Hello. I got a PF code today on my Whirlpool Duet dryer. I turned it off and turned it back on. PF code was gone, but when I selected the dryer setting and pressed start, you hear a “click” and the board starts to run through its cycle, but neither the dryer tub starts tumbling the clothes nor does the air/heat turn on. However, the display seems to think that “everything is ok”. Any advise? Thank you.
