a/c issue

[Kellys]

While out camping our rooftop a/c unit ( coleman) started acting up I noticed that the low fan and low cool settings don’t function The other settings work fine then this morning the low fan and low cool settings started to work not sure whether its and issue of low voltage or the switch every thing else works fine

It’s either a bad switch on the t-stat or a faulty relay on the AC unit. I would lean towards a dirty or bad switch on the t-stat.

As Scott said sounds like time for a new Tstat, how old is your TT

It is 2006
