I have an Inter therm mod-055 gas atmospheric furnace Date Code 870825. Had the gas man refill the tank after change over to new tank gas regulator on tank to trailer. This was a gas code requirement Valve color Brown it is to have a pressure shut off. Ran 2-3 days know pilot will light when button down but goes out when released. I am thinking that have a bad therm o seducer. This all happened after change over to new pressure regulator.

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.

There should be a reset button in the upper chamer next to the fan motor. In the middle ,push in on the center red button to reset it, this tripps because it says I,m not gettig enough air flow due to a plugged or dirty fliter located on the front cover or door.
