LG DLEX5101W Dryer won't heat

There is a sensor at the bottom of the filter slot and it could be bad or plugged with lint. The whole service manual is here: http://www.manualslib.com/manual/974184/Lg-Dlex5101w.html?page=45#manual

It is going to show you the page with that sensor, but you can look at all the pages, I suggest page 23 for diagnostic tests.

another user's Q&A for the same issue try that or call may tag, they are supper helpful

Investigate these five areas if your dryer is not heating up:

Proper Voltage

If your dryer won't heat up, it's possible that it is not being supplied with the proper voltage. Here are three ways to make sure power is getting to your dryer: First, make sure your dryer is plugged in. Next, check the circuit breaker panel to make sure all the circuit breakers are in the correct positions. Finally, check to make sure no fuses in your fuse panel are blown. Any of these could explain why power is not getting to your dryer.

Heating Element

It is possible that your dryer isn't heating because its heating element is defective. Heating elements are irrepairable. If yours has ceased to function properly, you will have to replace it. Open your dryer's cabinet and locate the heating element so that you can test it.

• Find a heating element for your clothes dryer.

Thermal Fuse

Another possible cause for a dryer not heating up could be attributed to a faulty thermal fuse. Once a dryer's thermal fuse has blown, it is no longer of any use. If your dryer's fuse is blown, you will have to replace it. Open up your dryer's cabinet and locate its thermal fuse so that you can test it.

Thermostat

If any of your dryer's thermostats have become defective, they could be the reason that your dryer is not heating. Open up your dryer's cabinet and test each of your dryer's thermostats. If any are faulty, replace them.

see the causes, and proceed. God bless you

Timer motor

A defective timer motor could also cause your dryer to not heat up. Test your dryer's timer motor. If it is no longer functioning as it should, replace either the entire motor assembly, or just its motor.

Did you reset the circuit breaker located on the burner at the 7o'clock position.

Many times one pole of a double pole breaker may trip allowing the dryer to operate but with no heat. Go to the electric panel and reset the circuit breaker for the dryer. Also check to insure there is air flow at the vent a clogged vent willl prevent clothes from drying

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

Select the heat setting other than Air Fluff.

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.

Good Luck and have a nice day.

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

Hi, Make sure you check these to fix the problem.

• Check to see whether there's power getting to the dryer. Is it plugged in? Check for blown fuses or tripped circuit breakers--your dryer uses two fuses or circuit breakers. The dryer could tumble but not heat if only one of the two fuses is blown. If you have circuit breakers, one of the two circuit breakers can trip, even if the two for the dryer are connected.

• 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.

• 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.

Dear customer,
                We recommend you to do the following checks when your dryer isnt generating heat..

1. Check for proper air flow
   
2. Test the safety fuse
   
3. Test the thermostats
   
4. Test the centrifugal switch
   
5. Test the timer motor
   
6. Test the heating element.
   

Thank you.

it could be the thermostat it could be a burned heat element if electric verify gas or electric
