If your Dometic Air Conditioner isn't working, it could be due to a tripped circuit breaker or a blown fuse. Try resetting the circuit breaker. If that doesn't work, replace the fuse.
Why is my Dometic Air Conditioner not cooling properly?
If your Dometic Air Conditioner isn't maintaining the desired temperature, it might be affected by the RV's heat gain from high outdoor temperatures or humidity. Try parking the RV in a shaded area, using window shades or curtains, keeping windows and doors closed, avoiding using heat-producing appliances, operating the product in the Turbo Fan/Cool mode, and starting the product before the outside temperature increases.
Why is my Dometic FreshJet3 Air Conditioner not working when connected to land line power?
If your Dometic Air Conditioner isn't working well when connected to a land line, the RV might not be receiving power. First, confirm the land line is plugged into the power supply and is properly sized for the product’s power load.
What to check if my Dometic FreshJet3 isn't working on generator power?
If your Dometic Air Conditioner isn't operating correctly when the RV is connected to a motor generator, it may not be receiving power. Make sure the motor generator is running and producing power. Also, check the fuse or circuit breaker to ensure it is not blown or activated.
What to do if frost forms on the evaporator coil of my Dometic FreshJet3 Air Conditioner?
If you notice frost forming on the evaporator coil of your Dometic Air Conditioner, it could be due to very cold output at a low air speed or low outside temperature. First, inspect and clean the filter. Then, open the air vents and remove any obstructions. Also, adjust the thermostat to a warmer setting. You can also operate the product on any Fan Only setting until the coil is free of frost.
How to prevent condensation with my Dometic Air Conditioner?
To reduce condensation forming on surfaces when using your Dometic Air Conditioner, keep doors and windows closed while the unit is running. This minimizes water vapor in the air that can condense on cooler surfaces.

This document serves as an installation manual for the Dometic FreshJet3 and FreshJet4 Series Rooftop Air Conditioner, which includes an Air Distribution Box (ADB) and Wall Thermostat Controls. The product is designed for installation on the roof of a Recreational Vehicle (RV) and comprises three main components: the rooftop component, the internal air distribution box (ADB) component, and the wall thermostat. It is intended for use in RVs during or after manufacturing, ensuring proper climate control within the vehicle.
The Dometic FreshJet Rooftop Air Conditioner is a climate control system designed to provide cooling and, in some models, heating for recreational vehicles. The system operates by drawing in air, conditioning it, and then distributing it throughout the RV via the Air Distribution Box. The wall thermostat serves as the primary interface for users to control the unit's functions, including setting desired temperatures, selecting operating modes (Auto, Cool, Fan, Heat), and managing fan speeds. For models equipped with a heat pump, the system can also provide heating. The electronic control box, located within the ADB, manages the various functions of the unit based on user input from the thermostat and readings from sensors. The system is designed to integrate with the RV's electrical system, requiring both 115 VAC and 12 VDC power supplies. Certain models may also support integration with an RV-C bus system for multiplexed control, allowing for more advanced management of multiple air conditioning units or other RV systems. Optional features, such as an indoor temperature sensor, can enhance the system's ability to maintain a comfortable RV temperature by providing more accurate readings. The system also supports an optional load shed feature, which can be integrated with an Energy Management System (EMS) to manage power consumption, particularly when operating on limited power sources like generators. Additionally, for RVs equipped with an automatic generator start (AGS) feature, the system can be configured to interact with it via RV-C communication.
The Dometic FreshJet system offers a range of features to ensure a comfortable environment within the RV. Users can select from various operating modes, including Auto, Cool, Fan, and Heat (if equipped with a heat pump or furnace connection). The thermostat allows for precise temperature control, enabling users to set their desired comfort level. The system is designed to be user-friendly, with clear controls on the wall thermostat. For installations with multiple rooftop components, the system supports multi-zone control, allowing different areas of the RV to be conditioned independently, provided an INC1015RD thermostat is used. The electronic control box includes DIP switches that allow for configuration based on the specific equipment options installed by the RV manufacturer, such as assigning zones, enabling furnace or heat strip functions, and configuring for specific communication protocols like RV-C. The system is designed to operate efficiently, with considerations for roof thickness during installation to ensure proper air distribution and sealing. The FreshJet4 series includes an LED light on the shroud, enhancing visibility, though it is not intended for use while the RV is in motion. The system also incorporates safety features, such as requiring proper grounding and adherence to electrical codes, to prevent electrical shock, fire, and explosion hazards.
Maintaining the Dometic FreshJet system is straightforward, focusing on ensuring optimal performance and longevity. A key maintenance task is the regular cleaning of the air filter. The return air filter, located behind the return air vent grille, should be removed periodically (at least every two weeks of operation) and washed with soap and warm water. It is crucial to allow the filter to dry completely before reinserting it, and the unit should never be operated without the filter in place to prevent dirt accumulation and performance degradation. The exterior shell of the Air Distribution Box (ADB) can be cleaned with a soft cloth dampened with a water and mild detergent solution; furniture polish or scouring powders should not be used. The blower motor within the rooftop component is factory-lubricated and does not require any additional servicing. The manual also provides troubleshooting guidance for common issues, such as the unit not operating, frost forming on the evaporator coil, or the system failing to maintain the desired temperature. These troubleshooting steps often involve checking circuit breakers, fuses, power supply connections, thermostat settings, and ensuring proper airflow. In cases where issues persist, contacting a qualified service person is recommended. Proper installation, as detailed in the manual, is also a critical aspect of maintenance, as incorrect assembly or connection can lead to unsatisfactory performance or failure.
