Ok anyone want to take a crack at this? On 115 volt or propane freezer is good 10-20 degrees, fridge seems to have a mind of it's own sometimes works good 38-40 degrees sometimes it's at 60 degrees. I've moved the little thermistor all over doesn't seem to care where that's at, I've measured the resistance of it shows 3,750 ohms that was when fridge was basically 60 inside. I've read a few places it should be between 7000-10,000 ohms when in ice water, but I'm lead to believe the resistance goes higher when cold lower when warm...if that were the case wouldn't it be freezing all the time? Aluminum grate in back sometimes ices up and fridge is cold then melts off and fridge gets warm without touching a thing. Any ideas what to check? Thanks Joe BTW this is a Dometic 1262 fridge, yeah I know it's old.
