Dam. Close but no cigar

My brother called me and said his dryer is doing everything but giving of heat. From my past experience i went right for the igniter. When i got there took the front off of the dryer and replaced igniter turned it on and we had a flame. Next day he said he got to do one load be for he went back to a no heat situation. The igniter was a cheap made in china unit. What do you think? Could it be the igniter again?

Could be a bad ignitor but could also be the gas valve coils as they are probably the most common failure point. They will usually work fine initially when the unit is cold, maybe for 10-20 minutes or even one load but as they heat up they will fail to function properly. When they fail, you'll see the ignitor come on but will click off with no gas. Could also be a venting problem and if the venting is restricted, the flame will back up in the burner tube and will trip a high limit thermostat which will short cycle the heat. The valve coils are a cheap quick fix though and pretty common so I'd try that first.

Could be. They're astonishingly fragile.
