Question about Sharp CD-DD4500 System

Open Question

The rotary cooling fans run constantly, even with power OFF.

The 2 rotary cooling fans in the stereo run constantly, even with the power turned OFF. Is there a sensor that is bad and thinks that the unit is too hot? Is there a do-it-yourself fix for this problem? I am planning to replace the fans because they are very noisy (I suspect they are on the verge of wearing out).

Thank you in advance.

    Sharp stereo model # CD-DD4500. Great stereo...

    Fans are worn out due to constant running. They are probably designed this way to keep the unit cool as there is power to the system at all times while plugged in. Fine with me, but I need to find replacement fans for this stereo. Anyone have a link for this type of replacement parts? The fan motors have RF-310T-11400 on them. Thanks for the help! ET

    I found the replacement fan motors on-line but do not have the info with me at this time. I will post it as soon as I can. The fan motors were about $34.00 apiece. You will need to remove the current wires and solder the connections to the new motors.

    The site for the parts is Partstore.com (1-866-925-7278). Part #: aa-rmotv0027awzz. It is listed on page 9 of the parts list for the Sharp cd dd4500. The motor is listed at $17.02. I replaced the fan motors and the silence is golden!

Onan 4000 Microquiet shuts down after running for 20-30 minutes. If I direct 2 high power (400+ CFM) fans to the underside of it -it will keep running indefinitely.


check the current draw from the machine
being a 4000 watt machine if you are drawing 4000 watts it is overloaded as that is the surge power available not constant power which is around 3500 watts
that would account for the requirement of fans to keep it cool
even if It is not 4000 watt what ever capacity it is it is running in an overload situation

When I turn the engine off the engine cooling fan stays on and does not shut off


depending on the engine temperature the fan is supposed to remain on after you turn the engine off, until the engine reaches a preset cooler temperature. when it reaches cooler temperature usually within 5 minutes or so it should cut off... if you cut it off and it is running 30 minutes later.. then there is a problem with the fan relay or temperature sending unit.

Check the direction of the cooling fan, if it is a centrifugal fan it will blow no matter what way it turns, but it will not blow as much if it goes the wrong direction. Check for the arrow and make sure it is going the way it says it should.

The cooling fan runs constantly even when the dvd recorder is turned off. Is this correct ??


If it runs for more than a couple minutes when the unit is completely powered off, it's not normal and should be checked.

These are fairly easy to disassemble and get back together, take it apart and find out what got stripped, It might be an easy fix, then again, it might be going back to sears. They will take it back no matter what. Hope this helps.

You might check the cooling fans on the condenser to see if they are running when the ac is on.If they are not check for blown fuse,or bad cooling fan relay.Do you notice if the ac cools better when running constantly,and the ac is not so cool when in traffic,stopping and going,and running slow?If so the cooling fan,or fans are not working.If the fan fuse and the relays check out fine,then replace the fan,or fans.If I can help any more please ask.roniecon@gmail.com
