SOURCE: Dryer Heats - Drum Turns - Clothes Don't Dry - Dryer Seems To Over Heat

Before ripping into the dryer, with the dryer running, check the vent outside. There should be a rather strong air flow. I'll bet you have little or maybe no air flow. Check behind the dryer to make sure you don't have squished flex duct. If you have flex pipe, try running the dryer for a few minutes with the dryer pulled out into the room to stretch the vent out, and check outside airflow again. Try to eliminate all or as much of the flex stuff as you can, replacing it with aluminum dryer vent pipe. (tape joints with foil duct tape) Clean out remaining dryer vent. (there are special brushes you can buy to clean out vents, but they really only work on ridgid pipe.)

SOURCE: whirlpool gold electric dryer.

If the dryer turns on, drum spins, but you have no heat, any of the following components could be bad:

Heating Element
Thermal Cut-Out
Hi-Limit Thermostat

All these components COMBINED, should cost less than $100. If you fix it yourself, you will avoid the additional cost for labor.


If the dryer isn't blowing ANY air at all, but the drum still turns, you may have a bad blower fan assembly inside the dryer. Or, the blower fan assembly may be clogged.

If your dryer performance has been failing (i.e., clothes taking longer to dry), it may be for a reason. You need to ask yourself when the last time you cleaned the dryer ventilation. If you can't remember, or if it has never been done, this can contribute to the dryer failing. All dryers need proper air flow in order to dry properly. If the ducting becomes clogged, the heating circuits will actually overheat and eventually fail. 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. Remove the dryer hose from the back of the dryer and inspect it 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. RULE OF THUMB: The SHORTER and STRAIGHTER the vent duct, the BETTER. After you inspect the vent ducting, turn the dryer on and make sure you have forceful air flow coming form the dryer. This will prove that your blower fan is working properly or not. Since you stated that your dryer is not currently heating, the air will be cold, but you should still have some force behind it. If the air flow is weak, you need to clean the duct work INSIDE the dryer. It is important to keep a dryer checked routinely. I recommend once per season (that's 4 times per year). Dryers are the cause of many house fires. These fires are due to lint accumulations inside the unit catching on fire. A little preventive maintenance can prevent significant problems in the future.
Getting to the heating circuit to determine if the components are good or bad is the next step. If your dryer has the lint screen on the top of the unit, you will need to remove the back panel of the dryer to expose the heating circuits. If the dryer has the lint screen in the door, you will need to remove the lower kick panel under the door by using a putty knife to release the retaining clips. They will be located along the seam in the front about 2 inches in from each side. You have to remove the entire front panel on some models. This is accomplished by lifting the dryer top and removing the screws that hold the front panel in place.

NOTE: The heating circuit should be troubleshot with the dryer UNPLUGGED. Dangerous voltages are still present with the dryer turned off. Resistance readings are as follows:

Heating Element (located inside heater box) – remove the two RED leads from the ceramic terminals on the heating element and take a reading across the terminal points. It should read 9 - 13 ohms.

Thermal Cut-Out (TCO) (mounted to the heater box.) - unplug wires and take reading across connector tabs. Reading should be 0 ohms.

Hi-Limit Thermostat (mounted to the heater box, closest to the heating element leads) - unplug wires and take reading across connector tabs. Reading should be 0 ohms.

If any of the above readings are abnormal, replace the component. NOTE: If the TCO or Hi-Limit Thermostat is defective it is highly recommended by most manufacturers to replace BOTH components at the same time. They are often sold as a set.


I hope this information is helpful to you. Post back with comments if you have any further questions.

SOURCE: LG Dryer won't dry, no heat.

The heating coil is not too big of a problem to replace if you are mechanically inclined and have tools to do the job.
If you plan to try to repair the problem yourself, then the first thing you want to do is unplug the dryer from the electric.
Remove the back of the machine and try to locate the air tube going from the blower to the drum. Normally inside the air tube you will find the heating coil and the thermostats/thermistor.
Once you have located the heating coil, remove the two wires from it and check the coil with an ohm meter across the two terminals of the coil.
You should read continuity across the terminals, if not you will need to replace the coil as it is faulty.
If the heating coil is ok, then:
You can check the thermostat/thermistor by removing the two wires and taping them together with electrical tape.
If the coil heats up then replace the thermostat/thermistor.
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST. This could cause a fire, as you have removed the saftey of overheat from the machine.
Good Luck,
Hope this helps

Loud piercing noise when drying


It doesn't work at all dot_lineone.gif 1. No power to the dryer
Make sure there's power getting to the dryer. Check for a tripped circuit breaker or a blown fuse. Check the wall socket for power with a voltmeter or by plugging something else in. Sometimes the power cord disconnects or burns at the dryer, if this is the case, the wiring and the terminal block must be repaired or replaced.
2. Door switch / Door switch actuator lever
The dryer would not start with a broken door switch. Replace the door switch if found defective.
Most dryers have a door switch actuator lever - when you close a dryer door, it presses against the lever, which actuates the door switch. If the lever is broken, the switch would not activate and the dryer would not start. Replace the lever, if broken.
Note: Door switch actuator lever usually comes with the door switch assembly and it is recommended to get the whole assembly since there is almost no price difference between the door switch assembly and just the lever. Check your model for more details.There's no heat dot_lineone.gif 1. No power to the dryer
Make sure there's power getting to the dryer. Check for tripped circuit breakers or blown fuses. An electric dryer uses two circuit breakers or fuses, and if only one of two is tripped or blown, the dryer might still run but not heat. Sometimes the power cord disconnects or burns at the dryer, if this is the case, the wiring and the terminal block must be repaired or replaced.
2. Heating element
A burned out heating element will show no continuity when measured with a meter. Replace the element if found defective.
3. Thermal fuse
Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting. It takes to long to dry dot_lineone.gif Note: Normal drying time for a dryer is about 45 minutes (some may take up to an hour).
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.
2. Thermostat
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.
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.

Dried a load fine, next load tumbles wont dry. still cant get heat


Hi,

Make sure front of dryer is not blocked, air flow is needed to dry.Check that the lint filter and exhaust duct is clean.

Check the blown fuses and home’s circuit breaker tripped. Dryer use 2 household Fuses or a circuit breakers, If one is blown, the dryer may still operate but not heat. Alternatively, the dryer may heat, but it may not heat up as hot as it should. Replace the Fuses or reset the circuit breaker.


Another common cause of a dryer failing to heat is a faulty Heating Element. You will need to replace it.


Good Luck and have a nice day.

No heat


If there is no heat during drying cycle, it is usually either the heating element, or a thermal fuse.

See the following suggestions from repairclinic:

If your dryer doesn't heat, check these:

Heating element
Thermal fuse
Wiring

Heating element Often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. The heating element is simply a long coil of special wire. You can check it for continuity with an ohm meter. No continuity means the element is bad and you need to replace it--electric heating elements aren't repairable.

Thermal fuse On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel. The fuse--which is about an inch long--is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, you need to replace it. (You can't re-set it.)

Wiring A common problem is for the main wiring connection from the house, at the dryer, to burn and break its connection. Because the dryer can still tumble with partial power, the connection may be only partially defective. You may need to replace both the power cord to the dryer and the terminal block inside the dryer that the wire is attached to.
