"the pilot electro clicks and a moment later the fires come on and life is good.
Now I do all that but the fire doesn't come on, the pilot only tries for a minute and the unit shuts off leaving me with only a blinking greeen status light blinking.
My furnace in the rental was doing similar, and after sanding the heat sensor probe, it works happy. The Lochinavar has a thermo-coupler, "
Mixed info, the unit either has a sensor and electronic pilot module where the pilot lights ,
OR
a thermocouple where it stays on all the time.
Not both.
You might need to replace the contaminated sensor.
