Haha cooler will not power on

Power problems usually trace back to outlet load, power supply issues, or a loose connection at the cooler.

• Confirm the outlet is live with a known-good device.
• Inspect the power cable for pin damage or cuts.
• Verify the power switch and internal breaker (if applicable).
• Check for LED activity on the controller after power is applied.

• Move the unit to a different outlet and retest.
• Reseat the power cable at the unit and wall outlet.
• If the unit boots briefly then shuts off, check for overheating or low voltage.

• Avoid daisy-chaining multiple devices on one outlet.
• Use a surge protector rated for commercial loads.
• Keep vents clear to prevent thermal shutdown.

• No LED activity after verified power input.
• Repeated shutdowns after 1–2 minutes of operation.
• Visible damage to the power cord or connector.
