Ture Blue furnace model USA 054 NH3R from Consolidated Industries.
Problem is I don't seem to be getting gas to the smart valve ignitor assembly, I replace the orfice in the assembly because the flame I was getting was too much (had been opened to large from trying to clean) I re-assembled and had a good flame and then re-installed into the burner chamber but could not get the chamber to ignite. Tripping the furnace off I tried again and could not get a pilot assembly to re-ignite so I pulled it back apart and now It seems to have the problem of not getting propane to the electric ignitor. Is there a reset switch that may be the problem? Please help
Cold in Michigan!

The gas valve on most models not only supply gas for the main burner but also supply gas for the pilot. If you disconnect the aluminum tube for the pilot where it exits the gas valve and push the pilot button or lever there should be a small stream of propane gas present. If not you are out of gas or the valve is probably defective.

It is also common for a new pilot orifice to plug up especially if there was debris in the aluminum tube from before so you might also check that again.

NOTE: Propane is a unforgiving gas. It puddles since it is heavier than air and can cause quite a problem if uncontroled ignition takes place if you know what I mean.

Check for pilot gas a valve first since that is easiest then check the pilot orifice and tube for debris again.
