An enabled water shut-off valve, which prevents the icemaker from receiving water, can cause the refrigerator to seem stuck when attempting to dispense ice. The shutoff, typically located behind the refrigerator or near your main water supply line, is turned clockwise when enabled. Alternatively, the icemaker may be powered off and requires flipping of the manual power switch to restore power.
Chips of ice can clog the ice dispenser's chute if too many pieces attempt to come out at once. Once clogged, the crushed ice requires manual removal to clear out the ice chute and restore the ice dispenser. You can clean the chute with a plastic tool that breaks up the crushed ice without damaging the chute.
Locked controls on the front of the refrigerator disable the ice dispenser's controls and can cause the ice dispenser to appear stuck. Pressing "Lock" on the control panel for three seconds disables the control lockout feature and restores use of the ice dispenser, water dispenser and other refrigerator controls.
The freezer's temperature must remain at zero degrees to maintain its cooling control. The icemaker lowers to 15 degrees below zero to begin ice production. Higher temperatures cause melting ice in the freezer section and ice storage bin, leading to ice fused together into clumps. You may need to reduce the current temperature setting on your fridge's control panel. Once lowered, the jammed ice requires manual removal with a plastic object to break it up.
