Samsung DV419AEW/XAA dryer wonít power on at all
« on: May 28, 2013, 11:02:51 AM »
My Samsung DV419AEW/XAA dryer wonít power on at all after I pressed the power on button (no noises or lighting). Here are the things that I checked so far:
1)Checked the outlet, got 240V and 120V on each leg to ground. So power was ok.
2)Check the power coming in to dryer and they are ok as well
3)Measure the resistance on Thermostat 1, Theremostat 2, and Theremostat 3, they all have less than 1 ohm (within spec as Samsung recommended)
4)Checked the Heater resistance approx. 10 ohms (in spec)
5)Checked the thermistor at 77 degree in the house at the time, the value is 9.3K Ohms (speck is 10K)
6)Checked the door switch and they was ok
7)Inspected the main control board and sub board didnít see any burns or marks in them
8)Inspected the Samsung dryer wiring diagram, I donít see any device called thermal fuse

At to this point I donít know what might have contributed to the power problem. Could someone give me some advices on what to do next? Thank you for your help!

1-7 is probably the fuse. (click on pic to enlarge) Traditionally all dryers have the thermal limit mount near where the hot air is monitored by the control stat. Oddly enough  it seems to be left out of the parts list.

The thermostat #1 and thermistor are mounted at the location indicated in the picture and I checked the values for these in item 3 and 5 above. I might have to take a look at this again later when I get home today.

I just replaced the Main Control Board and it didn't solve the problem...maybe the sub control board next. Could it be the bad motor prevent the dryer from power up at all?

I ran into the exact same problem .  I rarely use the dryer,  but just that one time

I throw duvet and blanket in , did a high temperature drying , stupidly did not clean the lint inside (it was a rush)

but anyways the drying was completed , I took the stuff out, cleaned the lint after, turn off the power.  everything was fine

5days later , the power button does not work at all .  I checked , it wasn't the breaker , there is power going thru the cord to the PCB .

I opened the back and checked both thermostat, they are fine . No burn mark on any of the PCB either (but I don't really know how to test the PCB without extra one around )

I dont have a diagram for model listed, but if you can verify the power is to the main (it goes here first), the sub should be the problem
