    sounds like it is running in heat mode when it should be in cooling mode. what is the system pressure on low side @ ambient temp?

Ok, on these units, if by high side line you mean the small tube going from outside to inside, that tube is actually on the low side, the metering device is in the outdoor unit. If you shut the unit down, let everything thaw then restart and find that small tube is freezing up right at the outdoor unit right away, my guess is its low on charge. I see that you put some in, make sure it is the right knid of refrigerant. they do not hold alot. Where is your suction pressure running. If you put 2 to 3 pounds with no change, you may have overcharged but that is telling you that there is a restriction in the line inside the outdoor unit, probably the filter if it has one, or the metering device itself. Let me know what you find.

    sorry, forgot to mention, since you are icing up, that says for sure (whatever reason) you are short on refrigerant on the low side, not enough to cool compressor, hence thermal trips.

WHAT IS PSI SUCTION PRESSURE IN SPLIT AC WHEN UNIT IS IN OFF CONDITION


there is no suction at all when the machine is off as the gas equalizes around the system
all you will read is the pressure of the gas in the system and that will tell you nothing
to read gas pressures you need to know the type of gas in the system , have gauges that can handle the high pressures and have two on a manifold so that you can read suction and high side pressure differences
That way you can see if the system is low on gas or over charged

Why does my split ac unit leak inside the house?


This happens when the drain pipe is too high, or kinked. The pipe must be lower then the drain pan in order for the water to drain. This is a common problem.

I have a sanyo split system and one of the inside units creates ice around the coils. the filters are clean and there's nothing blocking the air around it. What can it be?


There are reasons for.
1. Dusty indoor coil and blower wheel - Clean it.
2. Less speed of blower motor- Replace capacitor/motor
3. Short of gas- Find leak and rectify.

Thanks.

Indoor unit temperature between 60F & 70F after R22 charge..


The pressure changes with temperature, it is not a true gauge to ensure a proper charge.

You should have a 15 to 20 degree temp drop across the evap coil. (return air vs supply air)

Can you verify that the compressor is running?
Not the condenser, but the compressor located inside the condenser (outdoor unit)

it really sounds like it is still undercharged.
Check the temp drop, let me know what it is.
Also tell me what the outdoor ambient temp is.

( for example.... 98 degree outdoors with 85 degree indoor temp could result in pressures something like 325 on the high side and 75 or 80 on the low side.
With the exact same unit, but 80 degree outdoor temp combined with 70 degree indoor temp, your pressures could read 215 low side and 55 low side. Not to mention that more efficient units often have higher pressures on the low side because they have more coil space and remove heat more efficiently)

Cannot set a/c to operate automatically


sound to be in heat modenow. If you are after the cool mode, then if you have a cool setting and a heat temp setting, Lower the heat to almost off and set the cool setting to 74 degrees. See if the outside coils get warm. Make sure you are off manualo and n auto. If it runs, give it some time and the tenp of the outside coil will rise and the inside will get cold. Food Luck

2 ton sanyo suction pressure erratic


Your suction pressure is erratic, your max. pressure is to much high. You did not measure your unit current reading liquid line press. to complete the data. But the problem of your unit is not the compressor its the system. Try to reprocess the system flush the unit with nitrogen, isolate the capillary tube and flush it with nitrogen to insure that no restriction.
