This one:

 

I haven't looked at it in detail but those boards look very much like the ones that always show up in these coolers. The schematics in that other thread may be fairly close. Good catch on the bad cap. That would do it. The question now is whether it took out any other components along with it.

My challenge is what caused the cap to blow in the first place. I'm wondering if one of the fans has an intermittent short that showed fine when I tested it but not when operating.

 

It is extremely unlikely that anything on the outputs would cause that capacitor any problem at all. It is (half of) the input smoothing. It looks like a voltage doubling rectifier feeding those two capacitors so the other capacitor being short would do it or, possibly, one of the diodes.
(Or feeding it with 230V but I doubt you could have done that.)

 

Justyn - did you identify the issue? We have the same issue and I'm about to replace both control panels.

Unfortunately, I haven't had time to replace the board components or further diagnose. Small kids are time sucks.

Did you mean sinks? Or was that a Freudian slip?
