Dryer spins but doesn't blow hot air to dry clothes

Very likely.
Here's why.
Because of the real danger of overheating and fire, dryers are "loaded" with overheat switches which will shut thr dryer off if they get hot.
One reason is that lint catches fire so easily.
Here's hoping you problem will resolve soon!

What is the model number of your unit?

I would check to see that the lint/filter isn't completely clogged up. This could make the dryer warm without allowing it to do its job of drying the clothes.
Also, is the drum spinning? If not, it could be indicative of other problems.

You will need to check all the duct work for lint buildup. This is the reason clothes won't dry or take a few cycles to dry.

You need to clean your dryer vent. The dryer will get hot but if it cant circulate the air your clothes will not get dry.

More than likely a bad timer assembly. They are usually easy enough to replace if you have basic mechanical skills. The part can be ordered from repairclinic.com.

Hello, does the dryer drum turn? If the dryer drum is moving. Is the dryer blowing hot air, cold air, no air at all? Now, if it's doing everything mention above escept blowing hot air then you'll need a new heating element. If not blow air, then the drum belt is broken, belt off, or the drum motor has gone south. It was put for a quitt. Which mean in New Mexico, they fired me, I don't work, no job, finished, I'am out of here, don't bury me with my wires exposed. I hope I was some help to you. have a nice day and be safe, GB. stewbison

Hi,
The cycling or operating thermostatis often the problem when a dryer runstoo hot, but there are also other things that can make it run hot also.

Here is a tip that I wrote that gives more details about why a clothes dryer will get too hot.

It really sounds like your washing machine is not spinning the clothes out enough. Have they been wetter than usual lately? The dryer could just be struggling to keep up with the heavier / wetter load as there is no reason for it to create moisture on it's own.

2 things are needed to dry clothes. 1 is good air flow. Check to make sure that the dryer vent is not clogged or partially clogged with lint. Also make sure there are no kinks in the vent hose. With the dryer running you should feel good air flow blowing out of the outside house vent. The 2nd thing a dryer needs heat. Check to see that the dryer feels warm to hot when you reach in to tough the clothes. It is possible that the heat element has partially failed. Another thing to investigate is how well the laundry machine is spinning out the water in the spin cycle. This spin cycle is used to get as much water out as possible prior to placing the clothes in the dryer. The wetter the clothes when they come out of the laundry, the longer it takes to dry them.
