Nomad 2, stay on! dang you

Intermittent connection is a wiring issue. You have a bad wire termination. 

I know it is a pain to have to box it up and send it back, plus the additional wait, but for what you paid for it I would want it working like it should. I would send it back, somethings not right.

I GOT THIS i think. mine does the same. open the drain valve until the red meter gets to about 19. then close the air drain. works for mine.

now the garage temp is around 46 degrees... would temp have an affect on it?

In the telco industry they call this a "high open short". As temperature increases metal expands, as it decreases, metal contracts. This is true for many substances. If it works properly in low temperature but fails to function without tapping and jiggling the unit there is a strong probability you have loose wiring. The open bleed until a certain temperature is reached likely works because if the compressor isn't actually compressing the current draw is low.

Based on the data presented, Jim is correct, and you should return the unit for repair. Eventually assuming enough arcing carbon will build up and the work-around solution proposed will no longer function. You may be out of warranty at this point.

Happy Friday and hope this helped.
