Dometic Refrigerator No Power

I think I know what I did. When I was washing my RV, I accidently sprayed water in the refrigerator vent. When we got to our next campsite, I turned the refrigerator on, everything seemed fine, but then about 15 minutes later, the power went out. I checked the fuses - 3 and 5 amp and they were OK. But when I checked the 15 amp, it was blown. I replaced it thinking I solved the problem. Well, it still did not work. I checked the 15 amp again and it was OK but still no power. No lights, fan, no electricity at all to the refrigerator. Could it be the board, how do I know. I am now going to replace the 3 and 5 amp, even though they are OK. Any other suggestions?

Thanks,

Reggie
