Gas dryer takes forever to dry a load

Probably 10 years old.

The burner is burning, The blower is blowing. There's no blockage in the vent or any internal air passages. And the drum is spinning.

Loads suddenly take a couple of hours to fully dry.

What else should I be checking?

Thx

How do the clothes feel when they come out of the washing machine? The last time that I ran into this in our own home, after checking the vent line, lint trap, etc., and confirming that the dryer was heating, I backed up a step, realized that the clothes were too wet from the washing machine, so changed the belt on that, and everything worked as it should again.

Did you actually remove the duct work and inspect or clean it ?
Also lint caught in the blower of an old dryer is a problem too.

After you run the dryer about 15 minutes check to see if the clothes are warm. Could be a problem with the gas coils. Flame will come on but after a short time it will go out and not restart for a couple of hours usually.

Hello Louuuuu and Welcome into the Gas Appliances topic.

You mentioned checking and cleaning venting system both inside the dryer as well as the vent ducting. Excellent... Great first step. But did you miss 2 steps in the process?

First check the flapper door in the exhaust vent hood outside. It must be easy to open and close freely. Might be not fully opened, stuck closed, etc.

Next step is to totally remove vent ducting from the dryer. Turn dryer on and note volume of air flow. Then dry a load of clothes with vent removed and note the results. Same condition? Not the venting system. Normal dry time? Problem discovered. Venting system and or flapper door and/or excessive lint still remains within the dryer. Likely in the blowers cage fan, etc.

Another often overlooked area:

My Two Cents....

Just had the same problem. The clothes were drying as if the dryer was set to the "air only" setting.
Great info so far.

After you run the dryer about 15 minutes check to see if the clothes are warm. Could be a problem with the gas coils. Flame will come on but after a short time it will go out and not restart for a couple of hours usually.
Also check the duct work, and at the outside vent, for airflow and temperature.

I'd also guess the gas coils. That was the problem for me.
Good luck with it!

Y'all gave me other ideas. Thanks.

First, I'll observe whether or not the flame re-ignites after the initial startup.

Stay tuned.

Closure:

The flame was igniting initially, then never re-lighting throughout the dryer cycle.
It was the gas coils (a set of valves that control gas flow.)

A little online investigation, and I bought the parts for $10. 30-minute fix. Clothes are dry. Momma is happy.

Thanks for the advice.

30 days later: Same dryer new issue.

Suddenly, we're back to no heat + now the dryer won't stop even when it's on the timer cycle.

I can always assume that the coils went bad already. (That's a possibility)

But that doesn't explain why when I set the timer for 45 minutes last night, I found the dryer still running at 5:00 AM this morning.

Any ideas?

Is the timer dial moving? Is the dryer heating?

Does not light at all? You need to go back and check all thermostats and igintor and flame sensors.

... So, as I'm removing the igniter to check resistance, it breaks into three pieces.

I'm ordering a replacement online, and it says "Handle carefully - as this piece is fragile." No kidding.

Anyhoo. Give me about 3 days to get this side issue handled. Thanks.

Unfortunately those igniters can shatter or crack if you look at them cross-eyed. They are very fragile.

The culprit was the thermal fuse.

Everybody knows that fuses blow for a reason. Everything I read says that it was probably a blocked dryer vent. I'm not finding any evidence to support that. But, the bottom line is that the dryer is drying. And Momma is happy again...

Thanks

Interesting...... the original complaint was takes too long to dry and that the burner was burning.

If the thermal fuse was bad it would never heat or burn.

Sorry 'bout that Chief. We changed gears half way through the thread.

Original problem was solved with gas coils. Then 3 weeks later, new issue came about. Spins, but without flame. New fuse. Everything be iree.
