I had the same problem a couple of weeks ago. Not sure if your elec motor is the same. Mine wouldn't work at all, swapped switchs and nothing. I pulled the elec motor out(3 screws) and removed the cover that covers the gears, cogs or whatever you call them. I thought the motor might be bad but a plastic piece inside the gears had broke up and binded up the the motor. I paid $20 for a gear set and greased all the rails and it works great now!
