After heating with propane...........did you drain water heater and then refill it with cold water?
IF not....did you use all the hot water before trying the 'electric' side?
Water temp needs to go below ~110*F before t-stat will reset (close) to reheat the water.
Also if water heater is an Atwood it uses 12V DC power to ON/OFF switch and to relay inside electric cover to energize 110V AC power to electric element.
No 12V DC to switch/relay no AC to element.
To check for 110V at element:
Turn switch ON
Check for 110V using a voltmeter (touch one lead to black wire/terminal/touch other lead to white wire/terminal on head of element)
To check for continuity:
Turn switch OFF
Check for continuity between the two terminals on element........NO Continuity/element bad
Check for continuity between white wire/terminal on element to flange of element
There should NOT BE Continuity/element shorted
Is it time for your medication or mine?
