Our dryer will run and blow air but will not heat up anymore.
the limit thermostats are tripped. unplug your dryer before you do anything. there is an access panel on the back of the dryer over the heating element. some of them are resettable, they will have a red button in the middle. press them one at a time. if you hear one click, that means you found it. put the cover back on, plug it in, and check it. some of the limit switches are not resettable. they are like fuses that blow one time and have to be replaced. you will have to check them with a volt meter. they usually blow because the dryer ducting in your wall is clogged, and there is not enough airflow to take the heat away from the heating elements. the thermal limits blow to keep the dryer from catching on fire due to the high temperatures. If you dont resolve the airflow issue, it will blow the new thermal limits also. take it with you to the appliance store, along with your model number to make sure you get the proper replacement.
