No heat turns on but does not heat. I thought it was the heating element but all the coils are still together.

This very much sounds like a loose connection to the heating element. If it works sometimes but not others and putting it back together temporarily fixes it. I'd double check the wires and connections to the heating element. If this doesn't fix the problem permanently it is possible the element itself has an internal connection problem. I'd then check with the supplier you bought the heating element from.

Check the door switch

ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Check to make sure you are getting full 220 Volt power to the dryer, if you are then:
Sounds like your problem may be with the heating coil. Remove the back/or front just under the door of the machine and try to locate the air duct going from the blower to the drum. Normally inside/outside the air duct you will find the heating coil and the thermostats/thermistors. Once you have located the heating coil, remove the two wires from it and check the coil with an ohm meter across the two terminals of the coil.
You should read continuity across the terminals, if not you will need to replace the coil as it is faulty.
If the heating coil is ok, then:
You can check the thermostat/thermistor one at a time by removing the two wires and taping them together with electrical tape or with an ohm meter to test the thermostat/thermistor. (Should have/show continuity)
If the coil heats up then replace the thermostat/thermistor.
(Thermal fuse.If it overheats the dryer will not operate. It's located on the blower housing. It cannot be reset. A vent clogged with lint can cause it to overheat. You can test it with an Ohm meter or continuity checker, if no continuity, replace it)
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST.
This could cause a FIRE, as you have removed the safety of overheat from the machine.

The Element you ask about is normally called the Heating Element or Heating Coil. It is what heats up, then the blower blows air over the heated coils to dry your clothes.

your dryer has a coiled unit inside that heats up...this is what actually where the heat comes from is off this coil. Your coil (heat element) has a break in it some where this be the reason for your dryer not heating up. As for VERY temp solution..one could twist this heating element together making connection but again this is JUST to be temporary ..as only should be 1 day before actual heating element to be repaired correctly. If one is mechanically inclined this is not a hard procedure with the correct common tools...and heating elements can be bought offline as well as possibly if you have a Sears repair facility close by your loction. IF not, then suggest you to call a trained tech in this field if you are not mechianically inclined or unsure of yourself.

It is most likely the heating element. If you would like to access the element, just take the 3 screws out of the bottom of the kick plate below the door and you will see the element in a canister. There should be a screw on the side of the canister that holds the element in. Remove this screw and pull wires off the element, after you have noted where the wires to the element are properly placed. Then proceed to pull the element straight out of the canister. Inspect the wire coils for breakage, If you find a broken coil wire, replace the element. If you do not find a broken coil wire then proceed to checking the high limit cut off thermals located on the side of the canister for continuity. If you find one of the thermals not to have continuity, replace both thermals. They come in a package together as one kit. Hope this helps. Dave

Its possible that you blew out the thermal fuse on most dryers it is located on the blower wheel housing. You can test the part with an ohm meter, if has continuity its good if not it's bad.

heating element is bad unplug machine access the heating element it should have a break in the coil if so twist the coil back together gently though put it back in and try it i didi it to minr 6 years ago and no problems and you save a ton of money.

if coils is heating are you sure motor isn't running or just the drum not turning ? if drum not turning suspect belt ..if motor not running but element still heating suspect element is contacting outer case ..with coil touching case 110 volts is present even without motor turning if timer is turned to heat position element will not heat to capacity but will get hot enough to eventually blow element fuse
