First: Atwood, unlike their primary competitor, uses a single set of thermostats for both Gas and Electric, SO, if it gets hot enough on gas we know they are working and have eliminated them as the suspect.
This leaves only the electric side of the heater.. This consists of the following.
The Control board (Common to both sides) might have an issue.. There is a relay, the heat element, the wires and the circuit breaker.
Suspects include:
Bad connection(s)
One of the circuit breakers in my RV, back when it was new, Well I had power issues (A/C's working when they felt like it... I found one of the breakers had a screw that took over TWO FULL TURNS before I felt resistance to farther tightening, Several in that area took additional tightening... This was causing an intermittent connection.
The wire then runs to the RELAY box.. Again we have connections, and the relay itself Always a suspect
Incorrect.......Atwood didn't go to one set of t-stats until 2004.
Prior to that electric has it's own 110V set of t-stats and propane has it's own 12V DC set of t-stats.
Electric is direct 110V AC from circuit breaker to switch to t-stats to element.
The Relay didn't happen until 2004 when DC was used for both electric & propane functions. The relay triggered the 110V to element.
No circuit board either for electric.
OP has a 1999 year model......not 2004 plus. SO it isn't the same.
