Hi
Have this compact dryer 3kg, initially noisy which turned out to be the motor. The elderly couple wanted it repaired, so I ordered up the motor from MP, part No. C00207447.
Fitted part and tested ok, or so I thought.
Got a recall she said it wouldn’t dry on full heat. I tested and found it heating on both full and half heat. 12kw and 6kw approx.
Got another recall from her, this time I checked the drum speed and found it way to fast, this obviously not allowing correct tumble.The only thing I could think of was the new motor and on inspection found the shaft diameter a bit bigger, so I called MP and they assure me this is the correct motor, he even said that this motor would do the full sized dryers???
How can this be, as the gearing must be slightky different for each drum size?
So here I am stuck with a motor (iam sure is incorrect) which MP say is right?
Any thoughts?
Brian
Re: Creda 37373 Dryer
Nope correct part n’o only differance is the start capacitor should be a 5uf with that one, the old motor used a 7uf capacitor.
Re: Creda 37373 Dryer
how fast is way too fast the small dryers do turn quicker than the big dryers, i assume you have wired it up correctly,
the motor pulley size wont make a great deal of difference
to the speed of the drum.
the size of the capacitor wont make any difference to the motor
speed.Re: Creda 37373 Dryer
cant see how wiring it could increase the speed. Decreasing the poles or changing the frequency are the only two ways I know of to alter speed on an induction motor. Surely the size of pulley/drum size will alter the speed? The speed is way to quick, the clothes stick to drum like dist speed.
Thanks for taking the time to helpBrian

speed.After being in this game for about 30 years, i am well aware the capacitor is a start capacitor and wont alter the speed i was only advising that the newer motors require a differant capacitor which can cause the motor to stall, i wouldnt think wiring incorectlty would’nt make much differance as the heat is not taken off the heater on reverse tumble unlike the the condensor dryers.
Re: Creda 37373 Dryer
cheers johnny,, yes it’s the drum speed being the problem.. If I find out will let you know. I have come to a deal with my customer, which gives me the dryer to find out why its going to fast!!
This is why I ask advice, 30years you have a vast amount of knowledge for we who dont have that amount.
If you can come up with anything, please let me knowThanks Brian
Re: Creda 37373 Dryer
Intrigued as to how you can see it tumbling so fast or see the clothes, ‘plastering’, how did you check the drum speed?
Are you running it with the cabinet off, you can’t see through the door on these. 😕
Did you have the door open and trip the door switch?

sorry not trying to imply you were wrong about the capacitor i was just thinking out loud.
Re: Creda 37373 Dryer
Have you estimated the drum speed. Stick some black tape on the drum near the front, set it running and count the revolutions for 15 seconds, multiply by 4 to give you approx drum spend in rpm.
Re: Creda 37373 Dryer
how much bigger is the motor pulley shaft. any increase in this size will have a great difference going from small to to massive pulley(drum)especially if there is no reduction in rpm of new motor.
Re: Creda 37373 Dryer
Will get exact speed on Monday (takes me back a bit the 15 second count)but from experience its way to fast, its as fast as if not faster than distribute speen on an automatic.
Like clockworkone I think the motor shaft is to big.
I have taken a picture of the two motors, how can I post them here(I am sure that its been explained somewhere but humour me?).Thanks again for taking the time to help
