We made a BIG mistake in December and purchased a new dryer with "electronic" moisture sensor. It's still under warrentee but with the trouble we have had these few months, I'm morally certain that I will have to buy the extended service plan or go broke on service calls or overprices repair parts.
The techs have put in THREE timers, THREE "control boards", and one "operating thermostat."
My question for this group is on the details of the operation of the "control board."
Functionally, the board will pass power to the timer motor when the sensor says the clothes are dryer. Problem is that 3 separate "control boards" continually say the clothes never dry.
I am hoping that someone out there has access to a schematic of the "control board." From what I can guess from the dryer schematic, it's kind of scary! The dryer uses 240 for the heater and 120 for the motor/timer/"control board"/etc. It's connected for a 3 wire ourlet (neutral/ground are the same). The "control board" has connections for "chassis", neutral, Line !, timer motor, and sensor. When it's satisfied, it must connect the timer motor to neutral. It must function with separate neutral as well as with neutral/ ground(chassis) being the same. While it's still under warrentee, I don't want to take things apart but it seems to have a 3 wire device which I suspect provides the path for the timer motor, a mess of 2 wire components with axial leads, a small electrolytic cap, and a 14- pin DIP IC.
Does anyone here have a schematic of a "typical" control board?
Again, a new one is under order and the repairs are still in the hards of the technicians. For the time being, I just wanna know for myself WTF is happening.
Thanks in advance
