Beacon 1 from heatcraft acting like it’s gone mad.

Is anyone familiar with the original beacon systems from Heatcraft? I have only dealt with Beacon 2 and the newer QRC systems.

This unit is on a freezer with one condensing unit and two evaporators (one master and one slave). The other day it decided that it would go into random defrost cycles, and sometimes just shut off. All the sensors ohm out just fine on the evaporators and the condensing unit. The system is set for demand defrost. Yesterday the unit functioned fine but would shut down around 10F even though it’s set at 0F on the remote control head. The condensing unit is running fine, but the brains are just going nuts. I’m at a loss besides just upgrading the controls to a QRC and being done with it.

Thanks in advanced for any help. And happy 4th to the Americans.
