Trying to Fix - Oster Food Processor - No Power

This is not a tutorial video, but I troubleshoot a small Oster Food Processor I received free from Craigslist.
Complaint - Intermittently works
Can I fix it?

I am sure I will never need to repair an Oster food processor but I sure like sitting here watching you do it. Well I learn some stuff sometimes but just mostly sitting here watching you fix broken things is quite relaxing and fun just to come along for the ride. I thank you for a relaxing hour.

Good man and good work thanks for that

O cara é muito orelha seca. Eu vi de cara que o aparelho é de motor corrente continua, por isso tinha uma ponte retificadora.

I have one with no power either. It's the FPSTMC3321 model. Is it worth trying to get it fixed? Thanks.

Just bought one and it won't power on
