Tech sheet should be on the back.  Not sure what the F40 fault is for the Kenmore.  Maytags of the similar design had issues with the blower pulley coming off.  If that's the case when you start the dryer you'll have no air flow.  Release top panel push in clips to access inside front panel.  Front panel comes off like a Whirlpool.  Remove 4 5/16 screws holding front drum support in place and remove support.  At this point you may find blower pulley and belt on cabinet bottom.  Do not order new pulley or belt.  Resecure loose pulley onto blower with Loctite.  Reinstall blower belt.  Reassemble unit.

Ok, so it turns out yes com error.  the 3b test directs you to a dual motor design (this only had one with a belt drive off the main motor).  Was pretty useless.  the dryer was very very clogged with lint.  I cleaned all the lint out and re-assembled the dryer.  It then turned on and ran with no code coming up.  But, it did not heat.  As I moved the control head I heard the relay clicking on and off.  After inspecting the interface board with a strong magnifying glass and not finding any cracks or loose solder joints I proceeded to trace the wires and load test them.  I found no breaks or unusual resistance.  I got thinking the only thing I hadn't tried and kind of hard to on that type of plug was pin fitment.  So I tightened all the connector ends on the interface side of the board and viola!!!!  appearently the f-40 seemed to be a combo of things from lack of airflow thru the blower to loose fit on the plug on the interface board side of the blue harness.

well, just got the call from my friend the dryer is acting up again.  same code but they said if they hold the power button till the timer goes to 39 it stays running.  I assume they mean start when they say power button..... ugh.....

 

is there any possible way to decipher which board may be the culprit or is it just a guessing game at this point.  I might just tell them to but both as well as the harness.
