Lamp never fires Unit goes right to cool/shutdown.


The ballast might have gone bad, you'll need to check the output voltage of it. In some projectors, the power supply/ballast are combined as one PCB instead of 2 separate boards.

Nail gun will not fire green light on gas ok after drop on congrete floor


A quick diagnostic check. First remove gas cell press nose against solid surface to dispose of any gas that may be in chamber.
1. Insert battery - LED should flash.
2. Press nose against solid surface - LED should be lit permanently (if still flashing possible fault moulded circuit board or fan motor micro switch lever, if flashing red green high possibility motor fault). Listen to hear fan running if not heard fan blade may have fallen off motor.
3. While still pressed against solid surface press trigger and watch LED - LED should blink off then light again (may flash red on guns newer than 2006) If does not blink fault either Spark unit (controller) or moulded circuit board trigger micro switch. To test for LED blink again release pressure on nose then press again. The blink indicates that a spark has been sent to the spark plug.
4. If 1 to 3 are OK problem most likely gas related or leak in seals. Ensure driver blade not still forward a possible fault of sticking forward after being dropped is nose slightly bent this traps the driver blade when first fired and does not return. (jammed nail gives a similar fault.) If nose is the fault it will require a new sleeve.
The moulded circuit board is normally cheapest then spark unit and sleeve roughly about same price the motor is most expensive.

Hope this has been some help to you.

What would be the cause of my Paslode fan not working batteries are good


First, check to make sure you have a flashing green light in the handle - if not start with the battery contacts / circuit board (Part #22 on the exploded diagram)
If you have a green light, I would look at the head switch -
1) remove the 4 bolts from the head
2) remove the 2 screws in the nose holding the cylinder to the handle assy
3) carefully remove cylinder by pulling nose out and down taking care not to bend your fan blades
4) On the handle assy you will find a metal tab with a small roller on it (Part #27 on the exploded diagram) - this is the actuator for the head switch, make sure it is not bent and that it actually works the switch inside.
5) If the actuator is OK, I would lean toward the head switch which is part of the circuit assy (part #22 on the exploded diagram) (It is possible you have a bad fan motor, but it is much more likely you would have a bad switch)
Let me know if you need further help

Fujitsu airon ASTA24LCC 2 flashes green and red then 5 red flashes any idea what it means


Had similar problem (ie. 2 green & red flashed followed by 5 red flashes - Fan blowing but not cooling ... I also noted that the outside unit fan wasn't going). Tried restarting several time after waiting only a minute or two after turning the mains power off but with no change. So turned the unit off at the mains power and then fired it up about 2hrs later and it was all working fine.

The fan motor is on all the time with the controls shut off. I have to shut the unit off with the main breaker. The ac works but again the fan never shuts off. On the circuit board the LED flashes 8 times,...


The indoor fan or the outdoor fan? If it is the indoor fan the thermostat may be wired incorrectly or shorted. If the red wire and green wire in your thermostat maintain contact, the indoor fan will run all the time.

When startin up it would show a message that air flow was blocked replaced the Thermal Sensor, now the timer lite blinks green then the lamp lite blinks yellow and the green light go out. I hav a new lamp...


Hi,

After the TV has shut down, without pressing reset: press and hold both the Device (Input) and Menu buttons on the front panel until the green light starts flashing. It will flash a two digit code: 3-4, 3-8, 5-7, etc. You may have to let the TV shut down a couple of times (without pressing reset) before it will give the code.

Please post the code to help me determine the section of the TV that has failed and what it will take to repair it. It may be a good idea to repeat the test a few times to make sure the TV is giving the correct code.

Let me know.so that we could proceed.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Gun was jamming up so i cleaned it now green light flashes but if i disconect wire put battery in then plug wires back in fan runs then stops and green light flashes again what could it be


the green light flashing means the tool is ready to fire. when the trigger switch is depressed or the safety activated the fan will run for a short time and automatically shut off. if the tool is not firing then it could be a loose connection of the circuit board or the spark unit. Let me know what the exact problem is and I will try and help further. Also check the expiration date on the bottom of the fuel cell.

Error code of 6 flashing light on circuit board,


There appears to be a short in the unit. Not sure where. The power to the fan is not interrupted completly when the fan shuts down, still feeding voltage to the fan, keeping it running slow. Before checking the wiring, please turn off power first.

Goodman furnace I think


Ok, a flashing 3 on a Goodman control board usually means that the pressure switch is tripping. A few things will cause this. One being a restriction in the exhaust or combustion air inlet. The second could indicate a faulty inducer blower motor and the third would be a blocked or bad pressure switch.
 
With the front cover off and door switch taped down, Have a helper turn the thermostat up to 75. You will be watching the circuit board for flashing lights and in a few seconds the inducer motor (the small fan hooked to the exhaust) will start. If this does not happen, we either have a bad circuit board or blower motor. If the fan starts rotating, inspect the hoses going to the small circular pressure switch. Sometimes they may get either water or debris in the hose and not allow the switch to sense pressure. If the hoses look OK, the igniter will glow an orange color and you will see this if you look thru the small viewing port. IF no glow, you could have a bad pressure switch, a bad ignition relay (found on the circuit board) or a bad igniter. OK so if the igniter glows, a few seconds later the gas valve should click open and send gas to the burners. The orange will turn to blue. If this does not happen, you have either a bad gas valve or bad circuit board. Finally if you get flame but it will not stay lit more than a few seconds, you may have a restriction in the burner gas train, a bad gas valve, a dirty or bad flame sensor or not enough gas pressure.
 
Knowing the sequence of operation will give you the needed information to talk with a service technician and cut down on diagnostic costs.
 
Try looking on the back of the furnace access panel for both model number and a diagnostic schematic. This will confirm what the flashing 3 code means for your unit.
 
Sorry, without knowing the model number, this is the best I can do for you. Good Luck!
