I have this mini-split system. Actually I have 3 of them, LGs. I was
away Saturday, I come home and the house is warm. I see the indoor
units on one system flashing error codes. I look up error codes. The
code tells me "Outdoor unit condenser coil middle thermistor has
disconnected or shorted out." OK fine, I'll order a new thermistor.
There are 2 thermistors, neither of which is called "condenser coil
middle thermistor" and the parts diagram is no help. I have downloaded
the service manual and of course it does not specify which of the
thermistors is the "middle thermistor" per the error code. There is some
convoluted process to test whether a thermistor is working or not,
requires setting various temperatures etc. Incredibly time consuming and
fiddly. And I don't even know why a thermistor would fail but there you go.
So I call LG parts number and after spending hours talking to a coupla
customer service people and waiting on hold to finally get transferred
to tech support because all they can tell me is that there are two
thermistors (duh) and they don't know which is the correct one. I
finally get through to a tech support guy who is rude as hell, all he
wants to do is give me a number to call to get a tech to come out and
figure out what part needs to be replaced. No thanks. After going
around with him I finally tell him I have one question for him to
answer. OK he says. I ask him which of these parts is the "middle
thermistor." He doesn't know. He tells me I should replace ALL the
thermistors in the system whether it is 5 or 3 or 2, that is what the
tech would do. Right, that would probably cost me $500 for a guy to
dick around replacing a $23 part, or a $32 part if he would even have it
or know what to do, and he would charge me $150 per part plus labor etc.
Anyway I ordered 2 thermistors off Amazon that should be here in a week
maybe, or sooner. Bah.
This should not be this hard. Lesson though, I will never buy an LG
unit again, their support is absolute shite. Maybe some of the other
vendors are better, I guess I will check that out the next time I need
to get another mini-split unit.
