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.

SOURCE: Electric Clothes Dryer Problem

if the dryer worked fine before with the element not staying on when you open the door, etc, then what you have done is a very common mistake to make, you must have dislodged a wire off, or maybe placed one back in the wrong place, its a very easy error to make, which is why when removing parts for repair on any appliance you must make very detailed notes, better still take digital photographs with a digital camera double check any wires etc, don't worry i am a retired appliance engineer and even we can make this mistake

SOURCE: dryer spins but no heat

Did you check the power coard where it connects to the dryer? Start at the source. Make sure that you have at least 110v on each line. The dryer will tumble on 110v but requires 220v to heat. If you have 220v then check the t-stat and thermal cut-out on the blower. Check all wires for loose or burnt terminals. If all that is good it may be a bad motor or timer/control. I'm happy that you have a meter.
Good luck.

No heat LG Dle2516w dryer


Your heating coil is broken. IMHO. If it was working you would not get a voltage reading. Element is shorted to frame. Power flows through both wires the element is connected to. If the circuit is not interrupted their is no reading on a single line. You have an open heater element. Disconnect power from the machine. Remove the wires from the element and check continuity between the 2 terminals (no reading element no good). Check continuity between each terminal to chassis (should not get an ohms reading) If you get an ohms reading the element is shorted to the heater chamber. Sometimes an element will droop and touch when heated. You can sometimes free up the welded wire and reposition it. that is rare though.

Dryer quit heating no power to element what is wrong?


The problem is most likely the thermal cut-off and the high-limit thermostat. The thermal cut-off blows when the high-limit thermostat fails and since these parts are wired in series with the heating element, power to the heating element is therefore terminated. Check the continuity of the thermal cut-off and if it reads open, replace it along with the high-limit thermostat.

You can bypass the thermal cut-off and the high-limit thermostat for troubleshooting purposes. Join together the wires of each part and insulate it properly then reconnect power. The two components indeed need to be replaced if the dryer heats up. If not and still no power to the heating element, check the continuity of the heating circuit. Check the continuity/resistance of the heating element if there's power to its terminals but doesn't heat. Replace the heating element if it reads open.

Let us know if you need further advice. Just indicate the exact model number of the dryer for accurate troubleshooting tips.

Heating element replaced. Worked one load and back or dryer seemed very hot. Turned off and later ran on low. Next load no heat.


Hi.

There is either a problem with the thermostats that turn off the heating element, or the heating element is plugged (elements has contact to ground and stays always on).

Heating element and thermostats are tested reading Ohms with a multimeter set at Rx1. If the circuit is open (Ohms stay infinite), then the part is defective.

If the machine overheated, then the element may be gone again. Test reading Ohms.

Also replace the thermostats (there should be two or three of them), unless the element had a contact, the most common cause for overheating is a shorted thermostat.

No heat, but dryer turns.


There are three common causes of a dryer not heating. First is a busted heating element. Second, the thermal cut-off has blown. Third, the high limit thermostat is not working.

Disconnect power to the machine and remove the screws at the bottom of the lower front access panel (toe panel) holding it in place. Pull the panel down and off the cabinet. You now have access to the heating circuit.

Remove the heater shield by removing its mounting screw and pulling it off the heater housing.

The heater terminal block is located at the left opening of the heater housing. Disconnect the wire from one of the heater terminals and measure the resistance of the heating element using an ohmmeter set to X1. The resistance should read 7.8 -11.8 ohms. Replace the heating element if the resistance reads open.

Disconnect the wires from the terminals of the heating element and remove the screw securing it to the heater housing. Slide the busted heating element out of the housing and install the new heating element. Secure it with the screw and put the terminal block in place. Connect the heater wires and reinstall the heater shield.

Slide the lower front access panel up into the cabinet and secure it with the screws.

Kenmore d433 not heating


I you are reading a voltage across the element I would expect that meant that the element had going open circuit. dryer elements should have continuity through them and thus you shouldn't read a potential voltage across them. Especially while it's off.

If the heating element is getting supplied voltage, even when it's off, that may have cause the element to cook itself.

Kenmore Dryer runs with no heat


An open circuit does mean the element is bad and will need to be replaced.
Just in case though, make sure your meter is working properly by touching the leads together. You should get a reading.
Good luck!

Heating element continuity?


Unplug the dryer from the wall. There are 2 wires connecting power at the heating element. Take one of these wires off, doesn't matter which one, but take at least one of the 2 off. Then put your meter probes across the terminal of the heating element where you took the 1 wire off and the other terminal of the heating element that still has a wire on it. Your meter will pretty much read full continuity if good, no reading at all if bad. Also check from one of these terminals of the element with one meter probe going to the metal frame of the unit. You should get no reading. If you do the element is shorted and would have likely tripped your house breaker.

Better to test a heating element for voltage with your meter like I described to you in your other question. I've seen heating elements read good when just doing a continuity test, however once voltage is applied and they start to heat they can expand and open up, thus not work, even though testing good when doing just a continuity test. Not always, but sometimes, it does happen enough to note to you.

Dryer heating element(s) are inconsistent


there is only 1 element. were you taking these readings with the wires on them?
the other 2 were thermostats.was there lots of lint?
sounds like you may have bad thermostat.

Blowing cold air


There is not a reset button on an electric dryer that I know of. If a dryer is blowing air at all, that tells me that the blower assembly and drum motor are working. If you have not heat it is generally caused one of the following:

1. Bad thermal cut-out - located near the heating element housing. Should read a SHORT (0 ohms on an ohm meter) if good. If bad, it is generally a good idea to replace the TCO along with the Hi-Limit Thermostat (mounted right next the TCO in most cases) because the TCO is designed to protect the thermostat and heating element. If the TCO fails, it is likely that the thermostat could also be damaged.

2. Hi-Limit Thermostat failure - located near the heating element housing. The thermostat opens when the internal heat reaches about 157 degrees (on most dryers). This helps regulate the dryer temperature and helps protect the heating element. If it reads a constant OPEN (infinity reading on an ohm meter), replace it along with the TCO (as mentioned above).

3. Bad Heating Element - located under the drum on some dryer models and in the rear on others. The element should read about 9-11 ohms if good. If they go bad, the element will generally burns itself OPEN.

I will need you model number (located near the dryer door opening) in order to give you better advice on how to access the inside of the dryer. Post back with comments and let me know. I hope you find this helpful.

PS I hope I didn't insult your intelligence, but some people are little more saavy than others, so I try to explain things in the simplest of terms.
