I got a FREE 800lb Q series flaker in mint condition from a fellow refrigeration guy. He had issues with it at a produce dept. and called factory tech support and they told him it had a pinched/collasped evaporator tube.
Machine will run for awhile and lock out on discharge thermistor.
I have not hooked it up and tested myself but i have never heard of a collasped tube issue.
Anybody come across this issue before?
