Hello, the clicking will be coming from a relay.
Can you locate any relays and check those first?
Please confirm the part number of the board if you need further assistance troubleshooting it.
You should see two black relays, circled in red on the following diagram - start by checking the solder joints on these.
I would check the solder joints first.
If touching up the solder joints doesn't help then the correct voltage may not be supplied into the relay - checking voltages will be the next step.
If the voltages are good then the relay is suspect.
