I changed the felt seal on the front around the lint trap. Everything was working fine put the dryer back together and all of a sudden I have no panel lights and the power button is not working. I checked the lines for electricity and I’m getting power to the unit because for some odd reason when I depress the lock key button for three seconds the LED light comes on? But no other lights come on. I don’t know what could possibly have happened… I didn’t even touch any electrical components.
