Question about Heating & Cooling
Air Conditioner and Heater both turn on but fan does not, turn on fan only and it blows either the heat or the cold that was just created but with no fan blowing. Turn heat or cold back on and the fan turns off again until set back to fan only and then blows fine again. How can I fix this?
Sounds like wiring issue to me. I've delt with units like this and there is a wire lead for fan only and a separate one to run the fan when the unit is cooling or heating. I'm only speculating here but I would bet money that this was improperly installed.
Dont get discouraged though because it sounds like its working (for the most part) if you feel up to the task find the manual and check your connections. Otherwise hire a professional.

SOURCE: no heat
Well on some a/c units you need to put water in a special area so that the machine can cool it down to the freezing point and blow air over it therefore releasing cool air. If that doesn't work you can always return it for a new one. Hope this helped. =)

when its flashing its in a 5 min delay mode if you wait 5 min and still flashing you may need a new stat. but give it a full 5 min.

it sounds like unit could be kicking out the low pressure switch or if it is a electric furnace it could be the sequincers
