Check the switch sometimes wires are disconnected at the post. Or check the wire mesh or the exhaust vent pipe sometime it is clogged and therefore not enough heat inside the drying chamber.

Sounds like your problem is with the heating coil.
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 a continuity 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.
Good Luck,
Hope this helps

Dryer works OK on timed dry but doesn't dry the clothes in Auto dry.


In some dryer's the control panel relies on a thermistor rather than a CYCLING thermostat to regulate the drum's air temperature by monitoring the component's resistance changes; resistance goes down as temperature increases and up when temperature decreases. Once the drum's air temperature reaches a certain level required to dry clothes, the control panel shuts off the heater. The panel will turn the heater on again and begin another heating cycle when the thermistor indicates that more heat is needed to keep the air temperature constant inside the drum 9 this is why in some cases the dryer will operate at lower cycles like gentle or low heat but not at higher settings?)

Lastly check your moister sensor. ( located inside the dryer door usually) Especially if machine seems to shut down early and clothes are still wet.
Test with a meter at room temperature and it should show continuity.
A failed moisture sensor will affect the dryer run time in the automatic moisture sensing cycle but it will not affect the heating of the dryer or the timed cycle. Which are reflected by the thermostats.

Run the dryer for 2-5 minutes. Check to see if it has heat inside. If not, you have an internal problem.
If heat is generated, check your dryer lint trap. It must be clean before every dry cycle to dry properly and efficently. If the trap is clean and heat is generated, check the tubes behind the dryer for disposing of the lint.

LG Dryer takes too long to dry clothes


Sure the outside vent is not clogged up? If so it will overheat and turn it self off and do a poor job of drying the clothes.

Also check and make sure that all of the heating elements are working properly.

We have a Kenmore 400 Series dryer. It heats up but our clothes is not getting dry. We have to cycle it twice to get our clothes dry on high heat. Any idea why it would take 2 cycles to dry?

This was the out vent of my dryer... If it gets this bad... open up the dryer housing and clean inside too. Also make sure the intake is free of lint.

Dryer takes 2 or 3 cycles to dry


A Whirlpool dryer either heats or doesn't heat . This problem is an indication of a blocked vent hose , from the rear of the dryer to the outside vent outlet . Try removing the vent hose from the back of the dryer and dry a load , to verify this problem . Wet lint inside the hose also means the air cannot escape to the outside .

My dryer takes 2 to 3 cycles to dry my clothes.


Check the following areas to combat this issue. in most cases, this will be a Venting issue.

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.

Dryer Gets Too Hot!


Could be the heat switch on the motor or a grounded heat element

Will not dry clothes fully. the machine heats fine but it takes two or more cycles to fully dry a little load. someone told me about a part that may need repaced around the lint trap.. Any ideas?


Your lint exhaust is blocking the heat flow.
Remove the vent from the rear of the dryer and run a timed cycle load for 40 minutes.
If laundry is dry, repair the outside vent.
If not dry,open the dryer cabinet and clean the inside lint and heat vent.
