Hi,
On electric dryers the problem can be caused by many different things that can go bad...and often it is a combination of things that go bad and cause problems.

The heating element can go bad but it very often does not. It is controlled by a thermostat... this often goes bad and then it caused the high limit to cut out the heat... this burns that out... so if the thermostat is bad then you also need to replace the high limit...

On many newer dryers there are sensors that also can go bad...if they are telling the dryer that it is already hot inside then the heat will not come on...they can be checked with an OHM meter...
Like wise if the sensor says it is too cool inside then the heat stays on till it trips the high limit...

Of course if your dryer was all plugged up with lint then maybe it just tripped the high limit and that is all that you need replaced...

So you can see that the best buddy of the troubleshooter is the OHM meter to check through the circuits and see why the dryer is not heating...there are many possibilities...

Dryer Takes Too Long to Dry


This advice is for problems with a dryer that runs and heats, but takes entirely too long to dry.

MOST dryer heat related problems are due to poor ventilation. As your clothes dry, warm moist air is exhausted out the dryer exhaust vent ducting. If you have any kinks, excessive bends, sags, or excessively long ducting runs, this can create choke points for lint to accumulate. Once the lint accumulates, it begins to collect moisture. As it collects moisture, it will act as a sponge and collect more lint until the dryer becomes completely clogged. Left in a clogged state, the dryer begins to overheat and dries less efficiently. You may notice longer dry times or an excessively hot dryer. Eventually the dryer heating circuits will fail which will require the replacement of failed components ($). This can also become a fire hazard if the lint becomes so backed up that it begins to collect on, or near, the heating element.

If you have not checked the dryer ventilation any time recently, now may be a good time to do so. I recommend checking it about once per season to ensure it is not obstructed. Make sure you are also using the SEMI-RIGID METAL type ducting. It resists crushing, kinking, resists heat better, and resists rodent infestation.

NOTE: If you are using plactic ducting, get rid of it. It collapses easy, rips and mice will chew right through it. Mice are notorious for building nests inside dryers. Give them a warm place with bedding material and they will make it a home.

Make sure the exhaust vent is at least 12 inches off the ground. This will deter mice and others pests (like snakes or birds) from entering the dryer exhaust from the outside. If you place a cover on the vent, make sure it is of the louvered variety. Do not use screens. They will collect lint and clog easily. Keep in mind, along with cleaning your lint trap after each load, you need to check the outside vent periodically to ensure it is not obstructed.

An easy test to determine if you have an exhaust problem is to remove the dryer vent hose from the back of the dryer. Turn the dryer on and attempt to dry a load of clothes as you normally would. The air leaving the back of the dryer should be forceful and warm (about 140 degrees). If the air flow is weak, you need to check the dryer interior. In particular, the blower fan housing. If the air flow is normal, and your clothes dry as they should, reattach the hose and run the dryer again. This time, check the exhaust vent where it exits your home. Again, the air flow should be forceful and warm. If not, you have a clog somewhere in the ventilation ducting which will require cleaning.

Check the ENTIRE run of the exhaust ducting. Make sure it is not kinked or crushed anywhere which can cut off air flow. Exhaust vent ducting that runs through attics and under crawl spaces are the worst. In an attic, air flow is forced in an upward direction in which gravity will always win. Lint will accumulate in the tubing and cause the dryer to work less effficiently. You will need to remove the dryer and clean the ducting periodically. Crawl spaces have similiar problems. If installed properly, the ducting should be suspended from the joists and not lying on the ground. However, over time lint can accumulate and cause sags. These areas will accumulate lint and eventually choke off the airflow. Again, it is recommended that you clean the ducting thoroughly each season. Leaving the ducting on the ground isn't the answer either as this gives ready access for rodents to chew through it.

In addition, many home owners unknowingly will push the dryer against the wall and crush the hose behind it. This will also clog the vent and make the dryer inefficient. Leave about a 1 foot space behind the dryer for proper ventilation and ensure the vent hose does not get crushed. Semi-rigid hose will prevent this from happening.

The general rule of thumb when it comes to dryer exhaust ventilation is the SHORTER and STRAIGHTER the run, the better. The longer the distance and the addition of more bends creates resistance and makes a dryer less efficient.

IMPORTANT: Exhausting a dryer freely into your home WITHOUT ducting (i.e., into an attic, crawl spce, or in a laundry room) is NOT recommended either. Dryer vent exhaust contains moisture. This added moisture, coupled with the warm air from the heating circuits will add humidity to your home and creates a breeding ground for mold and mildew. DO NOT run an unvented dryer in your home like this. It can become a health concern.

If you have any questions, please let me know. I have seen these problems many times. I hope this information is helpful.

Lint is getting passed the filter into the exhaust duct, even though the filter is always cleaned out. The lint accumulates in the lint exhaust pipe that runs to the back of the machine, and then into the...


Some lint will always get by the lint screen on ANY dryer. None of these screens are perfect and, YES, this is normal. This is why a routine inspection of the dryer exhaust ducting and internal cabinet are recommended about once per season to ensure the dryer remains running efficiently.

However, there are some things to consider when it comes to dryer ducting installation. The following link explains:

http://www.fixya.com/support/r3574332-dryer_ducting_installation_advice

Most excessive lint problems are a result of improperly installed dryer exhaust vent ducting. An excessively long run causes more resistance on the blower motor which will reduce its ability to sufficiently push all the lint out of the exhaust. Each bend in the run also creates choke points where lint can potentially accumulate.

The following link can give you some additional pointers on dryer heating efficiency:

http://www.fixya.com/support/r3578821-dryer_takes_too_long_to_dry

You may or may not be experiencing poor efficiency, but if you are getting excessive lint build up, it will eventually lead to longer dry times and a dryer that will actually overheat to the point of failure. Excessive lint build up is also a fire hazard.

You will experience this problem with ANY dryer as the performance of the best dryer will alway depend upon how well it is installed. This is not to imply that you have done a poor job in installing your appliance. I'm providing this information to give you some things to consider. Most consumers are not aware of the fact that they still need to perform routine maintenance on their appliances to make sure they run efficiently and problem free.

If you have any questions, please post back and let me know, I hope this information is helpful to you.

Slow to dry


Hi!!

Have you cleaned the filter and the exhaust duct??

Lint plugs therm up, the heat sensor shuts off heating element thinking it is hot enough. Result: Clothes not getting dry.

Unplug duct and clean it, also clean the exahust passage of dryer. (where duct hooks to dryer)

I have a Kenmore Elite dryer Model:110.C60952990 almost no heat.


Before assuming you may have a component failure, do a little routine inspection of the dryer and exhaust vent ducting.

If your dryer performance has been failing (i.e., clothes taking longer to dry), it may be because the exhaust ventilation ducting is clogged. If you can't remember the last time the exhaust vent was cleaned, or if it has never been done, this can contribute to dryer performance problems. All dryers need proper air flow in order to dry properly. If the ducting becomes clogged, the heating circuits will actually overheat, causing poor drying results and eventual failure. This usually results in the Thermal Cut-Out (TCO) blowing or the Heating Element failing or BOTH. When these components fail, they must be replaced.

There is no lint screen that catches ALL the dryer lint. Some lint will always get exhausted with the moisture from your clothing. If the exhaust vent is kinked or has excessive bends that create choke points, lint will accumulate in these points. Once the lint starts to accumulate, the moisture from your clothes starts to collect in it, and more lint get trapped. This eventually creates a clog. The Rule of Thumb: The SHORTER and STRAIGHTER the exhaust ventilation ducting, the BETTER.

A simple test to determine if you have a clog somewhere is to remove the dryer hose from the back of the dryer and attempt to dry a load of clothes as you normally would. The air escaping the back of the dryer should be forceful and warm (about 140 degrees). If the air flow is normal and the clothes dry as they should, then you need to inspect the ducting thoroughly from where it leaves the dryer to where it exits your home. It should be clear with no kinks or clogs.

If your vent line runs under a crawl space make sure it is suspended above the ground and has no sags where lint could collect.

If your exhaust vent runs to an attic, this is a poor design that gravity will always win because of the resistance the blower fan meets trying to push the exhaust up the wall. The lint will eventually collect in the ducting going up the wall and have to cleaned out from time to time.

Also, make sure you don't crush the dryer hose behind the dryer when you push it up against the wall. You should always leave plenty of space behind a dryer to prevent this from happening.

Rodents and birds are anotehr cause of dryer problems. If they have access to the outside exhaust vents, birds will build nests in them and mice love a warm place with plenty of bedding material (lint makes a nice nest). Make sure the exhaust vent is at least a foot from the ground and use a louver type cover to keep pests outside. Do not use a screen. It can resist air flow and clog.

In addition, you should be using semi-rigid metal type ducting that resists kinking, crushing and rodent infestation.

If the air flow is weak, then you need to inspect the dryer INTERIOR to see if the air blower is working properly and is not clogged. It is important to keep a dryer checked routinely. Failue to do so can lead to component failures and is a potential fire hazard.

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

The back of my dryer is getting very hot and actually tripped the breaker, also clothes taking forever to dry


Pull the exhaust vent off and check for obstructions, if there's no flow, all the heat is going to build up and also block any lint from escaping out the vent as well.
This can be a fire hazard as well. You may also need to open the dryer and clean out all the lint build up.
When you pull the pull flex hose off the back (the 4"diameter one) check in the back of the machine in the pipe and also in the flex tube. You may have to explore a little in the exhaust line to find the blockage...sounds like this is your issue...

Dryer problem


check input voltage make sure you have 240 volts red to black and 120 red or black to white. then check heating element. and hi temp cutoff. On Frigidaire built machines (includes some GEs) a temp thermistor on exhaust duct at front of machine is a common problem. 50ohms is normal- less causes problems

Whirlpool Model LE7010XSNO. No Heat After Lint Cleaned Out


Those are likely possibilities. Also check the wiring for disconnected or burned terminals especially in areas that get hot. The element comes out easily to visually check it for breaks. If that's OK I'd look at the safety thermostat.
