Quick answer
EC on a Singer AC means the system has detected low refrigerant — the unit is likely leaking gas. The compressor stops to prevent damage from running with insufficient charge.
What EC means
EC is a refrigerant-shortage protection code. The control board monitors suction pressure and temperature patterns to detect when the gas charge has dropped below safe levels. Running a compressor with low refrigerant causes overheating and eventual failure — EC prevents this.
Do not keep restarting. Each restart with low gas stresses the compressor. Call a technician.
What to do
- Turn the AC off and do not restart.
- Check the outdoor pipes. Frost on the large (suction) pipe is a strong indicator of low gas.
- Call a licensed technician or Singer service (09678-300300). They will leak test, repair, vacuum, and recharge.
- Common leak points: Indoor and outdoor flare connections, service valve caps, evaporator U-bends.
Bangladesh tip: Poor installation (loose flare nuts) is the leading cause of gas leaks. If EC appears within the first few months, contact the installer — it should be covered under installation warranty. Gas recharge typically costs 2000-5000 BDT depending on tonnage and refrigerant type.
What does the EC code mean?
EC indicates low refrigerant charge detected. The system has lost gas from a leak and the compressor is stopped.
Common causes
- Refrigerant leak at flare connections (most common)
- Leaking service valve
- Evaporator or condenser coil corrosion
- Pipe damage during installation
- Insufficient initial charge

How to fix the EC error
Stop the AC
Do not restart.
Check outdoor pipes
Frost on suction pipe = low gas.
Call Singer service
09678-300300.
Technician will
Leak test, repair, vacuum, recharge.
Check installation warranty
If EC appears early, installer should fix for free.
Safety first: Refrigerant (R32/R410A) is a high-pressure gas. Only licensed technicians should handle leak repair and recharging.
Part you may need: Refrigerant leak repair and recharge
Singer uses R32 in most newer models. Recharge cost: approximately 2000-5000 BDT in Bangladesh.
Frequently asked questions
Can I just top up the gas?
No — without fixing the leak, gas will escape again.
How much does recharge cost?
2000-5000 BDT in Bangladesh depending on tonnage.
Does Singer warranty cover gas leaks?
Manufacturing defects yes. Installation errors — contact the installer.
