Model Number: DV337AER/XAA
Brand: Samsung
Age: 6-10 years
I have a DV337AER/XAA that stopped heating recently. The drum spun, all the lights and sounds worked, but sometimes it heated up and sometimes it didn't. So, last night I replaced the heater duct assembly (DC97-14486A, which includes the thermostat and thermal fuse, and heating element), the thermistor (DC32-00007A), the control board (MFS-DV327L-00) because I wasn't sure which part was bad, and I didn't feel like tearing apart the dryer 5 times to replace each part individually. I cleaned all of the lint out of the dryer and got it as close to new as I could have. When I put everything back together and put the dryer back, i ran it for about 5 minutes on "Time Dry" on high with an empty drum just to test, and it worked fine and got nice and hot. I got up this morning and put a load of towels in it and now I have no heat again. The vent is clear and free of obstructions and only has one 90 degree bend in it. Can anyone help? I'm not sure which components to check, since I replaced everything. Can anyone help? And does anyone have the service manual I could use?
Thanks!
