I have a brand new machine that worked fine, now suddenly is not drying. This is not my first LG rodeo, I had a similar model previously, which I took apart many times due to lint buildup in the drain reservoir, among other issues. The guts of this machine are different, is anyone familiar? I can't find any of the drain plumbing from the back access panel. I'm not even sure if that's the issue! When I run the dry cycle and measure the temperature of the air duct, it only gets to 75°F! I know it is heating a little bit, because it starts at 69°F (so it's not the heating element fuse). I checked the air duct temperature sensor for lint, it is clean.. any other ideas?
