Can a missing SMD resistor trip my circuit breaker ?

Hello ! I'm trying to repair a treadmill I got for cheap. It didn't start at all and the first issue was a fuse replacement.

Then it worked very well but only the speed function, not the incline function. After testing the incline relays, I noticed that both of them were not working, so I decided to replace them.

But now when I start it, it trips my circuit breaker. After disassembly I noticed a SMD resistor completely broken (circled in red on the pic), and I wanted to know if this could cause it of if it's not related at all. Thanks a lot !!
