How do i clean the condenser on my lg sensor dry

Unsure if your model has a front housing to be checked.

Dryer Failure Code Condition Check/Repair F1 Condensate drain overfilling Check condensate reservoir pump and drain tube. F2 Maximum drying time exceeded (3hrs) - Check for tripped circuit breaker or blown fuse
- Check ductwork for lint build-up
- Check hi-limit and cycling thermostat
- Check heating element F3 Thermistor fault - Open thermistor, replace
- Bad wiring to thermistor F4 Too much lint in the lint filter, front housing, or in the condenser Clean lint from lint filter and/or condenser F5 Fault in the moisture sensor - Lint covering sensor in front of housing
- Bad sensor
- Bad wiring to sensor

Sensor defect or connection cable lose.

If it’s taking a long time to dry, check venting for obstructions or kinks.

The sensor is sensing that the load is done. Even if it is not completely dried. The two sensor bars inside your dryer on the filter system(stick your head in the dryer and look down-you will see them) are most likely lightly coated with dryer sheet fabric softener film. Interferes with sensor. Clean with googone or alcohol. Or just use timed drying.

usually do to condensation which is a result of bad venting in the blower, the tubes, the glides, and the door, and even a bad moister sensor check it with a meter for continuity and for amount of ohms but at a high temperature not room temperature

do you mean a condenser dryer?, as steam is water doesn't dry anything to well, if it is a condenser dryer the check filter or clean filter light should always come on towards the end of the cycle (varies between models some have both clean filter and empty tank lights on at end of cycle just as a reminder to do so and some don't have any lights), it is simply a reminder for you to clean the filter after each use unless this is something that has only just recently happened

The problem is likely due to lint build up in the condensing unit. I found a solution here:

I also had a softball size ball of wet, packed lint in the condensing unit. I found that the unit can be cleaned without tools or dis-assembly by:

1. draining the water.
2. laying the washer on it's back.
3. removing the hose clamp on the rubber bellows that connects the drum to the condensing unit (right hand side of machine).
4. digging the lint wads out with your fingers and a small screwdriver.

Happy drying!

I called LG...they said to unplug the dryer for 5 min. to reset the timer ...this solved the problem.
They also said not to use dryer sheets during the sensor dry cycle as the coating on the dryer sheets causes the sensor to malfunction as it can't read the humidity level in the dryer.

CD means cool down, press the pause start button, the door lock will open. It is an anti crease cycle. It mentions it in the owners manual, but it is hidden deep in the drying section.
