I'm at a loss! My dryer will not heat. This is what I´ve done so far. Checked thermal fuse, cycling thermostat, the igniter glows bright red, flame sensor has continuity, gas valve coils measured out of range, replaced with new ones, hi-limit thermostat checked and thermal cut off checked. The dryer will not heat after all this. What am I missing. The gas supply is on. Grateful for any advice. It is a Whirlpool LGR5634LQ0
Thank you

Thank you Unplug the dryer, and take the 2 wires off of the flame sensor, and put them together. So basically we are jumping out the sensor. Put some tape around the terminal ends to keep them together, and to be sure they do not hit metal. Then plug the dryer in and see if it works. If not replace the gas valve.

I put the wires from the flame sensor together. Still no heat. I can fell the gas valve move when putting a screwdriver to its body and "jiggling" the timer knob. Plugged orifice in the gas valve?

Possibly. As a tech, I would replace, not rebuild Tom

I discovered, when you pull the plug on the coil with three prongs it shuts and then opens the coil with two prongs does nothing. Measuring the wires, the two prong wire measures 110V between blue and groung but only millivolts between blue and white, The three prong wire measures 110 over black/white and same over blue/white. What controls the two prong coil?

OK, here is what I discovered on mu own, Putting the wires from the flame sensor together accomplishes nothing. The flame sensor is closed in it's neutral position. When the temperature from the ignitor comes up the flame sensor opens and the gas coil will open the gas flow. If you have a wiring diagram you can see that the two coils, the ignitor and the flame sensor are basically wired in paralell. By ohms law the current will pass over the flame sensor untill it opens and the coils will be powered and open the gas supply.
