Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
Operational Fault | No operating voltage or blown appliance/vehicle fuse. | Check the battery voltage (12 V / 24 V) and charge if necessary; check all electrical plug connections; check and replace appliance or vehicle fuses if necessary. | DIY Safe |
Operational Fault | The temperature set on the control unit is lower than the ambient temperature. | Increase the target room temperature setting on the control unit. | DIY Safe |
Operational Fault | Window above the chimney is open (window switch activated). | Close the window. | DIY Safe |
Operational Fault | Low voltage (undervoltage) or high voltage (overvoltage) range. | Charge the battery or check the battery voltage and power sources (e.g., charger). | DIY Safe |
Operational Fault | Gas bottle or quick-acting valve in the gas supply line is closed, or combustion air intake/exhaust gas outlet is blocked. | Check the gas supply and open valves; remove the chimney cap and check for dirt (slush, ice, leaves, etc.). | DIY Safe |
Operational Fault | Hot air outlets blocked, circulating air intake blocked, or gas pressure regulator frozen. | Check individual outlet openings; clear blockages in the circulating air intake; use the regulator heater (EisEx). | DIY Safe |
Operational Fault | No operating voltage or device/vehicle fuse is defective. | Check 12 V / 24 V battery voltage and charge if necessary; check all electrical plug connections and fuses. | DIY Safe |
Operational Fault | The temperature setting on the control panel is lower than the room temperature. | Select a higher room temperature at the control panel. | DIY Safe |
Operational Fault | Window above the cowl is open (triggered via window switch). | Close the window. | DIY Safe |
Operational Fault | Undervoltage range (12V: 10.9V - 10.5V) or overvoltage range (12V: 15.8V - 16.4V). | Charge battery or check battery voltage and voltage sources such as the charger. | DIY Safe |
Operational Fault | Gas cylinder or quick-acting valve closed, or combustion air intake/exhaust outlet sealed. | Check gas supply and open valves; remove cowl cover and inspect openings for contamination. | DIY Safe |
Operational Fault | Warm air outlets blocked, circulated air intake blocked, or gas pressure regulation system iced up. | Inspect individual outlet openings, remove blockage from circulated air intake, or use regulator heater (EisEx). | DIY Safe |
