Atosa Prep Table Error Code CA: Serious External Alarm
CA on an Atosa prep table with the digital controller is a serious external alarm, and all outputs are off, so the compressor and fans stop and the table warms. Check food temperature, move perishables to another cooler, check the plug is seated, and keep the lid and doors closed until we arrive.
High: all outputs are off, so the table is warming and food is at risk.

What does Atosa error code CA mean?
The digital controller has an input for a device wired to it, such as an outside alarm or switch. CA is the serious version of that alarm. When the device tells the control to shut down, or when a wire at the input comes loose or shorts, the control switches every output off. That means the compressor and the fans stop and the pan area begins to warm. This is the key difference from EA, where the same kind of alarm leaves the table running. Because CA stops the cooling, food in the pans is at risk quickly, and the first job is protecting the food rather than finding the cause. The manual's list covers the device wired to the serious alarm input, a loose or shorted wire at the input, settings that define the input, and the control input itself. On a prep table that input is rarely used for anything, so a loose wire or a changed setting is a realistic reading.
Affected models and control systems
This applies to Atosa MSF and MPF refrigerated prep tables with the digital controller, such as the MSF8302GR, MSF8307GR and MPF8202GR. Other controller generations use different codes.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- CA shows and the compressor and fans are off
- The pans and well warm up with the lid shut
- The table is silent when it should be cycling
- The message appears with no obvious cause
Possible causes
Listed in Atosa's documentation
- A device wired to the serious alarm input has signalled shutdown
- A loose or shorted wire at the input
- Settings define the input as active
- The control input has failed
Other likely causes — what usually sits behind error code CA on this control. A technician confirms which one it is before any part is replaced.
- An input wire that has been shaken loose or shorted while the table was moved for cleaning
- A setting changed at the keypad that turned an unused input into an active serious alarm
- A power connection to the control that made contact and cut out
Safe checks before calling for service
- Check food temperature in the pans with a thermometer.
- Move perishable food to another cooler.
- Check that the plug is fully seated and firm.
- Keep the lid and doors closed until we arrive.
- Write down the time CA first appeared.
How a technician diagnoses error code CA
- Read the code and check whether all outputs are off.
- Identify what, if anything, is wired to the alarm input.
- Check the input wiring for a loose or shorted conductor.
- Review the settings that define the input.
- Test the control input with the wire isolated.
- Replace the control only after the wiring and settings are cleared.
- Food is warming while the table is off, so the cause has to be found quickly.
- The input wiring is inside the control area and needs a meter and the manual's parameters.
- A wrong setting can bring the alarm back or hide a real one.
How error code CA differs from similar codes
EA is the milder alarm on the same input, where outputs are unchanged and the table keeps cooling.

We use the maker's document to read the code and do not reproduce it. Always confirm the complete model and control before applying these steps.
Related Atosa prep table error codes
Is the table still cooling when CA shows?
No. All outputs are off, so it warms.
Is CA the same as EA?
No. EA leaves the outputs running, while CA turns them off.
How long can food stay in?
Measure it. Move perishables once the pans leave a safe range.
