Gas ducted central heater won't switch on all of a sudden

Vulcan AUW230A... | Answered on Oct 02, 2011

Hello there,
First why not try to work on the fan. Have it disassembled, cleaned and then grease the ball that rotates the fan. It should work regularly that way.
Yes, there are replacement fan unit for the device but i will advice you get a replacement oil heater. DeLonghi have one of the best type of oil heater that can fit in to replace the Vulcan oil heater.
You can find it in the above link.
Hope this helps. Goodluck Elect_Comp

You can use a hacked up central filter.

When the fan of your heater does not turn on and the igniter lights but then goes off, then it means there is a problem with the unit of the machine.

The problem with the furnace is that the element of the furnace is bad and need to be replaced. Also check the relay switch of the furnace, that way you will be able to fix both the fans problem and the ignitors also.

Hope this was helpful to you.

if the glass is sooty then cleaning it will not solve the problem , its not burning right causing the soot , needs to be serviced by a gas fitter.

hello deb.... your best solution is to call your gas provider. they have a free service whereby they come to your home and do a safety check of your heater. then they instruct you on the best way to light it etc. Joe

If the fuse is blowing and reblowing after new fuse, measn that you have some short circuit in your system. I suggest check wire connections and device components to secure that problem.

Keep us updated.

I assume the heater has been installed for a year or more therefore, F1is the fault number O4 is the fault code and this 04 means the auto over temp has been tripped due to poor airflow through the heater. (the rear of the heater is getting above 65 deg C)

Check all outlets and remove any filter in the outlets.

Remove the return air filter clean if fitted.

On 4 & 5 star heaters check fan speeds are set correctly on control, low fan 27 to 30 and high fan 35. (download customer manual from climate technologies website) 70% of outlets capacity must be open at any time.

Check if the ductwork has been obstructed in any way.

Have the room fan checked and the auto high limit changed by a qualified person. Have a Carbon monoxide test done every 2 years.

Check if there is contact between the terminals of the thermostat using an ohm meter when set to a higher temp, if the reading is infinite or open, you have to replace the thermostat. Also check if the thermopile is receiving enough heat from pilot flame for it will generate a little amount of electricity to energize the main valve and fire up the burner.

Vulcan Heating &... | Answered on May 15, 2011

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
