It was great at cooling and freezing here in La Honda but it wouldn't freeze otter pops at Burning Man this year. Since I've got it out while repairing body work, I'll try the burp trick I've read about here in the forums.
But that's not my question. When lighting the LP, the procedure is to pull out and hold the orange knob and then spin the flint striker. It works but takes a number of efforts before the pilot (? - the blue light in the tiny window) stays lit.
1. Does anyone else have an RM45? I haven't been able to find a reference anywhere for this model. I followed a thread to a fridge repair link for manuals, but it didn't have the RM45. Is it common for the flame to take a while to stay on?
2. The flint/striker works but does not feel robust. Does anyone know how to change the flint or striker wheel? The older manuals I have found show access from the side of the fridge but mine doesn't have the same port.
A common problem with all RV reefers is the LPG burner.
Every 2 to 3 years, the burner should be removed and cleaned, along with the burner orifice.
The steel flue should also be cleaned by removing the spiral, then take a coat hanger and carefully add a piece of steel wool to the end. Then run the steel wool up and down the flue a number of times, until you see no further rust coming out of it.
under any circumstances, use a sharp object to clean the orifice.
The burner and orifice can be properly cleaned in a jewelry ultra sonic cleaner, leaving it run for about 15 to 20 minutes.
Or, you can soak them in some Limeaway for 3 to 4 days, then rinse them very well with water.
Also make sure the LPG pressure is between 11 to 13 inches of water column pressure, preferably 12 to 12.5 inches.
Finally, when you fire up the reefer, make super sure that it is not more than 1/2 bubble off level. Measure the level point inside the freezer compartment. If not, you can cause a "vapor lock".
When the trailer is in motion, if it's off level for a while, nothing will be hurt.
Hope this solves the problem for you.
