The reason you have a on/off switch for the electric heating circuit on the cover on backside of WH Tank is because that is OEM
*Electric on/off switch Inside is add on by RV MFG)
Your 2001 model has separate controls for electric and for propane
Propane OEM switch inside RV with a Fault Light
On backside of water heater under that cover is also where the 120V AC set of T-stats are installed for the electric heating element which is installed there also.
T-stat Opens at 140*F.......ECO/Hi T-stat Opens at 180*F (trips)
In outside compartment is the circuit bd and set of 12V DC t-stats for the propane controls
T-stat and ECO/Hi T-stat ....same temp settings as electric
Should also be a 'thermal fuse' (brown wire from circuit bd ---clear tubing---connects to t-stat) It Blows at 190*F (flare back of flame) and has to be replaced
Post actual model number IE: GC10A-3E Or GC6AA-8E etc if you would like wiring diagram, info etc
Is it time for YOUR Medication or Mine?
