What it means

This code appears on Samsung inverter split wall units such as WindFree and Digital Inverter. It means the total current the outdoor unit draws from the supply went above its limit, so the outdoor board stopped the compressor for protection. The cause is usually overload or low supply voltage. The wording varies slightly between outdoor units, and the same code can mean something else on other brands.

Models covered: Samsung inverter split air conditioners (e.g. WindFree and Digital Inverter wall units) that show three-digit E codes on the display.

Symptoms4

E462 shows at hot peak hours and cooling stops.
The unit runs, stops and restarts repeatedly.
Cooling is weak before the code appears.
The breaker may trip at times.

Possible causes6

Dirty condenser or poor ventilation around the outdoor unit, raising pressure and current.
Low or unstable supply voltage, or loose connections.
Refrigerant overcharge or air in the system.
Weak outdoor fan.
Fault in the current sensing or power factor correction circuit on the outdoor PCB.
A worn compressor drawing more current than normal.

How to diagnose5

Switch off the breaker for several minutes and make sure the outdoor unit is clean and well ventilated.
Note whether the code matches times of weak supply or extreme heat.
A technician measures voltage and current with the compressor running and compares them with the nameplate.
Wash the condenser, measure pressures against Samsung specification and check the outdoor fan.
If actual current is normal, check the current sensing circuit on the outdoor board.

How to fix6

Wash the condenser and give the outdoor unit ventilation and shade.
Fix connections and fit a voltage protector if the supply is weak or unstable.
Correct the refrigerant charge by evacuating and weighing in (licensed technician).
Repair the outdoor fan.
Replace the outdoor PCB if sensing is faulty, or the compressor if it is proven to draw excess current.
Run the unit at peak time and confirm the code does not return.

In Saudi riyals; the highlighted part is the expected range for this fault.

A wash and voltage correction solve many cases at moderate cost; the outdoor PCB costs more, and a compressor is the top of the range.

Prices are rough estimates including the part and the technician’s fee, and vary with brand, model and part source.

Frequently asked questions

Is E462 linked to the home power supply?

Often yes. Low voltage at peak times raises the current the unit draws, pushing it past the limit. Measuring voltage while running is the first step.

What is the difference between E462 and E464?

E462 concerns the total current drawn from the supply. E464 concerns the current in the IPM that drives the compressor directly.
