Dryer worked fine all day yesterday but today there is no heat.
Heating element glows for about 30 secs then goes out. any Ideas
This may sound silly, but it is mot meant to be insulting in any way: Is the gas turned on?
Check the flame sensor. You can do this by disconnecting the wires from it and taping them securely together. Make sure they do not come into contact with any metal. If you get a flame, replace the sensor. If still no flame, the coils need to be replaced.
