I have a Canadian model Inglis gas dryer which turns on and makes no heat. I left a load in and turned it on last night and woke up this morning witht the dryer still running and the clothes still damp. The timer never shut the dryer off and it makes no heat. I had a previous problem before with the vent being plugged. I pulled the dryer from the wall and cleared all the vents but it did not make a difference this time. I am not sure where to look next. I am not sure if the timer not shutting the dryer down has sonething to do with it, but I also noticed that when I turn the dryer on, it used to make a little buzzing noise while it started and now it doesn't. I have searched all over for a wiring diagram schematic but cannot find it in/behind the dryer. Any help is appreciated. Thanks
