Question about Samsung Heating & Cooling
A location - indoor unit model MH026FNCA · B location - indoor unit model MH026FNCA· D location - indoor unit model MH052FNCA I set the outdoor SW01 to 3, because 3 units are connected of possible 4. I moved the dip switch of the outdoor unit to "off" position. I set the indoor A location unit SW01 on position 0. I set the indoor B location unit SW01 on position 1. I set the indoor D location unit SW01 on position 3.I rechecked all the communication cabling and piping. Everything is connected properly. When I start the A/C the indoor fan works but the outdoor does not start and I get E2 01 error (communication error). Am I doing something wrong? Can you please help me with any suggestion?

It's possible you have a bad data wire on one of the systems. Swap the data wire or both if two with a different wire. (1&4--2&3) whatever. Whatever you do inside obviously do outside. Might have extra resistamce that is throwing the error but will be fine for a ground wire.Or do one system at a time, being sure to change your dip switch settings until you figure out the problem unit. Good Luck!!

SOURCE: control cable wires crossed
I would not do anything just yet It might be more prudent to call Panasonic help line, and explain your findings I feel that the system will not have suffered any damage if the control cables have been simply wired incorrectly if that is the problem, try and find a call number from your installation paperwork, good luck.

The LED #2 is only flashing while in disconnection or short in Thermistor (3 sec off / 0.5 sec on). If you want to change it, note: this is not an easy job to do! You will need to remove the top panel, then remove the control paneland then the front panel to gain access to the thermistor. The part isnot available to the public and requires an authorized service techfrom LG to take care of this problem. You will need a special tool toremove the front door seal spring clamp.
But you can call customer service @ 800 243 000 and see if theycan transfer you over to parts. Just give them the model and serial #and see if they would be willing to sell you the thermistor part. Youwill also need the door seal spring clamp removal tool to make the jobeasier.

These units have circuit boards inside that have lights on them. These lights come on and tell you what the problem is. I have had 4 units do the same thing that yours is doing. The result has been that the compressor has gone bad. You have to get access to the control board to see the lights. There will either be one inside the inside unit or one inside the outside unit depending on exact manufacturer date.
Good luck and hope this helps.

THE OUTDOOR UNIT HAS A CONTACTOR WITH THE CONTACTS WELDED TOGETHER THE CONTACTOR CONNECTS TO THE COMPRESSOR AS IT TYPICALLY PULLS A SURGE OF 20 -30 AMPS OR MORE..WITH THE INDOOR UNIT IN FAN ONLY THE COMPRESSOR SHOULD NOT BE RUNNING. THE CONTROL WIRES GOING TO THE UNIT HAVE 24 VOLTS TO THE CONTACTOR TO PULL IN THE CONTACTS TO SUPPLY 220 TO COMPRESSOR.
