21. Good morning! I did indeed just replace the capacitor.

When it blew, everything shot into the plastic housing and missed all the other circuitry. The capacitor clips in, so it was replaceable without soldering. But I also had to replace the door spring, which was broken -- and which had been causing the motor to work very, very hard. But it was one of those completely enclosed type of springs, so I couldn't tell it was broken. I've got a typical spring on there now.

Thanks for chiming in, and welcome to DU!

Garage door opener: pop & smoke [View all] Beartracks Oct 2024 OP

The magic smoke got out ?? Oh no, that means it has to be returned to the factory to be refilled ! eppur_se_muova Oct 2024 #1

There was intermittent dripping onto the floor for a couple minutes. Beartracks Oct 2024 #3

Hard to know if that was lubricant or electrolyte. In either case, I'd try to wipe that board. eppur_se_muova Oct 2024 #5

The capacitor blew its top. Beartracks Oct 2024 #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 2024 #17

Sounds possible. Blown cap on power supply. Sure could be. bullimiami Oct 2024 #2

I installed it in 2008. Genie brand. Beartracks Oct 2024 #4

Genie does sell replacement boards, if it's not discontinued. eppur_se_muova Oct 2024 #7

Hey, thanks for this info. Beartracks Oct 2024 #9

It's probably the dielectric material in the capacitor. cloudbase Oct 2024 #10

If so, would it be a solder -type replacement? Beartracks Oct 2024 #11

Maybe. cloudbase Oct 2024 #12
