Dometic RV Air Conditioner Troubleshooting
Let’s dive into 8 different ways of Dometic troubleshooting!
1. Examine The Duo Therm Thermostat
The first step when troubleshooting a household thermostat is to ensure the switch is in the ‘on’ position.
- With a multimeter, it’s possible to check the range of DC volts on the terminals – it should be more than 10 and less than 30.
- Resetting the system operation can indicate whether there are any wiring issues or problems with the thermostat itself.
- The device may not work properly if an error is indicated on the display screen.
A replacement may be necessary if the configuration is correct, but the problem persists.
2. The Unit Won’t Power On Or Stay Turned on
It can be frustrating when your RV air conditioner unit won’t turn on or stay on. One of the common problems that people face is that the AC unit either won’t start or will turn off after a few minutes of operation. If this is the case, there is likely an issue with the thermostat.
One way to troubleshoot this issue is by checking for a cracked solder joint in the on/off switch:
- This can be done by turning off the power of the AC unit, removing the panel cover, and examining the board for cracks or holes.
- If you find one, you will need to resolder the connection.
Another option is to use a voltmeter to measure the current values of RV ac on the socket:
- If the values are not as expected, then it is likely that a fuse needs to be replaced in the outlet.
- If this does not fix the problem, then it may be necessary to get the entire connection replaced.
- In rare cases, it may be necessary to get the wiring for your outlet replaced, and it is best to contact an electrician for this type of job.
3. Reset Your Thermostat By This Method To Stop Troubleshooting
If you are experiencing any issues with your Dometic Duo Therm RV air conditioners, one of the first steps you should take is to reset the thermostat. This can help resolve configuration errors, allowing the unit to work properly again.
To reset the thermostat:
- Begin by turning off the air conditioner and unplugging it.
- Then press and hold the down, up, and time buttons on the thermostat until the vents move. This process may take a few seconds and should result in the unit turning back on.
- After a while, the unit should be reset, and you can use it again as normal.
Note: It is important to remember that if you still have problems with the air conditioner, you may need to call a technician for further assistance.
4. Check Your Gas Pipe From the RV AC Unit For Leakage
Most problems with air conditioners are related to electrical or configuration errors. However, some people might run into a gas leakage with their unit, which can cause the unit only to pump out warm air.
If you experience this issue, it is recommended that you contact a reputable repair agency or Dometic directly to check the tank and fix the air leakage. If your device is still under warranty, contact the company directly for a free repair.
5. Poor Performance Of Push Buttons With Potential Solution
It is common to have the push buttons of your Dometic Duo Therm Air Conditioner not working properly. The major reason behind this problem is dust accumulation beneath the buttons.
To inspect the buttons:
- You will need to remove the top.
- Then press the tabs with a small flat screwdriver.
- You can also use spray contact cleaner to clean the contacts.
- After cleaning, the top should be turned on the switch to see if the push buttons are fixed.
- If not, it is recommended to call a professional for further assistance.
6. AC Cooling At The Wrong Temperature
It is possible that your Dometic Duo Therm air conditioner could be cooling at the wrong temperature. This could happen for several reasons, including an error with temperature sensing or a misalignment of the thermostat. It can be a complex issue, but attempting to fix it yourself is possible.
One of the important things to do when troubleshooting a Dometic Duo Therm RV air conditioner thermostat is to check the room temperature. To do this:
- Use a thermometer to determine the temperature in the room when the thermostat stops.
- Make sure to note down the temperature and compare it with the temperature set on the thermostat.
- The accuracy should be within ±3 degrees Fahrenheit.
If your Duo Therm RV air conditioner is not working correctly, turning off the thermostat first is important. To do this:
- Switch off the thermostat and turn on the AC. This will tell you if the issue lies with the thermostat or the AC itself.
- Turn off the AC after a while and switch on the thermostat again.
- Run a factory reset. Depending on your model, this could be done by pressing the reset button on the AC unit or by going into the settings menu and selecting ‘reset’.
- Solutions for different AC units vary depending on their type. For rear units, you may need to get a new upper board installed. Front units without a remote sensor should have one installed. Front units with a remote sensor should be checked with an ohmmeter and then find a replacement for the thermistor sensor and upper board.
- Lastly, make sure to clean and check the filter regularly to ensure your AC operates smoothly and efficiently.
7. To Fix The E1 Code On Duo Therm Thermostat
The E1 code on a Dometic RV air conditioner indicates poor communication between the power module boards and the CCC 2 thermostat. This lack of communication is displayed on the thermostat’s display screen. An additional zone may lose contact and blink right next to the original code, indicating that the unit has multiple zones.
To fix the E1 code, it’s necessary to do a reset system operation:
- This involves turning off all the breakers for the AC unit, resetting the circuit breaker, and then turning it back on.
- It’s also possible to resolve the issue by tracing the cable from the Duo therm thermostat to the air conditioner.
- If there are any kinks in the cable, they should be corrected.
- All loose connections should be tightened to restore communication.

Access the Connections
If you are experiencing an E1 code on your Dometic air conditioner thermostat, the first step is to access the connections:
- Make sure that all the connections are secure and none of them are loose.
- You should then disconnect the cable and reset the system.
- If a failure is detected in any system component, you may need to replace the thermostat.
- Once you have reconnected the cable, check if the issue is resolved. If not, further troubleshooting may be needed.
Do Not Void the Warranty
When troubleshooting a Dometic Duo Therm Air Conditioner, it is important to remember that accidentally breaking the thermostat or AC can void the warranty:
- If you notice any codes appear on the thermostat, it is best to contact an expert technician as soon as possible to ensure proper troubleshooting.
- This will also help to ensure that your warranty remains intact.
8. Replacing The Duo–Therm Thermostat
If you are replacing your Duo-Therm Thermostat, there are a few important things to remember. First, household thermostats generally run on batteries, while RV thermostats run on DC power. Secondly, both thermostats must have the same terminals when replacing the thermostat air conditioner units.
To begin replacing the Dometic Thermostat
- Turn off the rooftop AC power supply to the unit and begin the basic electrical work of disconnecting the wires from the old thermostat and attaching the new terminals.
- Be sure to label the wires and keep them from sliding into the pit in the wall.
- Please do not set up the new thermostat to work before testing all the appliances to ensure they work properly.
- If you need help with how to do this or are not comfortable doing any of the work yourself, it is always recommended to seek professional help.

The 4 Major Blowing Problems Duo Therm Brisk Air Conditioner
Here, you will read about the different issues related to Dometic therm brisk air.
Uncleaned Air Filter
A dirty filter can be one of the main causes of issues with your Dometic Brisk Air Blowing system. The filter for blowing cold air or hot air is responsible for capturing dust, dirt, and other debris from the air, so if the filter is clogged or dirty, it can restrict airflow and decrease air pressure.
To prevent this issue, it’s important to check the air filter regularly and clean or replace it as necessary. If the filter looks very dirty, it should be replaced rather than just cleaned, as it may be unable to filter out the debris properly.
Cleaning the filter is fairly simple:
- Only warm water and mild detergent are needed to remove dirt or debris.
- It’s also important to ensure the filter is completely dry before re-installing it in your Duo Therm Brisk Air Blowing system.
By taking these steps, you can help keep your Duo Therm Brisk Air Blowing system functioning properly.
Frozen Evaporator Coil
The frozen evaporator coil is one of the most common issues regarding the Duo Therm Brisk Air conditioning unit. It is part of the air conditioner responsible for cooling the air before it enters your home. This issue can cause a decrease in efficiency and an increase in energy bills.
Causes:
- Dirty air filter
- Low refrigerant levels
- Blocked drain line
- Obstructed cold air flow
Let’s take a look at some potential solutions to this issue.
- Clean the air filter: Cleaning the air filter will allow more air to flow freely and prevent the coil from freezing.
- Check refrigerant levels: Have a professional check your unit’s refrigerant levels and ensure they are optimal.
- Clear the drain line: Unclogging will help prevent any water backup that can cause freezing.
- Open all vents: Ensure all vents in your home are open to allow unobstructed airflow to the evaporator coil.
Air Duct Issues
Air ducts are an important part of your heating and cooling system and can be the source of many issues. Poorly designed or maintained air ducts can cause problems such as inadequate airflow, inefficient heating and cooling, and mold growth.
Here are some common air duct issues to watch out for:
- Leaks: Leaky air ducts can reduce the efficiency of your system and increase energy bills. Look for visible signs of damage, such as cracks, holes, and loose joints.
- Dirty air filters: Clogged filters can restrict airflow and reduce efficiency. Replace your blowing cold air filters regularly to keep your system running smoothly.
- Improperly installed ducts: Ensure all ducts are sealed properly and insulated when necessary.
- Inadequate insulation: Proper insulation is essential for maintaining a comfortable temperature in your home. Check for signs of inadequate insulation, such as condensation or frost on the exterior of ducts.
- Pest infestations: Insects and rodents can get into air ducts and cause health hazards and mechanical damage to the system. Check for signs of infestations and take appropriate steps to address them.
Problems With Blower
Blower issues can cause various problems with your Duo Therm Brisk Air unit. If the blower is not working correctly, it may lead to inadequate airflow, reducing your home’s cooling efficiency and comfort levels.
A faulty motor or fan belt is the most common cause of blower issues:
- If the motor fails, it can cause the blower to run erratically or not at all. This will result in reduced airflow and cooling inefficiency.
- A loose or worn fan belt can also prevent the blower from working properly. It should be checked regularly and replaced if necessary.
