Not getting heat

DRYER OVERHEATING:

Heating Element
A defective heating element can make a dryer too hot. If the element partially shorts out, it can produce heat all the time, regardless of whether the dryer is calling for heat. Remove the heating element to inspect it. The coils should not be touching each other or anything else.

Other Causes and Conditions
Air Flow Problem
Dryers need good ventilation to work properly. If the vent is clogged it can make the dryer too hot. Clean all of the vent tubing thoroughly.

Cycling Thermostat
Although not common, a defective cycling thermostat can make the dryer too hot. The cycling thermostat is supposed to turn on and off the heat to maintain the proper temperature. If the thermostat is defective it may keep the heat on too long. The thermostat is not adjustable or repairable, it must be replaced.

Felt Seal
Most dryers have a felt seal at the front and rear of the drum to keep the heat inside the drum. If the felt seal is worn away or missing, the dryer may keep heating and make the dryer too hot. This is not common.

Blower Wheel
A defective blower wheel will not spin properly and will not vent the hot air, making the dryer too hot. Check to see if there is adequate airflow out of the dryer.

Try cleaning out the lint trap really well and make sure there is clear airflow in the dryer vent hose (usually long silver tube coming out the back of the dryer). Sometimes lint can build up over time in the hose and impede airflow which causes the dryer to still heat up a bit, but it won't get hot. Without proper airflow, it will not get hot enough to dry clothes efficiently.

Your heating element is most likely burned out . Have you made certain all of your lint vents for the dryer are not clogged ? Also , be certain to clean the lint filter every time you use the dryer. A buildup of lint in the dryer , in the hoses & on the back of the dryer inside in between the drum & the outer covering can get so hot it will catch on fire when the heat is working , and also , without a fire will burn up your heating element.

You may need a new drum motor . It is probably burned out. ALso be certain you check you hose for the lint to escape .
I do not use high heat because it does get "too hot" and cannot be good for the dryer .

First, check the venting to make sure it isn't stopped up with lint. This is the most typical case. Also, which you probably already have done, make sure the lint screen is clean. You may have to disconnect the flexible hose on the back of the dryer to clean your vent.

Hi, Well if it is getting hot but not drying the clothes than most likely you have an airflow problem. Take off the vent hose on the back of the dryer. It will be plugged up with lint either inside that vent on the dryer or the hose will be plugged somewhere. If you clean this or just plain replace the old hose this will take care of the problem. Good Luck. feed back is appreciated.

Is your dryer electric or gas? Is it getting hot? Please check to see if your lint vent and hose is not clogged with lint. It has to be blowing good. Any restriction will cause the problem you are having. Lint will build up in the hose/venting and will become a fire hazard also. If your vent hose is blowing good then your drum isn't turning. A new drum belt is then required. If your drum is turning and it isn't getting hot you need a new element or a igniter switch depending if it's gas or electric. Hope I helped.

The heating element should be nearly the diameter of the drum and is generally round. If the box of which you speak is about 4 to 6 inches square, it is probably an electrical connection box and shouldn't be getting hot. If this box has a removable cover, unplug the power cord and remove the cover--look for loose connections. If all ok, replace cover. Does the drum turn? Start the dryer and check for air blowing from the outside vent. If not, check for plugged lint filter (wash with hot water and detergent) and lint plugging the flex-hose between the dryer outlet and the outside vent. After running for a little while, feel the back of the drum to see if is generally hot--if so, then the heating element appears to be working. Hope this helps.

you have to check your dyer vent hose and vent pipe to outside for any restrictions. #1 problem for extented drying time. it like having a backed up sink

Okay. If the dryer is running well, there's no need to open the dryer to clean it. Clen aou the lint filer and wuth a special brush get any lint out of the area where the lint filter goes. Run a brush or vaccuum cleaner hose or your hand up the lint tubing and get all the accumulated lint out. Don't forget the vent leading outside.

If you MUST go into the dryer to clean it, check for a repair manual online or at an appliance store. ALWAYS unplug it from any power and if it's a gas dryer be carefull with the gas line. You may have a valve to temporarily shut off the gas flow. Turn it off in case you break the line when moving the dryer, if necessary.

Depending on the model dryer you have will determine how you get in. There are usually mounting screws on the bottom or bottom front (someone had to assemble it and if they can put it together you can take it apart) that hold the sheet metal "skin" on the frame. Once you 've removed the front and are inside, you'll see if the drum rides on rollers or just on a felt seal on the front. The tension of the belt may pull the drum down so be careful and watch out for sharp edges on that sheet metal.

This would also be a good time to check the belt for fraying. If it's an electric dryer there is a heat coil. Look for loose or heat-damaged wires.

Disconnect the vent tubing from the vent in back and using a brush designed for dryers, or a vaccuum cleaner, or your hand, pull any lint out of the dryer vent hose and the dryer itself. You might lube the rollers if it has any and check if the drum rides on supports or a felt seal that might be wearing down. And give the lint filter a good cleaning. Check it for holes, tears, and other damage.

Once all the lint is gone, and you find the spare change that dropped into the bottom, and maybe found that missing sock, you reverse the process. Put it all back together, making sure the drum spins freely by hand. Reattach the vent hose, and then plug it in, (turn on the gas if applicable), and before you shove it back into place give it a test run to make sure the motor turns the drum and the heat works.

Dryer maintenance once a year will keep it clean and running well.

On the other hand if it requires special tools, or if opening it up will void your warranty, call a qualified repair technician.
