You should totally write the company. I lost the magnet and shaft out of my old #1 that I had for well over a year. I wrote them just to ask where I could buy replacement parts and he sent me both brand new pieces no questions asked. I will see if I still have the guys email. If nothing else he might be able to tell you how to fix it!
I found the # it is 866-493-6787 and I dealt with a guy named Frank Moore. Hope this helps.
