Hi everyone, I would really appreciate some input from you knowledgable people.
Ive got a tiny house (ok not quite an RV) that Ive been building and I put an Atwood OD-50 on demand LP water heater off of Amazon in it. It came with three wires sticking out, a red (hot), blue (lockout lamp, optional) and green (ground). It wants 12v DC power but my tiny house is wired AC and plugged into a 15amp extension chord. So I went down to the local RV repair spot and they suggested getting a little AC adapter. Input 1.8 amps, output 12v 5amps. They told me to snip the DC plug off and get a switch, then wire the positives from the heater and the DC converter to the switch, and wire the ground from the heater and the DC converter to a ground wire that I ran to my chassis. I also ran two ground wires from my AC box, one to the chassis and one to a grounding rod.
Now when I fired up the hot water heater and flipped that switch, it started humming and trying to ignite before I even turned the water on. I turned the water on and it fired up. I turned the switch off to see what would happen and it turned off. Ever since then no matter what I do it wont fire. That humming sounded weird to me, and I dont hear that anymore either- though I suppose it couldve been the vent fan. There is still a very faint clicking when I run the water through it but it does not sound like an igniter to me.
Any ideas? Have I messed something up here?
Thanks so much guys!
