2014 Palomino Columbus Furnace 340RK
Took delivery of our 340RK 12.1 and have fought ongoing control issues with the suburban furnace. Furnace comes on, cycles through two or three cycles then stops coming back on. Power the unit off at the thermostat, it comes back on and heats through two or three more cycles. After changing the control board three times, Suburban authorized the repair tech to upgrade the board. Fourth board now installed and running great over the last week. Suburban admitted they have suffered through a bad batch of boards and replaced over 1000 units in the last six months. This is the only issue we have had, been in it every weekend.
