UD701KOG3
LG UD701KOG3 70-Pint Dehumidifier Repair
Most common issues on this model
- Air filter clogged and restricting airflow
- Fan speed not changing with room conditions
- Compressor running without lowering humidity
- Coil frosting in a cool space
- Drain connection and bucket seating
The UD701KOG3 is a 70-pint LG PuriCare dehumidifier, now an older model. At this capacity it is intended for large basements, open lower levels, and whole damp floors where a mid-size unit would run constantly.
It pulls air through multi-stage filtration before the fan, and an air-quality sensor sets the fan speed automatically. That makes airflow the first thing we inspect: a clogged filter or a dusty sensor can leave the fan stuck at one speed or cut moisture removal. After that we check the coil for frost, the compressor start, the bucket and drain path, and how the unit responds to the humidity setting.
We read the model and serial from the label before ordering parts and give you a frank view on whether a repair makes sense for an older unit. A written price comes before work starts, and our repairs carry a 30-day workmanship warranty.

Why is the fan on my UD701KOG3 stuck on one speed?
The unit adjusts fan speed from an air-quality sensor. A dirty sensor or a clogged filter can mislead it. We clean and test both first, then check the fan motor and control board.
My 70-pint unit runs all day but the room stays damp. What do you check?
We check the filter and airflow, the coil for frost, and the compressor start. In a large damp space, restricted airflow is a common reason for low output.
Do you replace the filter during the repair?
We inspect it and tell you its condition. If a replacement is needed, we confirm the part number from your label and quote it first.
