I have a York stellar furnace (Model # p1udd12n07601a) and it will turn on the vent fan and the igniter the burners will light for a few seconds and then shut off . the vent fan continues to run, but then after 5 minutes the igniter starts glowing and it reignites. only to shut right back down. I have removed the flame sensor and cleaned it. checked the fusable link. any help would be greatly appreciated

Replacing the flame sensor won't fix your problem. Does your furnace have a circuit board? Does the gas valve have 24 volts across it as it drops out if so replace valve. If 24 volts drops out as flame drops out replace control board. Make sure rollout switches aren't opening.

There is no circuit board on my model. I removed the old flame sensor and cleaned it. It worked fine for a couple days then started acting up again. Do you know what terminals I test across to check the valve?

While working on my furnace I checked my drain hose for blockages. The plastic manifold that the combustion fan mounts to was cracked and leaking moisture. I cleaned it up and sealed with JB weld. Does anyone know the actual name of this part. So I can replace it.

Wuzzat?

How old must a furnace be to not have a control board?

Regarding your question in post #8.
If your refering to the plastic cover between the lower area of the heat exchanger and the inducer, (combustion fan). Then you are refering to the "collector box".
