I've owned the dryer for 3 months now and will have my 3rd service call on Friday. 1st call was for a bolt/screw that holds the burner assembly down that was never secured properly during manufacturing causing an increasingly bad rattle from the 1st day of operation.  Now the belt tensioner pulley has failed, tech was here and diagnosed but had to have a 2nd service call because he did not have the part to replace.  I'm glad I got the extended warranty as 3 service calls in as many months for a new dryer is very concerning.
