Posting that I hopefully save someone some time and money. I was having a low flame on my stove and my fridge wasn't working correctly while on propane. So I just assumed it was the regulator. Replaced the auto switchover reg. Same problem.

Tried the water heater on propane and my furnace. Both worked correctly. Read where stoves have a regulator but that didn't make sense since my fridge was acting weird as well so the problem had to be somewhere in between.

Around the backside I went and there is a ball valve quick connect fitting that supplies my stove and fridge. I unscrewed it and oil started dripping out. That valve has a tiny pin hole and it was clogged with oil and who knows what else. Shot some air through it from my compressor, reassembled and everything is working as it should. And now I guess I have a spare regulator..

Hope this helps someone down the road.
