    Liebert Minimate Plus

    I had walked past the condensing unit for this set up for 10 years and never gave it a second glance until 2 weeks ago. We traced out the refer lines an found the evaporator unit in the drop ceiling. No one had any idea it was there. Once I began troubleshooting the unit, I have 208V coming into the unit, 24V out of the transformer and into the circuit board, but no voltage anywhere else on the board. I pulled the board and see no signs of damage. I am thinking it is a bad circuit board? Any one have any insight on what I might be overlooking? This is the first time I have worked on a unit like this.

    Turns out to be a loose connection on the circuit board and 4 wires disconnected from the room temperature sensor. Made all the connections correctly and this unit ran for the first time in at least 10 years.
