Seams like fan not working - Dell (6F858) Cooling Fan

I had a unit that was similar and there were screws hidden under plastic caps. If you can see plastic catches, you use a tool called a 'spudger' which is like a blunt butter knife. They come in plastic or metal.

If all other functions seam to be working , It could be a auxiliary Thermostatic Expansion Valve ( TXV ). Diagnosing rear problems

I have never used a machine to free motion quilt. That said, I have had issues sewing over thick seams. Since your machine runs smoothly otherwise... I think it is the thickness of the seamed area that is causing your problem. It may be too late but you could try trimming your seams so the layers fabric graduate to full thickness. Or you could use a chop stick or popcicle stick to press down on the thickness as you guide the machine over the seam. I also suggest that you Fan your seam allowances where your blocks come together. You can see how that is done here. http://www.allpeoplequilt.com/videos/v/62207505/machine-minute-bulky-intersections-fanning-seam-allowances.htm

check out your thermostat and your fan sensor could be failing

check the capacitor on the moter or just replace 12.00 bucks. if it doesnt work you need new moter.

If the manually switch works it seams there is nothing wrong with the ac unit itself ...and it may be a poor contact on the remote (for the button that starts the fan ) ..If you think you can manage open the remote ..and clean with alcohol the contacts..both sides..on the main board..and the inside the rubber button contact ..and put it back ..and see if the function is working ...If it is not ..you will need a replacement in order to work ...My advice ..just to see if it is a remote issue ...try to find a somilar one ...(or a universal ) and see if it works before going and buy one ...cause even if it seam to work manually ..this is not excludes a strange malfunction in the infrared board of the ac .

Put on the work gloves. Turn the Samsung rear-projection television around so that the back is facing you. Use the Phillips screwdriver to remove the screws from the bottom left, the bottom right and across the bottom of the TV. Remove the screws that are directly above the ones on the bottom left, the bottom right and the bottom of the TV. Put the screws aside

Insert the flat-edged screwdriver into the seam between the bottom plate and the back of the TV. Wiggle the flat-edged screwdriver into the seam to loosen the bottom plate. Remove the bottom plate and put it aside.
Locate the fan assembly inside of the TV at the left corner. Use the Phillips screwdriver to remove the screws from around the fan assembly. Put the screws aside.

either the lamp's seams aren't taped over with foil tape to prevent the premature shutdown due to the heat sensors being triggered, or the fan under the the colorwheel has stopped, maybe due to a piece of lamp from a previous lamp explosion being stuck in it, or the power supply/ballast is bad, or the eca on the engine itself is bad. The lamp is the easiest to try first. There should be foil tape over the seam on the side of the lamp you can't see when it is installed. If this doesn't work, take the front bezel off amd get where you can see the fan under the colorwheel and tunnel and power the unit up and see if the fan comes on. If it does thenthe eca on the engine or the power supply ballast is most likely bad and these are major repairs.

Contact the Manufacturer or an electrictian, it could be a vault in the fan itself.
