No heat at all. Dryer ignitor won't even glow. I tested fuse, high limit thermostats, igniter, flame sensor, two coils and cycing thermotat. All tested good, no open circuits. The coils also measured the proper resistance. Prior to dryer failure the heat woud activate for awhile only after the dryer was turned on for around 15 minutes. Now it has completely failed. The timer and controls seem to be working fine and the tumbler is rotating with cold air only. I have a theory and maybe I am off base. The Cycling Thermostat has four connection points (leads). The Cycling Thermostat's outer lead connections do show a closed circuit when tested, as they should. However, the two inner connector leads coming from the control panel on the thermosat tested as "open", NO resistance. Would this cause a signal not to pass causing the dyer's ignitor not to turn on? All the repair videos I have found do not talk about these two connections on the cyclng thermostat.
