That’s a good point, an obstructed orifice could result in the same symptoms as low LP pressure. Soak it in alcohol then blow it out to clean it, or just replace it.
It’s clearly an issue of not enough heat BTU’s are going into the cooling unit when running on LP, so the cooling unit performance is degraded. On mine, the flame produced with low LP pressure looks virtually the same as the flame produced with correct pressure. The only thing that’s noticeably different to me is the SOUND the flame makes. When the pressure is low, it’s almost silent. When the pressure is correct I can hear the flame without even removing the outside panel. I didn’t even realize that until I bought a manometer and adjusted the LP pressure myself. After adjusting it and hearing the flame, it was an “Oh yeah, I remember that sound now” moment for me.
And yes, get a wireless fridge thermometer that will let you monitor the fridge and freezer temps without opening the doors. My fridge, which is probably smaller than the average fridge because it’s in a truck camper, will cool down quite rapidly on AC or LP when it’s working right. When something is wrong, I can tell pretty quickly.
