Daewoo C1

Q: What does error code C1 mean on a Daewoo appliance?

Daewoo error code C1 indicates: Compressor Fault or Continuous Operation.

Q: What is the root cause of Daewoo error code C1?

The primary root cause for Daewoo code C1 is: The compressor has been running for an abnormally long period. This could be due to a refrigerant leak, a sealed system restriction, or a faulty compressor..

Q: How do I fix or resolve Daewoo error code C1?

To resolve error code C1: This error typically requires a certified technician to diagnose and repair the sealed refrigeration system.

Q: Is it safe to clear Daewoo error code C1 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Daewoo code C1 persists, the physical component causing The compressor has been running for an abnormally long period. This could be due to a refrigerant leak, a sealed system restriction, or a faulty compressor. must be inspected or replaced.

Q: How do I test electrical resistance for Daewoo code C1 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test Compressor Motor Windings (Run/Start) & Defrost Heater across Across 3 compressor pins (Common, Run, Start): R(C-S) + R(C-R) = R(S-R). Winding to earth: >20MΩ (OL).. Expected nominal reading is 15Ω–25Ω (Run C-R), 20Ω–35Ω (Start C-S), 200Ω–400Ω (Defrost Heater). PTC Relay: 10Ω–30Ω at 25°C.. Tolerance: ±10%. Any low insulation resistance to casing (<2MΩ) trips the breaker. Defrost bimetal reads <0.5Ω when sub-zero..

Q: What safety protocol must be followed before servicing Daewoo code C1?

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.

1. Pre-Intervention Electrical Safety Protocols

!Refrigeration Safety Protocol: Disconnect mains power before unclipping compressor terminal covers.
!Flammable Refrigerant Warning: R600a (isobutane) is flammable. Never puncture cooling tubes or use open flame.
!High Surface Temperature: Compressor shell can exceed 80°C during normal operation. Allow to cool before inspection.

3. Preliminary Mechanical & Visual Checks

Listen for compressor startup attempts: repetitive clicking every 60 seconds indicates locked rotor or failed PTC relay.
Inspect evaporator coil for thick solid frost buildup, signaling defrost heater, sensor, or timer failure.
Clean condenser coils and check cooling fan motor for free rotation and dust accumulation.
