Causes of a Stuck Shower Temperature Control

Mineral Buildup

One of the most common reasons for a stuck temperature control is the buildup of minerals.

Hard water, which contains high levels of calcium and magnesium, can leave deposits on your shower fixtures.

Corroded Internal Components

Over time, the internal components of your shower control can corrode, especially if they are made of metal.

This corrosion can cause the control to stick or become difficult to turn.

Faulty Thermostatic Valve

Some modern showers come with thermostatic valves that automatically adjust the water temperature.

If this valve malfunctions, it can cause the temperature control to get stuck.

Damaged Cartridge

The cartridge inside the shower control can wear out or get damaged.

This can prevent the control from turning or adjusting the temperature properly.
