Why is my dryer not hot enough?
I have an old Maytag gas dryer model DG9800. It takes 2 hours to dry a regular load, with some parts still being damp. I checked the vent from outside and the air seemingly went out fine. When the dryer was running, I opened the door to feel inside, and it was just warm (95-100 F). I noticed the flame went on, stay there for a few minutes, then went off. Such happens a few time during the drying process. I assume it would be hot even if the vent was clogged a little bit, so I think it is due to that the flame went off too soon, before the temperature reached the target. Is this correct, and if so, which part could be faulty? Thanks!
