Clicking sound every few minutes, compressor attempts to start but shuts off immediately.

Safety Warning

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Weak compressor, Failing start relay or PTC, Low supply voltage, Seized compressor rotor

How to Fix / Troubleshooting

Unplug the cooler before accessing the compressor.

Check supply voltage: Avoid extension cords; plug directly into a dedicated outlet.
Inspect start relay and overload: Remove the compressor terminal cover and check for burnt or cracked components. Replace with a Hisense-compatible start kit.
Allow cooling: If the compressor is very hot, let it cool for 30–60 minutes before retrying.

If the compressor continues to click and fail to start with new start components, the compressor itself may be locked and will require professional replacement.
