Is there a temp adjustment on the electric/ LP water heater?

[Roger G]

On my 2014 36LA, the LP gas water heater heats great but when set to electric only, it only gets up to the low 90 range vs the cold water side in the low 70's. It doesn't get warm enough to shower but you can tell that it is heating some. It has been my experience that heating elements are either good or bad with no in between. A home water heater has a temp adjustment but I see none on the MH. Am I missing something?

Some RV water heaters have 2 thermostats for each heat source (one for overtemp and one for switching on heat)for gas and elect. under the insulation against the tank, some use only 2 'stats for both sources, but the insulation is what holds it against the tank. Often these will either vibrate or fall away from the tank, resulting in poor temperature control. None I've seen are adjustable, but they do come for different temperatures. I have read about an aftermarket adjustable 'stat.
To reach these, remove the access panel, gently pull the insulation apart to find the 'stats.
After you are finished, replace the insulation evenly, making sure the 'stats are firmly against the tank. since your water is only warm, I suspect a defective
stat.
