      If your Gree Air Conditioner won't start, first, confirm if there's a power failure and wait for the power to return. If not, check the power supply circuit and ensure the power plug is securely connected. Also, make sure the air conditioner is grounded reliably and the wiring is correct. Inspect the power cord for damage and replace it if needed. If the remote controller is not working, replace the batteries or repair/replace the remote controller. Ensure that you have the proper air switch selected.
