Dexter Stacked Dryer -- Not turning -- Display Dead

[goodgood]

Everyone,

I have got a Dexter Stacked Dryer problem. On Sunday I had a customer drying two loads of laundry. One load in the Upper Pocket, and the other load in the Lower Pocket of one of my stacked units. The dryer ran with no problem for about 15 minutes, then all of a sudden it just quite(both units stopped.) and the time display is dead/blank.

I have looked at the following:

Circuit Breaker for the unit is on, and the unit is plugged in.
Checked both fuses at the back, and they are ok.
Door switches. I cannot here the relays trip on the board when the doors are shut.
I have looked at the board and found that the Upper motor LED/Upper Gas Valve LED is on. Lower motor/gas valve LEDS, and Door LEDS are off(even when opening, and closing the door.).

Do the symptons above point to a bad controlboard(Upper, or Lower, or both?)? Or is it something else. A gas valve maybe??

Any help is appreciated trying to get this one solved.

Thanks,

GooD

I don't have this dryer to help, but have you tried contacting dexter support. they can atleast point you in the right direction. Also, swapping parts helps. Have you verfied you have voltage to the dryer with the voltmeter? I

A little further information on this problem. It is not the upper/lower control board. I swapped it out with another one from a working machine. After I plug the dryer in I still get a dead display.

I have some power to the machine as I get the Upper Gas Valve, and Upper Motor LED's on. I am going to use my voltmeter, and check the inputs from the dryer to the board to see what has power,and what does not.

I will also call Dexter this week to see if I can get some direction.

Got it fixed. I tested the inputs of a working board to the one that was not working. I found that I had voltage coming from the Upper Over-Temp Stat. Once I reset it, and checked the input I had no voltage, just like the working board I tested. I then plugged the input connector back on the board, the LEDs I had on(Upper motor/gas valve) went out, door switch LED's/display came on. I am not sure if this is a sign of the Over-Temp stat going or what. But I will monitor it to see what happens.

Dexter Support also was a help with providing schmatics, and wiring diagrams :)

That sounds great can you please post the schmatics, and wiring diagrams it would be very helpful for me and others "A" ;)

Thanks

As requested here is the wiring diagram, and schematic for the dryer. :)

Update.

Real problem is a malfunctioning temperature sensor. Upper pocket is over heating and kicking the high limit stat. It must be a malfunctioning high limit stat that is causing the power problem.

I will replace both the temerature probe, and the high limit stat. I will test to confirm my thinking...

the problem is build up of lint in the upper air exhuast chamber. It is a bit of a job to take apart and clean. The clue is the high limit problem, resetting is only a temp fix. IT takes about an hour to take the heat box apart to clean out. Lots of screws. The high limit stat is not malfunctioning. I found this problem via Dexter support at a seminar years ago, and had to clean a dryer that had this very same problem.

Pete, are these the current DEXTER production models with the single 8" exhaust vent? I just ordered 3 of them. Thanks

more than likely, but not worry, it could take 5-8 years for the buildup to occur, so not a yearly job like vacuuming the back end of ADC stacks so they won't catch the customers clothes on fire, or the inevitable falling apart of Alliance dryers after 5 years.
