My Andis model LS didn't come back on, no power. this is the second time this has happened. someone told me to open and clean the hair build up. I vacuumed the hair from the motor area & they still don't work. the first time I did that they didn't work for a while and one day I was about to trash them and plugged them in one last time, they came on and worked for a couple of years. now i have the problem again. Is there any way I can expedite the process? I do oil blades
