If you are having issues with your Gree product or if you encounter errors while using your home appliances, then you might encounter error code u1 on your device’s screen.
To fix this error, you need to try a few solutions.
- Replace the compressor
- Check any faulty wirings
- Replace the control board
Option 1: Replace the compressor
If your Gree device is running fine and you cannot get the error code u1, then you can try replacing the compressor. This is a common solution for all appliance errors and it will solve your problem without having to purchase a new appliance.
Make sure that you clean it properly so that there are no issues with its performance later on when you replace it with a new one. You can also use some silicone grease to make sure that there are no problems with its performance as well.
Install a new compressor and connect it to your appliance. Also, connect the cable connector to your appliance’s power supply.
Option 2: Check any faulty wirings
If you cannot fix your Gree device using Option 1, then you can try using Option 2. This is another solution that will help you fix this error without having to purchase a new appliance.
The wiring in these devices can be very complex, so you must use a multimeter or electrical tester that is compatible with the wiring system of these devices so that you can easily identify any issues with your wiring connections.
Option 3: Replace the control board
If you cannot fix your Gree device using Option 1 or Option 2, then you can try replacing the control board. This is another solution that will help you fix this error without having to purchase a new appliance from Gree.
Disconnect your device from its power supply and check for any faults in its components. You can do this by using a multimeter or an electrical tester that is connected to an electrical outlet and using it on your device’s wires and the outlets themselves.
