Dryer rotates but clothes are cold. It seems that dryers gas doesn't turn on. It was fine till yesterday

What is the model number of your unit?

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.

Hi, If you have a gas dryer.
The most common problem with a gas and no heat is the ignitor going bad...

if it heats for a while and then no heat you have bad gas coils,when the coils are on there way out they work until they heat up then they cut out,see if you have heat when the dryer is cold,if it is change out the gas coils

I found your manual and learned yours is a GAS dryer... the FIRST check is to be SURE the gas valve to your dryer is OPEN.

There is a Troubleshooting section, but NOTHING about no heat?

Know that LOW gas pressure CAN be a issue too!

I did find this:

"If the dryer no longer heats then the heating element may have failed, but it is not the most common cause. The most common cause for a dryer to stop heating is a blown thermal fuse."

The SECOND Link will be VERY helpful...

More help?
Cause 1 Thermal Fuse
Cause 2 Gas Valve Solenoid
Cause 3 Igniter

IGNITER

If there is a copper line feeding gas to it, PULL THE DRYER WAY FROM THE WALL AND TURN THE GAS OFF AT THE VALVE IMMEDIATELY!

Natural gas and copper do not mix, and the copper line will corrode from the inside out.

Now, on to the problem, it's very likely the timer has failed IF it does not rotate all the way through the drying cycle. If it does, and the clothes do not heat up, then reply back what you are experiencing and I will give you move help.

I have a Maytag Atlantis Gas Dryer that will turn on, rotate, but will not get hot and dry the clothes. A load of clothes in the afternoon, didn’t dry, tried again but didn’t dry – went to bed after putting on auto dry - next morning the dryer was still rotating and didn’t turn off. No hot air – only cold air.

soulnds like the belt pooped, or broke, remove top you should see the belt wrapped around the drum, if not you need a new one
