Re: dryer gets too hot
If it gets too hot with new limit you might need to take dryer to neighbors yard and blow out all lint from whole unit from the lint filter, blower, indide and exhaust hose and also check the flapper where the air goes outside
and blowing out the lint from an old dryer with an air compressor makes a BIG MESS

heaters and stoves use elements that heat up,and it does require the wires with matching resistance,that wire if u check it heats up if u replace it thats y it breaks,try a thicker wire for the resistance
Most likely the heating element,,,but there are also about 30 other items that could cause the unit to run and not heat. The first is the line voltage coming into the unit. Other items could be the thermal limiter, a burnt wire, A shorted thermostat,a burnt contact in the timer. Temperature selector switch, operating thermostat, hi-limit thermostat...a sensor, electronci control... and the list goes on. Do you have a voltage meter and know how to use IT?

First ck and make sure you have 220 volts to the dryer. It will run on 110v if one side of the breaker is bad. The other culprits are a limit switch heating element or thermal fuse. If you have 220 volts and the dryer runs just does not heat first turn off the power to the dryer and unplug the dryer from the outlet. Pull the dryer out and remove the lower back panel it is held on by several 5/16 hex screws. (not the back plate on the switch panel) Remove the back and your heater is on the lower right hand side and is inside an metal shell. The thermal limit is also on the metal shell and will have several wires running to it. And if you trace the wires from the element and this thermal limit it will go to the thermal fuse it is on the lower back slightly to the right of the dryer and has two wires run to it and is about the size of a dime or smaller. Unplug the two wires from the termal fuse and hook them together with a papper clip or just tape them together make sure it doesn't touch metal. (this will short it out) and then plug up the dryer and try it to see if it heats you do not need to hook up the vent. (make sure not to touch the back of the dryer and especially any exsposed wires. If it heats up your thermal fuse is bad replace it. If it does not you should check your heating element first unplug the dryer and reattach the wires to the thermal fuse. Then the heating element metal shell should be removed. First unplug the wires to the heating element and thermal limit switch and mark them so you know where they go. Next remove the screw at the top of the metal shell pickup and pull back on the shell to disengage it from the dryer. You can then remove it and inside is the heating element it is attached to the shell with 5/16 hex screws. Remove the screws and pull the heating element out of the bottom of the metal shell. Look closely and you should see the heating element break. The element is a coiled wire and when it heats up the wire actually grows in length and when it is off it cools and shrinks this causes fatique and the wire breaks over time. If the wire is broke replace the element. Look very closely use a pencil to move the wire slightly it is sometimes very hard to see the break. If broken replace the element and make sure not to touch the new element with your fingers this can case premature hot spots which causes the element to fail prematurely. If the wire is not broken then the thermal limit attached to the metal shell that holds the heating element is bad. Before doing any of the above you should look at all the wires in the back of the dryer and look for burnt or broken wires replace or repair them and check the dryer before any other repairs should be entertained. Before replaceing the back on the dryer clean all of the lint out of the back of the dryer and out of the dryer vent. This is very good insureance for the future of your dryer. Good Luck and I hope this is useful.
Check for burnt out heating element and electrical connections to element and thermostats. If okay check all thermostats, operating and high limit, with an ohm meter. All must be in closed position. If element,thermostats,and electrical connections good then check timer.
The element most likely burnt out. light a filiment in a light bulb, they do burn out. The other possiblity is the limit switches are no long working, you can check that by connecting the 2 wires that go to each limit switch, iff more than one limit. Or checking continuity across the switches. Unplug the Dryer first of course. If it is the limit switches it will run without, but replace as soon as possible to prevent overheating.
