  1. #1

    lg mini split

    I have a 2 ton 13 seer lg minisplit, in cooling the unit works fine, i switch it over to heat and the blower wont come on. the pcb in the indoor unit had been changed out about a year ago and still have the same problem.. the blower work in cooling and independent by itself, no error codes on id or od units. not sure if what i need to be looking for..

    Maybe he's frustrated with the tech that tried to fix it. To be honest I would have no idea either.

    A little hint. Blowers on mini splits dont run in the heat mode till the indoor coil is hot enough.

    the indoor coil temp is 120 degrees, i dont believe it would be the thermister because i had checked it and even put a resistor in place to see if it would make a difference, thanks for the info though just got off the phone with lg tech and they are sending me another board....

    We installed 8 or 10 of them in the last 18 months. The only problem we had so far is one bad pipe sensor. So far not so bad.

    I am used to working on the larger commercial systems, they are easier to troubleshoot, because you can see all your thermisters from your laptop and, the rest of the system, i just got thrown in on this one after 2 other techs attempted..
