Fridge guard protector 9801 protects the refrigerator circuit, prolongs the life of the refrigerator, and avoids greater losses caused by failures. It can ensure that the refrigerator works normally under unstable voltage conditions, and has the characteristics of small size, light weight, low cost, simple structure, and energy saving.
1. Use a high-joule surge protector
Recommended specifications: match the "starting current peak" of equipment such as refrigerators to avoid overload tripping of the protector. Choose a model with "high absorption capacity" to give priority to the protection needs of large household appliances (such as refrigerators and air conditioners).
Installation location: plug directly into the wall plug and avoid using extension cords.
2. Ensure that the grounding system is reliable
Check whether the refrigerator plug and the household circuit are effectively grounded (grounding resistance ≤ 25Ω).
For old houses, it is recommended to contact an electrician to detect and upgrade the grounding wire.
3. Short-term emergency measures
When a thunderstorm warning is issued, unplug the refrigerator (empty perishable food in advance).
Use a lightning protection socket for temporary protection.
4. Install a voltage protector
Choose an independent protector that adapts to the refrigerator's power and installs it directly to the main wall plug circuit.
Make sure there is no extension cord between the protector and the refrigerator, and the plug is in firm contact.
Applicable electrical appliances
✅ Refrigerators, air conditioners, TVs, computers, and other equipment with precision circuits.
⚠️ Limitations
High-power electrical appliances (such as air conditioners) need to match the current rating of the protector (≥15A).
Protectors with too low joules may not be able to absorb multiple surges.
No negative effects
The surge protector is only activated when the voltage is abnormal, and it is in a direct-through state during normal operation, which will not interfere with the operation of the compressor.
On the contrary, it can prevent surges from causing damage to the control board (indirectly protecting the compressor).
Precautions
Regularly replace aging protectors (every 3-5 years or after a large surge).
Avoid using inferior protectors to cause voltage instability.
| Connection method | Applicable scenarios | Advantages and Disadvantages |
| Directly plug into the wall | Areas without lightning risk | ✅ Simple and reliable; ❌ No surge protection |
| Surge protector | Areas with lightning/voltage instability | ✅ Surge protection; ❌ Need to be replaced regularly |
| UPS (uninterruptible power supply) | Frequent power outages and need to maintain refrigeration | ✅ Surge protection + short-term power supply; ❌ High cost, need to match power |
Economical solution: surge protector + regular maintenance.
High-reliability solution: whole house SPD + single device protector.
Extreme risk area: superimpose UPS, and give priority to protecting expensive medicines or experimental sample refrigerators.
Summary: During the rainy season lightning strikes, equipping the refrigerator with a surge protector of more than 2000J and ensuring reliable grounding can effectively reduce the risk of surge damage by more than 90%. Long-term use will not damage the compressor, but it is necessary to avoid using inferior or over-service protectors.
