Thank you. At this time no, the PCB is the least likeliest problem. You need to check and make sure the exhaust pipe(in dryer), the lint filter,blower area, and the exhaust vent(in the wall),is not clogged or restricted with lint, check for kinked collapsed flex vent or crushed vent hood,etc . Then check for a shorted heater element or wire to the element. When you replace the TCO, you should also replace the hi limit thermostat(manufacturer reccomended procedure). Part number: AP4045617
Part number: AP4045367
You'll most likely find a vent or exhaust problem(in most cases) but you still need to repalce both thermostats.

My guess is, it's somewhere near the heater or exhaust pipe, but that's only a guess. Shorted wires are the hardest thing to find in an appliance(unless the harness is burnt or has obvious damage). And remember, to replace both thermostats, when you repair the machine. Good Luck;)
