Control panel Switches

[Hawkpat]

Been in the road several weeks and yesterday the hot water switch (electric) lit as usual. When we checked at night it was off. Turned gas switch on and same thing. No light. Today while traveling turned water pump switch to on and no light and no pump. All of the rest of control panel switches (controlling lights) come on. The three switches are all next to one another in the 2012 3400 rl. Any ideas?

Check the 12 volt fuse in the breaker box. If they are ok then remove the panel and make sure the 12 volt going to those switches are ok. On my unit the 12 volts go to one switch and then is daisy chain to the others. If the connector has came loose then those 3 switches will not light and the pump and others will not work.

Dennis. Not sure I'm real clear but not great at electrical systems. There is one household type fuse labeled hot water. It seems okay. I switched it off then back on. There are a lot of 15 amp fuses above the household fuses and they are all good. I took cover off but could see no sign of any loose wires. Do any of these actions describe what you advised?

You did right by checking those 15 amp fuses to make sure there is no red light by them. If you have a voltmeter you need to check that household fuse labeled hot water. After that you need to see that you have 12 volts going to those 3 switches.
