COMPONENT TESTING
Before testing any of the components, perform
the following checks:
• The most common cause for control failure is
corrosion on connectors. Therefore, disconnecting and reconnecting wires will be necessary throughout test procedures.
• All tests/checks should be made with a VOM
or DVM having a sensitivity of 20,000 ohmsper-volt DC, or greater.
• Check all connections before replacing components, looking for broken or loose wires,
failed terminals, or wires not pressed into
connectors far enough.
• Voltage checks must be made with all connectors attached to the boards.
• Resistance checks must be made with power
cord unplugged from outlet, and with wiring
harness or connectors disconnected.
WARNING
ELECTRICAL SHOCK HAZARD
Disconnect power before servicing.
Replace all panels before operating.
Failure to do so could result in death or
electrical shock.
BLOWER MOTOR
BALLAST TRANSFORMER
(ISLAND HOODS ONLY)
Refer to page 2-2 (wall hoods), or 2-10 (island
hoods), for the procedure for accessing the
blower motor.
1. Disconnect the electrical power to the
hood.
2. Disconnect the wires from the blower motor
terminals.
3. Set the ohmmeter to the R x 1 scale.
4. Touch the ohmmeter leads to the blue and
white motor wires. The meter should indicate between 15 and 35 Ω.
Refer to page 2-7 (island hoods), for the procedure for accessing the ballast transformer.
1. Disconnect the electrical power to the
hood.
2. Set the ohmmeter to the R x 1 scale.
3. Touch the ohmmeter leads to the ballast
transformer wire ends at the wire nut and
the fluorescent lamp socket. The meter
should indicate between 18 and 28 Ω.

Refer to page 2-2 (wall hoods), or 2-8 (island

slide switches.
NOTE: The island hood slide switches are
soldered to the control board and have to be
tested on the board. The wall hood slide
switches have wire connectors that can be
removed for testing.
1. Disconnect the electrical power to the
hood.
2. Disconnect the wires from the switch terminals (wall hoods).
3. Set the ohmmeter to the R x 1 scale.
4. Refer to the illustration above, and touch
the ohmmeter test leads to the switch pins
that have the slider in the “contact” position (1). The meter should indicate a closed
(0 Ω) circuit.
5. With the meter leads at the same pin
locations and the slider in another position, the meter should indicate an open
(infinite) circuit.
NOTE: If the readings do not indicate as specified, replace the switch (wall hoods) or the
control board (island hoods).
Slider
Refer to page 2-8 (island hoods), for the procedure for accessing the control board.
NOTE: The island hood speed control is soldered to the control board and can be tested on
the board.
1. Disconnect the electrical power to the
hood.
2. Set the ohmmeter to the R x 10K scale.
3. Position the speed control slider all the
way to the left (see above).
4. Touch the ohmmeter test leads to the two
indicated terminal screws (with the orange
and blue wires). The meter should indicate approximately 260K Ω.
5. Leave the leads touching the two terminal
screws, and slowly push the slider all the
way to the right. The meter resistance
