As a household oxygen concentrator, the Yuyue oxygen generator may encounter some common malfunctions during long-term use. The following are common problems, repair methods, and practical cases for reference:

1、 Common faults and solutions

1. Low oxygen concentration (below 90%)

Possible reasons:

The filter cotton or air filter is clogged, resulting in insufficient air intake.

Molecular sieve aging or moisture exposure (exceeding its lifespan).

The flow meter is adjusted too high (the higher the flow rate, the lower the concentration may be).

Pipeline leakage or inadequate sealing of humidification bottles.

Solution:

Clean or replace the filter cotton (it is recommended to check once a month).

Contact to replace the molecular sieve (with a typical lifespan of approximately 15000 hours).

Adjust the flow rate to a reasonable range (such as 1-3L/min).

Check if there is any air leakage at the pipeline interface and humidification bottle.

2. Abnormal increase in machine noise

Possible reasons:

The compressor foot pad is aging or loose.

Dust accumulation or bearing wear on the cooling fan.

Internal pipeline resonance.

Solution:

Check and replace the compressor shock absorber foot pad.

Clean the fan dust or replace the fan.

Adjust the position of the pipeline and fix loose components.

3. Unable to turn on or sudden power failure

Possible reasons:

Power adapter malfunction or poor contact.

The motherboard circuit is damaged (such as overvoltage, moisture).

Solution:

Replace the power cord or adapter.

Contact to check the motherboard.

Check and repair.

4. The float of the flowmeter does not move or bounces

Possible reasons:

Float stuck (affected by dust or water vapor).

Oxygen outlet blockage (high water level in humidification bottle or bent pipeline).

Solution:

Tap the flow meter lightly or remove it for cleaning.

Adjust the water level of the humidification bottle to ensure that the pipeline is unobstructed.

5. Leakage or abnormal bubbles in the humidification bottle

Possible reasons:

The sealing ring of the bottle mouth is aging or not tightened.

The humidification bottle ruptures or the water level exceeds the MAX line.

Solution:

Replace the sealing ring or tighten the bottle cap.

Replace the humidification bottle and control the water level at 1/2-2/3.

6. Machine alarm (such as "E1" and "E2" codes)

Possible reasons:

Pressure sensor malfunction (E1).

Excessive temperature (poor heat dissipation or overheating environment).

Solution:

Power off and restart, check if the heat dissipation port is blocked.

Contact to interpret the code and repair it.

2、 Actual Maintenance Case 1: Insufficient Oxygen Concentration

Phenomenon: User feedback shows that the oxygen concentration of the oxygen concentrator drops to 80% after 2 years of use.

Troubleshooting: Check for severe blockage of the filter cotton and darkening of the molecular sieve color.

Solution: Replace the filter cotton and molecular sieve to restore the concentration to 92%.

Case 2: High operating noise

Phenomenon: The machine starts with a "buzzing" resonance sound.

Investigation: It was found that the compressor foot pad is aging and the internal pipeline is loose.

Solution: Replace the foot pad and fix the pipeline with zip ties, significantly reducing noise.

Case 3: Frequent automatic shutdown

Phenomenon: After running for 30 minutes, the machine stops and the indicator light flashes.

Troubleshooting: The cooling fan is blocked by fluff, causing overheating protection.

Solution: Clean the fan and heat dissipation port, and restore the machine to normal.

Case 4: Insufficient bubbles in the humidification bottle

Phenomenon: Oxygen output is normal, but there are no bubbles in the humidification bottle.

Investigation: The connecting tube of the humidification bottle is bent, and oxygen is not passing through the water bottle.

Solution: Adjust the position of the pipeline to ensure that the airflow passes through the humidification bottle.

3、 Daily maintenance suggestions

Regular cleaning: Clean the filter cotton weekly and clean the humidification bottle monthly (recommended to disinfect with white vinegar).

Environmental requirements: Avoid high temperature and high humidity environments, stay away from walls to ensure heat dissipation.

Usage specification: Before starting up, check whether the flowmeter is reset to zero to avoid prolonged high flow operation.

Accessory replacement: Consumables such as molecular sieves and filters need to be replaced regularly according to the instructions.

4、 Precautions

Do not disassemble the machine by yourself: For repairs involving circuits and molecular sieves, please contact Yuyue.

Safety: Fire is prohibited around the oxygen generator to avoid oil contamination.

Fault alarm: If the fault cannot be resolved, immediately stop the machine and contact the maintenance personnel of the Yuyue oxygen concentrator.

If the problem is complex or involves core components (such as compressors, molecular sieves), it is recommended to use Fish Leap maintenance to ensure equipment safety and warranty rights.
