Thermal Dynamics cutmaster 81. when turned on it cycles blowing air but no arc. two green lights are flashing. pulling the trigger doesn't do anything, air keeps cycling

Hi; Check the following troubleshoot and see if you can ID the problem:
Problem: Gas flows continuously when power is turned on, AC indicator flashes 1. Torch switch is activated (closed) before user turns power on. a. Release torch switch. 2. Faulty torch switch a. Check torch switch for continuity. Replace if necessary.
Problem: Gas flows continuously; Torch will not pilot when torch switch is activated; AC indicator ON 1. System is in SET mode a. Change to RUN / Rapid Auto Restart / SET switch to RUN (up).
Mostly of the problems found is that customer has the switch line on to SET instead of RUN.
Hope this help. Have a good afternoon.

KTM 625 SXC Bike wont start.

Classic dirty carb problem. You will need to pull the carb off. Soak it in a gallon carb cleanerwstariner($15)-available most auto parts stores. Get a set of torch tip cleaners($5) at Lowes/HD. A can or two of carb cleaner spray. And a good source of compressed air with rubber tip air nozzle. Best to let it set for atleast 2 days in the cleaner. Bottom out any adjustable screws and right down # of turns for easy assembly. Pay attention to all the little air/fuel circuits theres even 1 in the float bowl that does a hard 180 thats tough to get clear. Thats where those torch tip cleaners will come in handy. Blow every circuit with air---watch out for any orings stuck in the carb they wiil fly across the room never to be found again. You usually can reuse the all gaskets so no parts needed.

Air is coming out of the hole where you light the pilot and blows out the i cant light the pilot. it was working fine until this morning

You have a major down draft. You will need a torch to overcome the air coming out of the pilot hole. Or if the heater has another door that can be opened to allow the air to escape there.

The heater in my central heating is not getting turn on but the fresh air and cooling is getting turn on

Check the pilot light.Older standing pilot systems use thermocouples to verify the pilot is burning before the gas valve opens.If the pilot wont stay lit replace the thermocouple.
Newer systems light the pilot.On a call for heat the igniter lights the pilot. When the heat is verified the gas valve opens . Some systems use an circuit board with flashing led lights to help troubleshooting.

Check contacts in tip and be sure it is all lubed correctly. If you have good air pressure and flow it should arc after pulling the trigger for about 2-3 seconds.
