“We just had this dryer installed and the "flo sense" light came on and the dyer was stopping after less than 10 min. So, we had our duct people come and clean out the dryer vent. That is now all clear and the same thing is happening.”

How long is your vent system, and are you using 90° elbows for it? LG's FlowSense™ Duct Clogging Indicator for the Energy Star® Certified LG 7.3 cu. Ft. Rear Control Gas Dryer with Sensor Dry, Model # DLG6101W, also indicates issues related to the length and configuration of the ducting, not just clogs. The system is designed to detect restricted airflow, and a vent system that is too long, or has too many bends/elbows, causes significant backpressure that triggers the FlowSense™ warning. FlowSense™ triggers on "D80" (80% restricted), "D90" (90% restricted), or "D95" (95% restricted) codes when air cannot flow properly, which is frequently caused by excessively long, kinking, or crushed ducting. But even if a vent is clean, if the pipe run is too long, it can slow the airflow enough to activate the sensor. The system can detect when the ducting is too complex, such as having too many 90-degree turns. If you are still receiving a FlowSense™ alert after cleaning the vent, you can remove the venting from the back of the dryer entirely and run a short test cycle. If the error does not appear, the issue can be confirmed as being a restriction in your home's venting (length/bends/clog)...^Ivan.
