Carver PM350 ampliefier needs fan and fan motor replacement

Physically Obstructed If the fan is not running, unplug the refrigerator and remove the evaporator fan cover. In many cases the problem is do to the fact that the evaporator fan cannot operate freely due to an ice buildup on the fan blades. Sometimes one or more of the fan blades, in the case of fans equipped with metal blades, have become bent causing it to jam against the metal fan shroud. In the case of ice buildup, simply allowing the ice to melt away will cure the problem as long as the motor windings have not been damaged. If the problem is bent fan blades, replace the fan blade. Do not try to straighten the blade because it will be out of balance. Sometimes the problem is a buildup of dirt in the motor bearings and a good shot of penetrating oil can solve the problem...
Replacing a Defective Fan Motor Evaporator fan motors draw very little current and have a long life-cycle, but they can burn themselves out if their fan blade becomes jammed and unable to rotate. If the fan blade rotates freely, but the fan does not run, disconnect the fan wires at the fan and check for continuity through the motor windings using digital or analog multimeter. If you get no continuity through the winding, the winding is bad and you need to replace the fan motor assembly. The fan is usually held in place by three or four screws. Simply remove the old fan and take it with you to the appliance parts store to get an exact replacement. Check for Voltage If the fan motor checks out OK physically and electrically, check to see if there is voltage present at the fan motor's terminals. To check for the presence of voltage, set your digital or analog multimeter to its AC voltage function and attach the test leads using alligator clips. Position the test leads so the clips do not touch each other or the refrigerator cabinet. Plug the refrigerator in and note the meter reading. It should read 120 volts. A reading of zero volts means that there is no voltage reaching the fan motor. Unplug the refrigerator again before continuing the troubleshooting.. Bad Thermostatic Control No voltage reaching the fan motor could be caused by a broken wire between the fan motor and the thermostatic control, but broken wires are rare. To check for a broken wire, remove the thermostatic control from the refrigerator cabinet and take continuity reading between both ends of the wires. If the wires check out OK, replace the thermostatic control. Take the old one to the parts store with you to get an exact replacement.

follow this steps and fix iT. God bless you

1. Exhaust fan motorIf your exhaust fan motor is not running, there are a couple of things that you can check involving the motor to locate the problem. After removing the fan motor, you can manually attempt to turn the fan blades with your hand. If the fan motor is working properly, the blades should spin effortlessly. If this does not occur and the blades are taught, the motor will need to be replaced. Secondly, the fan motor itself can burn out due to time and usage. Using an ohm meter, the exhaust fan motor should read open for continuity. If it does not, then the fan motor has expired and will need to be replaced.
   
2. ThermostatAnother part that could cause the microwave exhaust fan to not work is a faulty thermostat. A thermostat gauges the air temperature, which activates the exhaust fan when required. If this part becomes flawed, the exhaust fan will not energize and the thermostat will need to be replaced.
   
3. Main control boardIf your exhaust fan is still not working and the microwave fan motor, wiring, and thermostat are operating accurately, the root cause could be with the main control board. Replace the main control board.

I would need to know what fan ( make/model) you have. Is the blade broken or the blade holder?

Hello There, blades oscillating are usually controlled by the motor. When the motor is rolling then the fan not oscillating is usually a minor problem. Usually the blades are connected to the motor using a rod which is directly connected to the blades.
If the oscillator assembly is faulty this could need replacement of a part. And this would require expert help. Which part exactly is broken? How well can you handle mechanical assembly parts? i could try to get you an assembly guide to help determine which part is faulty exactly but i need to know the above.
Hoping to hear from you soonest.
Thank you for visiting FixYa.

Most home centers that sell ceiling fans carry replacement Fab Blade Irons (that's what you're looking for).Try Lowe's or Home Depot.

I've heard similar refrigerator noises like yours before. Sounds like the evaporator fan motor, located in the freezer and runs only when the door is closed, is being obstructed, possibly by ice, possibly by some wiring or even a food item. You could have a defrost problem, but you dont mention any refrigerator or freezer temperature problem, so that is likely not it. It is also possible the evaporator fan motor itself is out of balance. If you remove the back wall of the freezer, you will be able to see if there is something obstructing the fan blade, if the motor or shaft is out of balance, when you close the door light switch, check the balance of the shaft, it should not have any wobble at all, in fact, if the fan blade is not attached, you should not be able to tell by looking at the motor shaft if the motor is running or not. Also, just happened to think, if one of the fan blades is even partially broken off, that will cause the motor to be out of balance. But if one of these blades is broken, it was broken by something else, either ice or something, and you may have to find the cause of that, otherwise it may happen again.

i had the same problem with my carver pm-350.
after a few search trough the web i found the right fan-motor at ebay.com (usa). the name of the offerer was thomething like "woodentrain...." it was offered as a elektromotor for H0-train (40V). the only thing you have to do is to cut the shaft on one side of the motor if you want to use it in your amp.
in my caase i had to search for the type (RS-365SH) (mabuchi?), but maybe your amp uses an other fan-motor..

Your dehumidifier has a circulating fan that draws the room air over the coils. If there's no air movement out the front or back of the unit, the fan motor may be burned out or stuck, or the fan blade may be broken. If so, you need to replace the fan motor or the fan blade.

Hello. after reading you're situation on this unit, I am not sure what this fan you are talking of, what role it plays in the system. Maybe a secondary fan for extra air flow if needed. You say it has come apart? What I picture is the fan blade not the motor is plastic and pieces have broken off. With many years with experience working on motors of all sizes, voltage, from 300 H.P. to 1/16 a/c motors and more, I would say you will be fine if you remove the broken parts of the prop/blade and run as usual. You say you don't run the fan but if you do run it and you say you have 75% of the prop left on it, as long as it isn't out of balance and the prop/blade is plastic, no damage will will take place at all. If you loose any more of this fan blade, I wouldn't use this fan until you can find another to replace it, but I strongly believe that you will be fine if you clean the parts out and run a you always would with not causing any damage at all to this unit. So, the answer to you're question is no, you will not cause any damage to this unit, and go right ahead and do what you wanted to do, it will be fine!! Contact me anytime if you have any more questions about any other problems you may encounter and need help.

PS, If this were a condenser fan motor, blower, heater inducer, you would need to replace the blade as the unit would not run anyway as it would shut down on high head pressure or you would have a frozen evaporator coil if this were to happen. I am talking on central a/c and Heating units only...

Generic problem for all Vacuums
The fan blades under the
Posted by roadrunner19 on Jul 08, 2008
The fan blades under the motor are broken I like my dirt devil triangle please help fix it.

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Changing the fan should not be a problem; it happens every so often if you pickup something big and the plastic fan breaks. The cost to repair is about $10.00 to $20.00 plus labor and you can repair it yourself if you are handy or take it to a local vacuum cleaner dealer in your area and they can perform the fan replacement. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.
