Hi, I got a wine fridge from Goodwill, a HVT18DFBB. Its thermoelectric coolers did not work, so I bought new ones and hooked them up (there's 2 temperature zones). The temperature in the 2 zones were able to get down to 59F but no cooler. Then the only item to replace was the circuit board, so I did. I got the RF-5210-37: http://www.repairclinic.com/PartDetail/Main-Control-Board/RF521037/1567065 The problem is, I hook everything up (Fans, thermoelectric modules x 2, and the temperature control) and nothing powers up, no fans spinning, etc. I have a couple of general questions: Is it possible that the power input from the wall is reversed relative to the other board? If I were to plug it in reverse-polarity, wouldn't those large caps explode? I plug it in and get crickets.
