see this causes , fix it. God bless you, use the common sense
Check to see whether there's power getting to the dryer. Is it plugged
in? If you plug something else into the outlet, does it work? If not,
check for a blown fuse or tripped circuit breaker.
If the door switch or the door-switch actuator is defective, the dryer
won't work and you need to replace the failed component. The switch is
inside the dryer main housing near the door frame. Sometimes you need to
raise or open the top or front of the dryer
to reach the switch. Check for continuity you should have none with door open, and should have a reading when closed. If not replace the door switch
Thermal Fuse / Thermal Cut out
On many dryers, there's a thermal fuse (a heat-sensitive fuse that blows
if the dryer overheats) mounted to the exhaust duct inside the back
cover panel or behind the front panel. The fuse is about an inch long.
It's usually embedded in black resin and mounted in a white plastic
housing or is sometimes round and made of metal and plastic.
If the fuse has blown, it has no continuity. When this happens, your
dryer either just stops heating, or it doesn't work at all. Be sure to
inspect the venting/heating system before replacing the fuse
this is the most common reason for blowing the fuse. (You can't re-set this type of fuse.)
Often the main wiring connection from the house, at the dryer, burns and
the connection breaks. In this has happened to your dryer, you need to replace the power cord
and the terminal block inside the dryer to which the wire is attached.
