I have a P-R405B-EP and the flame roll-out switch went off. I by- passed the switch briefly to see what the problem is. The switch worked for good reason. Ther are some flames coming from the bottom left of the unit that came up right where the switch is (nice placement). A little flame was also coming out from the lower left also, thus threatening to burn he wires there. I closed down the unit and shut off the gas. Can you tell me what might be causing the flame to roll out and how I might fix it? Thanks, Jim

Thank you for posting your question here on Fixya.com.

Spiders have been in the burner tubes and there is enough silk in there to prevent the gas flow down the tube. I use a stiff piece of #8 wire to run up inside the tube to clear out the silk.

Along the bottom edge where it slips over the jet you should see a little dip and opening from below the gas manifold. Run the wire up into the burner from there. If there is a lot or a few passes doesn't clear it out I bend a little hook into the tip of the wire. After a few more passes it should clean it all out and the burner tunes should work properly. Confirm this by checking all the flames to ensure they are solid blue and a few inches tall off the burners.
