Changing the adjustment on any regulator is NOT a good idea, ever. As for the fridge, it's designed to run off the TT regulator, only. The heater isn't working right, because it's being double regulated. I believe they're designed to work with disposable bottles, or an unregulated hose to a larger tank.
Are your propane tanks full? What's the outside temperature? Propane contracts in the cold. When that happens, the liquid propane shrinks, and the tank loses pressure. Pressure too low, and the fridge won't light. If the propane tanks are low to start with, the problem is compounded by the low temperature.
