Because I had propane and because I had not exposed the heater to rain, I knew I had an electrical problem when my heater wouldnít kick on. No fuses in the panel schematic so I went searching. Found a rocker reset switch UNDER the blade insertion - see pictures taken after removing the outer panel. Rocked it off, then reset and voila! Heater working! Yay! Easy fix. Just wanted to pass this on. You guys have always been so helpful.
