Dan for Model Number LEC6646AW0 Hello, The model number for my dryer is LEC6646AW0. I have the following questions: 1. Why my thermal cut-off fuse is always blown out, even with a new one and a new hi-limit thermostat? 2. According to the wiring diagram, the temperatures for each device are: the thermal cut-off-352 F; hi-limi thermostat - 250 F; thermal fuse - 92 C or 198 F; cycling thermostats - 150 F. Why the highest temperature thermal cut off fuse is blown out and leave the rest intact. 3. If I bypass the thermal cut off fuse, (just connect the two wires), it works with cycling, I,e, if reached a temperature, it is OPEN, and if below a certain temperature, it is close. Thank you so much for your help
Answer Dan, it would be recommended that the blower wheel is inspected for any build-up that could prevent proper airflow. If this checks good, the element would need to be inspected for any indications of it grounding out once it heats up enough. For the thermal cut-off to continuously fail, the element would have to be heating up excessively, which can be caused by either scenario mentioned. Read More...
