Hi All. Need some help. I have a Daikin unit model RUR15NY1 (outdoor unit) and FDR15NY1 (indoor unit) using R410A. I am having icing issues. My steps so far:-
1) after finding the evaporator coil fully iced, i turned off the system for a day.
2) turned on the unit on day 2 and checked. No more icing at evaporator but suction pipe and accumlator at condenser side is totally iced. set temperature able to achieve. Checked low side pressure is 90psi and high side is 380psi. I did not charge anymore gas because the suction pipe and accumulator are already icing.
3) The running amp is at 27A, very close to the max rated which is 26.4A. Therefore not adviseable to charge further gas.
So now i need the HVAC gurus to tell me what i should do next. BTW i am from Asia where the average ambient temperature is from 25 celcius to 35 celcius with humidity around 80 to 90RH.
