hey guys welcome back to the channel so i've been messing with my air compressor this craftsman air
compressor i've got over here this thing i had another video of me troubleshooting it last
year trying to figure out why it wasn't running and i was doing some more research because it's
still tripping breakers so it looks like the last time i replaced the run compressor on this thing
i replaced it with a 50 micro farad which was a little bit bigger than the one that came with
this i learned recently even though i should have known as an electrical engineer that you
don't ever want to upsize or downsize your capacitors on your motors unless you have to
or it's an emergency situation what it is is with these single-phase motors they need the capacitor
it creates a three-phase induction inside the actual motor so you need it perfectly balanced
so you don't overheat the motor so that's what i think is happening other than that i think
it's maybe the worn bearings inside the motor that's tripping the breakers but either way
i'm gonna put in the correct microfarad capacitor today and see what happens
so if you watched my other video on this i actually had to rig
this capacitor because the last time i replaced it like 10 years ago it didn't fit inside the
housing i ended up drilling a hole running some wires and then mounting it on the outside
so we'll take a look at it in a second once i get this open
so you can see i have this 50 microfarad capacitor mounted on the outside and i actually had to rig
this bracket on because my cover i've taken it off so many times that it's kind of broke
so i had to rig this little bracket to keep the back cover on just a screw that goes all the way
back there to the long screw and a piece of metal that kind of just wedges this in
on the bottom here i just used a little piece of metal to keep that in those plastics got all
too brittle now that i got the capacitor on the outside i don't need to take any of this stuff
apart i just need to unbolt this capacitor from the zip ties and just change the plugs just in
case you always want to discharge the capacitor by just shorting the two sides with a screwdriver so
you get rid of any potential that's in here also make sure your compressor is unplugged
back in the same spot make the connections the reds
go on one side brown goes on the other side make sure we tape everything up and get this all back
you see i have all these little zip ties to kind of keep things from shorting out or touching
so i got everything secured i bent that bracket up i wanted to expose that hole that i was using
as an air vent that i had cut out last time on my other video i showed
put other cover on and hopefully this doesn't trip anymore breakers
so
whoa it didn't trip the breaker this is the first time this ever happened
double check make sure the gfi still works over here
yep everything still works it didn't trip the breaker this thing filled up to 150 psi and
shut off on his own wow maybe it was that stupid capacitor that i had oversized for the longest
time that was causing these issues hopefully it keeps on running like this let me use it for a
little bit and i'll give you an update so i just dusted out my garage and i drained this thing
down to like 70 psi i'm gonna go ahead and turn it back on see if it charges back to 150 or it trips
the gfi light is still on everything works i can test this thing and reset it and yep
yeah everything still works there did not trip the breaker i'm so glad so maybe it was a stupid
capacitor that's been screwing me all this time by oversizing it from a 40 to a 50 but i put
the correct one in and it works now i also had that stupid piece of foam here that someone had
commented on my last video about it blocking the airflow so i just go without even though you kind
of need it that's the air intake for the actual compressor to keep it cool but since you don't
get any dirt dust in there you should be fine or just get the correct one that's less dense
hey guys thanks for tuning in on this quick video on troubleshooting that air compressor obviously i
made a mistake last time when i troubleshot this thing and put the wrong size capacitor in there
now that i got the correct capacitor everything is working fine and i'm hoping it keeps on working
especially when i paint something or i need it running all the time like when i'm sand
blasting and doing all that crap remember guys for all these diy projects whether it's on your
car your house or anything if i can do it you guys can do it that's why i make these videos so
i can show you guys these simple and easy fixes if you found this video useful give it a thumbs
up if you haven't subscribed to your channel already go ahead and subscribe to your channel
to stay up to date for all my diy projects around the garage around the house or on my cars anyways
i want to thank you guys for watching all the way to the end and i'll talk to you guys next time
you
