We recently had a 2-3 week heat spell 90's plus. Unit was on 24/7 during this time. working fine/ dripping water like it should. Turned it off while running. It now does not blow cold, took apart and cleaned inside, cleaned screen ( filthy )I'm wondering if shutting it down abruply caused to much oil to be in system. I am no expert, but years ago, My trailer fridge stopped getting cold. I shut it off, boiled water as hot as i could and stuck the water in the freezer and turned the fridge on full, it chased the ojl (I THINK ) and the fridgr started working, just wondering if something like that as happened. Thank you for any advice.
