Troubleshooting

Symptoms: Unit does not start

Possible Causes: MCB has tripped

Suggested Remedy: Reset MCB

Symptoms: Fuse has burnt

Possible Causes:

Input voltage to the stabiliser is below acceptable range
Replace fuse wire

Suggested Remedy:

If the input voltage to the stabiliser is below the acceptable range, the airconditioner will not turn on

Symptoms: Unit does not cool even after the normal time delay of approx. 2 minutes

Possible Causes:

Compressor is off (not in Auto or Cool Mode)
The airflow paths of either or both the indoor & outdoor units are not free
The air-filter is not clean

Suggested Remedy:

Use the remote to turn the compressor on
Remove all obstructions to make the airflow paths free
Clean the air-filter

NOTE: If the unit still does not work, or if any other types of symptoms are encountered, shut off the mains (switch fuse unit) and call the service engineer/technician.

Midea VRF Error Codes

R410A All DC Inverter V4 Plus R Series 50/60Hz Error Codes: V4 VRF: Advanced 3-pipe technology enables heat recovery between indoor units for unprecedented economy and performance. It can simultaneously operate in cooling and heating mode when it is necessary to provide more freedom for operation. It compensates and adjusts when there are hot and cold rooms in the same building, depending on the direction of sunshine. As a result, it reduces annual power consumption. Midea VRF Error Codes Error Codes Problem E0 Communication error between outdoor units. Only display on the faulty slave unit, all the ODUs are in standby. E1 Phase sequence error. Display on the faulty unit, all the ODUs are in standby. E2 Communication error between indoors and the master unit. Only display on the master unit, all the ODUs are in standby. E4 Outdoor ambient temperature sensor (T4) and condenser pipe temperature sensor (T3/T5) error. Display on the faulty unit, all the ODUs are in ...

LG VRF Error Codes – Multi V

Error Codes; Indicate different types of unit failures, assist in self-diagnosis and to track the frequency of occurrence. Error codes are shown on the LED of indoor units, wired remote controller, the outdoor unit control board, and on the main screen of the LG Monitoring View (LGMV) Diagnostic Software. If two or more errors occur simultaneously, the lower error code number is displayed first. After error is resolved, the error code does not display. Error Display; The first, second, and third number on the LED indicates error number; the fourth number on LED indicates outdoor unit number. Examples: 211 = Error No. 21 on master unit, 213 = Error No. 21 on slave2 unit, Error No. 105 on master unit on compressor 1. Error Code Nomenclature Definitions; MICOM: Non-volatile memory chip where unit setup information is stored. EPROM: Non-volatile memory chip where device identification, size, and factory defined default component operating parameters are stored. LG Multi V Erro...
