Turned on, runs a few seconds, shuts off with a #3 on display

Your bike to shutting off because the sensor is telling it that I don't know if you have eradicator, Dorothea have a loyal oil oil oil. There is a sensor that is telling your motorcycle to shut off because there is some sort of problem either. The sensor is bad or you have a problem somewhere. If your bike runs will ruin the engine you need to call a Harley dealer and asked them or go online like you are now on as somebody who has a bike like yours, but it sounds like to me that you have an issue with one of your sensors and the bike you shutting off to avoid further damage

It sounds like the flame sensor is bad. If thats not the case you may need to replace the control board. You should make sure the flame sensor is directly into the flame.

well in this case yes as the others suggest the oil/gas ratio is sort of important the other is and im sort of religous about this now but I store all my lil engines dry (no nothing in em) the gas they give us now just messes up these lil engines carbs one soultion is to add a generous helping of stp gas treatment in the tank (still keeping correct oil/gas ratio) and keep it running anyway possible to work the "dirt" out second these lil carbs are adjustable there should be a lil black round thing with a detent in it labled (HI) on side of carb , use a small piece of plastic tube from a old ink pen(bic) to turn this in/out to acheive your highest rpm (throttle floored)

Step 1:

Door Switch

If the microwave runs for a few seconds and then shuts off, a door switch might have failed intermittently. Check each of the door switches for any signs of overheating, arcing, or burning. Also check each of them for continuity. Replace any of the switches that is visibly damaged or that only has continuity intermittently

Step 2:

Main Control Board

If the microwave runs for a few seconds and stops there may be a short circuit in the main control board. Check other components first, these boards are often misdiagnosed.

Touchpad and Control Panel

If the microwave runs for a few seconds and stops the touchpad and control panel might be defective. There are several other components that can cause this problem, be sure to check any other components before replacing this board.

Touchpad

If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the microwave display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.

High Voltage Transformer

If the microwave runs for a few seconds and stops the high voltage transformer might have an intermittent short. This is not common. Check other components related to the microwave symptom first.

Thermostat

If the microwave runs for a few seconds and stops the thermostat might be defective. Watch our video on testing thermostat

E3 - No speed sensor reading. Unit shuts down. This is the most difficult repair diagnose. The speed
sensor is connected to the frame of the treadmill near the drive pulley on the front roller. There is a
small magnet on the side of the pulley wheel. The sensor tip must be no more than 5mm from the
magnet. If for any reason the distance is greater than 5mm the treadmill will shutdown
Adjust or replace speed sensor.
Treadmill: Speed Sensor Replacement
1. Make sure your treadmill is unplugged before you begin.
2. Remove the motor cover located in the front of your treadmill, it is held on by a few screws.
3. Locate your speed sensor; it is the small T shaped part with a red and black wire coming from it.
4. Remove the 2 screws in the speed sensor and remove the old sensor.
5. Place the adjustment holder on the frame with the open holes facing the pulley wheel, the prongs facing
up and way from the pulley wheel. Insert the screws but don't tighten fully.
6. Now place the speed sensor over the prongs with the square part facing the pulley wheel and the red and
black wire to the far right.
7. Plug the treadmill back in and slide the speed sensor until it is 5mm from the magnet inside the pulley
wheel, you may have to do this several times until you can position it so it no longer shuts down. Use 2
nickels to figure out the spacing. The width of 2 nickels is 5mm.
8. Once you find the correct position tighten the screws all the way; being careful not to touch any of the other electronics
9. Place the motor cover back on and enjoy your machine.
Also:
Use an epoxy to glue it. It is a plastic that is difficult to adhere to.

Suspect number one is not fan, lamp or Color wheel--optical light engine with dmd is.

error code 3 mean on a tx 5.0 sportcraft. I now how to fix it. I just did. And I didn't pay to find out from the internet. [email protected]. Unplug it. Take off the cover its 4 screws. 1 on each side and 2 in the front. On the right hand side there is a plastic wheel that is on the bar that rotates the belt. Its got spaces on the end of the wheel. Its passes between a mounted sensor that has a black, red, and white wire coming from it.as the spaces in the wheel flicker thru the middle of the sensor, the computer tells the speed rate. Thats how it knows how fast it goes. Mine was cracked in half and out of the sensor. The tx would fire up and shut down and blink 3 within 7 seconds of running. All I did was buy that glue that has 2 tubes on it like a syringe. Get a index card and fold it a few time to make a paper stick. Next make sure the wheel is ready as possible to be held together first. Then you bust off the cap to the glue squirt it on a piece of paper and mix the 2 glues together, stirring it. You only have a little time cuz the glue reacts to itself and starts to harden fast. Paint the glue on the bar, thick and quickly hold the plastic wheel together on it. Then just gob or let the glue drip where it is cracked in half. Key point! While you are holding the wheel together make sure its lined up with the sensor as evenly in the middle of it as possible. When the glue starts to hold, roll the bar with your hand to make sure the wheel is spinning freely thru (in between) the sensor. If it wiggles like its crooked its ok as long as it doesn't actually scrape or drag on the sensor. Put the cover back on and try not to step on the cover or on that side of the cover. The cover flexes and thats how I think mine broke. I got kids that think its a jungle gym. If the wheel is on and ok, it could also possibly be that the sensor is dirty. p.s. while you got the cover off sweep out the dust bunnies

This tv have a colors wheel,hear loud motor noises,humming noises,squiling or grinding noises,have pictures black and white.All these causes are by the colors wheel is worn out, warp rubbing against it motor or fiber plastic glass briddle about to brake aparts.Don't turn this tv on anymore until,u change the colors wheel or u will damage the projection engine.The colors wheel are hard to change for amatur and hobiest.Because involved taking out many machanical parts,before even can come to the colors wheel to take out and change it.The best course to to hire a Tv Tech.to do this job.The price colors wheel part and labors.Awhile back was about $500-550,now??

Sandpaper lightly scrubbed over the sensor tip to remove any contamination.

Sometimes cleaning is not enough and the sensor must be replaced.
