Every thing works but the oven wont heat at all.
You will want to check the voltages at the control board and put the unit into bake and check the bake element to see if there is 240 vac getting to the element. Most likely either the double relay 9751948 or the control board has failed.
what does a thermal cut-out do?
Answer Johnny , A thermal cut out's purpose is to open the circuit and remove power to the heater or motor(depending on which circuit) should the dryer overheat. It makes the machine inoperable if it opens, and should not be bypassed, except for test purposes, it has to be replaced. Good Luck
