How to Remove E1 Error in Giatsu Air Conditioner?
- Error: E1
- Description: Communication error between the indoor and outdoor units.
- Cause: Various, read below.
- Solution: Often, this error can be resolved by resetting the device. If not, refer to the step-by-step guide to fix it.
Error Code E1 is a clear indicator of a communication failure between the indoor and outdoor units of a system. This issue can arise for various reasons, but with proper diagnostic and solution procedures, it can be effectively resolved.
Error Description and Causes:
- Error Description: Positive fluctuation in Vs measurement.
- Cause: This fluctuation in the Vs measurement, representing the voltage between the red wire (S) and the black wire (N), indicates a possible issue in the wiring of the outdoor unit.
- Error Description: Faulty reactor.
- Cause: If the wiring of the outdoor unit is in good condition and the positive fluctuation in Vs measurement persists, the likely cause is a faulty reactor. In this case, replacing the reactor is required.
- Error Description: Damaged exterior PCB.
- Cause: If, after replacing the reactor, the error persists, the next area to consider is the exterior Printed Circuit Board (PCB). A damaged PCB can interfere with the communication between the indoor and outdoor units.
- Error Description: Persistent problem after replacing the exterior PCB.
- Cause: In the event that error code E1 continues after replacing the exterior PCB, the next option is the interior PCB. This board may be the underlying cause of the communication failure between the units.
- Error Description: Vs measurement shows no positive fluctuation.
- Cause: If the Vs measurement doesn’t show the expected positive fluctuation, it’s necessary to check the wiring of the indoor unit. There may be a problem in this part of the system.
- Error Description: Faulty interior PCB.
- Cause: If the wiring of the indoor unit is in good condition but the error persists, the likely cause is a faulty interior PCB. In this case, replacing the interior PCB is recommended.
- Error Description: Persistent problem after replacing the interior PCB.
- Cause: If error code E1 continues to appear even after replacing the interior PCB, the last option to consider is the exterior unit’s PCB. A damaged PCB at this point can be the root of the communication problem.
Step-by-Step Guide to Resolve E1 Error for Giatsu Air Conditioner:
Step 1: Verify Vs Measurement (Voltage)
- Locate the red (S) and black (N) wires connecting the indoor and outdoor units.
- Measure the voltage between these wires using a multimeter. This measurement is known as “Vs.”
Step 2: Identify a Positive Fluctuation in Vs Measurement
- If the Vs measurement shows a positive fluctuation, proceed to Step 3.
- If the Vs measurement does not show a positive fluctuation, skip to Step 5.
Step 3: Verify Outdoor Unit Wiring
- Carefully examine the wiring connecting the outdoor unit. Ensure there are no short circuits, loose connections, or visible damage.
- If the wiring appears to be in good condition, move to Step 4.
Step 4: Replace the Reactor (If Necessary)
- If the wiring is in good condition but the positive fluctuation persists, the reactor may be faulty.
- Disconnect the unit from the power source and proceed to replace the reactor following the manufacturer’s instructions.
Step 5: Verify Indoor Unit Wiring
- Examine the wiring connecting the indoor unit. Ensure there are no short circuits, loose connections, or visible damage.
- If the wiring appears to be in good condition, move to Step 6.
Step 6: Replace the Interior PCB (If Necessary)
- If the wiring is in good condition but the positive fluctuation persists, the interior PCB may be faulty.
- Disconnect the unit from the power source and proceed to replace the interior PCB following the manufacturer’s instructions.
Step 7: Replace the Exterior PCB (If Necessary)
- If, after replacing the interior PCB, the problem persists, the exterior PCB may be faulty.
- Disconnect the unit from the power source and proceed to replace the exterior PCB following the manufacturer’s instructions.
Step 8: Verify if the Problem is Resolved
With all components replaced, reconnect the unit and power it on.
Observe if error code E1 persists. If not, the communication between the indoor and outdoor units should be restored.
Remember, if you feel unsure or are not confident in carrying out any of these steps, it’s recommended to seek the assistance of a qualified professional. If the problem persists, contact the manufacturer’s customer service for further guidance.
