My son came running out of the house today to get me.Went inside and found light smoke throughout the house with the smell of burning wire.After scrambling around trying to figure where it was coming from I noticed the wall thermostat on the wall had no power..I went and kicked the breaker to the AC unit for extra precaution. Can anybody give me an idea of what might have happened?I am guessing the blower burnt up and the smell and smoke is whats coming throughout the house?Its been 4 hours now and still have that smell ,not as bad but still smells.I got all the windows opened up.Luckly its kinda cool here right now so being without an air conditioner at this time of the year isnt to bad Any help would be greatly appreciated,Thanks

Hi all, I'm trying to understand how it electrical works to set a fan speed from "low, Med to High". I have four LG duct split units, not the common types you will find in the US by the way as I'm in Dubai. My thoughts, control unit is connected to a main-board located at the indoor unit, it will send a voltage or digital command to instruct the main-board to increase voltage or current to the Fan. The Fan is probable one phase with a capacitor. Now this could be wrong and it might work differently. Should there be an extra lead coming from the controller to the main-board which might not be connected. Others in the neighborhood with the same AC's can change their fan speeds others can't. Could it also be a faulty controller but than I have four faulty controllers. Sorry I don't have yet the model numbers but will go after this, just looking for a heads up. Thanks for your reply! Ed
