Run range hood and check all the functions.

Check start capacitor

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

meter to each end of one wire. If the meter does not indicate zero resistance replace the

wire / harness part.
