A:Answer I took the outside vent cover off to check and found that when the Best Buy installers attached the flexible vent hose to the outside vent, they pushed it too far in and blocked 50% air flow! I adjusted it and works fine. I am amazed at how the Best Buy installers found yet another way to screw up this install! Along with flooding my laundry room, and delivering a dented dryer, and finally this! Never Again!
