1) I am having difficulty when looking at the electrical panel which breaker disconnects the power to the water heater. 1-6
2) Is it one of the breakers I switch off? If so, which one?
YES one of those 120VAC Circuit Breakers is for the WH Element. Element is 1440W and typically uses a 15A Circuit Breaker
3) Or do I pull one of the fuses? If so, which one? (one is marked "tank heater")
12VDC Fuse for 'tank heater' would be for heater pad on waste tanks OR could be for the 12VDC uses for LP Gas circuit on Water Heater
4) Is it absolutely necessary to disconnect the electrical power before I drain the tank and remove the old Anode Rod?
It is BEST to have the Individual 15A Circuit Breaker Open when WH Tank is drained.
If you can't properly ID which Circuit Breaker is for the water heater you can verify the AC On/Off Switch in outside compartment is OFF....Lower Left Corner behind/below gas valve
The handwriting on the panel is atrocious and at age 69 I don't want to create problems for myself by being impatient.
This is my first RV, 1 year now, bought used 5/21 and am working my way thru a list of stuff to check and make sure it is in good shape.
And yes, I have read the Manual and instructions from Suburban for the model SW6D Water Heater. Checked also on YouTube.
Voltmeter.....remove the 'Push To Reset Cover above gas valve
Under that cover are 2 sets of t-stats
120VAC...Left side Black Wire
12VDC ...Right Side Red Wire
Turn WH on using AC....verify you have 120VAC at the Left set
Then Have someone open each CB one at a time and ID which one drops AC to set of AC T-stats
Clearly relabel the CB.........
Turn on WH using LP...verify you have 12VDC at the right set
Have someone remove DC Fuses one at time and ID which fuse drops DC to set of LP T-stats
Clearly relabel the DC Fuse.....
