Guys. (long story)
I replaced a blower motor in an inflatable spa about 6 weeks ago. I couldn't find the exact model as it's a cheap chinese thing, but i did find a blower motor very similar. Incidentally its a 125mm vacuum cleaner motor.
Yesterday I'd had the top off the pump housing to resolve a small air leak on the blower, which was causing a whislte.
Every thing reassembled OK, and was put back in to service.
A very short run on the blower to test functionality, with then only the water pump and heater running. However, about 2 hours later smoke started billowing out of the pump housing.
I've stripped it this morning to find the 2.0 uf starting capacitor burnt out. I initially wondered if i'd nicked something on reassembly causing a short, but cannot see anything.
I'm confused why the cap would burn out when the blower motor wasn't even running, and why after a few hours post reassembly.
The blower starts and appears to run fine with the cap removed.
I'm considering not replacing the cap at this point.
Any thoughts
