DV219AGBXAA Samsung Dryer - Instructions

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.

Ordered thermal fuse and cycling thermostat

On the Amana dryer, I had to remove the top panel. then the front panel to access the burner assembly. I also had to remove the gas pipe coming to the burner, because I replaced the tube burner assembly at the same time. There is only one screw that holds that back end of that gas pipe. The thermal flame sensor is on the left side of the burning chamber, with only one small Phillips head screw. just remove the 2 wires, keeping track of which terminal they belong. Just twist the sensor out of the small slot, and out it comes. The tube burner assembly is fastened with 2 screws. The entire burner assembly comes out in one piece, but be real careful not to bang the igniter when removing it. The coil assembly has 2 wires, which you cannot get wrong, because one has 2 prongs, the other has 3 wires.The local repair shop wanted 90 bucks per hour, plus parts, and I installed both the burner tube and radiant flame sensor for around $80.

The part came in very quickly. If you know how to remove the front panel, it is very easy to repair. The hard part is to diagnose the problem. The first thing to check is the igniter. If it comes on then you look for faulty limit switches. If you have lots of training in electronics and appliance repair this is very easy, if you do not I would not try this. I have 40 years in the repair business, It still took me 1hr. to find the problem. the switch was intermitted, one time the dryer would work the next time it would not. Good luck and happy repairs.

Followed troubleshooting steps. Checked thermal fuse (shorted)- OK. Checked igniter (about 70 ohms) - OK. checked flame sensor - (open) BAD (should read shorted). This part is normally shorted then opens when the igniter gets hot causing it to open and thus turns on the gas flow. An open flame sensor does not permit the igniter to turn on.
