We bought one at Lowe's back in Oct and it was working fine until recently. I'm wondering if the opener took on some snow/ice over the last few weeks (during our 20" Christmas blizzard and sub-sub-zero temps). For the last few days we've had to push the button (wall or remote) at least a half-dozen times before the door will move. Each time, I'd hear a dull whirring sound, as if it was trying to move the door. Then eventually it would get "warmed up" enough that the door would open/close. Tonight I was checking all the wires and repeatedly opening/closing it, when I heard a loud pop from the opener itself, followed by a bunch of smoke rolling out of the unit! It is under warranty, but we'll see if we are able to get a refund. I have no interest in getting a new version (same kind) of something that didn't last three months. I'm going to call around tomorrow to see if we can get a new one (different brand) installed, maybe Overhead Door. So, post your garage-related experience here!
