What happens if you bypass a fuse?
It's highly recommended to avoid bypassing a fuse, especially if you're dealing with a blown fuse. Using a wire to bypass a fuse can provoke electrical and fire hazards, making it your safest and best option to replace the fuse.
Why does my dryer keep blowing the thermal fuse?
The main reason that a thermal fuse will blow is a blocked exhaust vent. This is because when the exhaust vent is blocked hot air cannot properly get distributed out of the dryer and this causes it to overheat. So, if you give the exhaust vent a regular clean, it should stop the thermal fuse from blowing again.
Can you bypass moisture sensor on dryer?
