Dometic 10-Series

Possible Cause: The fuse in the AC power supply is defective or the vehicle is not connected to the AC power supply, or the AC heating element is defective.

Possible Cause: The fuse in the DC supply is defective, vehicle fuse has blown, vehicle battery is discharged, ignition not turned on, or DC heating element is defective.

Possible Cause: The gas cylinder is empty, the gas valve is closed, or air is in the supply line.

Possible Cause: Sensor failure.

Possible Cause: Low mains voltage or disconnected.

Possible Cause: Disconnected DC supply.

Possible Cause: Supply voltage is too high.

Possible Cause: Door left open.

Possible Cause: Communication failure.

Possible Cause: Device is at an angle or unit failure.

Possible Cause: Valve or module communication failure.

Possible Cause: Depleted batteries in standalone packs.

Possible Cause: Ignition not possible, gas cylinder empty.

Possible Cause: Refrigerator installed to the side of air inlet and outlet vents or clearance behind refrigerator exceeds 25 mm without an air guide.

Possible Cause: Inadequate heat dissipation from the condenser or lack of proper baffling.

Possible Cause: Air inlet vent located too high, preventing complete evacuation of unburned gas.

Possible Cause: External ventilation grilles left fully open when replacing an absorption unit with a compressor unit.

Possible Cause: Blown fuse in DC power supply, blown vehicle fuse, flat vehicle battery, ignition not turned on, or low input voltage triggering safety shut-off (<10.4 V)

Possible Cause: External ambient temperature too cold causing compressor compartment issues

Possible Cause: Inadequate ventilation around the cooling unit, evaporator iced up, temperature set too high, high ambient temperature, or too many warm/fresh food items loaded at once

Possible Cause: Faulty or disconnected internal temperature sensor

Possible Cause: Bus or display communication failure

Possible Cause: Refrigerator door left open

Possible Cause: Electrical overcurrent, mechanical lock, or overheating of compressor control unit

Possible Cause: Refrigerant circuit compromised

Possible Cause: DC heating element (12V) connected directly to battery without ignition relay

Possible Cause: External ventilation grilles are not fully closed

Possible Cause: Blown DC power supply fuse, vehicle fuse blown, discharged vehicle battery, ignition not switched on, compressor temperature too low (<0 °C), or supply voltage dropped below cut-off threshold.

Possible Cause: Inadequate ventilation around cooling unit, evaporator iced up, temperature set too high, ambient temperature too high, or too many warm/fresh food items placed inside simultaneously.

Possible Cause: Defective temperature sensor

Possible Cause: Internal communication failure between display and control units

Possible Cause: Cooling fan drawing excessive current or jammed

Possible Cause: Compressor unit locked or electrical drive failure

Possible Cause: System blockage or excessive operating load

Possible Cause: Overheating of the compressor electronics due to poor ventilation

Possible Cause: Battery management system shut down device to protect vehicle battery

Possible Cause: Inadequate heat dissipation or blocked ventilation openings

Possible Cause: Clearance between refrigerator and rear wall exceeds 25 mm without an air guide

Possible Cause: Fuse in the direct current power supply is defective or vehicle fuse is blown

Possible Cause: Input voltage is insufficient (drops below 10.4 V)

Possible Cause: Sensor failure or disconnection

Possible Cause: Compressor or fan electrical overload/fault

Possible Cause: Vehicle battery management system shutting down device to protect battery

Possible Cause: The fuse in the AC power supply is defective, the vehicle is not connected to AC mains, or the AC heating element is defective.

Possible Cause: Defective fuse in DC supply/relay, blown vehicle fuse, discharged vehicle battery, ignition not turned on, or defective DC heating element.

Possible Cause: Gas cylinder empty, gas valve closed, air in the supply line, or gas lock after ignition failures.

Possible Cause: Faulty sensor hardware or wiring.

Possible Cause: Missing 12V supply connection.

Possible Cause: Supply voltage exceeds safe operational thresholds.

Possible Cause: Communication cable failure or module fault.

Possible Cause: Unit is operating at an unlevel angle or cooling unit failure.

Possible Cause: Empty gas cylinder or ignition failure.

Possible Cause: Air intake and exhaust vents covered or blocked by vehicle parts, bicycle racks, or improper clearances (gap to rear wall > 25 mm without guide).

Possible Cause: Inadequate sealing between the rear of the refrigerator and the vehicle interior, or missing gas floor drain when bottom vent is misaligned.

Possible Cause: DC heating element (12V) connected directly to the battery without an ignition-controlled relay.

Possible Cause: Cooling circuit damaged or ruptured

Possible Cause: Refrigerator tilt exceeds 3° angle, blocked ventilation grills, incorrect gap behind the refrigerator (>25 mm), or exposure to excessive heat

Possible Cause: Frequent door opening, storing warm food, or clogged/improperly routed condensation drain

Possible Cause: Damaged cooling circuit or absorption aggregate

Possible Cause: Back wall distance greater than 25 mm or blocked ventilation

Possible Cause: DC heating element power supply connected without ignition-controlled relay

Possible Cause: Air intake or exhaust vents blocked, gap between refrigerator and rear wall exceeds 25 mm without an air guide, or unit is installed improperly next to air intake/exhaust.

Possible Cause: Inadequate sealing between the rear of the refrigerator and the vehicle interior, or lack of proper draught protection.

Possible Cause: DC heating cartridge connected to constant 12V supply instead of an ignition-controlled relay.

Possible Cause: Cooling unit circuit damaged / ruptured

Possible Cause: Excessive gap (>25 mm) between the refrigerator and the rear wall, or blocked airflow

Possible Cause: 12V DC heating element (supply line C) not wired through an ignition-controlled relay

Possible Cause: Refrigerator distance to the rear wall is greater than 25 mm or unit installed beside air vents / excessive heat.

Possible Cause: Inadequate airtight sealing between the back panel of the combination and the vehicle interior.

Possible Cause: Heating element DC supply line connected directly to battery without an ignition-controlled relay.

Possible Cause: Damaged cooling unit circuit

Possible Cause: DC heating element (C line) running without an ignition-controlled relay

Possible Cause: Distance between refrigerator and rear wall exceeds 25 mm, or inadequate ventilation
