Title a little more dramatic than need be. Went on call other day- dual evap med temp walk in froze up. Made few observations. We just took cust from another company. first off cycle timer not even in circuit 2nd and most contributing factor 2 out of 3 fan motors wrong rotation. Before installing correct motors I defrosted with hot water like i usually do when its an option. After enabling unit cleaned up and something didnt seem right Went on roof checked unit and sure thing comp short cycling on overload. Found start cap no good. There was a hole in the rubber membrne but no charring or debris. Relaced start components and she took right off. Cap and relay had just been replaced in March per date. Question is could starting against an abnormally heavy load (from the hot water) had played a role in blowing start cap? There is no CPR as its medium temp. What kind of factors contribute to cap and other component failure?
