Dryer possibly overheating due to plugged vent. They will go into a safe mode and shutdown the heater if not enough airflow. Results in starting hot but ending with a cold load of clothes! Check the belt to ensure the dryer fan is working and that the drum is properly rotating. If OK and the vent is clear then check the thermostat. Depengin on the type (Gas vs electric) there are a number of limit thermostats as well as a main thermostat. Likely you have a a limit switch kicking in to shut off the heater. Normally from lack of airflow (plugged vent, fan broken, etc...) Once unit cools down will start back up but shut down again once the heater comes on. Also check to see if the heating element is shorted to the side of the metal case. Will heat up and be intermittent.

I'm assuming this is an electric dryer. The following link will hopefully assist you in narrowing down which component may be defective in your dryer:

Now...before you go tearing your dryer apart, take a voltage reading at the wall receptacle first. A reading across the two hot leads (the long narrow slots) should read 220-240 VAC. If its only reading 1/2 the voltage (110-120 VAC) one leg of your primary voltage is missing. This means you may require an electrician to check your outlet for burned or broken wires. The reaosn the dryer will still run is because the dryer motor only requires 110 VAC to run. The heating circuits, however, require 220 VAC. This will give the symptom of a dryer that runs, but does not heat.
Typically, there is a thermal fuse and/or thermal cut-out located near the heating circuits. This component acts as a fuse and will blow when the heating ciruits overheat. The information in the link I provided will give you all resistance check reading for the components.
If you require additional assistance, please let me know. I hope this helps you.
PS If this is a GAS dryer, please post back and let me know. Your possible bad components will be different from an electric dryer.
SOURCE: dryer not getting hot
if you not technicail dont try,,,unit needs to be plug in for some tests...warning,,to start im thinking unit runs but dont heat..chech your operating thermastat first ,,next check yiur hi limit thermestat..they should be closed,,if good check your ignitor there should be 110 present..
SOURCE: my front loader dryer stopped heating,
have a electrician inspect the circuit going to the dryer as it might not be providing proper current to operate the dryer
SOURCE: Whirlpool dryer gets too hot and won't cool during
check to see if your heater element has been grounded (broke and touching housing) and if not, replace your timer
SOURCE: I have an LG DLG0332W
Hi,
If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes it is still not working properly.
if you dryer is gas check out this gas no heat tip....
If you have an electric dryer, you can have many different things that can go wrong causing the dryer not to heat.
check out this electric no heat tip...
