Gas boiler clicking and no heat getting to radiators

Just moved into my new flat and the classic lxff & ff fanned flue gas boiler is not first the radiators were starting to heat up slowly but then the boiler started clicking very loudly and now there is no heat getting to the radiators at all and when i turn on the boiler it clicks all the time.the pilot light is on and i bled all the radiators and turned them all on full, also the hot water is working fine.there is no instruction manual and the only controls on the front are the on/off switch and the the knob to turn the heat up and down.any idea what the problem might be ?,any help would be greatly appreciated as i am clueless !!

I have a coleman modulating furnace it is propane The buners seem to be corroding

There are 2 types of burners. Atmospheric (or ribbon) type & inshot. I would imagine yours are Atmospheric...the longer type burners that protrude into the heat exchanger if they are corroding. Which also means you have an older furnace. Condensation can occur if there is not enough removal of flue gas...or... water is getting down into the burner from the flue. Have someone check the draft pressure to see if it has a proper draw when running. Coleman Evcon also made a furnace that is called a blendaire system. This system has a lower control board @ the furnace & and upper control board in a fan on the roof. The purpose of the fan was to blend air into the return from outside via roof fan to introduce fresh air in a tightly enveloped manufactured home, along with pressurizing the attic space to help keep the attic dry. If you have this type of system, your motor may be not working on the roof. Good luck!

My boiler keeps making a ringing sound. Like a small bell on a bike. What could be causing this noise

Note sure if its the same thing but my boiler (halstead Best 50) made a ringing sound just like you describe. It was the flue fan blades just catching the metal surround of the flue vent on occasions. It only happened when the boiler had been running a while. A new fan was fitted and everything ok now.

Worcester combi gas boiler 3.5 highflow is constantantly dripping water at the external flue position over flow pipe

water vapour is one the main products of combustion of gas. With a standard efficiency boiler, upon initial heat up when the flue is cold this vapour can condensate on the inner wall of the flue but should stop once the flue heats up, to stop this condense dripping back on to the heat exchanger the flue should be tilted towards the outlet and thus on initial heat up water can drip from the flue. with high efficiency (condensing) boilers, condensation will occur in the flue and secondary heat exchanger during normal operation, dispense of this condensate is accommodated for in the boiler and therefor the flue should be tilted towards the boiler, if not the flue will drip constantly.

My ariston boiler is not working it just shows A 01 have reset but still nothing any ideas?

Basic checks:-
water pressure in boiler
gas supply on
Turn boiler on then:-
does the fan come on - u can hear this at the top of boiler
does the gas valve click on
has there been a burning smell near the lower front [check the pcb]
check the co-axial flue is ok with no gaps between inner & outer [rare but not unknown]
If it's a condensating boiler check the condensate outlet tube for ice blockage especially in current weather

Boiler Venting.

There cannot be controlled venting of the flue , the products of combustion must have free flow to escape , The heat exchanger is above the burner which heats the water if you thinks this is high then maybe you a pressure problem . Or contact the makes tech line and ask them what they think the consumption might be for you heater .You may find this on google

Fan runs continuously

the air pressure which does not controll the fan it is a safe guard for the gas/oil burner to ignite nowing that the fan is running ( air switch normaly negative /positive prssure n/o,n/c circuits. it could be that your boiler is designed for a cant think of techinacal name but when in centre of house/factory and has 1 or more boilers connected to flue etc the fans run when only power to boiler is on , non vented system ? it could be a simple link to remove in controll panel i would phone technical help for manufacture ?
