Paul C Brockton , MA May 21, 2015 Appliance: Model FGQB4000FSO Dryer would start beeping six times and flash twice all by itself! Removed the top of the Dryer And replaced the Control unit. Very easily done. I have no experience working on Appliances , but this one was a no brainer!!! Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
