If it has only one ignition source then it sounds like a crossover is plugged or maybe one of the burners is not set correctly.

If it has multiple ignitors then I would suggest that a circuit board or relays are faulty.

Either way I would be very careful. If I remember right this is a big commercial steam boiler with 2 inch gas lines. That's a lot of gas.

Damper on a smith boiler is not working right and boiler won't stay on


If it's a flue damper, which I think you are talking about. You will see what looks like the tip of a 1/4" slotted(flat head) screw driver. That is the indicator if open or closed. It should be paralel with the direction of flue pipe. If it's not nearly exect unit will shut down. turn t'stat off or if that's not an option, turn temp down below room temp. wait a few min, turn t'stat on or above room temp and go to boiler as fast as possible.
See if damper is opening and stopping short of opening completely.
You may have built up soot and/or debris in flue causing it not to open all the way.
Please give full model # and do not force open. You may have dectectors that are picking up vapor,-gas probs.You mayl have to do a draft test. Better to be cold, than dead. Sorry for short explination

We have just bought a brand new 480cd gas rayburn boiler/cooker and it is making a very loud constant whistling noise. When the cooker part only is on there is no noise but just when boiler is going


This can be caused by several things. Incorrect Gas to Air mixture in the burner air intake valve. . Debris in the gas line to the boiler. To high a gas pressure. Depending on whether you installed this unit or not, will determine if you should try to repair or troubleshoot these issues. If it was professionally installed call the company that installed it. The only one you can't troubleshoot is the gas pressure. That needs to be done by a certified gas technician.

Hope this helps steer you in the right direction to solving the problem.

Air pressure switch is closed before the ignition sequence causing the boiler not to ignite can you advise solution


Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:


1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution: You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. The furnace's control board might not be supplying the voltage to the ignitor. If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

Boiler keeps tripping flame roll out switch. boiler is new. boiler also blows t&p when shut off manually.


When you are getting a flame roll out control trip its One of three. Not enough air in the room for a proper combustion. Your chimney/ Flu piping is clogged not allowing exhaust gases to escape or your gas is not tuned properly

I have a weather king model 90RJ - first time I've had hot air heat..When I turn on the heat, the blower turns on right away ( blowing cold air) - I understand that the ducts have to cleared of the cold...


When the furnace first comes on there is a induced draft motor that should come on first but that forces air up the exhaust or flue,not into supply air on ductwork. It is not unusual for cold air to be blown out when burner first turns blower motor on. This should last for a short period of time, no more than a min. or two. You can watch furnace cycle by removing top front cover, I should back up here and ask is this a gas or electric unit. If it is gas you should be able to watch burner flames for a short time before blower comes on. I really need more information so I can try to ascertain what is going on. Wish I could be more help. Thank you.

Burner not full force


Could be your gas pressure is too low. Also, there is a particular type of spider that likes to get into the gas line at the gas valve and spin a little web in there. I have often seen this as the cause of low gas pressure. If neither of these is the cause, I would suspect a faulty gas valve.

Janitrol/Goodman GMP075-3 Draft Inducer Fan Won't come on


most forced draft fans are powered by 120 volts . close to the fan is usually a plug that unsnaps. create a call for heat after turning off to clear safetys and see if your getting 120 to fan on initial call for heat. if you are then fan draft motor is bad, usually sold as an entire assembly replace exact as it came out. sequence of operation is..... stat calls for heat via common and white wire to furnace , 24 volts. ......board sences call and sends 120 volts to forced draft ........ motor runs and creates pressure on proofing switch,....... switch closes 24 to board and tells it draft fan is on......... board then energizes ignitor,....... after ignitior glows gas valve is opened and burner lights ........ either ignitor or seperate sensor rod tells board the burner lit........ and a few minutes later the fan comes on and hot air is blown out. if a step is missed or doesn't proof the furnace either trys up to three times to light or locks out. turning off power usually resets safetys and it will resume attempts to lite normally.
