A Lochinvar 100208652 Low Water Cut-Off safeguards the equipment by interrupting function when water levels drop too low, minimizing the risk of damage to the unit.
The low water cut-off monitors water level conditions and interrupts operation when water drops below a safe point, protecting the heating and cooling unit from unsafe low-water operation. Its water level control design matters because accurate sensing and reliable shutoff support safer, more consistent performance in the HVAC system.
The low water cut-off may be approaching failure if the heating and cooling equipment shuts down unexpectedly, runs inconsistently or does not respond properly to changing water levels. Common indicators include visible wear, corrosion, mineral buildup, moisture exposure around the control or damaged connections that could affect sensing accuracy.
