I got a fermentation fridge that doesn't get cold (used to work until recently), and there is no air flowing through the inside. If i plug it in, I can hear a hum, but no air movement. If i put my hand RIGHT NEXT to the vent on the inside of the freezer I feel a little cold, but no air flow. The light turns on when the door's open.
I took off the back panel, plugged it in again and the hum I hear is a fan blowing at the compressor, but it seems like the compressor itself doesn't switch on.
Here's my amateur diagnosis. See if you agree: The fridge is getting power on account of the light and the cooling fan working. The compressor not turning on and the lack of airflow inside the unit indicate a bad switch that controls the compressor and airflow. Does that sound right?
Because everything is DC on the inside I have no idea what I'm looking at. White red and green wires, I presume the green is ground. But everything is not the typical AC stuff I work with in my house.
Any ideas? Or how to find the switch controlling the compressor?
Please and thank you!
