cx compalint unit is cutting off mid cycle panel time will be wrong and if she trys to start it again after it stops she said its just ticks does not count down to start. inspected unit then checked for error codes and found none. ran unit and is heating good but rear panel is vibrating bad so added a screw to it and now sounds good but unit is getting hot. checked vent outside and theres pantry hose on vent and the panty hose are clogged with lint. i removed pantry hose showed cx she has a flap on unit that works and does not need panty hose. told cx to keep an eye on unit. unit is good
