    What is an actuator motor in a boiler? 

    An actuator motor is responsible for controlling when the valves within the system open. It also has control over other components which perform actions based on input or environment-based signals, such as dampers. 

    This means the actuator motor can be activated by commands that are keyed into the boiler display manually, as well as fulfil temperature changes based on a minimum set temperature for the property at a certain time. 

    How do I know if my actuator motor is faulty? 

    The actuator motor is an electrical component which can develop faults due to wear and tear, or localised damage such as from exposure to water. A defective boiler actuator motor can be indicated by any of the symptoms below. Although a gas safe engineer will have to investigate inside the boiler unit to confirm if this is the case. 

    • Lack of hot water 
    • Hot water but no central heating 
    • Lukewarm tap water 
    • Leaks
