Dryer runs but is not heating up. Checked vent and it is not clogged

Heating element would be a possible cause. Also heat circuit runs thru fuses and thermostats, the timer or control, and motor. Make sure you have 220 volts getting to dryer.

Basic instruction
Turn circuit breaker off thit can be checked for en back on, check dryer for heat.
If still no heat, (I am assuming that the dryer runs) There is a high temperature cut out on the heating element, it can be checked for continuity. the Heating element can also be checked. If this dose not help. I would need the brand and model number.
You should check the vent and make sure it is clear, I have had a lot of dryers that blow the fuse because of clogged vents.

Check behind the dryer to make sure the tube running to the exit vent isn't clogged or blocked. Then go out side where the vent runs to and make sure it isn't clogged.

Hi,

If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes it is still not working properly.

if you dryer is gas check out this gas no heat tip....

If you have an electric dryer, you can have many different things that can go wrong causing the dryer not to heat.

check out this electric no heat tip...

Try resetting the double pole breaker. Sometimes on a 2 pole circuit breaker one breaker will trip allowing the dryer to run but will not produce necessary heat to dry clothes in a timely manner.

A dryer not heating is one of 3 things, the vent hose is clogged, the thermistors are blown, or the heating element is bad. Disconnect the dryer from the vent and turn it on to see if any heat is coming out the exhaust at all. If not then more than likely the thermistors are blown, there are two of them and they are mounted on the heating canister. They are kinda round or oblong shape with two electrical plugs on each one.

Have you checked the entire run of the exhaust vent ducting? Cleaning the lint trap is not nearly enough to keep a dryer running efficiently.

A simple test you can try is to remove the exhaust vent hose from the back of the dryer and attempt to dry a load as you normally would. With the hose removed and the dryer running, the air leaving the exhaust of the dryer should be forceful and warm (about 140 degrees). If the air flow is weak or non-existent, you have a clog INTERNAL to the dryer. You will have to inspect the air blower fan housing and ducting inside the dryer to ensure the blower fan is not obstructed in any way. If the air flow is normal and the clothes dry like they should, you have a clog somewhere in the DUCTING from the point where it leaves the dryer to where it exits your home. You will need to inspect the exhaust ventilation for any clogs or kinks.

If you can see the heating element glowing, you probably don't have a problem with the heating circuitry. If you haven't checked the dryer ventilation recently, now might be a good time to do so. Leaving a dryer in a clogged, or poorly ventilated condition can cause the dryer heating circuits to over heat to the point of failure. In addition, this can also create a fire hazard.

If you have any questions, please let me know. I hope this helps you.

There may be a clog underneath the lint trap or the exhaust vent may be clogged, if either fails try changing temperature knob to a different setting.

Vent lines that run through an attic are the worst. I still don't understand why builders install them in homes like this. To answer your question, "Yes" it is possible for the vent line to be clogged in only 2 years. When the dryer is running, the vent line is a mixture of lint, hot air, and moisture from your clothes. Over a period of time with restricted air flow, the vent line interior can become moist from condensation and lint will begin to collect and stick. In a configuration such as yours, you also have gravity working against you. Typically, what happens is the lint collects, can't be pushed out, and will fall down inside the vent line in the wall. Most manufacturers recommend inspecting your ventilation at least once per YEAR. Two years is an awful long time to go without inspecting your vent lines. Not to mention this can become a fire hazard and/or a habitat for rodents (mice love dryer lint to build nests). I would recommend once in the fall and once in the spring. It doesn't take long for accumulations of lint to form and clog your exhaust.

"Yes", I would recommend trying to run your dryer with the exhaust hose removed to see if it works better. This is the easiest way to determine if you have an internal clog or external clog, or no clog at all. I would not run your dryer on a permanent basis like this, however, as it will heat up your home and add unecessary humidity as well.

As far as the element is concerned, if the dryer IS heating, I wouldn't recommend checking the element just yet. Heat usually indicates the element is actually turning on. Elements don't usually get weak, they simply burn out. If you had NO HEAT, then I would suggest checking the heating element.

Do the simple vent test that I suggested and let me know what you find. Then, we'll take it from there.

PS Rule of Thumb: The SHORTER and STRAIGHTER the dryer vent exhaust, the BETTER.

sounds like you need an igniter
