I would start wiyh a thourogh cleaning of the coils and blower.If you have service ports check to make sure you have the proper amount of refridgerant. If you do not have service oorts you can put some on that just clamp over the pipes and are self tapping. Hope this helps you. Thanks.

How can resolved PJ error in daikin vrv 2


PJ is an error that has to do with the outdoor unit not matching the indoor unit. This means the outdoor board thinks it's a 2 ton unit and the indoor thinks it's a 1 ton unit. (Just throwing those numbers in)...but, the indoor is not matching the outdoor. You need to read the manual and go through the setup process.

My window AC of 1.0 ton capacity is drawing 8.4 amperes instead of 7.0 (max,).There is no abnormal sound from any where in the AC ,Voltage is full(230-VOLTS). is this may be the case of low cmpressor oil...


Is the AC cooling properly?
If it is I would not bother it.
Your amp draw while somewhat high is not significantly high and would not worry me from a trouble-shooting angle, especially if it's cooling well.
Did you read the amp draw with the cover off the AC? If you did that would account for a slightly high reading. Even if you read it with the cover on - I would not worry about it, as I said above, it's just not that significant.
As far as 'low oil level.' -- I would not even be thinking about "oil" or whether or not it was low or whatever. This is just not an issue in such a small unit.

Check for communication from indoor to out door.Check power in out door unit. If not, check the following.
Keep cool mode and temp setting minimum 3 degree less than room temp.
Check indoor unit return air sensor. Disconnect sensor from PCB and measure resistance. 8 kOhm at 30C and 13 kOhm at 20C if not replace air sensor

Check Indoor Pipe Sensor Disconnect from PCB and measure resistance. Pipe sensor = 5kOhm at 25C. If not replace pipe sensor.

My weatherking outside compressor isn't big enough to handle my cooling needs. It is 1.5 ton unit, can I put a bigger ac unit onto this one without changing my heating system which is sufficient?


if your indoor unit is 1.5 ton the answer is no
if your indoor unit is 2.0 ton then you can jump to that size.
Note :your duct system may have been designed for a 1.5 ton and may need to be reconfigured for a size increase.
Your hvac contractor should know this?

Ice formation in the indoor unit


you need to have the unit checked for the amount of freon in the system this must be done with a gauge set the freon amount is obviously incorrect
also the a-frame evaporator must be sealed in the furnace cabinet

Non cooling


Check the indoor fins and air filter if dirty, so if its dirty cleaning is needed specially the indoor fins it should not be block with dirts6702929.jpg. But if it is clean then you need a qualified technician it may need additional gas.
