Dometic Brisk AC frost on cooling coil

Use this when a Dometic Brisk air conditioner shows frost or ice on the cooling coil with very cold output and low air speed.

Owner-safe checklist

• Inspect the owner-accessible filter and clean it if dirty.
• Make sure supply vents are open and not obstructed.
• Set the thermostat warmer if outside temperature is relatively low.
• Run any fan-only setting until the cooling coil is free of frost, then resume normal operation.
• If frost continues, stop cooling and contact qualified RV HVAC service.
