I know the system well. We have a wall AC and window AC. We have a sunny room that gets hot and since we heat with wood, it gets cold too so we close it off from us as needed.
Keep in mind though that hanging peppers to dry works really well in Mexico and the SW USA. Temperate climates, not as well. You can get a cheapo hygrometer from walmart to know the humidity of different spots in the house. I think I paid $8 or something.
I can't get it lower than 60-65% in here this year but this year is not normal. We also don't have a tight house. I've never monitored the sunny room.
Above the fridge would be a good spot but for most people, that's a cleaning project first. :) People have dried and cured things in their attics forever.
We have a Bosch Duel Fuel range that I can set to 100 for bake or convect bake. I’ll start them on the sunporch until they’re mostly dry. No point in burning our eyes out on released pepper fumes.
We learned that when I dehydrated some garlic.

Westphalian Ham hung to cure (cold smoked) in every German fireplace chimney all Fall and Winter when my Great Grandpa was a kid. :)
