I have inspected the new one for rips and tears and it appears to be in good shape. I'm getting ready to pull the ACC and do the solder repairs anyway, as there are glitches in the pushbuttons, for example, need to start with defrost before the econ turns on. And the defrost default is not always heat when initially turned on. And the strangest glitch is when the overhead light just comes on by itself occasionally when the ACC is on.
I installed one made by MTC yesterday morning. It has been working wonderfully so far. Made in India.
