9. TROUBLESHOOTING (CONT’D)
PROBLEMS POSSIBLE CAUSES YOU SHOULD TRY THIS
7. The motor does not work. • The circuit board may be defective.
• The motor may be defective.
• The motor capacitor may be defective.
• The motor is unplugged from inside
the unit.
• The motor is unplugged from the
electronic board (J4).
• There is a problem with the door
magnet switch.
• JU-1 jumper is missing or in wrong
position.
• Press on the integrated control push button until the unit turns on low speed
(the LED will light AMBER). Using a multimeter, check the voltage on J9-4 and
J9-3. Refer to Section 6 Wiring Diagram. The reading must be 120 VAC Then
set the unit on high speed by pressing on the integrated control push button one
more time (the LED will light GREEN). Using a multimeter, check the voltage
on J9-4 and J9-2. The reading must be 120 VAC Check also between J4-2
and J4-1, the reading must be 120 VAC Refer to Section 6 Wiring Diagram. If
all the readings correspond to the right voltage values, the circuit board is not
defective. If one or both readings are different, change the circuit board.
• Using a multimeter, check for 120 VAC for the following speeds: High Speed:
between GREY and ORANGE wires; Low/Medium Speed: between GREY
and RED/BLUE wires. Refer to Section 6 Wiring Diagram.
• Unplug the unit. Check for continuity between Pin 5 on the 6-pin connector
(brown leads) and Pin 3 of the capacitor connector. Also check for continuity
between Pin 4 on the 6-pin connector (brown leads) and Pin 1 of the capacitor
connector. Refer to Section 6 Wiring Diagram.
• Open the door and ensure that the wire going to the motor is connected.
• Check J4 motor connection on circuit board.
• Door magnet switch is missing or not in its place (see item no. 11 on page 18).
•
Ensure JU-1 jumper is set on “M” speed (refer to Section 6 Wiring Diagram).
8. The defrost cycle does
not work (the fresh air
duct is frozen OR the
fresh air distributed is
very cold).
• Ice deposits may be hindering the
damper operation.
• The damper rod or the port damper
itself may be broken.
• The damper actuator or circuit board
may be defective.
• Remove the ice.
• Inspect these parts and replace if necessary.
• See point 4.
9. The integrated control
push button does not
work.
• The 30-second boot sequence is not
completed.
• The circuit board may be defective.
• The transformer may be defective.
• See Section 4.1.1 Boot Sequence (page 13).
• Check voltage going to circuit board J8-1 and J8-2.
• Check for 24 VAC on J8-1 and J8-2.
