I've had this Hausfield compressor for quite a few years. Since I've
been using the crap out of it with my nail guns here to get the house
done it is showing it's years. Recently I've run into trouble getting
it started. I will flip the switch and it will hum and through the
breaker. If I give the belt wheel some turns it will usually finally
get started. It may start again the next time or it may not.

I've looked on the motor to see if there are any brushes. Don't see
anywhere there are any. It has two cannisters at the top which may
hold a capacitor. Could the capacitor cause a problem like this? There
is oil in the compressor motor. I'm going to try and change that to
see if it does any good.

Do any of you mechanical giants have any idea what could be looked at
that could be causing the problem?

Generally when a starting capacitor goes, it goes for good. The motor
can be started by spinning it. Have you noticed if the unloader valve
is working? That is the sound you hear when it shuts off as it lets
the pressure off the cylinder head. If it does not do this the motor
has problems starting. Of course the starting is harder if the
compressor is working in the cold.

You have what is known as a Cap start, Cap run motor.

These motors also have a centrifugal to connect the start cap when starting,
then automatically switch it out when the motor is running.

Sounds like the switch is acting up.

It's a PITA to replace the switch without the proper tools, but can be done.

I'd probably pull the motor and take it to a motor repair shop.

YMMV

Sometimes a well-vectored- velocity and pressure enhanced- flow of air
can dislodge an overabundance of deposited unwanted debris from the

In other words, blow the crap out of the switch with air.

I have had the pleasure of experiencing a re-introduction of a faulty
apparatus in the functional equipment line-up.

In other words..that **** sometimes works.

Hi Gerald,

I can hear that slght release of air as it shuts off. But it starts if
I spin the flywheel.

Ah, Lew you may have hit it for me. Will this centrifugal connect
intermittantly work? Because move the fly wheel a few times.
Especially when it hasn't been used for awhile.

Thanks Robatoy

I've always been a bit weary of using compressed air on electrical
motors. They say you can force stuff into areas that can cause more
problems. I'll use this as a last resort before I take the motor to a
shop.

Yes.

If you can spin the flywheel and the motor then starts, you are a
functioning as a human start capacitor.

Try blowing the crap out first, see if that helps.

The switch is located on the drive end of the motor.
May be a little tough to get at.

Maybe a wee dram of the rum in the eggnog?

The Starbucks is across the London Road from THBC = Teahen Home
Building Centre/ used to be called Beaver Lumber) NE corner of the
Zellers' Plaza.

If a motor is 'open', as opposed to a TEFC, if the dirt can fly in, it
can fly out. Try about 50 psig.

Well, I'll certainly drop by when I'm
out on London Rd. If the Sarnia SB can
get me talking like that, my family
won't recognize me and I may get a few
hours' rest during the holidays.

It's Sat. morning and I haven't had coffee yet. But does anybody else see
the humor in having to get the air compressor started before you can "blow
the crap out of the air compressor"? Just a stray thought. Larry
