SOURCE: Furnace pilot is on, pilot ignitor continues to click, no main flame

sounds like the sensing bar on the spark ignition is dirty.....a wire brush works nicely.

You need to replace the Thermocouple. (pilot safety device) It would be best to call a Technician about this.

SOURCE: Gas boiler won't stay lit!

The burners and pilot need to be cleaned.
Turn off gas and power, remove the burners and pilot. Clean with a brass wire brush. (Steel wire can be used but very carefully) Remove all rust dirt etc. reinstall and it should fire right up.

The solenoid is not opening the gas valve so you need to replace the gas valve, as for price I have no Idea...
But please remember to get a GAS SAFE REGISTERED engineer to carry out this simple replacement...

Hello,If you cleaned the flame sensor and it is in the pilot flame,Try adding a ground wire from the pilot assembly to any close screw to boost the (pilot on) signal.Also if the valve has been sitting for a while give a tap once during (pilot on) to make sure the diaphram is just not hung up.I would hate to replace the valve and still have the same problem.

Sime boiler pilot light


Sounds like an old boiler. It is not on timer and has to be lit manually. Push in the gas button and hold and push the sprung ingnition button to greate spark. Continue to hold in gas button 1-2 mins and release. The pilot light should then stay on. The flame will have heated the sensor in the combustion chamber and the boiler thinks that there is a flame and will allow the main gas jets to light when demanded . If the flame does not stay on clean the sensor prongs with emery cloth but do wait until they are cooled. You have open up the combustion chamber for access
The 1-2 mins above varies

Removing the front cover or turning the line switch off and back on causes a "HARD" reset to the furnace. That means, it breaks the line or supply voltage to the furnace and causes the main control board to reset. The main reason for requiring a hard reset is a failure to fire up correctly. There are several reasons for this to happen. If or when the flame sensor detects a flame determines the whole process. When the thermostat calls for heat, the ignition controller delivers spark to the pilot assembly and the pilot gas valve opens. If the sensor detects a pilot flame, the main gas valve opens and the main burners ignite. The pilot flame can be pulled away from the sensor when the main gas opens just long enough to cause this type of failure before the main flame is sensed. The furnace will shut down thinking it is feeding in raw gas with no pilot present to ignite it. All of this happens in just a few seconds. If there is a small window in the burner cover, you can watch it fire after the reset for a clue to the cause. If there is not an inspection window with a sealed combustion chamber to watch it through, it would be best to call a good tech. as it is dangerous with such a short period to ignite while all that gas is flooding the combustion chamber. Check to see if the line from the pilot to the gas valve is tight. If possible, try to move the sensor a little closer to the pilot. If this does not work, best to call a tech. who is familiar with your furnace. Other test with an open combustion chamber are very dangerous and best left to the pros.

Sounds like its an intermittent flame failure on trial for ignition. Look for the pilot flame drifting away from the sensor when the main valve opens.

When the heat cycle calls for gas there is no ignition is my gas valve bad?


I don't know what kind of furnace you have. But most furnaces have some sort of pilot first than after it is proven than the main gas will come on. Either a standing Pilot with a thermocouple. A hot surface ignition or Spark ignition with a flame sensor. Or a direct fire system where hot surface or spark ignitor start first than all the burners send a 1 sec blast of gas which is proven by the flame sensor if it proves the gas valve stays on.....
In what you have said you have 24 volts to the gas valve and it has not lite. then does the gas valve have a pilot tube???Does it have a thermocouple?? Do you smell gas?? If you don't smell gas then the main part of the valve has not opened. The Pilot valve has to open first and prove before the main gas will come on. I hope this helps. If you still need help repost with the name and model # of the furnace.

Water heater pilot light


it also sounds as though the pilot injector could be blocked so when the boiler comes on it extinguishes the pilot & then when the burner goes off boiler shuts down, or also the pilot rate maynot be set right, so when the main burner kicks in it robs the pilot of the gas it requires.
It could be that, or there is lack of ventilation for the boiler, so you get flame lift off when the boiler fires?
