  1. What happens when the coils are cooler than the boiler, but I already tested the AC element directly and the fridge operates flawlessly when directly wired. I’ve been tryign to figure this out for three weeks now. I’m starting to wonder if the injector is failing because the flame i have is there, but its nowere near the strength it used to be. It used to sound like an inferno when it was lit, now I can’t hear anything. Help!

  2. My Norcold N7LX.3F works fine on shore power but will not cool on propane mode, flame is burning just fine. I tried using a flex cam to look down the flue and I think it is clogged. should I be able to see daylight down through the flue? Best way to clean a plugged flue?

    Thanks!

  3. Freezer works fine, fridge not cooling, thermostat resistor on fins reads ohms. Boiler hot, coils not…. blockage? Even though freezer works? Vent is clear. High temp relay on the back, light not on.

  4. My temp on the pipes changes radically from 244 at the top of the boiler pipe to 118 just past that bend moving horizontally! The absorber is only 114…BTW, the freezer gets cold (after several hours on AC power) but the inside is only 58deg.

  5. I have a 12 volt cannon the freezer is working but fridge isn’t an the light keeps blinking please help
