Glowing Red in Dryer

This is probably normal. the element has a fine wire inside the tube that you see and depending on where it starts in the tube it will start glowing from there.

I'm not familiar with the T313vw, however, if it's an electric dryer, check the element and make sure that the element isn't grounding out to the chassis. You can check it with an ohmmeter set to check continuity by unplugging your dryer and disassembling it a little to get access to the element, then disconnect one of the leads to the element and place one lead from your ohmmeter on the terminal you just disconnected and the other lead to the chassis ground. You should have NO continuity. If you read a short, then your element is grounding out and needs to be replaced.
Barring that, a bad operating thermostat can cause similar problems.
Good luck!

Do a continuity test on lower bake element.

T'he glow you saw was on the back wall in the dryer behind the a grated area if I'm correct. What you saw was the heating element, or a reflection of it while it was on. The element glows bright red when power is being applied to it to function and is housing is made of sheet metal so it does carry a reflective quality. If you really want to make sure that the dryer isn't over heating, which I don't believe it is due to the fact that would mean the high limit thermostat has failed in a way that I've never really seen, take the vent off the back and using a digital thermometer check to see how high it gets before the machine cycles off and the temperature drops.

Sounds like heating element is grounded out if it's still actively glowing after opening door.

the orange glowing is the element, since there are safety features on the dryer I would not worry about the glowing as they are coils and glow. I would probably clean the dryer inside and out off all lint, thus ensuring that the air flow for the dryer is not restricted. Hope this helps Tim

this would be the heating element, and as long as the thermal fuse is not bypassed it is all good. You might want to clean all the lint inside(taking the dryer apart) and outside(vent tube) of the dryer, this should be done at least once a year if not twice depending on the usage. The thermal fuse is a safety feature which senses temperature and blows(one time use) thus preventing a fire. Hope this helped Tim

change your valve gas coils

No the first thing I would check is the vent going outside may be cloged the air going across the heating element should keep it from glowing real bright

The element sometimes will continue to arc inside after it burns out. It's 220 volts jumping across the break.
