney with two screws.
Note: Triac wire connection must be correct or lamp flickering could occur. Triac can be checked for electri-
cal short by removing the black lead and measuring the resistance between the two 1/4" terminals (termi-
nals with black and brown wires). Resistance should be greater than 1M ohm.
4. FUSE HOLDER
The fuse holder is an in-line type, which is in series with 12V AC from the transformer and is located in the
blackbox. An open fuse may be caused by a lamp failing or a wrong wattage lamp.
Note: The fuse is 5 x 20 mm and rated at (8) A, 250V AC (GE part number WB02X10584).
5. MOTOR CAPACITOR
The start/run capacitor is mounted in the black box and plugs into the Control PCB connector CN3.
6. TRANSFORMER
The transformer provides 12V AC to the hood lamps and the Control PCB power supply. It is attached by
four screws from the top of the chassis. The transformer is located next to the black box in Model ZV750
and above the grease filter in Model ZV850.
7. HALOGEN LAMPS
The 4 halogen lamps are the push-in type and rated at 12V AC/20W. The equivalent GE lamp is a
Q20MR16/C/CG40 - BAB.
8. FILTER MICROSWITCH
The microswitch is mounted in the filter area. When filters are removed, the microswitch causes the red
display light to blink continously. The red display light will also turn “on” after 30 hours of fan operation to
remind the user to clean the filters. Make sure the filter is seated properly when installed, or the filter light
will blink. NOTE: If electrical power is lost, the timer automatically resets to 0.
9. INDUCTION FAN MOTOR ASSEMBLY
The motor is a 4-speed, start/run capacitor, induction type rated at 120V AC/1.7A. Motor stator winding
resistances:
Orange-Red = 17 ohms Blue-White = 8.5 ohms
Blue-Black = 17 ohms Black-White = 8.5 ohms
