LG WM3677HW w/d combo not drying
Since last week our LG washer/dryer combo ends the dry cycle with a locked door, wet clothes, and standing water in the tub. I've got the service and training manuals and have gone through the diagnostics with no problems indicated. I opened and cleaned the dryer duct at the fan, replaced the cold inlet valves, and measured appropriate values at the heater, thermostat, and fuse in the dryer duct. Based on the spec in the training manual I've observed proper cycling of the valve that supplies water for the dry cycle and also proper draining during the cycle. I'm at a loss to know what to check next. Any ideas?
