TV voltage protector and a refrigerator protector (or fridge guard) are similar in that both are designed to protect electronic appliances from power surges, voltage fluctuations, and electrical issues. However, they are typically designed with different types of appliances in mind, and there are a few key differences that determine whether a TV protector can work for a refrigerator:
TV voltage protector vs refrigerator protector key differences:
Power Requirements:

Refrigerators generally require more power and have a large compressor motor that turns on and off, creating power surges.
TVs, on the other hand, have lower power consumption and don’t have large motors that create voltage spikes when turning on or off.
Type of Protection:

TV voltage protector is designed to handle smaller, more sensitive electronic components and protect against minor fluctuations that could damage circuits in a TV.
fridge protector is typically designed to handle larger voltage fluctuations and power surges that could damage the compressor or other critical components in a refrigerator.
Delay Function:
Some fridge protectors have a built-in time delay to prevent the refrigerator from restarting immediately after a power failure, which could potentially damage the compressor. This delay ensures the compressor’s pressure stabilizes before restarting.
Most TV protectors do not include this feature since TVs don’t have a compressor and are less affected by this kind of issue.
Conclusion:
TV voltage protector can provide some protection to a refrigerator, but it may not offer the same level of protection that a dedicated fridge protector would, especially when it comes to handling power surges and fluctuations that affect large appliances like refrigerators.
If you’re specifically concerned about your refrigerator’s safety, it’s best to use a fridge protector designed for that purpose, as it can address both voltage fluctuations and the compressor’s operational characteristics more effectively.
So while it might work in some cases, using a fridge-specific protector is a safer choice to ensure your appliance remains protected.
