3 weeks for part

LG dryer purchased in 2007. Dryer designed to send most lint through exhaust. The approved vent cap (for the outside) has a animal grate under the flaps. The lint kept clogging the grate, even though it was checked daily. Thermostat eventually blew. Took 3 weeks for replacement to come from Korea (on backorder). LG customer phone service needs improvement, it can be very frustrating. New dryer was unusable for 3+ weeks. When part was replaced we cut out the grates in the approved vent and removed some of the flaps. (exhaust system meets their design specs in the book). This seems to have fixed the problem. LG needs to re-evaluate their venting as it does not work well with US vent caps. Also you cannot use dryer sheets in this dryer (sales did not mention this, but we saw the warning in the manual before we used it, don't use liquid fabric softeners in the matching washer, it adds to the soap buildup problems).
