I have an old upflow gas furnance- aladdin brand trying to repair

So, the blower works but burners don't fire up? Does it have pilot lights, are they burning? Is there any gas smell? What sort of controls does it have - I'm not familiar with Aladdin gas furnaces and could not find any info whatsoever. Actually makes me think that maybe Aladdin is not the manufacturer's name but rather a service company nameplate on someone else's furnace. On a pretty careful search no Aladdin gas furnace manufacturer comes up but pretty much every state out there has at least one "Aladdin Heating Company" or a similar named company, hence the suggestion. I've seen "Aladdin" ceramic electric heaters and kerosene lamps, but not gas furnaces.

In any event, problems with ignition on a gas furnace are much  better left for professionals to handle. Small problems with gas can lead to spectacular but catastrophic results. Please consider calling a service company in the area.

The pilot is lit and burning. no gas smell. Not sure if burners fire up?? Aladdin is the name on the plate covering the pilot access and burner area??  Will have to check again to see if there is another name on the furnace

the pilot is lit and burning. no gas smell. Not sure about the burners. They do not appear to fire up so I'm not sure if that is a blower problem.  Other than the gas valves and pilot switch there aren't that many controls on the furnance

 So neither burners nor blower are working then, right? Is there a thermostat? Does the furnace make any noise/sound whatsoever when the temperature goes below the set level?

 Not sure how to tell if blowers or burners are working. right now the pilot light is burning. there is a thermostat that clicks when you set it above the current temp but not sure that it is relaying to the furnance.  It is warm now so hard to crank up the heat on the furnance. 

 The blower is the motor that distributes the heated air around the house. It would be hard to miss if it stops working - the air stops flowing from the vents. Have you tried to check the most obvious - the circuit breaker for the furnace? Can you turn the blower on without the heat on - the "Fan" control setting if you have one. If it turns on and cold air starts flowing, then the blower is not the problem. If it does not - check the circuit breakers first.

The burners produce a distinct sound of burning gas which is also hard to miss, so if you don't hear that, it can be a problem with the thermocouple - the sensor that checks if the pilot light is lit. If it isn't (or the thermocouple is damaged and it <strong>thinks</strong> it isn't when it actually is), the gas control valve would not open - a safety feature.  There can also be a problem with the gas valve itself.

With these last two  possible issues, we are again getting into a gas safety-related territory that makes me say again that a pro needs to look at it.

I was having similar problems last winter. I gave up on trying to figure it out myself so I went looking for professional <a href="

Always an important consideration. This factor is usually determined by other factors as well.
