I've had a request to talk about split phase compressor PTC start devices so I'll have some information to share about those.

Any other topics or questions, post 'em here!

Hi Scott. I would love If you can go over a mechanical timer schematic , where i still fumble around ,like one i was looking today # HTWP1000M0WW PUB NO.31-16639. a simple HOTPOINT top load washer not spinning just the pump was running i had such a hard time figuring out which wire going to the motor should send voltage signal to motor .i might sound stupid but i get lost looking at the timer chart and picturing which one is fixed ,cam, switches, maybe if you can show a cut view of a timer and relating all three ,timer, timing chart , schematic. 

I feel way more confident looking at a digital schematic 


Thanks Abe

I think we'll have time to go over the schematic and timer chart- this one is very simple so it shouldn't take long.

Mechanical timers are troubleshot electrically so the timer chart and schematic are all you need to determine if the timer is faulty. If it is, you replace the timer as a complete part. Since you're not repairing specific switch contacts or cams inside the timer, there's no diagnostically useful point in going over cutaway views. It may be a a nice curiosity thing but I don't have such an image. 

If you're going to work on simple, low-end top loaders like this machine, the key to making money is to diagnose it quickly and accurately without over-thinking it. Get in, troubleshoot, quote the job rate, implement the repair, and get out.

Would it be possible to go over testing UI interface Matrix with a meter on an older Whirlpool type dishwasher. I have been unsuccessful at testing this myself. I'm amazed that I have replaced several of these lately that people have preferred to fix than purchase a new dishwasher.

We're already going to have almost an hour on PTC start devices plus some time for the schematic that Abe suggested. Could be a long night with this one, too. Might be better to save this one for next time.  

I can tell you that on some of these models, there's a keyboard matrix on the tech sheet that you can use. On other models, the tech sheet instead lists a test where you disconnect the touchpanel connector and reapply power.
