I would like your advice on a queation ive asked before please.I know i cant fit a new motor on a fan,when the motor is off a diffrent boiler model.I would be really grateful if you could help me unjderstand how and why it is that the old fan had a motor with the exact details on as new motor.The speed,volt and size the same,so as i said i cant get a fan until tue or wed(hopefully) and tried to get the boiler on temp.I cant understand how it worked ok before,then with new motor on,it doesent open aps up,but the aps is the same as the worcester aps,and the fan motor is off a worcester.I am just trying to see if there is a answer i am missing,the other thing is what does 56-63 w mean on the motor,ive also seen 45 w on different fan? thank you
