My experience with my norcold after the green light blinking 3 times was this. Called Norcold and that was worthless. Took it the CW and they fixed it in 15 minutes and cost me $70 friggin dollars cause it was not a warranty issue. I has just filled my propane tank and apparently that introduced air into the gas lines. Here's the solution to save you guys money. When you store your coach for 2 weeks or more or fill your tanks before you do ANYTHING!!!! Light a burner on your gas stove and wait til the flame is a constant blue color. This is the best way to get the air out of the system since the burners are at the highest point. My fridge gas supply was interrupted and even when on shore power needs to see gas pressure or it will flash the code, " 3 green light flashes". Hope this helps so done out there!!!!
