Trion 220978-005 Contact Board Assembly. Replacement contact board assembly for electronic air cleaner. Each air cleaner contains 2 of these but they are sold individually. This item looks like a thin piece of circuit board with copper contacts attached to it. When installed, it is mounted on the bottom of the power supply box and electric wires are attached to the top of it. The bottom of this board has copper contacts on it and protrudes slightly into the path of the electronic collector cells. Over the course of time the contacts located on the bottom of this contact board assembly tend to get holes in them due to arcing of the high voltage power. This is a good indication that the contact board assembly needs replaced.
