The short answer
Before anything else, work out which kind of cooler you own, because these names cover two quite different machines: a compressor unit that cools like a refrigerator, and a thermoelectric unit that can only pull a fixed amount below the room temperature. A thermoelectric unit usually has no display and no codes at all, so a code means you have a compressor unit. A refrigerator holds food safely at 40 °F (4 °C) or below.
What you are seeing
- You are not certain whether the unit is a compressor or a thermoelectric cooler
- 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
- A near-miss symptom: a display that dims to save power, which is normal on many models
- Body: The code and what accompanies it are the diagnosis: You are not certain whether the unit is a compressor or a thermoelectric cooler. 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. A near-miss symptom: a display that dims to save power, which is normal on many models.
Causes, most likely first
- A unit with no display being expected to show a code — Why: many thermoelectric coolers have only a switch, so an owner looking for an error code on one is looking for something that does not exist.
- A compressor unit reporting a supply or ambient condition — Why: if there is a code, the unit is a compressor model and the code almost certainly reports the supply or the environment rather than a component.
- 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.
- A poor connection resetting the unit — Why: a plug that has worked loose interrupts the supply briefly, which is why the unit forgets its setting rather than showing an error.
- A failed control board — Why: the diagnosis of last resort, and it is reached only after the supply, the ambient and the vents have all been eliminated.
- Body: Ranked by what these codes actually report: First, A unit with no display being expected to show a code: many thermoelectric coolers have only a switch, so an owner looking for an error code on one is looking for something that does not exist. Second, A compressor unit reporting a supply or ambient condition: if there is a code, the unit is a compressor model and the code almost certainly reports the supply or the environment rather than a component. Third, 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. Fourth, 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. Fifth, A poor connection resetting the unit: a plug that has worked loose interrupts the supply briefly, which is why the unit forgets its setting rather than showing an error. Sixth, A failed control board: the diagnosis of last resort, and it is reached only after the supply, the ambient and the vents have all been eliminated.
What to check, in order
- check whether the unit has a display at all, because that answers which machine you have in a single step.
- 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.
- clear the vents and move the unit out of the sun, then see whether the code returns in cooler conditions.
- Body: Follow the code to the supply and the environment first: First, check whether the unit has a display at all, because that answers which machine you have in a single step. Second, 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. Third, try the unit on mains power: a code that disappears on mains is a low-voltage supply code. Fourth, clear the vents and move the unit out of the sun, then see whether the code returns in cooler conditions.
Checks you can do yourself
- Look for a display and controls beyond a simple on-off switch — Tools: none — 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
- Clear a hand’s width around every vent, move the unit out of the sun and watch whether the code returns — Tools: none — Time estimate: overnight
- Body: Owner checks stop at the supply and the vents: Look for a display and controls beyond a simple on-off switch (none; 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). Clear a hand’s width around every vent, move the unit out of the sun and watch whether the code returns (none; overnight).
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 unit is a compressor model and the fault persists with the supply proven and the vents clear. The display works and the compressor never runs on any supply. The code names a sensor or a component rather than a supply condition. The display has dead segments or unresponsive buttons.

What this page does not cover
This page is generalized across every cooler sold under the BODEGA name: it separates neither the compressor units from the thermoelectric ones and the portable boxes from the indoor cabinets, 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. The BODEGA name appears on both compressor and thermoelectric coolers, and the two machines fail in completely different ways. The companion pages cover the portable compressor form, the indoor beverage-cooler form, the dual-zone models and the deeper diagnostic tier. For the other faults that turn up on this machine, start from BODEGA Refrigerator: Controls, Display or Error Code.
