Why does frost form on the evaporator coil of my Dometic 459516 Air Conditioner?
- SStacy ScottSep 12, 2025
Frost can form on the evaporator coil of your Dometic Air Conditioner if the product is producing very cold output at a very low air speed or if the outside temperature is relatively low. Inspect and clean the filter. Open the air vents and remove any obstructions. Adjust the thermostat control knob to a warmer setting (counterclockwise). You can also operate the product on any Fan Only setting until the coil is free of frost.
