TimberJack Posted May 9, 2023 Share Posted May 9, 2023 Got 2 CHU’s having the same problems. Both Ac will freeze up. I had a problem with the drivers messing with Freon. So now they are gone I replaced driers and expansion valves pulled vacuum an charged 3 lbs. one truck the low side line will freeze from compressor to expansion valve. Doesn’t seem to be cycling. The other truck cycles but freezes the core. Does these trucks have a freeze switch like the older ones? Quote Link to comment Share on other sites More sharing options...
mechohaulic Posted May 10, 2023 Share Posted May 10, 2023 someone pushed the temp probe tooo far into the core?? that's going under assumption the "new "iron still has that set up. Quote Link to comment Share on other sites More sharing options...
TimberJack Posted May 10, 2023 Author Share Posted May 10, 2023 I washed the core out an there doesn’t seem to be one. That’s on both truck, got me scratching my head Quote Link to comment Share on other sites More sharing options...
