Refrigerator no longer works on Propane -- Need Advice

Sorry to hear your troubles with fridge on LP mode. I just posted in tech part this forum. Was having same trouble as you. New Regulator was the answer for me. You will have to get propane system checked at a shop or buy a manometer and you can do it yourself. Plenty of videos online to show how to test the pressure. I will be buying one to add to my tool box. Good luck.
