DFF8200W Danby fridge cooling problem due to ice build up

Hello everyone,

I have a small Danby refrigerator (DFF8200W). The freezer on top worked fine but the dial to adjust the temperature in the fridge was jammed and the temperature in the fridge rose way up. I removed the fridge inside middle panel and discovered that ice built up at the top of the middle conduct. Water seems to drip from the freezer.

When I let the ice melt and put it back, the dial can rotate and the fridge temperature goes down below freezing. Ice builds up again in the conduct within a few days which steadily increase the temperature in the fridge again.

Do you have any idea why ice builds up in the conduct? Is there anything I can do to fix this?

Redbull Mini Fridge Compressor cycles every few minutes


I have a redbull mini fridge that stopped running, and sat for a few months. Initially I thought it was the PTC, overload relay, or compressor itself.

1. PTC: no rattling sound, burnt smell, and there is continuity between the 2 holes (circled in red), and continuity between each hole and the tab circled in green.
-I assume this means PTC Is ok?

2. Overload: has rattling sound when you shake it. has continuity between the large metal part circled in green and the tab circled in red
3. Compressor pins
-~24 ohms between the lower 2 pins
-14 ohms between lower left pin and top pin
-11 ohms between lower right pin and top pin
-there are no shorts
-I read that since the values add up to ~24 ohms, it means compressor is okay?
-I did notice a ton of oxidation, leaks (see pic)

Anyway, so I thought everything above was Okay as above.

The temperature control is adjusted in the back, it’s attached to a PCB board. I noticed that the starter relay on the PCB would engaged when powered, it also rattled. So I replaced the relay on the PCB. I also replaced a slightly bulged capacitor on the PCB board as well.

I plugged it in and it fried up!

The fridge itself can cool down to 1-5 degree Celsius depending on the temperature dial.

However the compressor runs for 2 minutes, then off for 5 mins, and repeat this over and over. The compressor is quite hot to touch.

I only let it run for a few hours as I thought the compressor cycling was too frequently.

Sorry for such a long post, but does anyone know why it would be cycling so frequently?
I am thinking is it the capacitor overload (ohms okay i think?), or is the compressor bad/low in freon (due to the oxidation/leaks?!)

thanks a ton!
