Just wondering if anyone could help me out. I don't know if it is dealing with my public school system today or what i am just mind dumb. I have a M# LCA036H2BB1G Lennox roof top that another contractor tried to repair by using a 17 year old and a phone. Once they found out i had been called they cut alot of wires. I replaced all the wires and have another problem. I can get the board lights to light for fan and cool 1, but nothing comes on. I check on the far right of the board were the 24v comes in to the board and the power is there but if i check the third wire over which goes to the comp. contactor there is nothing. I believe the board is fried, although I've never seen a board go through its processes and when i press and hold the reset button the compressor will come on for a second. I had one wire that was of that was not on any schematic. It was added as a feature and it looks as if it went to the economizer. It needed 24v to operate so i stuck it on the 24v terminal. does any one have a comment it would be greatly appreciated. The original problem was blown fusses and a trans????.
