DV317AEWXAA Samsung Dryer - Instructions

I verified that the thermistor was bad by testing the resistance. My manual said it should be 10K ohms at 78F. I was reading over 30K ohms. This is what caused the thermostat to blow, as the thermistor was telling the dryer the air temp was a good 30 degrees cooler than it actually was. You can also verify the thermostat is bad by checking it for continuity. I removed the screws on the top-back of the dryer and slid the top back to reveal the screws holding on the control panel. I removed those and popped off the control panel. It required a good bit of force. I then removed the four screws holding the front piece on and removed it by pulling it slightly towards me and up. The parts are located on the bottom right. They were underneath a black plastic flap on my dryer. I removed the cables and the took both parts out with a screwdriver. I replaced them with the new ones (they should only fit in the right slot) and reattached the cables. From there, reassemble in reverse of the disassembly.

I change the Thermistor 3 bracket and worked well for 10 minutes and the thermistor is broken again

*Disconnect power cord before performing this task...(1) Remove the two screws holding top.(2) Remove four screws holding control module, tilt forward, pull up and unlatch. Place module on top, out of the way (still connected by wires). (3) Open dryer door, remove two screws holding lint trap assembly, close door. (4) Remove four screws on top of front cover, disconnect door light wire, tilt front cover forward, lift up from catch at bottom and remove. (5) Disconnect moisture sensor connection on bottom right for easier access to duct assembly. (6) Remove three screws holding duct assembly support bracket in place, raise duct assembly six inches to allow the bracket to be tilted toward rear and lifted out of the way. (7) Disconnect Red and Blue wires from front of duct assembly and pull assembly carefully from the rear of the unit and out the front paying attention to the wires still connected. (8) Remove wires connected to the thermostat and thermistor. (9) Remove screws holding in both units and replace with new components. (10) Reverse process and test. *note* if the unit appears to heat but clothing still wet, make sure moisture sensor was connected (I must have forgot and got to go back in to check, ooops). Regardless, this is an easy task. Could be intimidating at first but after the part has been accessed twice its no big deal and can be done over a lunch break.
