A common cause for this issue is an expired or clogged water filter that blocks the flow entirely. I discovered step-by-step replacement instructions at [[ https://manuals.online/frigidaire | https://manuals.online/frigidaire ]] which clearly show how to remove the old filter and install a new one safely. After completing the replacement, the dispenser started working immediately. It’s surprising how such a small maintenance step can prevent what feels like a major appliance problem.
