18 Year Old Unit Up And Running Again
Used Youtube Videos To Trouble Shoot. And Found I Wasnt Getting 24 AC Volts To Works The Contactor In The Outdoor Unit. So Not Only Did I Replace The Board Because of Heat Damage to the Old board my transformer was Bad Also. Smelled Burnt. Anyway All Is Good Now. Fast Shipping And That Important Because I Live In Arizona. Why Does Every Word Have A Capital Letter When I Did This Review? Lol

I have ordered several parts - all from this supplier
It's a gas valve..it fixed the issue. The company is what I'm reviewing, they're the best.
