Some times it will run 2-3 nights no problems. Then during the night when the unit is cycling on and off most often(as opposed to cooling continuously) the breaker for that unit in the electrical panel will trip.

  • why would my electric furnace have 2 breaker switches

    I actually see two potential issues here. When you say two breaker switches, do you mean two separate single-unit breaker switches? Or do you count a double-slot two-pole switch with a handle tie between the two switches as one unit and call it one switch? Either way, it is either rather unusual or simply wrong setup.
