Check Procedure - Electrolux FHWC3050RS Servicing

Check procedure

Code
Check PCB control board
A
1. Disconnect the power and remove the PCB control board.
2. Check for any discoloration or broken parts, if any, replace the PCB control board.
3. Reconnect all leads removed during testing
4. Reconnect the power supply.
5. Run range hood and check all the functions.
Check start capacitor
B
1. Disconnect the power, open the electrical cover control, disconnect and remove the motor
start capacitor.
2. Check with a high ohm scale if the motor start capacitor is short or open between the
terminals with digital multimeter. If the capacitor is normal, the meter will show continuity for
a short time and then should indicate an open circuit once the capacitor is charged. If the
above is not the case, replace the capacitor. Also replace the motor start capacitor if the
wires are cracked or the capacitor looks deformed.
3. Reconnect all leads removed during testing
4. Reconnect the power supply.
5. Run range hood and check all the functions.
Check wires & harnesses to PCB control board
C
1. Disconnect the power, open the electrical cover control.
2. Check if the wires are discolored, cracked, broken, short circuit.
3. Check wires are seated in connector housing and fit correctly with mating connector.
4. Use the digital multimeter to test the resistance of the connector pins. Connect a lead of the
meter to each end of one wire. If the meter does not indicate zero resistance replace the
wire / harness part.
5. Reconnect all leads removed during testing
6. Reconnect the power supply.
7. Run range hood and check all the functions.
