LG In-Door Ice and Water Dispensers Don't Work?

My LG LFX23961SB (three-door bottom freezer) refrigerator's ice maker suddenly decided to stop working. At first it would make ice, but not dispense it and the water dispenser wouldn't work at random intervals of time. This was quickly followed by the water dispenser giving out completely and now the ice maker would refuse to make ice altogether, giving out completely. Any ideas that might help solve the problem without calling a repairman would be greatly appreciated. Thanks.
