I have this
switch configuration on my Bounder and this past weekend I got the dreaded red light, which indicates that the system has gone into faul and is locked out. Did some testing and determined that my "LOCKOUT" was due to the thermostat not shutting off the unit at the right temp. My elec and also tried it with gas, both raised the water temp to 150 degrees, at which time an overload shut down the system and emitted the RED LIGHT. By my testing it should shut off ~120 to 130 degrees.
I then ran out the scolding hot water, let it cool down then fired it back up on the electric mode and it worked great the rest of the weekend. So now the task it to try and figure out what is going on and what is failing?
Is it the TSTAT - Thermostat?
The brain box?
Or a once in a while deal that is normal with Camping?
