If your dryer runs, but does NOT heat, the following two links explain how to troubleshoot an ELECTRIC dryer with a no heat problem:

First, begin by unplugging the dryer and verifying the voltage at the wall receptacle. You should read 220-240VAC across the two Hot terminals (left and right slots). If the voltage is incorrect, check to make sure you don't have a breaker tripped. Some homes use 2 separate 120VAC breakers to provide power to the receptacle vice using one 240VAC breaker.

If the voltage IS correct, leave the dryer unplugged and remove the cover plate on the terminal block in the back of the dryer (this is where the power cord is installed). Plug the dryer back in and take a voltage reading across the two hot (RED and BLACK) wires at the terminal block. You should read 220-240VAC. If the voltage is good, you have an internal heating problem. If the voltage is bad at the terminal block, but good at the receptacle, you have a bad power cord.

NOTE: If the wires at the terminal block are not color coded, the outer two wires (left and right) are the hot leads. The center conductor is neutral or ground.

The reason a dryer will still run if the input voltage is incorrect, is because the drive motor only uses a portion of the 220 service. The motor runs off 110-120VAC, while the heating circuits require 220-240VAC. So, if you are missing 1/2 your input voltage due to a tripped breaker or bad power cord, your dryer may exhibit these symptoms.

If you determine the problem to be internal, the heating circuits will either be located in the rear of the dryer on the right hand, or under the dryer drum on the right hand side. Usually, an easy way to determine is by the location of the lint screen filter. If the filter is on top of the dryer, the heating circuits are in the back of the dryer. If the lint screen is in the door, the heating circuits are located under the dryer drum.

The Heating Element is located inside a heater box. The Thermal Cut-Out (TCO) will be located on the outside of the heater box on the end opposite the heating element terminals. The Hi-Limit Thermostat will be located adjacent to the heating element terminals.

If either the TCO or Hi-Limit Thermostat are determined to be bad, replace BOTH components at the same time. That is why these components are commonly sold as a set. Failure to do so may result in premature failure of any parts you replace.

Replacement parts (if required) can be found at the following websites:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com

The average cost of these components varies, so shop and compare. The first three websites I listed have helpful exploded view parts diagrams that can help you locate and properly identify the parts you need. The heating components are usually listed under the "Bulkhead" section.

NOTE: In many cases the problem is not the heating element. The heating element has protection devices that are designed to regulate the heat temperatures. If the dryer overheats the Thermal Cut-Out (TCO) typically will blow BEFORE the heating element. The replacement kit is much cheaper than purchasing a new heating element that may or may not be the problem.

Read through the information I provided and, if you have any questions, please post back and let me know. I hope you find this information is helpful.

Dryer lost heat


This may be a heating element issue.
If you want to do a few things before calling someone, you would want to start by making sure all of your dryer settings are set correctly. Some dryers have "air" settings or "delicates" settings. These settings are going to be very low heat so the clothes are not ruined.

Also make sure that the lint screen has been cleaned each and every time you have started a new load. If not, you can UNPLUG the dryer, pull the dryer out and with some simple tools, take the back off and vacuum what you can get to. If it's very dirty you'll want to call a professional. You'll need it cleaned and your problem diagnosed. If cleaning the lint screen is not something you have done on a regular basis, then please start. This could be a fire hazard if it is not cleaned regularly.

Another thing to check is your vent or vent hose. Depending on how your set up is, if your hose is crimped behind the dryer and the heat can't escape, the clothes will not be able to dry. This would only be something if you have some heat but clothes are not drying. Also, sometimes due to the age of the hose, previous use, not cleaning the lint screen, etc, the venting from the house to the outside could be clogged. Again, there will be some heat, but the clothes will seem to take forever to dry.

Good luck.

Dryers do what they are designed to do, Dry things. In the process everything inside the drying cylinder makes dust and airborne particulates called Lint. The Biggest bane for dryers is Lint accumulation. Clean the Lint filter screen. If it detaches from the dryer housing with screws remove them. Clean out what you see if you have a wet vacuum with a small hose carefully push this down into the opening and vacuum it ou. Another thing pull your dryer out from the wall disconnect the power and remove the vent hose. Vacuum inside the opening in the back of the dryer. You would be surprised how much lint accummulates here. Lastly check your vent hose for lint accumulation or blockage. If you find it blocked, disconnect the hose from the vent going outside and clean it all out with a vacuum . Put it all back together and run a load of clothes if you dont see a marked improvement in circulation and drying time, then either the blower fan is n't working properly or you have a burned out thermostat. If you have heat flowing turn it up to max heat and see how hot it really gets if on opening the dryer you feel extreme heat then it is either working right or the thermostat is not shutting off at the high limit. the Thermostat is a piece of Bimetallic metal that is extremely sensitive to certain temperatures. When they reach the preset heat limit they shut off allowing the heating elements not to burn out. A good investment is to keep dryer maintenance at regular intervals. They sell dryer cleaning brushes and Vacuum hose attachments for getting into the deep crevasses and nether regions of your dryer. Good luck and happy drying

My gas dryer runs forever without making any heat. The timer doesnt advance at all. The air flows great just no heat. On a VERY rare ocassion there is a little heat but hardly ever.


Hi there,

Well if your dryer tumbles, but there is no heat then you may please check out the following -
1. First of all you can check out for proper air flow - Check the vent for proper air flow by placing your hand over the exterior vent while the dryer is running. You should feel a strong flow of air. If not then check the lint trap. It is located either on top of the dryer or possibly just inside the door. Remove any lint that has built up in the lint trap. Cleaning the lint trap should be done regularly, even as often as after every load. Do not operate the dryer without a lint trap in place.
2. Secondly you can check out the Ignitor - gas dryer blows air through a burner assembly to heat the air. The burner assembly consists essentially of a gas valve, ignitor and a flame sensor. If any part of the burner assembly malfunctions, the result will be low or no heat and slow drying of the clothes. Post comments for further help or information.....
Good Luck!!

HI, Check the following to address this issue further.


1. Venting
Make sure the dryer vent hose, as well as the rest of the vent duct, is not clogged.

Unless regular maintenance is performed, chances are there is a lot of lint accumulated inside the dryer. This might affect the drying time and could be a fire hazard. Make sure to have your dryer cleaned regularly. Because this might involve taking most of the dryer apart, it is recommended to have a qualified appliance repairman perform this task. The blower housing should be disassembled, and cleaned in this case.

2. Thermostat(Secondary Cause)- Highly unlikely in your case, but possible
There are a couple of cycling thermostats inside the dryer. If one of them breaks down, it might affect the dryer's performance. Replace the defective thermostat. These thermostats are located in the dryer vent duct and sometimes mounted on the blower assembly as well.

3. Heating element
A heating element might only be partially burned out, in which case it would still work but will take longer time to dry the clothes. Replace the element if found defective.

Dryer is spinning and warming up but it's not drying


Exhaust full of lint. Vacuum into dryer exhaust as far as you can, Then clean out complete vent from dryer to outside. Any lint will catch moisture and clothes will not dry.
