Benchwheel ESC problem

Hi. One of the motors on my benchwheel dual stopped working (it just kind of shudders and buzzes). It’s not the motor cos it works fine if I connect it to the other side’s wiring. I’m thinking it must be the ESC… does that sound right? If so, is it possible to fit a new pair of ESCs? Any help greatly appreciated.

check motor wiring if disconnected. other wose get new ebay dual esc

Ok, but how easy it to fit new ESCs to prebuilt board?

Not hard if it is the esc I think it is. Can you please post a picture of the esc
