What Causes the Thermal Cutoff to Keep Going Bad on a Dryer?

The dryer has been included as a necessary safety measure since 1980 s. They are basically fuses that react to excessive temperatures.-Not current--But they turned off the power when they exploded. When the Heat cut-off blows out, you have to replace it and get the dryer to work again. If the new one blows too, you need to rule out the cause of overheating before installing another one. The hot cut off is different from the hot fuse. The fuse controls the heating element of the dryer while the cut-off line controls the motor. The dryer does not get hot when the fuse blows out, but when the cut-off blows out, the Tumbler does not rotate. The location of the deadline varies depending on the dryer model but is usually attached to the dryer housing. It monitors the temperature inside the housing and melts when the temperature exceeds its limit, thus opening the Circuit of the motor. Since it only responds to temperature, its failure usually does not mean an electrical problem. 

Many parts inside the dryer can cause overheating. The first and most obvious is the heating element itself. If short circuit, it may remain on even if the bike thermostat is off. A visual inspection may find that it touches certain parts of the Assembly Housing, but if not, you should unplug the dryer, remove the heater assembly, and test its continuity with ohrazer. If the meter shows a very low resistance or no resistance, the element is defective and you should replace it. The fact that there is too much heat in the housing suggests that the blower that pushes hot air through the exhaust is likely to be broken. If this is true, you will not feel too much air coming out of the air outlet. Defective cycle thermostat if the heat is not turned off at the appropriate temperature, it will also cause the dryer to overheat. If it does not work, the Continuity test will reveal infinite resistance. The third possible cause of overheating is the wear of felt seals on the front and back of the drum. They allow hot air to escape, forcing the heating element to remain in working condition. The primary cause of overheating of the dryer is poor ventilation, and while this may be caused by a defective blower motor, it is more common that the result of a lint filter or lint blockageclogged vents. If your pipe is made of corrugated metal or worse plastic, it is particularly possible for you to block the vents. If the vent is blocked and the air cannot circulate through the dryer normally, if the deadline does not blow, you may have a dryer fire like 2,900 homeowners per year, according to the Federal Emergency Management Agency. Regular cleaning of vents to remove lint build up is an important part of dryer maintenance.
