To maintain comfort in your Bürstner, a functioning air conditioning system is essential. If it no longer cools as expected, you can take initial measures yourself before seeking professional help.
Possible causes at a glance
- Electrical problems: Missing 230 V shore power supply or a tripped residual current circuit breaker can impair the cooling function.
- Hiring matters: Wrong mode or unfavourable target temperature can reduce the cooling capacity.
- Maintenance and blockages: Dirty air filters, clogged condensation drain hoses or blockages on the outdoor units disrupt air circulation.
- Remote control problems: No batteries or dead batteries in the remote control can prevent you from setting the correct mode.
Solution approaches
- Ensure power supply (check RCD switch): Check whether the air conditioning is supplied with power at all. Check whether the residual current circuit breaker (RCCB) has tripped and reset it if necessary.
- Activate cooling mode (e.g. for Dometic FreshJet): Make sure that the air conditioning is running in the correct mode. The cooling mode is often inadvertently deactivated or another mode, such as fan mode, is selected.
- Set target temperature below room or outdoor temperature: Check the set target temperature. It should be lower than the current room or outdoor temperature so that the air conditioning can work efficiently.
- Clean or replace the air filter according to the instructions: Dirty air filters impair air circulation and reduce cooling capacity. Clean or replace the filters regularly to ensure optimum air circulation.
- Check the condensation drain for blockages: Check the condensation drain hose for blockages that could obstruct the water drainage and thus reduce the air conditioning power. The hose should be cleaned in the event of blockages. Always follow the manufacturer's instructions in the operating instructions
- Check roof components for loose parts or blockages: Regular visual inspections of the outdoor units, especially the components on the roof, are important in order to recognise and rectify blockages or loose parts. This prevents the air flow from being obstructed.
- Check remote control problems: Replace dead batteries or insert fresh batteries into the remote control to ensure that you can control the air conditioning correctly.
Manufacturer's recommendations for troubleshooting
Air conditioning manufacturers have specific instructions and tips to help you troubleshoot:
- Truma Aventa Comfort: Make sure that the target temperature is well below room temperature. A red LED signals a problem; if an error occurs, perform a reset. Clean the appliance's air filters regularly. A brief power failure or the use of the reset button can help with error messages.
- Dometic FreshJet: Activate cooling mode and set the temperature correctly. Check the power supply, especially the RCD switch and fuses. Clean the air filters and louvres thoroughly. Error codes such as "E1" indicate a communication fault, while "E2" indicates a problem with the temperature sensor - refer to the manual in each case and follow the recommended procedure. A power failure and subsequent restart of the device can often resolve problems.
- Telair Silent 8400H: Use the remote control to activate "Cold" mode and check the batteries. Ensure that the power supply is uninterrupted. Errors are not indicated by codes, but by a functional breakdown; the "Troubleshooting" chapter in the manual offers detailed solution steps. Clean the air filters regularly according to the instructions.
When is professional help necessary?
If there is no cooling after these steps, there may be a technical problem, e.g. B. Loss of refrigerant or defective sensor or compressor. In this case, you should contact your Bürstner dealer or a specialist company. You can find service partners via the Bürstner dealer search.
⚠️ Safety instructions
Only carry out electrical work when the power supply is switched off. Use suitable protective measures when testing electrical components.
💡 Our tip
Regular maintenance can prevent many problems. A visual inspection of the external components and cleaning of the air filters will significantly improve the efficiency of your air conditioning system.
