I am going to purchase a gauge to check WC and pressure. Any recommendations?

Sooo, got the new part and pulled the cooktop. The new part was ordered because Dometic told me that the old part was defective and had been replaced by a new item. They sent a schematic of the original part and it is clearly different than the new part. Too, they indicated that the new part would be covered by warranty. Turns out that the new part and the part in the cooktop are the same. And the only way Dometic will apply a warranty is to have an official Dometic center declare the old part defective โ which, under the best of circumstances, is only possible at high elevation. As for Escape, the trailer manufacturer, appliances are warrantied by their manufacturers! They were of no help on an RV that is billed as high quality and only several months old. Why am I not surprised!

your instincts are corect in that atmospheric pressure plays a part but non of your calculations will work if you us 0 as a atmospheric pressure. it is 14.7psia or 101kPa at sea level and at 4500 feet it is aproximatly 12.5psia or 85.7kPa and 10 to 11" of watter colume is 0.36 to 0.4psi so realy at 4500 feet there should still be plenty of differential for it to work, maybe a slight yellowing at the tips of the flames. the problem with atmospheric relief regulators is they do use atmospheric pressure to act on the diaphram, the intent is to prevent an air lock from forming above it and preventing it from closing and it has a neglagable effect, but it is also much cheeper than using a pressure ballanced regulator set up.
myself I would remove the regulator , make a fitting to bridge the gap and try the stove, if it works put a new regulator in. mind you this might be more than you want to do while camping. the other option is to change it out and see how it works next time your camping.
this thread has me wondering if mine is starting to get week, I changed out my main regulator and everything got better but I do have a flame that is a little two yellow but I am under 1000 feet and even when I am at 4500-5000 feet it doesnt change realy, hmm something else to updte now I guess... thanks ๐
Thank you. You are correct, I forgot the 14.7 psi at sea level. Thanks to reminding me what I forgot....
no worries, I have been working with PSIa for 35 years now and I still have a momentary laps when I look at mormal pressur guages and try to plug the 0 into an equasion :B

There could also be oil in the line to the stovetop blocking the flow.
