Question about LG DLG3788W Gas Dryer

Dryer doesn't heat

I've had this dryer for a little over 3 yrs. In the last 3 months I've had 2 different thermostats/fuses replaces. After the last repair I was able to dry one load of laundry and then I had no heat again.

Called the repair man again and this time he tells me its a problem with the vent. Does this sound possible. Why after three years would I start to have trouble with the vent?

I'll take a stab at this and hope I can help ! It could very well be your vent .. After three years of venting gases from drying, it is possible and quite probable that your vent may be restricting airflow from lint/other byproducts of drying. A quick check might be to run a separate vent ( temporary ) in place of your existing one to see if that solves the problem. I assume your dryer is Gas and not electric from the G in the DLG id. If it was electric, then you could vent it in the room for a quick check but since it is gas, I would discourage that. Check the flapper on the end of your vent too to make sure it is opening up when you dry clothes.. the screens on them prevent birds etc from going inside your duct work but they also make a nice place for lint to build up and restrict the air flow. Hope that helps !

Mine was doing the same thing. if i take the vent completely off the dryer it works fine. As soon i reconnect it shuts the gas off. In my case it is obviously the vent duct. I'm replacing today.

My whirlpool dryer comes on and runs good but it wont get hot can you tell me whats the problem


Hello there and welcome to fixya there are several things that could make this dryer not heat up
Here are the most common things

Thermal Fuse

If the dryer doesn\'t heat, but the drum
turns, check the thermal fuse(s). The thermal fuse protects the dryer
from overheating and helps to prevent fires. If the thermal fuse is
blown, it will have to be replaced.




Enter your model number to see parts for your dryer.

Help me find my model number


Gas Valve Solenoid

The gas valve has two or more electric
solenoids which open the valve to let the gas flow into the burner
assembly. If the dryer doesn\'t heat one or more of the solenoids may be
defective. If the igniter glows for 90 seconds but the burner flame
doesn\'t light, replace these coils as a set.


Dryer Igniter


If the dryer doesn\'t heat, the igniter might
be burned out. Check the igniter for continuity with an ohm meter. Dryer
igniters burn out over time, similar to a light bulb.


Heating Element

The heating element on an electric dryer can
burn out over time. If the dryer doesn\'t heat, the element should be
checked for continuity. The heating element cannot be repaired and must
be replaced if defective.


Heating Element Assembly

the heating element assembly on an electric
dryer can burn out over time. If the dryer doesn\'t heat, the element
assembly should be checked for continuity. The heating element assembly
cannot be repaired and must be replaced if defective.

Flame Sensor



Gas dryers have a flame sensor to detect the
heat given off by the flame. If the dryer doesn\'t heat, the flame sensor
might be defective. Check the flame sensor for continuity. This is not
as common as a burned out igniter or thermal fuse.


High Limit Thermostat


Although not common, if the dryer doesn\'t
heat the high limit thermostat can be defective. It can be checked for
continuity. If the thermostat is "open" the dryer doesn\'t heat.


Cycling Thermostat




The cycling thermostat regulates the
temperature of the air in the dryer. If the dryer doesn\'t heat it may be
caused by a defective cycling thermostat. This is not common.


Main Control Board

The main control board is normally not at
fault when the dryer doesn\'t heat. Check all of the other components in
this troubleshooting guide before replacing the main control board. The
main control board cannot be tested easily and must be replaced if it is
defective.


Timer
The timer is normally not at fault if the
dryer doesn\'t heat. In many situations where timers are replaced they
end up being returned. Check all of the more common components in this
troubleshooting guide before replacing the timer

If you have fuses on your electric panel it normally uses 2 fuses, 1 for electric power 1 for heat. The same may be true on the circuit board panel check this to eliminate this possibility

EWe have replaced 2 thermal fuses on my inglis dryer in the past two months. It overheats and blows them.


is the blower wheel turning freely and all the time,if not replace it,they do strip out on the motor shaft,if the air is surging then if its not the wheel,then it still has to have a restriction somewhere else

HI My Beko is just over 12 months old. Recently I have noticed that the washing isn't drying, initially I assumed it was stopping prematurely so I tried running different dry cycles 2 or 3 times...


Hi jo young72...

Here are a few things to check:
ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Check to make sure you are getting full 220 Volt power to the dryer, if you are then:
Check your Wiring
Often the main wiring connection from the house, at the dryer, burns and the connection breaks. If this has happened to your dryer, you need to replace the power cord and the terminal block inside the dryer to which the wire is attached.
Check the Door Switch
If the door switch or the door-switch actuator is defective, the dryer won't work and you need to replace the failed component. The switch is inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. Check for continuity you should have none with door open, and should have a reading when closed. If not replace the door switch.
Check to make sure you heating problem is not a lint build up in the discharge hose or the dryer,as this condition can cause heater/thermistor problems such as overheating of the heating coil leading to failure of the coil and burnout of the thermostat/thermistor due to overheat.
Remove the back/or front just under the door of the machine and try to locate the air duct going from the blower to the drum. Normally inside/outside the air duct you will find the heating coil and the thermostats/thermistors. 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/thermal fuse one at a time by removing the two wires and taping them together with electrical tape.
If the coil heats up then replace the thermostat/thermistor/thermal fuse as it is faulty.
If you have an ohm meter then you can test the thermostat/thermistor/thermal fuse,
then you do not have to tape the wires together as described above.
To test your thermostat/thermistor/thermal fuse remove the wires from the thermostat/thermistor/thermal fuse and check for continuity, if you DO NOT have continuity then replace the thermostat/thermistor/thermal fuse.
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST AS THIS COULD CAUSE A FIRE BECAUSE YOU HAVE REMOVED THE SAFETY.
Check your blower wheel to make sure it is secure to the shaft and not plugged with lint,socks,etc.
If the thermal fuse overheats the dryer will not operate. It's located on the blower housing. It cannot be reset.
You can test it with an Ohm meter or continuity checker, remove both wires from the thermal fuse and put the test probes to each of the ends of the thermal fuse, if no continuity then replace the thermal fuse.
A vent clogged with lint can cause it to overheat.
Right after replacing a dryer element, always run the dryer on 'air fluff' / 'no heat', and go outside to verify there's plenty of air coming out your vent system.
If the vent's clogged, that new element can burn out very quickly.

If I remember correctly, this model has a switch on the motor which activates both legs
of the 220 to allow the heating element to come on. There is a wiring diagram under the

Makecertain that your wiring is not exposed to anything. Be sure to turn the power off to the dryerand check the outlet. Also check to seeif your dryer cord is connected to the dryer right. Usually the outer prongs on the dryer are thehot and in the inner one is the ground.

Dryer doesn't get hot enough to dry clothes


Hi


Thanks for using FixYa. The first thing that should be checked is the Thermal fuse which is mounted to the exhaust duct inside the back cover. If this fuse goes bad the dryer will not heat and you’ll have to replace it as it cannot be repaired. If this I fine then you’ll need to check the thermostat, igniter and coils. Also as its only 3 months old so it is recommended to use the warranty to avoid any further issues. Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee
