Elinge refrigeration unit error codes
The codes follow the Elinge passport and operating manual. The same code means different things on different control blocks, so the tables are split: first identify the block, then read the code.
The reason for splitting: Pr2 on the Л-01 and Л-02 block is a blown power fuse, while on the EVK-213 block it is an evaporator temperature sensor alarm. The component to check differs.
Control block Л-01 / Л-02
| Code | Meaning |
|---|---|
| ALB | no link between the power block and the display: the harness is broken or the control board on the condenser has failed |
| OBC | open circuit in the condenser fan |
| ErC | short circuit in the condenser fan |
| OBI | open circuit in the evaporator fan |
| ErI | short circuit in the evaporator fan |
| CPE | short circuit in the compressor circuit; also appears when the on-board voltage is low |
| CPO | open circuit in the compressor |
| ECL / OCL | short or open circuit in the defrost valve |
| ECC / OCC | short or open circuit in the shut-off valve |
| DtE | open or short circuit in the body or evaporator temperature sensor |
| tIE / tIO | short or open circuit in the evaporator temperature sensor |
| AdE | refrigerant pressure alarm on the first sensor, high-pressure side |
| Ad2 | refrigerant pressure alarm on the second sensor, low-pressure side; normal range 1–29 bar |
| Pr1 | power fuse 1 has blown |
| Pr2 | power fuse 2 has blown |
| BLC | the condenser fan is jammed by a foreign object |
| BLI | the evaporator fan is jammed by a foreign object |
Control block EVK-213
| Code | Meaning |
|---|---|
| Pr1 | body temperature sensor alarm: open, short, or the wrong probe type is set |
| Pr2 | evaporator temperature sensor alarm: open, short, or the wrong probe type |
| Ld | refrigerant pressure is critically low or high; the signal repeats every four seconds |
| LOC | the keypad lock is on; hold SET for three seconds to release |
Besides the codes, the block sounds an alarm when the body temperature leaves the −55…+99 °C range.
What can be checked on the spot
A compressor error below −20 °C: the manufacturer prescribes warming the vehicle in a heated bay and leaving the unit running after departure. On a 12 V system the voltage is checked — it must stay above 11 V, as a voltage drop triggers a compressor circuit error. If the code persists after warming and a voltage check, diagnostics are needed.
Codes А01, А04, А22 and Carrier units
Designations such as А01, А04 and А22 do not belong to Elinge: the factory documentation uses letter codes. They come from units of another make, and decoding them from a third-party table would be wrong. Quoting the code from the display is enough when you call.
The passport, operating manual and wiring diagrams of Elinge units are on the manufacturer’s site: Elinge technical documentation.
FAQ
Why is one code decoded in two ways?
Because the control blocks differ. On Л-01 and Л-02 Pr2 is a blown power fuse; on EVK-213 it is an evaporator sensor alarm.
Can the error be cleared without a service?
Some causes can: warming the vehicle in frost, checking that the on-board voltage stays above 11 V, removing a foreign object from a fan. The rest needs diagnostics.
Are Carrier codes listed?
Not yet: Carrier manuals are not published openly, and decoding codes from third-party tables is not acceptable. The section will appear once there is an official source.
