Dryer quit heating. Checked all electrical parts found thermal coupling o heating element bad. Changed it worked good about a week quit again. Changed it again worked about two days out again. Thought vent hose might be too long shortened it dropped it straight down about three feet of hose to lint trap. Replaced fuse. Worked about 3 weeks quit heating again. Any suggestions?
