Merry Christmas!
In this video we repair a 15V 4A Power Supply for a Mini-Dehumidifier. I have a previous video on this same Peltier dehumidifier with issues from the limit switches. I had to eventually replace the cheaper quality limit switches with real OMRON limit switches with no issue with those since. I now have a failed Power Supply on the same unit so lets repair it. This is such a simple unit with nothing but Peltier devices and a fan as the main components. Other than the switches and the PS it is not much else that should be problematic. Hope you find the video helpful and thanks for watching! Happy Holidays!
