Mario A Hoover , AL March 23, 2015 Appliance: Model 790.9642940A F 10 error code bad clock/timer board Ordered a new board. Received it within 48 hours. Removed the back panel of the appliance, disconnected the various wires, unscrewed the old board. Removed the faceplate from the old board and attached it to the new unit. Screwed the board into the mount, reattached the wires and replace the back panel. That was it. Could not have been simpler. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
