Hi all, I have an older GQF cabinet incubator and the temps have been fluctuating. Long story short, I think I need a new thermostat, GQF recommends a 3255 Multi Turn. I ordered this part from 3 different companies over the last few weeks (including GQF) and the money kept getting refunded. Apparently this part is out of production and is now VERY hard to find. Most companies apparently drop ship from the manufacturer and GQF doesn't have it. Today I found one! A place called Belle Farm has it in stock. She said they have several. So if anyone has an older cabinet incubator and have any doubts about your thermostat (or just wanted to upgrade to the 3255 Multi Turn), I would think about doing it now. Unless they put this part back in production, it will soon be impossible to find.
