A/C Update - Mobile tech came out today and checked amperage draw on the front unit and it was a little over 9. He said when it is working hard it will draw a little over 12. He measured the vent temp with a probe hooked up to his multimeter. I knew something was off as it measured ambient temp at 55.4 degrees and it was 74 in the coach. That said, it measured the cold air at 28.8 degrees, close to a 30 degree difference.
My infrared measured 74 ambient and 44 at the vent so they agreed more or less. Still no explanation as to why a 15,000 BTU unit can’t get the coach below 85 when it’s 88 outside. I’ve ordered reflective screens for the front window so we’ll see what difference they make, if any.
The tech they sent knew nothing about how to rewire the furnace controls so I will be getting another visit from someone who knows something and during the week so they can contact Tiffin. I looked at the panel in the front drivers side bay and nothing was marked “furnace”.
