Unit exactly one year old. Was interruped by lightning strike last night. Afterwards air handler blowing, but not cooling? Turned unit of at temostat, waited a few minutes, turned back on and unit (both the airhandler and condensing unit) ran for about a minute, then air handler died. Compressor still running? Now the compressor will run while lowering the temp, but the air handler is dead? Tech came to our house this morning and said that both the air handler and compressor receiving power - just the air handler will not operate. They check the fuse on the circuit board, it was good. They are suspecting either blower motor or circuit board is bad? Just one year old?

Hello, if you take the L1 wire and jump it with tje high speed motor wire you can bypass the board, if this turns on the motor then you board is fried. If it does not work thenthe motor is shot and muat be Replaced. Also make sure the capacitor is not damagec.

Marion, if there was a lightning strike and then a power surge when the power came back ON, I don't doubt what the servicemen had to say. The age of the unit plays no role in it, when something like this happens. Power surges can be killers to electrical appliances. That's why it always wise to turn the unit off during a power outage. Just ask anyone who was in Irene's path a couple of weeks ago. Power went out for days & weeks for some, when it came back ON, electrical appliances were damaged or ruined or started house fires.

Hope this helped you and thanks for choosing FixYa.
