That isn't the best idea actually. It is much better to keep all the parts for one to fix yours. There comes a point when it's a waste of space to keep extra equipment around as backup. I can get all of the parts for my dryer here locally, but I am going to grab some extra parts that would go bad to cut down on our time.
Even with our old dryer, I could fix it in under 30 minutes when the wires burned off. The panels took a little longer to replace, but if 1 was down, I could bump the temp on the rest and run for a bit.
One of the smartest things I did was put a quick connect fitting on the air lines outside, so I can hook up a rental air compressor in a hurry...that way in runs through the chiller as well.
