Splitvolt EV charger makes loud clicking, buzzing, or humming noises during operation.

Safety first: Unusual noises can indicate arcing or failing components. Turn off power if you suspect arcing.

• Identify noise source: Listen carefully to determine if the sound is a single click at start (normal) or continuous clicking/buzzing (abnormal).
• Check mounting: Ensure the Splitvolt charger is firmly mounted to a solid surface. Tighten mounting screws if loose.
• Observe operation: If the charger repeatedly starts and stops with each click, discontinue use and turn off power.
• Professional inspection: Chattering relays or buzzing transformers indicate internal faults that require technician diagnosis and possible relay or board replacement.
