Element heats, dryer tumbles, no heat in drum, never shuts off

See if you can spin the drum with little resistance or is it really hard to spin?

Try cleaning out the exhaust duct

Often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. The heating element is simply a long coil of special wire. You can check it for continuity with an ohm meter. No continuity means the element is bad and you need to replace it--electric heating elements aren't repairable.
Hi, On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel. The fuse--which is about an inch long--is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, you need to replace it. (You can't re-set it.)
A common problem is for the main wiring connection from the house, at the dryer, to burn and break its connection. Because the dryer can still tumble with partial power, the connection may be only partially defective. You may need to replace both the power cord to the dryer and the terminal block inside the dryer that the wire is attached to.

could be thermal limiter fuse in the back of the dryer. this can cause it to not heat but still the drum will turn

You either have a bad element or thermal fuse. Most likely a thermal fuse. You can access it by removing the back panel. If you find that it's the thermal fuse, you will need to replace the cycling thermostat also. When it goes out, the dryer then cycles off of the thermal fuse until it goes bad.

Remove back of dryer and take out the elament shield and replace element don't over strech it start at one side and work it around thank you for useing fixya rate me

Gas dryer? First thing to check is the ignitor underneath the drum. (You have to open the panel to see it)  It should glow shortly after the dryer starts, then the flame starts and the ignitor shuts off.  If the ignitor is glowing but the gas does not light then the gas valve coils may have to be replaced.  If the gas ignites but does not stay on either the flame sensor or the coils are at fault.

Electric dryer? Temperature sensor has failed or heating element has burned out.
