We have noticed over the years that many of our customers email us wanting to purchase a heating element because the dryer takes too long to dry their clothing. When you think about this, it does make sense (older cars don't run as well as when they were brand new), old dryer elements don't heat as well as brand new ones would. The fact of the matter is, (in most cases) if your heating element does get hot, it is good. Most dryer "Too Long To Dry" or "Poor or Low Heat" complaints can be traced directly to a clogged, restricted or kinked venting system.
The first thing we always tell ours customers, whether they are emailing us or calling for a service call is to remove the vent hose from the rear of their dryer and run a load normally. If this solves the problem then we instruct them to take all the venting apart and clean it from the dryer end all the way out to the exhaust outside their home. Take special care when cleaning the outside assembly. Some of the assemblies have a single door which must swing freely.
Other types of outside housings have multiple little flaps and all of these must be free to open and close easily. A poor venting system will shorten the life of your dryer, plug up the blower wheel and clog the duct work inside your dryer. Lint inside your dryer is one of the most common causes of motor failure. So when you are finished cleaning your duct work, make sure your venting system is short, straight as possible and not linked anywhere at all.
Below is a general manufactures suggested length and diameter chart to help you choose which type of vent would work best with your dryer. If we can help you further, don’t hesitate to email us at firstname.lastname@example.org or visit our website at http://www.affordableappliance.com
