I Have a Whirlpool kirkland signature dryer. It won't start. I set the dial on timer, open the door and push the door sensor and can hear the timer ticking. Reading the post it seems it could be the thermal fuse of the fuse to the door switch. Where are the panels located to open up the unit to check or replace the switches, and anything else need to be checked for this problem?

Bottom (large) back panel, held on by screws, comes off... reveals all. UNPLUG dryer first, and be careful of gas line. Most metal edges in there are sharp, so be careful handling. Top back panel hides timer/ switch controls.
Good luck!
