Midea Precision AC Technical Manual MCAC-PDSM-2013-01

Symptom

Probable reason

Check items or handling methods

Air suction and

exhausting pressure

have no difference

after operation.

Reverse the compressor or inner air

mixed up.

When the compressor was reversed, change

any two L wires. Inner air mixed up, change

the compressor, Check the leakage and

maintain, and add refrigerant, change the

drier-filter.

Symptom

Probable reason

Check items or handling methods

High air exhausting

temperature

Refrigerant leakage.

Check whether the leakage and maintain, and

add refrigerant.

Symptom

Probable reason

Check items or handling methods

High air exhausting

pressure

Condenser has been blocked.

Clean the condenser.

Condenser fan cannot run.

1, Check the wiring was correct or not.

2, Check whether it has 3~10V DC between

wire 22 and wire 05. If has, the outdoor

inverter is error. And if no, check the indoor

unit controller.

Too much refrigerant adding amount.

Fasten the connection.

Symptom

Probable reason

Check items or handling methods

Low air

suction

pressure or

return liquid.

Lack of refrigerant in system.

Check the leakage and maintain, add

refrigerant.

Air filter too dirty

Change the air filter.

Drier-filter is blocked.

Change the drier-filter.

Non-correct overheat adjustment

Strictly accord to the adjustment steps to

adjust the thermal expansion valve.

Expansion valve error.

1, Check the temperature sensor and the

balance pipe whether have leakage.

2, Check the expansion valve whether has

serious frosting.

Condensed pressure too low

Check the fan operates normally or not.

Belt creep

Check the belt and adjust it.

Symptom

Probable reason

Check items or handling methods

Large

compressor

noise.

Return liquid.

Refers to Low air suction pressure or return

liquid.

Lubricating oil lost and cause bearing

damaged.

Add the lubricating oil.

Compressor or pipe line is loose.

Fasten the connection.



Common faults and handling methods of outdoor fan system

Both error and alarm are the abnormal working states of inverter. But there are different. Inverter
will self-check during operation. If there is error, the inverter will display error code, and cut off
