Here are the symtoms:
No heat
Timer advances normally on air fluff, but when heat is required, the timer doesn't advance
Gas supply is good
Dryer tumbles, and blows strong exaust
Lint trap clean
Periodically there is a slight buzzing sound coming from the back, like loose sheet metal rattling

I suspect the igniter is the the cause for no heat, but the timer issue confuses me, also the rattling sound.

Any suggestions?


Thanks in advance.
