SOURCE: Will not start; makes no noise
check the humidity sensor this will prevent the motor from starting
SOURCE: Whirlpool dryer LGR7646EQ3. Burner lights before pushing start.
The heat is regulated with a Klixon mounted next to the blower housing
near the vent pipe so it can judge the temperature of the air coming
out of the drum.Right next to it is a melting type fuse. If the dryer
runs and gets too hot the fuse will melt.But the dryer will still
run. So if the fuse is good(continuity) and the dryer control(cycle)
thermostat is also good then you should have power going to the gas
valve assembly when the machine is running unless the timer is in the
no heat or wrinkle free/cool down mode. When the gas valve assembly is
energized the flame sensor mounted outside the burner chamber detects the heat from the ignitor.
When the heat is very intense then the sensor shuts down the ignitor and that frees up the power so that the coils can be fully energised
and open the gas gates. The gas comes out and hits the red hot ignitor
and you have ignition. It stays on for maybe 2 or 3 minutes or until
the control thermostat is satisfied and shuts down power to the gas
valve assembly.

SOURCE: Dryer wont run/push power-sounds like it wants to start/nothing
i get this all the time,yes it is the motor,what happens is the motor gets so weak that it will no longer turn the drum it just hums,a motor on ebay runs about $65,your model number if you want to tackle it is inside the dryer door-mike
