Good afternoon all
I’m new here and hoping you can help me out!! My son was fiddling with our treadmill and switched it off from the mains whilst it was running. After that, when he switched it back on nothing would work, no motor and the LCD panel was dead.
As we didn’t have a suitable fuse, my eldest son decided he could fix things my using a paper clip to bypass the fuse to get things working again!!(yes, I know and I’ve since explained!!)
Anyway, when he did that and switched things back on the motor accelerated crazily and it tripped the house fuses!
I took a look at the PCB and saw that the fuse was truly blown. I removed it and ordered a replacement and soldered that in today.
On powering up the motor sounded like it was going to go crazy but the fuse blew immediately.
I did a bit of reading and it sounds like whatever is controlling the motor is the issue.
So, I replaced the fuse again but, this time disconnected the motor leads from the PCB. This time on powering up all was well, the LCD display panel worked fine but obviously I couldn’t use things as there was no motor control.
From a bit of research, I THINK the 2 components (MOSFETs??) attached to the heatsink have probably blown??
Do you think I’m right? Would replacing them fix things do you think?
Is there anything I can do to check them? I have a multimeter although I don’t really know how to use it or test them!
I have attached a picture of the control board.
Looking forward to your help and advice!
Thanks
Mark
