Will thermostat stop kettle from overheating and blowing thermal fuse

hope this is of some help
the thermal fuse is blowing because the unit is getting to hot you replacing the thermal fuse has not cured the problem, and it will blow again , the problem is the thermostat is set to high or is faulty / allowing the unit to go over temperature hence the thermal fuse blowing
its the control stat that you should be looking at. good luck

Unless you can take it apart and repair it yourself, it probably isn't worth the cost to have it repaired. There are several websites that sell parts, but you really have to be familiar with electrical circuits to diagnose it. Possibilities are:
1. It could be the thermostatic switch that turns it off as it reaches temperature. These are little devices with two wires connected and are in the base of the unit. these normally reset themselves but can stop working, especially if they have gotten wet.

2. It could be the cord to the unit with a wire broken at the base or the plug end.
3. It could be a thermal fuse; these are about 1/4 inch in diameter and may be hidden in an insulating sleeve near the element; they are sensitive to both heat and current.

3. It could be the element is burned out.

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.

The cycling thermostat must also be replaced when replacing the thermal fuse. The cycling thermostat's failure to cycle off the heating element results in overheating of the dryer which consequently blows the thermal fuse open.




Replacing only the thermal fuse should the dryer stops running and fails to start will result in its premature blowing or even the thermal cut-out (cut-off) located on the heater duct. Like the cycling thermostat, the high-limit thermostat must also be replaced once the thermal cut-out blows open. Refer to the parts diagram in the link below and look for item numbers 31(thermal cut-off), 34(hi-limit thermostat), 39(thermal fuse), and 41(cycling thermostat.

Firstly, you need to stop running your dryer before you do any further damage,

As you haven't specified your brand or model of dryer, I can only give general advice. It's likely that your thermostat has failed in the closed (on) position. The thermostat cuts power to the element when your dryer reaches the correct temperataure.

Most dryers also have a thermal fuse to cut all power to the dryer if they overheat. This functions as a backup safety device and this only usually trips when the thermostat fails. Your dryer is stopping because the thermal fuse is cutting power, but as you can smell burnt plastic, it's likely some damage is being done before the thermal fuse trips.

Stop using the dryer, and check/replace your thermostat.

Ok, well most thing with an element are pretty easy to troubleshoot, you need to check, there is Power to the Element, Check for any "Thermal Fuses" Check wiring to Element, essentially , at where they wires join to the elements ends. Check the Element, it should have some resistance, anything from 7 14 OHMS would be OK, usually elements fail, open circuit. Check Thermostat too, see if it is opening and closing at the desired temperature. The thermostat and brain are the only things that can stop things.

The thermal limit is a one time fuse. You will have to dissassemble the heater in the base for the kettle. DO NOT bypass the limit. IF it failed the kettle was empty or overheating. The Limit fuse is not owner serviceable.

your cycling thermostat needs changed too. the thermal fuse is your last safety measure that goes, which means your cycling thermostat is not shutting down the heat element once it detects the right temp hot air in the blower housing so it let the heat element glow until either the high-limit sensor shuts the heat down or the thermal fuse blows. Change the cycling thermostat and good luck

This maybe the thermo fuse, and or the heating element that is defective. These parts must be properly replaced for safety issues.

Usually these appliances are not worth to service.

OK, inside the unit there are three items, the heating element, thermostat, and thermal fuse.What has happened is the element got too hot and the thermal fuse opened.There is no reset button.In some cases you may run across a defective heating element or thermostat but its not common.The fix would probably be replacement of the thermostat and thermal fuse.For this, you would have to contact a small appliance repair center in your area.
