The Coleman Mach AC on my 2008 Starcraft bit the dust last October. We were camping this last October and I heard a loud pop then smelled a burnt electrical smell. I turned the AC off. When we got home, I took the roof top unit apart and found the capacitor insides melted and the top exploded off. I replaced the capacitor and the started but the compressor never would start up again. Now that it is warming up again, I bit the bullet and bought a new Coleman Mach 3 Plus roof top unit and a new interior control panel. The installation was pretty easy, but time consuming. I had everything completed in about 3 hours. The total cost for everything with shipping was $675. We live and camp in Louisiana and it would be unbearable to camp without the AC in the summer. For us that is April to October.
