1. Gas Depletion Warning: Your refrigerator is signaling it's running out of gas; replace it before issues arise.
Additionally, to prevent the risk of refrigerator explosions, it's advisable not to use excessively old refrigerators refilled with gas multiple times.
1. Recognizing signs of a refrigerator running out of gas
- The refrigerator lacks gas or has a gas leak, leading to prolonged cooling time (compressor runs continuously without stopping).
- The refrigerator doesn't cool well, has weak cooling, or takes a long time to cool.
- The suction line to the compressor does not condense dew.
- Reduced current through the refrigerator due to weak load.
Testing a gas-depleted refrigerator:
Use a matchstick to identify gas depletion (never use a lighter):
Ignite the matchstick and hover it over the end of the condenser coil (while the system is operational). If the heated coil becomes too hot, the refrigerator is low on gas; if the refrigerator has enough gas, the substance (gas) will evaporate, cooling the heated coil quickly.
Use soap bubbles:
Activate the compressor, then apply soap to the suction line, condenser coil, and evaporator coil. If soap bubbles appear, it means the refrigerator has a leak, usually found in the evaporator coil.
Oil leakage:
Wipe the refrigerant line and coils clean, activate the compressor, and observe on the lines and heat exchange coils. If you see oil streaks, it means the refrigerator has a hole.
2. Causes of a refrigerator depleting gas quickly
Coil corrosion:
Older refrigerators are prone to this issue. Tiny coil corrosion holes release gas slowly, making it difficult to detect early. Only when the refrigerator weakens or runs out of gas do we notice.
Weld joint gaps:
Due to the production process, weld joints may not be airtight or secure, leading to gas leakage over time. It could also be a result of previous repair issues causing gaps in the weld joints.
Strong Impact:
While rare, significant collisions or intense vibrations during transportation can still cause gas leakage in the refrigerator.
Coil Puncture:
Almost always, the primary cause of refrigerator gas leakage is when customers attempt to break in, puncturing the evaporator coil. Gas will escape through the hole, causing a loss of gas.
3. Some considerations when replacing refrigerator gas
If your home refrigerator is old, avoid replacing the gas or tampering with internal components. Instead, call a refrigerator repair center to replace the gas or weld any damaged areas. Incorrect gas refilling or welding techniques can lead to residue buildup in the pipes, causing blockages and posing a risk of explosion.
Additionally, to prevent the risk of refrigerator explosions, it's best not to use overly old refrigerators refilled with gas many times because the extent of refrigerant leakage can easily lead to gas pipe leaks and electrical short circuits.
