Atwood water heater GCH10A 3E
Gas side has hot water. Electric stopped heating. Things done in this order: Breaker was not tripped and tests good. Switch tested good. The ECO side of ECO/T Stat was original, loose, looked worn out...

Do not get confused about 'relay'....your year model does not use that relay (relay didn't come about until 2004 and later models)
you have a direct 120V AC system with it's own ON/OFF switch (which is on cover over electric element in rear of WH) that goes to element.
AS stated in your post on 11/23/2014
Your year Atwood uses 120V AC power directly.......
From circuit breaker in AC panel to ON/OFF switch to/thru the set of t-stats and then to terminals on electric element (All located On rear of WH)
Check for AC power coming from circuit breaker (load side screw/wire)
WITH WATER HEATER FULL----With ON/OFF switch ON, check for AC power at terminals on normal t-stat.....then at terminals on ECO (high temp t-stat----should have a button to reset it if tripped).
Then at terminals on electric element.
Below are probable causes of no electric heating
Tripped CB
Bad On/OFF Switch
Bad set of t-stats (either one)
Bad element
Bad ground connections.
IF ECO has tripped.....then normal t-stat has failed and ECO shutdown heating.
IF water temp is over 130*F/140*F (depending on set point of t-stat) no heating (water needs to cool down below 110*F) before reheating cycle can occur.
Test for AC power first......hopefully you can ID issue without having to remove. But that depends on access.
Good luck!
