No problem. I took another look at your dryer photo. The heating element is really simple to remove on this model.

Unplug the dryer. Then remove the two wires that go so the heating element. Then remove the two wires that go to the thermofuse that is on the heating element.

Next remove the two screws that hold the heating element in place.

Take a close look at the coiled wire inside the element for a broken spot.

Let us know what you find.
Hope you find our website helpful.

I don't really know hot to use this meter correctly but I turned it to one of the settings that was labeled by the omega which I think is the symbol for OHMs.  I took the wires off and tested the four pieces.  Each of them read some type of numbers, except for the top piece.

I think I read that the top piece is part of the thermal cutoff.  If that need to be replaced then both pieces should be replaced?  I wish I would have understood what I was doing from the beginning...I could have saved myself a few dollars, although the lesson was probably worth it in the end.

Sounds like you found the problem. When you have the meter set to read ohms, (omega symbol) each thermostat and thermo fuse will test as if they were shorted out, just like if you would take the two meter probes and simply touch them to each other.

It is common for the top thermostat to go out making the dryer not heat. Check the blower housing for lint build up and check the vent for lint. Then replace the thermostats, top and bottom as a set.

I looked up your model number and you will need part # 279816

You get both them in one kit. Be sure to replace both of them at the same time.

If you use the test light like you did you only PROVE you have power to those components. IF you removed one wire from each component safety and element and check between that live 240 volt wire and that naked terminal on each of them components, then that test light would work but you would probably fry yer butt doing it :D
It is best to use an audible ohm meter and remove at least one wire from each component. Each one that did a BEEP would be telling you Hay Im Good! A lot safer than getting electrocuted as WPT brought out. By the way check your vent and lint inside the dryer or replacing the limit will do not good. It will just blow again.

One other thing is the control thermostat has 4 terminals. The 2 BIG wires in it carry the load. the 2 smaller wires power up a tiny heater inside the control thermostat to make it shut down faster for perma press and delicate. Those two smaller terminals have to be tested with a REAL GOOD ohmsmeter to get a reading out of them. Disregard what you might think is a open reading on them.

I ordered and installed the thermal cutoff unit, part # 279816
This fixed my problem and it is blowing heat now.  This part came with a new hi-limit thermostat.  In my error I already replaced my hi-limit thermostat before this part came in.  The hi-limit that came with my thermal cutoff limit is a little different then the one that is on the machine.  Is it necessary to install this part?  My dryer is working, but I want to make sure I am not at risk by not installing the part.

I heavily cleaned out the vents and did have a big build up of lint.  That is taken care of.

Thanks for all the help from those that helped.  This sight has saved me a lot of time and frustration.  I know a lot more now then when I started, so thank you.

Not knowing what thermostat you used it would be best to use the one that came with the set. If the single thermostat has the same values as the one in the set just leave it there.

Those limits really need to be replaced as a pair.
