Heat on after replacing thermal fuse. By 5-10 minute heat off

the thermocouple ot high heat limiter ====the thermocouple when going bad -or not properly on bracket will shut the gas valve off --same with high heat limiter ---before checking these parts feel the air coming out if feels restricted clean the vent tube under the lint trap filter can use a vacuum from front and rear exhaust tube

Hi,

If one of the two thermal fuses are blown you will not get heat. Thermal fuses blow (and are not resetable, they must be replaced) when the machine gets too hot. Often this is caused by not enough air flow through the machine. Check and make sure your exhaust vent is not clogged. Clean it the best you can to get all the lint, dead mice, bird nests, etc. out. Also make sure air is blowing out of the machine when it is turned on. If not you have a blower problem.
Turn the power off to do this. The thermal fuses are located on the element casing. They each have two wires coming out of them. They are about 3/4 inch round with screw ears on the sides so they are about 1 1/2 inch long and about an inch across. Goodluck, Dont forget to rate me as fixya..

you have an airflow problem. Check the vent hose all the way out and the outdoor vent hood.
a simple verification can be performed by disconnecting the vent hose from the dryer and see if this solves the problem.

I'd like you to try something easy. Set the dryer to Air Fluff and see if the dryer still puts
out Heat let it run for about 2 full minutes If you dryer is still putting out Heat get back to me

As the clothes gently toss about inside the drum, a temperature control thermostatic disk regulates the heat. It is set for 160f for cotton and it mounts on the blower housing. As air is drawn into the drum and out the backside of the dryer the heat is regulated by this control. It sends 120 volts to the gas assembly. Right next to it is a fuse. The duct fuse is set to blow at 250f. Should that control fail to open and allow for heat to build to abnormally high temps. Note: the fuse will kill the heat source only on most dryer, the dryer will however continue to run. Lint and vent blockage can restrict the airflow and make the heat inside build to dangerous levels.The control thermostat powers up the heat for a minute then shuts down for a few minutes, then repeats this all throughout the drying process, the gas does not stay on! That would burn the clothes. If both of those items check ok and the dryer vent and lint has been cleaned, I next take a look at the gas assembly. I check the flame sensor first. If the flame sensor is open the ignitor will not glow. If that turns out to be good I next check the ignitor itself for continuity. If it turns out to be good I replace the coils. Those coils cannot be checked because they do not act up until energized. Sometimes the coils will work, get hot and fail, cool down and work again. I have some repair photos: HERE

you need chek :
if your apliance is gas dryer:
1-thermal fuse.
2-sensor flame.
3-ignitor.
4-gas valve.

if is electric dryer:
1-thermal fuse.
2-heater element.

If you are referring to the thermal fuse on the tumble drier, my thoughts are that the airflow is being restricted.Cool air is meant to flow in the back air vent which cools the components. This causes air convection and allows the clothes to dry evenly. No airflow makes everything overheat and the first item to normally break is the overtemp. thermal fuse.Go from there.

thermal fuse is bad. replace fuse. clean out vent duct. thermal fuse usually blows when there is restricted air flow over heating element.

hi stella. yes the problem is with the thermal fuse. when you were cleaning the vent at the left. the thermal fuse is right there, on the air duct, a small piece of plastic with 2 blue wires to it . replace the thermal fuse . thanks the appliance doc

Okay, the little white thingy you mention is the thermal fuse. If it were to blow, the dryer would not run at all. They usually blow like a fuse and require replacement, however, I have experienced on one occasion where the dryer would shut down in the manner you mention, and it was caused by a thermal fuse that was tripping off. I couldn't explain it, but I replaced it and the dryer worked fine after that. That could very well be a possiblity. Normally, problems like this are caused by the operating thermostat going bad. That the other thingy thats mounted next to the thermal fuse. The link I sent you should have information on how to check them. The heating element should not be considered a problem at this point. It would not cause the dryer to shut down if it were to fail. Your symptom would be a dryer that runs, but does not heat. Let em know if you have further questions.
