Central Control Unit heartbeat failure
From Tech Sheet W17949566, p.18:
1.Check for continuity of the User Interface harness.
2.Inspect the communication harness between the main control and the UI board for bent pins or unseated connectors at each end.
3.Measure supply voltage to the UI board. Expected: 5 VDC at the interface connector; a low or missing rail points back to the main control supply.
