DV331AERXAA Samsung Dryer - Instructions

Remove 2 screws which hold dryer/washer together on back. Remove 2 screws back top dryer and slide top back. Remove 4 screws top dryer that hold timer panel. Remove 6 screws that hold front panel on..4 on top of panel and 2 inside door. Disconnect wires to door at slide connection. Unplug dryer..this is actually 1st step. Remove 1 screw on heating element (lower right). I found that by removing the red wire the element will wiggle loose and come far enough out to disconnect black wire. There are 4 other terminal connections which are jumpers that will slide out with element. Note where wires attach and remove all. Use Multi meter on highest ohms setting or a continuity tester to test heating element - thermostats - thermal fuse. They should all have continuity between terminals. Replace any that don't . My thermal fuse was open (no continuity). I replaced it and had heat..but inadequate heat. Got new thermostat which fixed problem. Video I watched said to replace them together..I guess he was right. I suggest that while you have dryer pulled out to take time to check/clean dryer vent..also flapper outside.(mine had lint built up in hinge and prevented flapper from closing letting cold air and anything else in). Parts Select has great videos/skematics and even with "snail mail" delivery part was there in 2 days. They are the best!!

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.
