Default Air Compressor Problem - Motor Stalls

Current draw. 1/3 horse shouldn't draw more than 7 amps at 120 volts
or 3.5 amps at 240 volts.


Nameplace current rating is 6.0 amps (I'm running on 120 volts.)

I measured about 5 amps at startup (0 psi) rising to close to 6 when
it stalls. When it stops turning, the current actually drops back
closer to 5 amps, then increases as the motor starts turning again.

The motor is also hot to the touch after pumping all the way up. I can
hold my hand on it for maybe 6 or 8 seconds. I don't know if that's
different from how it used to be, though.

Thanks!
