WM3987HW
LG WM3987HW All-In-One Washer/Dryer Repair

Most common issues on this model
- Drying phase heat and moisture removal
- Drain pump and filter
- Door seal and boot
- Water inlet and hose routing in a tight space
The WM3987HW is an older LG front-load washer/dryer combo. A single drum handles the wash and the dry phases, and it uses an earlier generation of LG combo drying technology in a compact footprint.
Combos of this age are often in closets and small laundry rooms, so access is limited. We first find whether the wash or the dry phase is the problem, then check the drain pump and filter, the door seal and the inlet water, and finally the drying path when clothes stay damp.
As an older model, it can need extra care with parts. We read the model and serial from the label before ordering anything and tell you beforehand if a part is hard to find. The price is quoted in writing before work begins, and the repair carries a 30-day workmanship warranty.

Is the WM3987HW a current model?
No, it is an older model. We still service it, and we confirm the model and serial from the label to check parts before we order them.
The wash is fine but clothes are damp afterward. What do you check?
One drum handles both phases, so a good wash tells us little about the dry phase. We check the filter, drain and drying path, then the door seal, which affects moisture on a combo like this.
Do you need to pull it out to repair it?
Often we do, because the hoses and the drain are behind it. We check access first, tell you if the machine must come out, and give the price in writing before we start.
