Spare Part Hot Box Control Expansion Board

Is the heating in your hot box working properly? If not you may need to change the expansion board. This board can fail due to a short in the system, power surge or burn out and will then cause the shelves to fail to heat. This is a cheaper alternative than replacing the whole hot box. A licensed technician is required to fit this part.

This expansion board plugs into the main control board and can heat another 5 shelves.
