What is the 120 volt switch under the sink used for Been camping now for 15 days and found nothing that doesn't work as I have let it in the off position?
Can you post a pic so we can see the style of switch and its location?
Standard 120volt switch like in your house. HD blue plastic box /plastic plate surface mounted. 12/2 Romex running to it. under sink. Rear kitchen left side door.
Electric water heater. Are you using it in gas mode?
Single mode. Gas only, 6 gal. 12,000 btu. Seems A/C is for ignitor. Ignitor reset on the front of the cabinet next to sink. I just didn't know it wasn't working when I had the switch off. All is good now.
