Hi, once the waterpump of the central heating system jammed ( blocked) :evil: . Single fase AC-Asynchronyous motor. No spinning components ar visible from outsite. If this happens: The motors current increments, te motor get hot en finally an internal thermal protection-switch
goes off. As the temperature of the motor windings decrements again, the protection switch closes again en everything starts over. But after a few error-cycles the motor could possible turn again. So I am not aware that a jam happended. I would like to a have alert to alert me that the pump was blocked. :idea: LED or whatever. So that I can decide to replace the pump. Any suggestion ? :roll:
