Warm Air Heating Suddenly Stopped

[aswpleae]

My knowledge of heating is somewhat limited...our old warm air heating - no idea of make of boiler / fan etc, but installed with the house in the '70s - stopped working yesterday. I've tried to 'spark' it with the button inside but nothing's happening. The timer still works, it still 'clanks' on - which I've now worked out is the sound of the spark (I'm sorry I can't think of the proper word!) but then nothing else. THere seems to be gas or air going in when I hold that button as there's a 'wheeze' of sound.

So, I'm guessing it's going to be, either, the fan? (I couldn't even tell you if there is one, but I've reading around and assume there has to be one!) Or the spark - but I don't know enough about either to make a guess. I would also presume that one is pretty expensive and the other not so bad??

ANy help, at all, appreciated - this may even go beyond my dad's expertise!

Has it ever been serviced??

I would suggest you get a tame RGI with a warm air ticket to sort it, unless your dad has one,which I doubt.
Please don't mess with it, old ones can be dangerous

get it checked out by a RGI, WAHs or nearly always open flue and need servicing yearly, also sounds like you have a gas/safety device related problem

From what i can gather from your post are you saying the pilot light has gone out?

If so the majority of warm air units dont have a sparker or auto ignition and require a long match / taper to relight it. If the pilot is lit and its clunking but not firing then the gas valve has likely failed and requires an RGI to replace.

The fan is probably ok, they dont kick in until they heater has got hot so they dont circulate cold air. You can chck the fan by switching the timer to summer air flow.
