HOT WATER TANK CONTROL

Anyone tried leaving the little cover off the T-stat, if its getting too hot? I don't know why that wouldn't work.

Oops, chuck that idea, that would be going the wrong way,....sorry !!

Every Attwood I've had (3)is too hot @ 140 degrees ! And every one I have changed the T-stat to 120 deg. My current Suburban is not as hot, and is tolerable.
Seems like the OP could at least tell the name of the heater !
But at any rate, the dealer-Mfg is correct, there is no adjustment on our normal Att-Sub heaters, but I do understand there is an adjustable T-stat available.

For Suburban ?

There are aftermarket adjustable thermostats available.

Suburban (non pilot) have pre-set t-stats. 1 set for electric and 1 set for propane
Optional normal t-stats are available in pre-set 120*F or 140*F (Standard is 130*F) 120*F is harder to find.
NO adjustable t-stat option

Atwood (non pilot) have pre-set t-stats (Since 2004 just 1 set for both electric/propane)
Optional normal t-stats are available in pre-set 120*F (Standard is 140*F)
An Adjustable T-stat is available 110*F to 150*F

I have never had a adjustable. IMHO too hot is better sinc you have to mix in cold water the hot last longer which is a good thing since a 6 to 10 gal tank is so much smaller than a 40 to 50 gal like you probably have at home. :)

Some have an adjustment and some do not. I had an Atwood that had a temp knob but the suburban I have now is set and I would have to buy a new thermostat if I wanted it to be adjustable.

Moved from Forum Technical Support

Both Suburban and Atwood water heaters have 'factory preset' normal t-stat and high temp t-stat

Suburban.....
Normal t-stat set for 130F & High t-stat (ECO) set for 170*F or 180*F depending on model

Atwood.....
Normal t-stat set for 140*F and High t-stat (ECO) set fr 180*F


Pilot flame water heaters do have an adjustable temp control lever...usually 110*F to 150*F.

Which Brand & Model do you have?

Suburban SW6DE, SW10DE etc.
Atwood GC6A-8E, GC10A-8E etc.

Brand/Model number listed on data sheet in outside compartment....should be on trailer data sheet also


And if the Western RV Tech/Service Department didn't know/understand how your water heater functioned..........:S
I'd find another place for service. Water heater temp control is not complex.
