6 red flashes, 2 green flashes — High heat-sink temperature

What does 62 mean?

The temperature inside the inverter's heat sink has exceeded its safe limit. The system will slow down to cool it, and if unsuccessful, the compressor and fan will stop. This can lead to a system lockout if it occurs repeatedly.

• Inverter heat sink temperature exceeded limit
• Loose screws holding the heat sink
• Poor contact between heat sink and control board
