156 views

When a circulating pump stops working, the flow of heating or cooling medium halts, leading to an uneven distribution of temperature in the system it serves. In heating systems, this can cause rooms to remain cold as hot water isn't circulated properly. In cooling systems, similar issues occur with chilled water. To resolve this, check the power supply, ensure the pump is not seized, and look for any blockages or air trapped in the system. If these steps don't work, it might be time to consult with a professional for repair or replacement.
