To Next PageTo Next PageWhy is my Daikin RYMQ12T7Y1B discharge temperature too high?
The discharge temperature may be too high due to a closed stop valve or a refrigerant shortage. To resolve this, open the stop valves and check the refrigerant amount, recharging the unit if necessary.
What to do if my Daikin Air Conditioner has low pressure malfunction?
If your Daikin Air Conditioner is showing a low pressure malfunction, the stop valve might be closed, there could be a refrigerant shortage, or there might be an indoor unit malfunction. You should open the stop valves, check the refrigerant level and recharge if needed. Also, verify the user interface display and the transmission wiring between the outdoor and indoor units.
Why is my Daikin Air Conditioner compressor casing temperature too high?
A high compressor casing temperature could be due to a closed stop valve or a refrigerant shortage. The suggested solution is to open the stop valves and check the refrigerant amount, recharging the unit if necessary.
What causes Daikin RYMQ12T7Y1B high pressure switch activation?
The high pressure switch in your Daikin Air Conditioner might be activating because of a stop valve issue or abnormalities in the field piping, or airflow over the air cooled coil.
What to do if my Daikin RYMQ12T7Y1B indicates unusual low pressure on suction line?
If your Daikin Air Conditioner shows unusual low pressure on the suction line, immediately close valve A and push BS1 to reset. Before retrying the auto charge procedure, verify that the gas side stop valve and the refrigerant cylinder valve are opened correctly, and that the air inlet and outlet of the indoor unit are not obstructed.
