Replaced control board with OEM part from ApplianceParts Pro - fit exactly and remedied the problems. Simple to replace - turn off power (circuit breaker), remove internal door panel, remove control board cover and unplug wires/LED leads (the LED lead connectors on the board have a square tension slip ring around them that hold the leads - just pull these up away from board and they will release the leads) and then remove the controller board housing. The controller board is held into the housing with plastic clips - push in and the board is released. Install in reverse order. Run a system test as described in directions with new control board. Quick fix.
