The fan works only when the temperature goes up beyond a limit.the circuit gets triggered only after this point. check the voltage to this drive circuit and the trigger. heat the thermister and see if the fan works. if the heat is not heating up do not worry about this issue at all, normally this happens only when it drives up so much. Hope this helps? good day
