What are some common troubleshooting issues?

Almost all dispensing problems are the result of:
Improper temperature
Improper pressure
Cleaning issues

Quick checklist:
Is the keg stored between 36-38° F, and is the same temperature maintained all the way to the point of dispense?
Is the CO2 pressure between 12-14 Lbs?
Have the Faucet, beer line, and keg coupler have been cleaned (with chemicals specifically manufactured for beer hose cleaning) on a regular basis?
