Failure!!!!

Had a similar problem with my powerpro. Turns out the problem was the cold weather. I'm in Jacksonville Fl, which is usually relatively warm but we've had a pretty cold winter here.

for some unexplained reason, the PowerPro doesn't like the cold and simply will not turn on untill it gets warm enough. I started pointing the heater at it and giving it 15 or 20 minutes and it starts right up. Good excuse for another cup of coffee. No specific explanation from Shopsmith other than some of them seem to be cold sensitive. Now that the cold weather is over the problem seems to have stopped.

Try warming it up.

Hi and thanks for the response. Wes couldn't remember what part of Fl the other problam was but he thought The Villages was correct, but he did mention your last name. If it is cold related that could be a problem. People in the colder areas of the country would have a problem all winter.
Maybe I will make some room in the freezer and chill it for a while. I used to do that to some two way radios when I serviced them to isolate intermittents. Solid state components should work from -40 to +130 deg F with no problems. Intermittents like this usually trace back to bad solder joints cracked circuit boards or failed circuit board board tracks. Those things seem to re-occur.

[quote="wa2crk"]Rick]I worked as a Product Qualification Engineer for a few years. It was my job to test products being built for the Air Force. These items all had to pass rigid environmental tests that involved performance testing over the a very broad temperature range. We also did vibration and shock testing. We referred to it as the shake and bake.

It was not uncommon to find products that worked well at room temperature but performed poorly when the temperatures were raised or lowered. These are the subject of an engineer's nightmare.
