Rob M Round Rock , TX July 30, 2015 F70 error code I was getting intermittent F70 codes from my dryer. I removed the top and checked all connections, everything was properly connected. I plugged it back in and tried it again, and it would start up and run just fine. It seemed that the built-up heat was causing the issue. I got the new part, removed the old one, installed the new one and replaced the top in about 10 minutes. After I plugged the dryer back in, everything is working perfectly again. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
