Water heater help
In my two-year-old fiver (Montana 3790RD) I have a Suburban electric/propane water heater that is acting up. So my questions are, at this point, what to troubleshoot. I have not yet look at the water ...

Electric element is under cover below/behind gas valve.
Check for loose wiring on terminals....black & white
Elements either work or don't work unless wiring/connections are loose
Suburban water heater has SEPARATE sets of t-stats for electric and propane.
Each set controls their own heating cycles
Electric uses a 120V AC set......normal/130*F (controlling t-stat) & high/170*F (backup/shuts down heating----needs to be manually reset)
Propane uses a 12V DC set......Same set up as electric
They are under the rubber cover above gas valve with 'Push to Reset'
So that the hi t-stat can be reset if it trips
Left side/electric
Right side/propane
If the electric hi t-stat was tripping YOU would have to manually reset it before electric would work again
Sounds more like normal has loose connections or not being held tight against tank wall
Open the 120V AC circuit breaker for WH electric element (or on/off switch OFF----but I don't trust them)
remove rubber cover and check wire terminal/spade connectors and if t-stat mounting is tight
Or buy new set and just replace it
NOW if you have a DEL model then electric uses a 12V DC relay to trigger electric element so that is another item to check on electric heating side.....ONLY ON DEL model
