lg mini split

[redskinsfan1973]

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..

A good Tech.

A good Tech.

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.

Lots of board problems and sensor problems............hum

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....

Care to say more? I haven't serviced a mini-split, just installed them. Or maybe ill just have to wait for my pro

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..
