SOURCE: weak flame in intertherm furnace

Ok, so we can rule out the ignitor. (standing pilot systems can develop problems that will cause such symptoms.)

Check the gas pressure, make sure you are getting 11 to 14 PSI.

You need that after the regulator all the way to the manifold.

Also check for cracks in the heat exchanger, causing the wind from the blower to distort the flame pattern enough to cause improper contact with the flame sensor.

Make sure the burners and flame channels are clean of rust, and dibri build up, allowing the flame to properly contact the sensors.

I would bleed the lines of air if the unit hasn't run for more than a few weeks.

If the flame starts up, but shuts down, a thermocouple or electric eye is erroneously not reading the flame, and it is shutting down for safety reasons.

If you would provide the model number I will look up more specific technical information, if you desire.

Good luck on this.

Brand New Ducane Furnace with Multiple Error Codes


Check your drain line. It appears that water is not draining and backing up into the furnace. Is there a drain trap? If not or if there is no vent on the drain line there can be a vacuum created when the furnace is running and it actually pulls water back into the furnace and when the inducer shuts off it releases the vacuum allowing the water to drain.
