We bought this unit in 2019 and a day ago it started to make the following noise:
~every 10 minutes there's a
- compressor and blower turn off
- a loud hum for ~5-6 seconds
- then a short time later the compressor and blower come back on.
my understanding is that this sequence is fairly normal. I'm thinking that the click and hum is supposed to be the de-icing of the condenser. And it seems that this isn't working correctly and the ice blockage is causing the air flow to not get up into the refrigeration portion.
any thoughts or help would be greatly apprectiated.
