I'm troubleshooting a refridgerator (Samsung- RS2533SW) that stopped blowing cold air and is now just blowing slight cool air. I pulled the back panel off and the circuit board audibly turns on (click sound- I removed the circuit board and visually checked it over with no issues), the compressor/evaporator fan works, the compressor can be heard/felt turning on and it runs for about a minute and then turns off (it cylcles on and off), and the inside/condenser fan works. Is low freon the cause or is there something I can check to possibly fix the issue? ... extra info: the refridgerator seemed to just stop cooling over night and did not gradually lose coolness/ I replaced the ice maker about 2-3 months prior and it was correctly installed/ Also, when I pulled the back panel off, I noticed some dry oily-looking fluid (brown in color) in the pan under the evaporator/ I also noticed a tiny amount of greenish dust under one of the compressor joints.
-Thanks ahead for any advice
