I've got a problem that is getting the better of me so thought I'd reach out for some ideas if you have any.
The Scenario: The 2016 Bighorn (3750FL) was purchased new and delivered by the dealer to an RV park where my wife lives in it during the week while she's working away from home. It hasn't moved since. We have always used 110v for the water heater.
The Problem: Last week one morning, there was no hot water like there always has been. I began troubleshooting it by reading the documentation on this website and seeing what had worked for other people with similar issues. Not being skilled in the use of a multimeter, I went ahead and replaced the secondary on/off switch at the WH, the thermostat/hitemp switch and the heating element (boy, did it need it). Next weekend, I'm replacing the anode for the heck of it. It's cheap. Nothing so far has led to the 120v working yet so as to heat the water.
Today, I turned on both the 12v and 110v water heater switches in the master control panel and noticed for the first time that the light in the 120v switch is significantly dimmer than the 12v. My wife and I both remember them being the same brightness. I've attached a pic showing the two being on this morning. The camera is making the 120v switch brighter than I would say it really is. It was actually difficult to tell if it was on.
Could the very dim 120v light be indicative of a switch going bad with low or no voltage going to the WH? If so, any ideas on where to get a new switch? I have no idea where to get new switches that go in this panel. And if not, what the heck else could be problematic that I could look at?
Thanks for any help and Cheers!
