1. The magic smoke got out ?? Oh no, that means it has to be returned to the factory to be refilled !

Seriously, I'm not sure how much "acid" is in a capacitor -- I would think that only results from the heat and reaction in air. But I would disconnect it and wipe off that board ASAP -- the residue may be something which accumulates water, and that could cause a short.

If it was just a ceramic capacitor (not unlikely in a high-power device) there may be only dust left, and an obvious burned spot on the board.

ETA: If you have the model number or the part number for the board, you may be able to find repair hints at a site like Ifixit.com. The older it is, the more likely someone has scanned and uploaded what you're looking for.

There was intermittent dripping onto the floor for a couple minutes. Beartracks Oct 19 #3

Hard to know if that was lubricant or electrolyte. In either case, I'd try to wipe that board. eppur_se_muova Oct 19 #5

The capacitor blew its top. Beartracks Oct 21 #13

That may look like good luck, but it could very well be good design. Hope it's as simple a fix as it looks ! eppur_se_muova Oct 21 #17

Sounds possible. Blown cap on power supply. Sure could be. bullimiami Oct 19 #2

I installed it in 2008. Genie brand. Beartracks Oct 19 #4

It's had a long successful life. bullimiami Oct 19 #6

Yep. Beartracks Oct 19 #8

Genie does sell replacement boards, if it's not discontinued. eppur_se_muova Oct 19 #7

Hey, thanks for this info. Beartracks Oct 19 #9

It's probably the dielectric material in the capacitor. cloudbase Oct 19 #10

If so, would it be a solder -type replacement? Beartracks Oct 19 #11

Maybe. cloudbase Oct 19 #12

Glad it's working out for you. cloudbase Oct 21 #16

Hi. Capacitor replacement was the only needed fix for the motor. BUT... Beartracks Dec 3 #19
