slow motor start?
by: Doug in s.d.ca.

Or is the motor going, but the pump isn't?

I take it you have the DeWalt compressor that comes up on Google when you look for the 5HP model? The motor has three external covers?

If not, what's the model number?

If the belt is good, and it's the motor starting slow, then a good place to begin would be the start capacitor.

How? Look here:
