If your Dometic Air Conditioner doesn't turn on, it could be due to an activated circuit breaker. Try resetting it. Alternatively, a blown fuse might be the cause, in which case you should replace the fuse.
Why is my Dometic FreshJet 3 not maintaining temperature?
If your Dometic Air Conditioner struggles to maintain the desired temperature, consider that the RV's heat gain from high outdoor temperatures or humidity could be the cause. Try parking the RV in a shaded area. Also, use window shades, blinds, or curtains and keep the windows and doors closed or minimize their use. It is also recommended to avoid using heat-producing appliances inside the RV. For better performance, operate the product in the Turbo Fan/Cool mode and start the product before the outside temperature increases.
What to do if frost forms on the evaporator coil of my Dometic Air Conditioner?
If you notice frost forming on the evaporator coil of your Dometic Air Conditioner, it might be due to very cold output at a very low air speed or the outside temperature being relatively low. First, inspect and clean the filter. Then, open the air vents and remove any obstructions. Also, adjust the temperature to a warmer setting. Finally, operate the product on any Fan Only setting until the coil is free of frost.
How to prevent condensation with my Dometic FreshJet 3 Air Conditioner?
If condensation forms on surfaces when your Dometic Air Conditioner is running, it's likely due to water vapor in the air being below the surface's dew point. To reduce condensation, keep doors and windows closed while the unit is operating.
What to do if Dometic Air Conditioner does not operate when connected to land line?
If your Dometic Air Conditioner isn't working well when connected to a land line, the RV might not be receiving power. Ensure the land line is properly plugged into the power supply and is adequately sized for the product’s power load.
Why Dometic Air Conditioner doesn't work when connected to motor generator?
If your Dometic Air Conditioner isn't working well when connected to a motor generator, confirm that the motor generator is running and producing power. Also, confirm the fuse or circuit breaker is open. Ensure the fuse is not blown, or the circuit breaker is on and not activated.

The Dometic FreshJet 3 and 4 Series Rooftop Air Conditioner, including its Air Distribution Box (ADB) and Electronic Controls, is designed for installation on the roof of Recreational Vehicles (RVs) to provide climate control. This product functions as a two-component system: a rooftop unit and an internal air distribution box. It is intended for use during or after the RV's manufacturing process, ensuring proper climate management within the vehicle.
The FreshJet Rooftop Air Conditioner's primary function is to regulate the internal temperature of an RV through various operating modes. It offers cooling, heating (if equipped with a heat pump), and ventilation capabilities. The system is controlled via an electronic control panel located on the air outlet of the ADB cover, allowing users to select desired modes and temperature settings.
The core operational modes include:
The control panel features intuitive icons for easy operation. Users can adjust the temperature setpoint using the (+/-) icons, with the LED display showing the current setting. The brightness of icons indicates their status: 100% for selected/active, 50% for unselected/available.
Regular maintenance is crucial for optimal performance and longevity of the FreshJet system.
The manual emphasizes the importance of proper installation and adherence to safety warnings to prevent injury, product damage, or property damage. It also highlights that modifications to the product are extremely hazardous and that service should only be performed by a qualified person using Dometic-approved replacement parts.
