Alde 3010 worked only on shore power-problem SOLVED with new propane Regulator

Hi everyone, I bought a new to me 2014 CS-S last January. The Alde did not work and previous owner blamed fuses.  After reading all the helpful advice here, I  started by investigating fuses.  It ultimately came down to the soldered in Thermal fuse had blown.  After jumping around it, the unit came to life.  The pump would run, and it would do its thing when connected to shore power, but when I tried propane, it would go through the start sequence and throw an error after 3 tries. (original slider/switch analog controller)  So I checked the cook stove, seemed to be working properly, so I suspected not a gas issue.  I could hear the igniters clicking, smell gas out of the exhaust port, and even hear the gas valves click open.  I called Truma who were helpful and provided possible part numbers investigate including Fan, burner, Igniter, Main Circuit board.  I then called local dealer. who was helpful in providing prices for parts, but really wanted me to bring it in.  After waffling back and forth on what on what to do, I found a used 3010 on EBAY and thought worth a try...  After it arrived I swapped out (one at a time) all the parts mentioned above, and each time the same symptoms and errors occurred.  At this point, I went back to the forums and caught an unrelated thread that talked about failing propane regulators.  For 15 bucks and an adapter from ACE hardware,  I bought a propane gauge on Amazon  https://www.amazon.com/dp/B0C6KJ8865?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1   A pressure check revealed between 4-6 inches of water column with the old regulator (not enough)  A replacement regulator was ordered, and once installed, pressure checked out at 14 inches of water column.  I hooked everything back up and it worked!!!  In hindsight, I always thought the gas stove was a little weak, but since the camper was new to me, I had no baseline.  I wanted to put this out there as a PSA, the regulator cost under $50.00 and the other parts are WAY more than that.  In the conversations with experts and on-line research there was little mention of regulators as integrated part of the Alde system.  Trouble shooting says do the easy and cheap stuff first.  Next time it will be fuses, REGULATOR, then all the other wonderful spare parts I now own.
