Hopefully someone is/was a residential A/C repairman who has had
sufficient experience to help me identify a failing part.
The unit I have is an LG LW1000ER (electronic model with remote and
led-type display panel w/electronic air cleaning). The manual states
LW1500 series. It's a 10,000 btu model.
According to LG, because I mounted this unit through the wall not
blocking any vents and also angling down to the outside approx 5-9
degrees, they claim I have voided my warranty. So be it! I just want
to fix the problem.
Here's the syptom: The unit works just fine in every respect, except
ONE: if the unit is powered off, either by using the remote or the
power button on the unit itself, eventually it will automatically
restart itself. Could be 5 minutes, an hour, several hours. Doesn't
matter, it WILL restart itself.
I've run a dedicated line from the distrib box to a single 15A outlet
adjacent to the unit so power should be clean.
The parts diagrams I've been able to find online show TWO IC boards
mounted in the housing behind the control panel. They do not,
however, identify the function of either. My question is which one
does what so I can determine which one requires replacement. I don't
wish to replace both for costs reasons. So, if any A/C technicians
out there have ANY experience with LG electronic units, please,
please, please try to identify which part (by part number perhaps)
might be the culprit.
Thanks in advance for anyone who can help.
