I have a 4 tap kegerator that I keep in my garage. Over the last few weeks my taps have been freezing on and off due to the extremely low temps around me. On the days that my taps are thawed, 3 work fine but one continues to pour entire glasses of foam. I've tried filling one glass with foam and then trying again and each time the same result. All 4 taps are hooked up to the same co2 tank. Any explanation for this?
