Suburban Water Heater not Heating

[rtate]

My Suburban water quit working on 120 volt but works fine on gas. I checked the voltage where it connects to the heater element and get 120 volts..

Anyone know what the resistance should be? Anything else I should check before I replace the element?

IF 120V AC voltage is measured at element as in the OPs case the set of t-stats are good......if bad no AC voltage to element.

Testing for and finding 120V AC at element means AC circuit is good.....from CB to On/OFF switch to set of t-stats to element.

Test for resistance....across the two terminals there should be continuity and then check each terminal to the body there should not be continiuity (a short to ground).
If you have high resistance then element is bad



That is one nice feature with Suburban....independent heating functions
Atwood combined functions 10 yrs. ago. Same circuit board and same set of t-stats

You'll need the wrench to change it. Available at Lowes or HD. This video helped me the first time I changed an element.

I think you are correct. I just ordered a new one for $12 delivered to my door.

This post talks about that.
