Susan R Newark , DE March 28, 2016 Error code f1 8 Control panel needed to be replaced. I originally ordered the wrong one. Got on your site's chat and your tech (I think it was Brent) was super helpful. He looked up my model # and got the correct part out right away. Received it in 2 days. After a couple missteps, it took about 1 hour to replace. We forgot to replace the lower flange, so we had to take it apart again. Bottom line, I was very pleased with the product and customer service I received. Thank you. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
