it sounds like delayed ignition, this is VERY dangerous, you need to verify sequence of operation and fuel air mixture.

Hi joseph_dorri,

Vulcan has backup, if you ever do need a spare part for your Vulcan, it's good to know they are readily available across the country and can be serviced by most plumbers or electricians.

For contact details please click this link.

If you live in Melb, you may also try Tradelink (for the spare parts) or Thermal Products (for any electrical temperature controls etc). Both are in Thomastown.

Hope it helps.

Thank you for using FixYa.

SOURCE: Hi I have Vulcan

When on, Is the pilot strong and blue flame? If its yellow the flame is being pulled away from the T/couple or Pilot generator it will cause the unit to shut down.If the pilot light is strong it could be the T/couple or pilot generator.
It could also be the high limit switch kicking the pilot off but that's usually the case.
you should have atech look at the problem as there are other reasons that could effect its operation

My old vulcan inbuilt gas furnace now has to be run at max fan and gas to get it to heat - can you suggest what might be the problem and how to fix?? Thanks JH

Does it have good air flow? Air Filter not clogged, fan spins full speed? Lack of air flow, volume, can trip on overheating firebox.

Furnace starts and ignites and fan comes on but when thermostat is turned off the gas shuts off and flame off but furnace continues to run. whu?? any suggestions?

The fan normally runs for a few minutes or so after the gas shuts off.

This removes the heat from the furnace and transfers it into the living space instead of just letting it possibly cause overheating of the furnace until it dissipates. If it is a fan that blows outside, that fan also needs to run for a few minutes to clear exhaust gasses from the furnace - to keep them from dissipating into your home.

I have a dayton hanging furnace that after a few minutes the fan stops and burner keeps burning then a few minutes later the fan starts again and keeps repeating this cycle. model 3E845. thanks.

On the side of the heat exchanger is a fan Klixon that turns that motor on when the temp exceed 110f on the side of the heater. maybe that thang is going out or your fan motor needs oiling and is cutting out on overload. Next to the fan klixon is usually a limit. Both look the same. The fan klixon will have a marking stamped into the metal such as F-120 the limit will have L-240.

Williams wall furnace no longer adequately heats home

A couple thoughts. On some of the wall furnace gas valves there's a knob that you can set for low fire or high fire. If your valve has this make sure it is in the high fire setting. Is the wall furnace controlled by a wall thermostat or a knob on the heater? With the thermostat turned all the way up like to 90, does the burner and fan continue to run or is the burner short cycling. Is the fan clean and running up to speed. Some of the Williams wall furnace had a two speed fan motor so when the fan came on at first it would run on low speed. As the heat exchanger got hotter the internal fan switch would switch it to high speed. Outside of that you would need a monometer to check the manifold gas pressure.
