When checking the thermal cut-off if it reads an open is it faulty. The unit will not heat and when i plug the unit in and jumper the thermal cut-off the heating element will come on. And i have no repair manual just shooting from the hip. Thermostats reads 2 ohms (closed) and element reads 10 ohms (closed) and thermal fuse is closed. Blower works well and the exhaust line is not plugged.

if dryer is cool and the thermal cut off (limit switch) is open then it is falty there shoud be a number to tell at what temp it opens should be an inexpensive part replace it
