It was working great, we turned the furnace in the off position on the wall, and now it won't start! I've reset the breakers over and over, even waited an hour, thinking time was of the essence... still won't come on. Old units: Luxaire inside unit Model ECC030GKA, Kenmore outside unit Model CA5030UKBl. Electric. Is there a reset button someplace I haven't been able to find? Behind a panel on the outside perhaps? Thank you!!
