 Okay, all I think I feel putting my hand on the compressor in the dryer
is heat building up, and the vibration from the fan.  I seem to recall I
could feel the pump a little more aggressively doing its thing than
that.  I also didn't feel any temperature differential in the
refrigerant lines.

 The fairly inexpensive tool I find most useful for line voltage troubleshooting is a clamp-on ammeter, since it measures through wire insulation and shows if devices are drawing normal, abnormal or no current, which voltage measurement doesn't.
 This is a more expensive instrument that gives me almost X-Ray vision:

 It's excellent for revealing poor connections that heat up more than the rest of the circuit and showing what's working and what isn't. I bought it to find heat leaks in the house insulation. In cold weather it shows the studs in the outside walls. I've read that they can reveal animals nesting in the walls.
 Going a step further, these plus voltage sensing can detect when something isn't drawing the current it should.

 I have one on my refrigerator, part of a project to make a sine wave inverter turn on when the fridge wants it to and shut off the inverter and its large DC idle current when the fridge turns off.
 

Its not turning, but it is generating heat.  I suspect its a candidate for what is generically called compressor burn out.  Usually they trip breakers, but not always.
If I really need to run some air I can probably swap in the other HF unit in an hour or less.  Probably take me as long to get it down and unboxed as to swap it in.  I'd rather wait until the newer bigger unit arrives, but that might be a week.  I do have a decent roll around compressor from CH I've had for over 30 years now.  My wife and I bought it at Price Club a long time ago.  Its adequate for airing up tires, running an impact, or even painting if you stop once in a while to let it catch back up.  I recently wired in a new Pumptrol pressure switch and made a new handle for rolling it around.  That was what my heating and bending post was about.)
If I can hold out until the new dryer is here I'll probably sell the new in box old HF dryer on the shelf.
