TROUBLESHOOTING GUIDE PRO WALL HOOD
This section explains how to troubleshoot various components
in a Wolf Pro Wall Hood.
WARNING
To avoid electric shock, disconnect power to the
hood when preparing for tests. Care should be used
while doing any test with the hood energized.
WARNING

PRO WALL HOOD TROUBLESHOOTING TABLE
Symptom Possible Cause or Diagnostic Test Resolution
Hood lights and blower do
not turn on.
The breaker is open. Reset the breaker.
GFCI circuit is tripped. The unit should not be installed on a GFCI circuit.
Change the outlet type.
Verify the house circuit is dedicated, the correct
voltage, and sized correctly.
If necessary, contact an electrician to bring the circuit
into specification.
Confirm that the L1, N, and ground are correctly
connected. Make sure the connections are tight.
Blower motor runs only at
high speed.
Heat sensor closed. Confirm heat sensor is closed.
Blower speed control. Check for voltage changes out of the blower speed
control.
Hood lights do not work. Test the operation of the halogen lamp. If only one halogen lamp is out, replace the halogen
lamp.
Disconnect the wire connectors from the light switch
and measure the resistance.
If no continuity in either the on or off position, replace
the light switch.
Disconnect the electrical supply wire to the light
switch and check for the correct voltage.
If no voltage, trace the wire to the issue and repair the
wire.
Blower motor does not
run at any speed.
Internal blowers: Check the voltage at the blower plug
socket connector while the blower is running.
Check L1 to ground, L2 to ground, and L1 to L2 for
the correct voltage.
Disconnect the wire connectors from the blower
switch and measure the resistance.
If no continuity in either the on or off position, replace
the blower switch.
Disconnect the electrical supply wire to the blower
switch and check for the correct voltage.
If no voltage, trace the wire to the issue and repair the
wire.
Test the resistance of the blower speed control. The resistance of the blower speed control should
change as the knob is turned. The resistance should
never be infinite or open.
Check the blower. Replace the blower.
Blower motor runs, but
does not change speeds
(not at high speed).
This failure can be caused by:
▪Blower speed control failure
▪Wrong voltage supplied to the hood
1Check the voltage to the hood.
2Check the voltage output of the blower speed
control by back-pinning the wire connector of the
black to orange wire connector to ground. The
voltage should change as the knob is turned.
Blower comes on by itself. Heat sensor is closing. ▪Hood installation to close to cooking equipment.
▪Cooking equipment producing too much heat.
▪Blower issue.
▪Ducting issue.
▪Heat sensor failure.
Hood does not move
enough air.
Verify the duct run is the correct size, including:
▪Wall/roof cap is correct.
▪No reduction in size at any point.
▪Damper is installed correctly.
▪No excessive elbows.
▪No excessive length.
▪No air box used.
Correct the duct issue. Recommended duct size is
10".
Blower motor is not changing speeds. See "Blower motor runs only at high speed" or
"Blower motor runs, but does not change speeds."
Filters are dirty. Remove the filters to test. Clean the filters.

TEST THE LINE VOLTAGE IN THE WIRING BOX
WARNING
Components are energized during these tests.
Use extreme caution to prevent electrical shock
or shorting out the unit.
1Disconnect the wire connectors from the home power
supply.
2Measure the voltage from the electrical supply L1 (typically
black) to ground. The voltage should be 110 VAC to 127
VAC.
3Measure the voltage from the electrical supply neutral
(typically white) to ground. The voltage should be 0 VAC.
4Measure the resistance from the electrical supply ground
(typically green) to ground. The resistance should be 0 Ω.
5Measure the voltage from the electrical supply L1 to neutral.
The voltage should be 110 VAC to 127 VAC.
TEST THE LINE VOLTAGE AT THE BLOWER PLUG SOCKET
WARNING
Components are energized during these tests.
Use extreme caution to prevent electrical shock
or shorting out the unit.
1On the blower plug socket side of the wire connector, back-
pin the black and white wires as described below, with the
blower running on high.
2Measure the voltage from the black wire to the ground. The
voltage should be 110 VAC to 127 VAC.
3Measure the voltage from the white wire to the ground. The
voltage should be 0 VAC.
4Measure the resistance between the ground to a unit
ground. The resistance should be 0 Ω.
5Measure the voltage from the black wire to the white wire.
The voltage should be 110 VAC to 127 VAC.
TEST THE INTERNAL BLOWER
Do these tests only after confirming the voltage is correct up to
the internal blower.
1Unplug the internal blower plug.
2On the blower plug, measure the resistance from pin L1 to
Neutral.
3Measure the resistance from the plug L1 to the blower
casing.
4Measure the resistance from the plug Neutral to the blower
casing.
5If the reading is open from L1 to Neutral or there is
continuity from L1 or Neutral to the blower case, replace the
blower.
