If the wire has a break in it, the heating element is defective. One of the most common reasons your tumble dryer decides to blow out cold air instead of hot is, rather ironically, because it has overheated. If your tumble dryer does not have a reset button it is likely you will need to replace your thermostat and thermal overload cut-out TOC.
To test if your thermal fuse has blown, touch the right side of your multimeter lead to the right side of the fuse, and repeat with the left multimeter lead.
If the multimeter needle fails to move, this indicates the thermal fuse has blown. Once you get the dryer cleaned out, you can try running the dryer to see if it will heat but it is not likely that it will. The thermal cut off fuse will not reset if it is blown. The dryer will run if only one of the volt legs of volt power is supplied to the dryer. If your element repeatedly burns out, therefore, you should check the continuity of the cycling thermostat and high-limit thermostat.
If either thermostat is faulty, it may not switch the element off when the temperature is high and this could cause the element coils to overheat. The coils could also be overheating because of repeated power surges caused by a short circuit. That can happen when the insulation in the wiring become compromised, which can also be a result of overheating. Chris Deziel has a bachelor's degree in physics and a master's degree in humanities.

But here are three common problems and how to fix them yourself. A clothes dryer is no doubt one of the most used and most power-hungry appliances in your home. It's also essential for making sure you have clean clothes for work or school.
Who has time for hanging clothes out to dry anymore? When your dryer stops working like it should, things can get ugly fast. Clothes pile up and soon you're wearing the same shirt to work several days in a row. Fortunately, dryers are relatively simple machines and some of the most common problems can be easily fixed.
Below are three common problems and how to fix them yourself. You put a load in the dryer, start it and walk away. You return after the cycle finishes, only to find the clothes aren't completely dry. Maybe you just overloaded it a bit, so you run a second, shorter cycle to finish the job.
This may be the worst problem of all: Everything seems like it's working mostly as it should be, but the problem gradually gets worse over time until you realize the clothes are still sopping wet after a full cycle. The culprit here could be a faulty heating element.
If the heating element isn't working properly, the dryer will still spin and the cycle will complete, but it won't get hot enough to help dry the clothes. Heating elements can naturally wear out over time, but overloading the dryer, not cleaning the lint screen and poor ventilation can all speed up that process. Fortunately, replacing a heating element isn't a terribly difficult job. You can usually find a replacement heating element at a local hardware store or online by searching for your dryer model number.
Once you have the part, unplug the dryer, remove the back panel, remove the connections and install the new one. Some heating elements may require you to remove the existing thermostat from the old heating element and install it on the new one.
Reattach the back panel, reconnect power and run a test cycle to check for heat.
