AS601HHB0
LG AS601HHB0 Air Purifier Repair

Most common issues on this model
- Fan not responding to the automatic speed setting
- Air-quality light stuck on one reading
- Replacement filter that does not clear the light
- Rattle or hum at higher speeds
The AS601HHB0 is a PuriCare 360 air purifier with True HEPA filtration, a current LG model. The 360 degree body draws air from all sides, so it is commonly placed in a bedroom, home office, or living room where there is clearance around it.
We start with the part owners notice least: the sensor opening. Dust there can leave the automatic setting stuck. After that we check the HEPA filter seat, listen to the fan on each speed, and confirm that the filter reset clears the light. A purifier covering this much floor area moves a lot of air, so even a small imbalance in the fan shows up as vibration we can hear.
Before ordering parts we read the model and serial from the unit label. The price is in writing before we begin, and our work is backed by a 30-day workmanship warranty.

Does True HEPA change how you service it?
It makes the filter seat and condition the first check, since a loaded or crooked HEPA filter restricts airflow. We inspect it, then move to the sensor and fan.
Why is my purifier always on the same speed?
Either the sensor opening is dirty or the fan is not following the sensor. We clean the opening, check the reading, and test the fan control.
How do you decide whether a part is needed?
We test first: sensor reading, fan on each speed, filter seat, and reset. Only then do we quote a part, with the price written and approved before we order.
