Garage door opener: pop & smoke

[Beartracks]

So there I was, working my garage door up and down a few times to spread around the white lithium I'd used on all the hinges and along the track, when there's a : OP:: and then smoke whisps out of the motor as it buzzes and tries to keep moving, and liquid drips out of the housing. I thought at first somehow the grease had tracked in, but no -- this sounds the likely scenario:

"When a capacitor goes wrong, it usually makes a loud pop sound like a miniature bang. In such an instance, smoke and acid from the capacitor spill all over the logic board, causing more damage to the circuitry."

I'm gonna go out on a limb here and presume this means I am in the market for a new opener? As opposed to, say, fixing this one...

I just hope I don't have to install a new track. That's kind of a pain.
Edit to add: Oh, crap. Never mind. I remember the track with the whole motor. Dangit. At least holes are already drilled.
