Clothes dryer not drying properly - Heating & Cooling

If your Whirlpool LTE6234DQ3 dryer is not drying clothes properly on the automatic/permanent press cycle, there are a few parts that may be causing the issue: Moisture Sensor: The dryer's moisture sensor detects the level of moisture in the clothes and adjusts the drying time accordingly. If the sensor is dirty or faulty, it may not be able to accurately detect the moisture level, resulting in clothes not drying properly. Try cleaning the sensor with a soft cloth and see if that resolves the issue. Thermostat: The dryer's thermostat regulates the temperature inside the drum. If the thermostat is faulty, it may not be able to regulate the temperature properly, leading to clothes not drying properly. A multimeter can be used to test the thermostat for continuity. Heating Element: The heating element is responsible for generating heat in the dryer. If the element is faulty, the dryer may not be able to generate enough heat to properly dry clothes. A multimeter can be used to test the heating element for continuity. Ventilation: Poor ventilation can also lead to clothes not drying properly. Make sure the dryer's venting system is clean and free of blockages. It is recommended to have a professional technician inspect and diagnose the issue if you are not comfortable with checking and replacing these parts yourself.

Check ventilation going out of house and inside dryer itself. If either is stopped up, clothes won't dry properly. If venting and dryer is completely clear, things I would check would be proper voltage going to dryer, heating element, thermal cutoff and high limit thermostat, operating thermostat, timer, and motor in that order.

try putting it in manual timer mode

More often When you experience a problem like this with your dryer it is becouse of a clogged dryer vent hose or the vent in the wall. Disconet your dryer vent hose from the dryer to see if it will dry properly. Then you will know if the dryer or the vent.

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.

check the vent or condensor depending on what type of dryer.

For a gas dryer:
Assuming the dryer is working properly and the control cycles are ok, look for things like a restricted venting system which inclides the exhaust, lint screen, etc. This would be the large pipe connected to the dryer exhaust that vents outside.

If it's an electric dryer, there could be issues with heating elements, thermostats, a control board, the timer, etc. Also check for any excessive lint build-up.

"Steam drying will get how but the air that comes later to actually dry is cold so the clothes never dry"

I am assuming "how" means hot in this sentence, if so, I think I can help! There is no "steam drying" phase for your dryer so what is probably happening is; the wet clothes are being heated properly [as a result causing steam] however if this steam does not escape frum the dryer it will simply condense back onto the clothing [leaving them moist/wet].
Check your flexible tube from the dryer and the vent on the outside of your home to make sure they are unobstructed. Hope this helps!

If the dryer heats at all and you are have to dry this long you have a blocked venting system in your home or a pinched dryer hose.

Your house dryer vent is clogged. There may also be lint in the internal ducts of the dryer.
