Why does the thermal fuse continue to blow.

Yes, the most common cause of a dryer blowing thermal fuses is a clogged or restricted exhaust vent.

There are several things that can prevent a dryer from not heating.. Unplug Power Before checking.
Electric Models
1- Power- Your dryer runs on 220volts. 110 runs the entire dryer and 110 runs just the element. Your breaker may have half tripped. Check to see if you are getting the correct amount of power by using a ohm meter. Also check the power cord for burn marks on the plugin and the cord itself.
2- The thermal fuse can prevent this from heating. The thermal fuse is a sensor on the blower housing the measures the temperature of the air. There is a cycling thermistat near the thermal fuse. If the dryer temp gets over 190-220 degrees the thermal fuse will blow to cut power to the element to prevent fire. You can test this by using a continuity tester.
3- High limit and/or thermal cutoff. These are both sensors on the heating element housing. Thermal cutoff is at the top and the high limit is near the bottom above the heating element connectors. Test these with a continuity tester.
4- Heating element- Just below the high limit on the heater housing. Test for continuity.
5- Motor- The motor has to reach a certain rpm to activate a sinfrigrial switch inside the motor. If the rpm is not reached it will not allow current to go to the element.
6- Timer- Make sure you are trying this on timed dry. Sometimes people use air fluff and forget to change it back. The timer could also not be sending current to the heater.

Gas models
1- Electric ignitor- Inside the flame tunnel inside of dryer near where gas line hooks up. Usually if it glows than it is still good but check to see if it is sending and amp signal to the heat coils.
2- Heater coils are two valves that open up when the ignitor send signal saying the ignitor can ignite the gas. Heat coils will not open to send gas if it does not receive a signal from the ignotor. They look like two round disk with two wires running from ignitor.
3- Flame sensor- Change if you change the heater coils. The flame sensor could not be detecting the flame inside so it shuts down the ignitor.
4- Motor- See above
5- Timer See above

Hi candwloc..
If the thermal fuse /thermostat overheats the dryer will not operate.
It's located on the blower housing and it cannot be reset.
A vent clogged with lint can cause the dryer to overheat and keep blowing the thermal fuse/thermostat.
You can test it with an Ohm meter or continuity checker, if no continuity, replace it.because it is faulty.
Please take time to rate me

Make sure to have the unit unplugged.

You will need to check the thermal fuses on the dryer.they are normally located near the heating element.If you have a volt meter you will need to check the continuity of all the thermal fuses ad if you find one that has not got any continuity replace it.

I do have a picture of the locations of the thermal fuses for some dryer in my tips.To test the door switch then you will need to remove the wires from the switch and test it the same way when you push the switch in by hand the meter should have a tone or read zero this is good if there is no tone or does not read zero then it is bad.

Also make sure the unit has enough power to it.
Thanks for choosing fixya i hope this will solve your problem.

Hi


Thanks for using FixYa. As you have already checked everything else then the issue seems to be with the Thermal fuse going bad needs to be replaced. It is mounted to the exhaust duct inside the back cover panel. Also, often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. You can check it for continuity with an ohm meter, no continuity means it is bad and you need to replace it. If you have also checked this fuse already then the issue is with the control going bad and should be replaced. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

Nearly all Kenmore dishwashers have a thermal fuse inside the operator console. If the fuse blows, it will exhibit the symptoms you describe. If you post back with a COMPLETE model number (located around the tub opening with the door open), I can verify, provide you with a part number, and explain to steps required to replace it.

NOTE: "665" is the manufacturer code, which identifies the manufacturer of your dishwasher as Whirlpool.

i had the same problem with my dryer and i installed the wrong thermal fuse for gas dryer which calls for a pink thermal fuse in which i installed and it works fine also check the lint in the front of your dryer. also my dryer which is the same make as yours seems will run on the fluff cycle until i replaced the right thermal fuse. my dryer run exceptionally hot and eventally shut down and it only run on the fluff cycle for any length of time.

On the back of the dryer near the fan blower housing is a thermal fuse, if this opens up ( no continuity ) the gas burner often quits but the motor will still run. If the thermal fuse is open/bad, always clean, change, adjust the venting system and vent hood first and clean out the dryers air ducts. Sometimes it is a good idea to replace the operating thermostat at the same time.
Thermal fuse parts help link...on blower housing cover, can not be re-set, must be replaced if is open (no continuity between pins).

The thermal fuse is blowing for a reason. Over temperature condition. Make sure the vent is unobstructed all the way out and not pinched off anywhere. If that is good then have the operatiing thermostat checked and the Hi Limit thermostat. Best case for this is to replace all of them as they can stick intermittently.

You see the other switches next to the thermal fuse? you need to change these too if you have a problem with the themal fuse blowing out repeatedly.
