Power Supply Board

Transformer

The transformer supplies 12 VAC to the  power 
control board (PCB) and the lighting circuit. It is held 
in place by two Phillips-head machine screws and   
7 mm hex nuts.

Transformer Resistance:

Primary winding (black to white wires) - 7 

Ω. 

Secondary winding (blue to brown wires) - 0.3 

Ω.

Check for 120 VAC between the white and black 
wires. Check for 12 VAC between the blue and 
brown wires. 

Triac 

The triac controls the two hood lights. It is located 
inside the upper component box. It is held in place 
by 2 Phillips-head machine screws and 7 mm hex-
nuts.

If the hood lamps fl icker, the triac wire connections 
are incorrect. The triac can be checked for an 
electrical short by removing the black lead wire and 
measuring the resistance between the two ¼-in. 
terminals (black and brown wires). Resistance should 
be greater than 1M 

Ω

.

PTC Board

The PTC board provides protection for the lighting 
circuit during momentary power surges. It is located 
inside the upper component box.

Motor Capacitor

The motor capacitor has a value of 25 

µ

fd. It is 

located inside the upper component box.

Power Supply Housing

WARNING:

 Components in the power supply 

housing are electrically 

HOT

 when voltage is 

connected to the hood.

The power supply housing is located above the fan 
housing behind the duct cover. To access the power 
supply housing, remove the duct cover, (see 

Duct 

Cover

) then remove the 2 Phillips-head screws that 

hold the power supply cover in place. 

Power Supply Housing Cover

Screw

The transformer is located in the power supply 
housing. The triac, fuse holder, motor capacitor, and 
power supply board are located in the power supply 
housing in separate upper and lower component 
boxes.
