Been workin to fix the dryer for a week now with no luck. ignitor glows and lights, but flame goes out after 8-10 secs. replaced flame sensor, thermal fuse, and gas valve coils, still same problem. checked for continuity in high limit tstat, operating tstat, ignitor and all check out ok. there is no vent duct blockage. ran unit disconnected from duct and same problem. checked blower assembly duct and this is clear of lint also. can’t find a wiring diagram to keep going. timer seems to cycle properly. temperature switch has continuity in low setting and no continuity in medium and high settings.
any ideas on the next step? i’m wondering if the gas valve coils I ordered may be bad or if the valve itself is shot.
thanks
