Lgq9858pw dryer. Clothes would come out damp and cold. I replaced 2 thermostats (?) in the rear of the unit, located on the heat shield. The clothes now come out warm, not hot, but still damp. Any ideas?

Are the clothes wet AND hot? If so - check the exhaust / vent hose for kinks or obstructions. That includes the cap / flap on the outside of the house.

If the clothes are wet AND cold, then the electric heating element isn't heating likely due to a broken or poor electrical connection, burned out heating element, defective thermostat, etc..

there is 3 things to check other than the element.
thermal fuse
cycling thermostat
high temp thermostat

Clogged Vent
If your dryer seems to run forever, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system.
Normally, this is what happens during an automatic cycle:
The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees.
When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.)
The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again.
This cycle continues until the clothes are dry. But...if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.
Heating Element
Your dryer's heating element may be partially burned out. If it is, your dryer still heats, but at such a low temperature that it takes three or four times as long to dry the clothes. If the element is partially burned out, replace the heating element. You can check for an ohm reading but will need to refer to the service manual for proper reading. This sometimes on the tech sheet located somewhere on the dryer. Usually between 9-13 ohms.
Cycling thermostat
Although this isn't a common problem, one of the thermostats that controls the temperature in your dryer may break and cause the dryer to heat poorly. If so, you need to replace it. The thermostat is usually a small, round, black device mounted to an oblong steel plate. The plate is mounted to the internal ductwork . This thermostat usually has four wires going to it. Check the 2 terminals that are opposite each other and are the closer together of the 2. These 2 terminals should have continuity. If not replace the thermostat.

if you have checked vent all the way out to termination point and sure that it is clear and not obstructed with damp lint then i would say you possible have a bad thermostat on the heater... this regulates how often and how long the dryer heating element runs and stays off.it has a open temperature and a shut down temperature... i would suggest replacement of that first... it is located on the heating element of unit... it is a round disk shape like bi-metal with 2 wires attached to it...
good luck to you....

Hello

When the dryer wont heat up and dry clothes it means that the thermostat/thermal fuse is bad and needs replacement. This part is located on the blower wheel housing inside the duct, please get back to me if you have any other questions.

Check the following areas thoroughly to address this 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.


4. Moisture Sensor
Most units will have a moisture or dryness sensor as well that will fail. inspect the sensor for faults. replace if necessary.

NOTE***(This unit is equipped with a dryness control board. if all points above check out ok, replace this board).

Hi, UNPLUG the dryer! Remove the rear panel of the dryer and locate the element on the right hand side. Plug the dryer back in and test to see if there is 240V going to the element posts. If there is voltage, but no heat, change the element. If it does not, you need to test the thermostats for continuity. If any of the thermostats are open, replace it. I hope this helps you.
Please let me know if this help or if I can assist you further.

Thanks

have you checked the dryer vent,wall vent lint trap for cloggs,if clogged it will hold the damp hot air in the dryer much longer and add to your drying time-mike

Make sure that your vent tube is not kinked or crushed behind the dryer and it all this is ok then you need to change your cycling thermostat. is it gas or electric
