The FHTC123WA1 is the largest of the 115-volt FHTC wall units. At this capacity, electrical supply quality matters: a shared circuit or worn outlet can cause trips when the compressor starts.
An electrical or burning smell is a stop-now symptom. Turn the unit off, unplug it if the plug is safely reachable or switch off the breaker, and book service. Condensate overflow usually traces to a blocked drain path or sleeve pitch.
