Chosen Solution
I have a WED49STBW1 dryer that continues to blow thermal fuses, and we have not been able to identify why. We’ve fully cleaned the exhaust ducts from the drier to the exterior wall.We’ve fully cleaned the inside of the machine of all lint and blockagesWe have replaced the High Limit Thermostat, Cycling Thermostat, Thermal Cutoff Switch, and the heating element itself. The dyer still gets extremely hot to the touch even when used on the low setting, and still occasionally blows a fuse. What else can I try to get this device fixed.
This sounds like the system isn’t reading the temp data right. this is keeping the coil on and thus burning out the thermal fuse. you may want to replace the temp sensor and check the wires for a pinched or wear spot. also the ends can get corroded. cleaning this off may also help.
Hi, Do you mean that you have replaced the “….Cycling Thermostat, Thermal Cutoff Switch, and the heating element itself” or not? If not check that the Hi Limit thermostat (supplier example only) is OK and also that the resistance of the heater element is OK. I don’t know what the resistance value of the heater is, but research online seems to indicate that it is a 240V 5400W heater so the resistance is ~10ΩHere’s the wiring sheet for the dryer that may also help in case it is a wiring problem
the thermal fuse opens at high temp. The heater is controlled by the temp sensor. So either the heater is overheating too fast, maybe due to a ground short, the temp sensor isn’t working or miswired, or the control isn’t controlling.
