I am probably the only one this happens to.
I have a compressor in the shop. Some time ago it quit working so I went to a big box store near by and bought new one. When I got home I tried the old again and it worked. I took the new one back and got a refund from the store.
Yesterday it quit again, I checked it to see if it would start and nada, so I went to the store again and bought a new one. When I got home, I tried the old one and at first it would not start, but I picked it up dropped it about 6" onto the shop floor, and it started. Now I have two compressors.
I will keep two and I bet they both will run forever. One is new in a box and will stay that way.
