Samsung microwave oven Model # SMH9151S. Turntable not turning fan inside (not the exhaust fan) is not working either.


It may be a failed relay on the control board, which I repair affordably.

LIGHT, turntable, and fan don't come on

  1. Exhaust fan motor If 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. Thermostat Another 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 board If 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.

We have a kenmore ultra wave microwave and the fan has stopped working and now the microwave won't operate. Any suggestions?


see this causes and fix it .God bless you
Exhaust Fan Motor If the exhaust fan does not run the fan motor might be bad. Remove the fan motor from the microwave oven and see if the blades can be turned by hand. They should turn very freely, if they're stiff the fan motor will need to be replaced. The fan motor can also burn out. To test this use an Ohm meter. The motor should have continuity. If it does
Thermostat If the microwave exhaust fan is not working the thermostat might be defective. The thermostat senses the air temperature and turns on the fan as needed, if it's defective it won't turn on the fan. Watch our video on testing thermostats.

Main Control Board If the microwave exhaust fan is not working check the exhaust fan motor and wiring. If they are good the main control board might be defective.

Which way does the rear fan go in a compaq computer tower


The proper installation of a CPU fan is often the subject of debate. Though there are conflicting theories as to which direction the CPU fan should face, there are methods to ascertain which CPU fan installation best suits your needs. The determining factors of your CPU fan installation direction include the manufacturer specifications, your case design and the specific design of your heat sink
Horizontal Installation
  • The installation of a CPU fan horizontally to the plane of the motherboard is the most common installation orientation there is. Your options when installing your CPU fan are to blow cool air onto the heat sink or to pull cool air through the heat sink from the motherboard. Horizontal installations show negligible advantages in either installation direction. The differences in temperature usually vary by only 1 or 2 degrees Celsius. The main point to consider when installing a horizontal CPU fan is the location of the rear exhaust fan on the case. If the rear exhaust fan on the case is parallel to the processor, it is advantageous to have the fan pull cool air from the motherboard and push it out above the heat sink. This is because the case fan will quickly draw that hot air away from the CPU and out of the case, allowing for quick cooling.

Vertical Installation
  • Vertical, or tower, heat sinks rise high enough off the motherboard to allow for a fan to be installed perpendicular to the plane of the motherboard. This allows for cooling to go from the front to the back of the case, as opposed to going from the bottom to the top. Optimal installations for vertical heat sinks are blowing toward either the back or the top of the case. If there is no exhaust fan in the top face of your computer's case, it is more effective to orient your fan on your vertical heat sink so that it blows toward the rear exhaust fan of the case. If there is an exhaust fan on the top face of your computer case, it is almost always more effective to mount your CPU fan so that it blows air up toward the top of your case. The reasoning behind this is that hot air rises and will more naturally flow off the top of your case. Also, top-mounted fans are usually larger and allow for faster airflow out of the case.

Manufacturer Recommendations
  • It is often the case with nonstock heat sinks that the manufacturer has designed the heat sink's fan to be mounted in a limited number of orientations. This is usually evidenced by limited mounting notches on the heat sink itself. Most aftermarket heat sinks use technologies such as heat pipes that have specific cooling needs to operate appropriately. Because of this, it is important that in any CPU fan installation you follow the manufacturer's installation instructions.

MY LAPTOP IS OVERHEATING WHAT SHOULD BE DONE?


Most likely yout exhaust fan is clogged with dust and lint. You didn't give a model number but some fans are easier to acces than others. Some require disassembly. Excessive heat will ruin your motherboard eventually. If you are not comfortable taking it apart you can try to blow compressed air back throught the exhaust vent for a temp. fix. If you do that stick a paper clip or something else in between the fan vent and fan blades to prevent the fan from spinning when blowing it out. ( a spinning fan will produce an electrical current back through the motherboard connection which you don't want ).

I need a replacement motor for a NuTone Model LS-80SE exhaust fan but can't find one.


Home depot usually has a good selection of replacement fans. They usually are a fan on a mounting plate, not just the fan motor itself. Sometimes you have to purchase the entire fan unit just to get the fan motor plate inside for a replacement part.

Printer message reads error 13


Error: 927 Service Fan Stalled
Check the main exhaust fan first. All models of these printers have a main exhaust fan. The main exhaust fan is located on the top of the printer, on the rear left side. 
Make sure nothing has fallen down into the main exhaust fan that could be blocking it. There are vent slots/holes in the top cover of the fan, on the left-hand side. Look through these vents/holes. 
If there is an item stuck there, see if you can remove it. If not, you will probably need to have a technician remove the top cover unit and extract the jammed item from the fan. 
If nothing appears to be blocking the exhaust fan, power off the printer and let it sit powered off for at least a minute. 
While the printer is turned off, check to see how it is plugged into the wall. It should be plugged directly into a wall outlet and not through any sort of surge device or power strip. (Power strips and uninterrupted power supplies can cause a low amperage problem in your printer, which could trigger a 927 error.) Even if it has worked on this surge device for months, try connecting the printer directly to the wall. If the printer is already plugged directly into a wall outlet, try it at a different wall outlet. 
When the printer has been off for more than a minute, power it on and see if the 927 error returns. 
If the 927 error does not return, try printing again. If the printer works as expected, continue using it as you were doing before the error arose. The 927 error may have been just an isolated incident. However, keep an eye on it for the next couple of days to see if the error returns. 
If the 927 Fan Stall error continues to return when you power on the printer or when you try to print, the printer will probably require service. 

If you are a technician working on a printer that has ONLY one fan installed, check the cable connecting the main fan to the engine/system board. Make sure the connections at the ends have not come loose and that the cable itself is not damaged. The parts that are most likely to need replacing are the main exhaust fan or the printer's engine/system board.
Some printer models also have a second auxiliary cooling fan, sometimes called the cartridge cooling fan. Printers that have this fan are the Optra T614, T616, the Lexmark T622, the T63x series (630, 632, 634) and some models of the Optra S 2420, 2450, 2455, and Se 3455. Note: The second exhaust fan was eliminated on some later models of these S series printers. The auxiliary cooling fan is located on the back of the printer, on the right-hand side. 
Check the fan as you checked the main exhaust fan. Look into the vents. Make sure nothing has got stuck in this fan. 
Turn the printer off and on again to see if that clears the 927 error first. 

If you are a technician working on a printer with this error that has more than one fan installed, you need to establish which fan is causing the problem. You can perform the following checks:
Check the main exhaust fan first as it is usually the cause. If the main fan appears to be fine, check the cable connecting the auxiliary fan to the printer's engine/system board.  
Power on the printer. During the warm-up sequence, both of these exhaust fans are supposed to turn. If one fan turns and the other does not, the fan that is not turning is the most likely cause of the problem. 
Measure the voltages coming off the engine/system board to those fans. If one particular fan is not getting voltage, the problem lies with the printer's main system/engine board or that particular fan or cable. 
The Lexmark T622/622n model printers also have a fan on the printhead unit. This fan is not visible from the outside of the printer, so you will not be able to check it visually. Power the printer off and on. If that does not clear the error and this fan is the cause of the problem, the printer will require service. 

If you are a servicer working on this printer model, follow the steps listed above for the auxiliary fan, but adding this third fan to your list of checks for the cause of the 927 error.
