Customer complaint
What the customer noticed
The air conditioner stopped working at the campground.
Diagnostic findings
What inspection and testing revealed
The Coleman thermostat had failed and needed replacement. Inspection also found heavy dog hair, dust, dirt and nicotine odor inside the AC; that buildup was not the cause of the thermostat failure.
Work performed or recommended
What Sunset did or recommended
Diagnosed the failed thermostat and documented the need for thermostat replacement and AC cleaning/maintenance.
Outcome and next step
Where the service call stands
The source post does not confirm a thermostat replacement or cleaning during this visit, so those remain recommended follow-up work.
