I am getting a DR error code. I can dry clothes on low heat or on delicate on auto but not timed. I thought it was a door error but I can hear the button click when I push it in and I can dry on those two cycles.

I saw on a blog that if I took off the top panel there would be tech notes and a way to perform a diagnostic test. I found how to take the cover off on your forum but there isn't any notes.

I think I may have gotten the error before but opened and closed the door and it went away.

I don't want to buy a board if I don't have to. Is there any way to check it out?
Thanks
Paula
