Hi All,
I would like to find an easy way to fix my dehumidifier from Homelabs. I bought this from Amazon 2 years ago and it's out of warranty now.
I have 2 of them at home and one isn't dehumidifying at all. The one currently not dehumidifying bought it in 2020 which is a new one. Bought in 2018 is still working well.
Disassemble the outer shell and run for 1 hour to see what is going on with it. As you can see in the picture, the bottom coil started icing halfway. Test run for another 30 minutes but no status changed. I checked every part that is related to this issue and I realized the compressor temperature is very hot!! I couldn't even keep touching it for more than half a second.

I do not see any signs of copper tube being blocked by the kinked.
I guess when it's not icing at all because the compressor is being too hot and even more hot when assembled the shells. As you can see in the first picture, the ice stopped right above the compressor and it was already hot.
And I tested for an extra 30 minutes and the compressor stopped working with the lowest humidity setting.
I would like to know what could cause the compressor overheating.
Is it caused by the capacitor?
To test the capacitor, Can I use a multimeter to test the capacitor?
Or is it not enough refrigerant?
Is there a way to refill refrigerant?
