What might happen if the low limit control fails?

The boiler could overheat
The combustion process could stop
The pump could cease functioning
Water could become stagnant

The correct answer is: The boiler could overheat

When the low limit control in a boiler system fails, it can lead to overheating. The low limit control is designed to maintain the water temperature within safe limits by shutting off the burner when the water temperature drops below a certain threshold. If this control is not functioning properly, there is the risk that the burner could continue operating even when water levels are critically low, causing the temperature in the boiler to rise unchecked. This overheating could result in severe damage to the boiler system, including potential explosions or system failure due to excessive pressure or thermal stress. Other options, while they might represent issues in different scenarios, do not directly relate to the function of the low limit control. The combustion process stopping is related to high limit control or other safety mechanisms, while pump failure pertains to mechanical or electrical issues, not specifically the low limit control. Stagnant water is more of a concern with circulation issues rather than a direct consequence of low limit control failure.
