The short answer
This page covers the portable compressor cool box — the form these units take when they run from a vehicle or a leisure battery. Used that way, nearly every code it shows is about the battery it is connected to rather than about the box itself. A refrigerator holds food safely at 40 °F (4 °C) or below.
What you are seeing
- The problem appears in the vehicle and not when the box is run indoors
- A code on the display with the compressor stopped
- A code that appears only when the engine is off
- A code that appears on hot days and clears in the evening
- The display working while the compressor never runs
- The unit forgetting its setting each time it is reconnected
- Body: The code and what accompanies it are the diagnosis: The problem appears in the vehicle and not when the box is run indoors. A code on the display with the compressor stopped. A code that appears only when the engine is off. A code that appears on hot days and clears in the evening. The display working while the compressor never runs. The unit forgetting its setting each time it is reconnected.
Causes, most likely first
- A code raised the moment the engine stops — Why: many vehicles switch or unload their accessory sockets with the ignition, and the resulting voltage drop raises a protection code within moments.
- A code raised only after several hours — Why: this is the battery discharging normally, and the protection is doing exactly what it exists for rather than reporting a fault.
- Supply voltage below the protection threshold — Why: the most common code on this class of appliance exists to protect a vehicle battery, and it appears whenever the supply sags under compressor load.
- A high-ambient or overheat condition — Why: the unit stops the compressor when it cannot reject heat, so a code that appears on hot afternoons and clears in the evening is reporting the environment rather than a fault.
- A blocked vent or fan raising the same condition — Why: the same protection triggers when the vents are packed against luggage, and clearing them clears the code.
- A sensor the unit cannot read — Why: this gives a code with the fan and display working normally, and it is the first cause in the list that is genuinely internal.
- Body: Ranked by what these codes actually report: First, A code raised the moment the engine stops: many vehicles switch or unload their accessory sockets with the ignition, and the resulting voltage drop raises a protection code within moments. Second, A code raised only after several hours: this is the battery discharging normally, and the protection is doing exactly what it exists for rather than reporting a fault. Third, Supply voltage below the protection threshold: the most common code on this class of appliance exists to protect a vehicle battery, and it appears whenever the supply sags under compressor load. Fourth, A high-ambient or overheat condition: the unit stops the compressor when it cannot reject heat, so a code that appears on hot afternoons and clears in the evening is reporting the environment rather than a fault. Fifth, A blocked vent or fan raising the same condition: the same protection triggers when the vents are packed against luggage, and clearing them clears the code. Sixth, A sensor the unit cannot read: this gives a code with the fan and display working normally, and it is the first cause in the list that is genuinely internal.
What to check, in order
- note whether the code appears at the moment the engine stops or hours later, because those are two different situations with the same code.
- note the exact code and what the unit was connected to when it appeared, because supply codes and ambient codes look identical without that context.
- look it up in the manual for your model rather than for the brand, since these units are sold under several names with different tables.
- try the unit on mains power: a code that disappears on mains is a low-voltage supply code.
- Body: Follow the code to the supply and the environment first: First, note whether the code appears at the moment the engine stops or hours later, because those are two different situations with the same code. Second, note the exact code and what the unit was connected to when it appeared, because supply codes and ambient codes look identical without that context. Third, look it up in the manual for your model rather than for the brand, since these units are sold under several names with different tables. Fourth, try the unit on mains power: a code that disappears on mains is a low-voltage supply code.
Checks you can do yourself
- Record the time between the engine stopping and the code appearing — Tools: a clock — Time estimate: a few minutes
- Photograph the code and note what the unit was connected to and how hot it was — Tools: phone — Time estimate: a few minutes
- Find the code in the manual for your model and read what condition it reports — Tools: the model manual — Time estimate: a few minutes
- Connect the unit to mains power and see whether the code clears and the compressor runs — Tools: the mains adapter — Time estimate: a few minutes
- Set the battery-protection mode to its lowest setting and retry on the low-voltage supply — Tools: the model manual — Time estimate: a few minutes
- Body: Owner checks stop at the supply and the vents: Record the time between the engine stopping and the code appearing (a clock; a few minutes). Photograph the code and note what the unit was connected to and how hot it was (phone; a few minutes). Find the code in the manual for your model and read what condition it reports (the model manual; a few minutes). Connect the unit to mains power and see whether the code clears and the compressor runs (the mains adapter; a few minutes). Set the battery-protection mode to its lowest setting and retry on the low-voltage supply (the model manual; a few minutes).
Safety first
Safety
A refrigerator holds food safely at 40 °F (4 °C) or below. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Do not defeat a protection setting to keep the compressor running from a vehicle battery: that protection exists so the vehicle will still start. Stop using any lead or socket that becomes warm. unplug-before-service fridge-40f
When to stop and call a technician
These need a technician: The box fails on mains power indoors as well as on the low-voltage supply. The code persists on mains power with clear vents and a normal ambient. The display works and the compressor never runs on any supply. The code names a sensor or a component rather than a supply condition.

What this page does not cover
This page is generalized across every cooler sold under the BODEGA name: it separates neither the portable low-voltage boxes from the mains-only cabinets and the single-zone units from the dual-zone ones, and it names no individual model. Where a family- or model-specific page exists it is linked here and it outranks this one for that machine; at present no page beneath this one narrows to a single family, so treat the ranking above as the brand-level pattern rather than a reading of your serial plate. These names — BODEGA, BODEGACOOLER, AOBOSI and AAOBOSI — appear on the same family of compact compressor coolers. The companion pages cover the indoor beverage-cooler form, the dual-zone models, the deeper diagnostic tier, and how to tell a compressor unit from a thermoelectric one. For the other faults that turn up on this machine, start from Common BODEGA?BODEGACOOLER?AOBOSI, AAOBOSI Refrigerator Problems.
