My condenser fan comes on and the ac line get cool with condensation forming but the fan does not come on either when in Auto Or ON position but if I turn the heat on everything works fine. Any suggestions? I am a Auto Tech so any pointing in the right direction I should be able to pick up and use Thanks in advance

How old and what model is the furnace? Older furnaces turn the fan on for A/C with a relay and for the heat with a fan/limit combanation switch. It most likely is a relay issue. If you can give me a little more info on the equipment I may be able to help.

My house was built in 1992 the unit is a janitrol

Can you see the control board?

I took the front off it and found there was a wire that shomehow got disconnected and problem is fixed thanks for the help I read a previous post of your to get an idea...

Not a problem, that's where my advice was headed next. Usually it ends up being something like a "loose connection" that costs people a service call. If you have any other problems I'm for some reason addicted to this crazy thing so I'm often here. If my advice helps please rate me with the button below... thanks!

I actually have a family member who owns an hvac business and called him 125 bucks was his estimate but in a previous post you talked about using a jumper wire to jump to connections and figured I would try it I jump many wires at work during a diag.. Opened it up and found a wire off thanks again man
