I have a Bard furnace with Honeywell controls and propane gas. All electronic components working: Thermostat calls for heat, inducer starts, 24v from S8610U control sends 24v to VR8345M pilot valve, good spark at pilot burner/igniter-sensor but pilot will not light 95-100% of the time. I used manometer to check house gas pressure, inlet pressure at the pilot valve - and even turned on all of gas stove's burners to ensure that gas pressure at the pilot valve still maintained pressure; and it did at 12" water column. Had local contractor come yesterday to assess the problem. I was concerned about the 13 year old gas valve. He could not find anything else wrong and suggested that the gas valve might be weak and not opening the pilot gas enough, so he changed it out. No change, still not working right. We know there is gas since while the spark is initiated since we can consistently manually light the pilot with a match. We made all kinds of adjustments (up and down) to the pilot flame after initial adjustment to spec. Once lit manually, the main valve will open and the furnace works to get up to heat setting. After shutdown, the next call for heat still will not work. So all of that leads me right back to the Q345A (igniter) spark and gas area. The spark is strong. Is there ever a need to bend the flares of the Q345A in order to try to divert the pilot gas flow closer to the center, where the spark is? Honeywell will not offer any advice on whether or not one of their other igniter/sensors (Q348, Q373, Q362) are comparable. They each have a slightly different design at the hood area. I am hopeful that you all can help with this - and Thank You.

My furnace is acting as if it has a bad flame sensor, I tried cleaning it but that didn't seem to make a difference. The pilot on my water heater keeps going out. I can relight it but eventually it just goes out again. Just seems weird that they stopped working at the same time.
