What is one of the common indicators of a low-pressure boiler malfunction?

A common indicator of a low-pressure boiler malfunction is unresponsive temperature gauges. These gauges are critical as they provide real-time readings of the boiler's temperature, which directly impacts its operation and safety. If the gauges are not responding, it may indicate a problem with the boiler’s controls or sensors, potentially leading to overheating or other hazardous conditions. Proper functioning of temperature gauges is essential for monitoring boiler performance and ensuring that it operates within a safe range. When these gauges fail, operators cannot accurately assess the system's status, which could delay necessary maintenance or emergency responses, increasing the risk of equipment failure or unsafe operating conditions.
