A broken control knob might also leave the freezer too warm. If the temperature stays above the safe freezing level, your food will start to thaw slowly. Frozen meat might soften, vegetables will lose their crunch, and ice cream will melt. Worse, bacteria can start to grow in partially thawed food, creating potential health risks.
You’ll often notice signs such as a strange smell, soft food textures, or even small puddles of water forming in the compartment.
3. Impact on the Refrigerator Section
Many modern refrigerators share cooling systems between the freezer and fridge compartments. That means a faulty freezer control knob can also disrupt the refrigerator’s temperature.
If the freezer overcools, the fridge section might freeze your produce and beverages.
If the freezer is too warm, the fridge could lose its cooling power, causing milk and leftovers to spoil faster.
In either case, both food safety and appliance efficiency suffer.
4. Higher Energy Bills and Shorter Appliance Lifespan
When the temperature knob fails, your refrigerator’s compressor compensates by running longer and harder to stabilize the temperature. This continuous strain increases energy consumption and accelerates wear and tear on internal components. Over time, you’ll not only spot higher electricity bills but may also face expensive repair or replacement costs.
