A hum with no display usually means the fridge is getting AC power (the hum is often the AC heater relay or transformer), but the control side has no 12V. Check the 12V DC at the board, the fuses on the board and at your RV fuse panel, and the polarity. See our won't turn on checklist. Send us your model number if you need parts.
