customer couldn't understand why i said he needs a new evaporator.

had a walkin cooler down call yesterday at an indian restaurant. first thing I do is pop into the box to make sure the fans arte running=g and the solenoid valve is energized.. saw the evap coil and about crapped my pants...the Bohn evaporator is only about 10 years old but all that spicy food and produce left in the cooler uncovered did a number on it
