Re: no heat no blower air
Your heat coil has burned out. They are pretty easy to replace if you are handy with tools but if not have a repairman do it it is usually pretty inexpensive. I replace them for about 70 bucks and the part is around 30 bucks. Good luck. Bright side is once you get it replaced it's like having a brand new dryer again.

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.
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.
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.
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.
One of the most common misconception's about dryers that are heating but taking way too long to dry is, oh no my dryer is broke, or something is wrong with my element. This may sometimes be true in a sense, but usually not. A dryer depends on proper air flow to expel the warm, moist air from your clothes to the outside of your home. Most dryer exhaust problems are not at the dryer but from the wall to the outside. The best and quickest and most fun way is to use an electric leaf blower to clear every thing in the exhaust line out, even water and critters that may find there way in. An inexpensive leaf blower from any major chain,Walmart, Kmart, Lowes or Home Depot will usually have fairly inexpensive ones. Pull the dryer form the wall and disconnect the exhaust from the wall vent. Place the end of the blower inside the vent and turn it to the high setting. Now take an extension cord that is not plugged into the wall yet and connect to the blower. Push the dryer back against the blower so it will hold the blower in place. Now that you are set plug the other end into the electrical outlet and let it run for about 10 minutes. Go to the outside where the exhaust exits your home and watch all the stuff fly. The blower is blowing approx. 230 mph winds thru your entire exhaust which will also help clean the walls also of lint and debris build up. Do this once a year and you will save problems for your dryer, the life of the dryer and most important service problems that end up costing much more than the blower and 10 minutes of your time. Good luck and thank you for reading and by the way, kids will love watching this too.
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.
Your heating element is good. It should read between 9 to 13 ohms. If the heating circuits are working, then you don't have a problem with the heating circuits. The numbe ron cause of drye heat related problems, or longer dry times, is poorly installed, or clogged ventilation. A simple test to try is to remove the exhaust vent hose from the back of the dryer and attempt to dry a load of clothes as you normally would. The air escaping the exhaust should be forceful and warm (about 140 degrees).
If the air flow is normal, and your clothes dry normally, the problem is with your exhaust ducting from the point where it leaves your dryer to where it exits your home. I would recommend you inspect the entire length of your exhaust ventliation to make sure it is free of kinks or clogs if this is the case.
If the air flow is weak, then the problem is INTERNAL to the dryer. The most common source of the problem is a clog in the blower fan housing preventing air to flow properly. Remove the blower fan housing cover and clean as necessary. Make sure the blower fan can turn unobstructed.
Let me know if you still have problems. I hope this helps you.
Ok, check the exhaust hose for obstructions. make sure the blower assembly is not clogged and, the hose is clear of any debris. the exhaust hose should blow out hot air forcefully. if the force of the air isn't blowing hard, it will not create a suitable drying environment for the element. this poor ventilation will also damage the heating element or burner Assembly.
Now, if there is sufficient air flow out of the exhaust hose, this will confirm control failure. replace the dryness sensor and control board in this case.
Here's a quick way to test for clogs. take the hose of the backside of the dryer then, start the cycle. if the drum sorts to become hot after a few minutes with the exhaust hose removed form theback of the unit, this will confirm a major block in the hose or blower assembly.
How warm is "warm"? If the clothes are warm to hot after 15 minutes of running but not gettign dry, you do not have a heating element problem. Sounds like you still have an air flow problem. Does the heating element cycle often? You may have lint clogged at he entrance to the blower. This would be out of sight from the exhaust. Try removing the exhuast hose and running it in air-only and feel the amount of air leaving. It should feel like a lot of air coming out. If not, you will need to check the condition of the blower. I had this same issue and ended up pulling the blower cover off and pulled out a very large amount of lint..it was almost completely clogged. Afterwards it drys really fast! Good-Luck.
PS If you do not feel comfortable accessing the blower, you should have a professional do it for you.
try drying load with vent tube disconnected may get warm and dusty but if works ok recheck vent completely also be sure vent is not being flattened when dryer is pushed back to wall also remove lower panel(clips along top edge each corner about 3-4 inches in)remove blower housing 2-3 screws and clean housing
Your problem may be related to a few things.. Depending on the age and use of your dryer, your heating element may be on its way out ( meaning that the element itself is eroding to a point of it not getting hot enough and will eventually open and need replacement) but.. you could have other issues too that affect the dry time.. You need to verify that your exhaust system is free from lint and is NOT restricting air flow out. You could have something in the blower itself that restricts air flow. Those are the basic components associated with your system dry process. If I were there, the very first thing I would check is the exhaust path out of the dryer ( including the end diverter to make sure that isn't restricting flow) Since yours is an electric dryer, you could do a simple test indoors by detaching the exhaust line and running the dryer inside for a short time.. The byproduct of electric dryers isn't as dangerous as a gas system so its ok to run it that way to check the flow coming out of the dryer,... Chances are one of the things I mentioned will solve your problem.. I'll keep an eye out for your feedback.. Hope this helps you
