Today, we're going to delve into the heart of your chilly magic box. Just about as exciting, right? So, put your woolly hats on and let's dive into the ice-cold depths of your refrigerator's defrost thermostat!
Chipping off the Ice: What is a Defrost Thermostat?
Wrapped up in puffy insulation jackets, hanging out calmly in the stifling confines of your freezer like a hermit in a snowstorm is our friend, the defrost thermostat. Its mission? Only to keep your freezer humming like a winter lullaby and stop it from turning into Antarctica. Technically speaking, the defrost thermostat, as part of your fridge's defrost system, is a bimetallic thermostat that regulates the control of your refrigerator's electric heating elements.
When the temperature within your freezer rises above the designated temperature (usually around 20°F), the defrost thermostat triggers the defrost heater to melt away any excess frost. Cooling must go on!
Whirlwind Love: The Relationship Between Your Fridge and its Defrost Thermostat
Your refrigerator's defrost thermostat, like a devoted partner, is there to protect your fridge by preventing excessive temperatures during the defrost cycle. It's that vigilant day-and-night watchman, always ensuring that your ice cream doesn't turn into warm goo. Without a functioning defrost thermostat, you’re cruising towards a frost-laden freezer threatening to turn your popsicles into icicles!
Spot the Cold-Shoulder: When is a Defrost Thermostat Failing?
Even the most reliable of chums can occasionally falter. Here are signs that your defrost thermostat might be giving your fridge the cold shoulder:
- Your fridge or freezer is too warm - A possible sign that your unit isn’t defrosting properly
- Your refrigerator is freezing food - ah, the mystery of the frozen milk.
- Your fridge is running non-stop, working overtime and still failing to keep its cool.
Remember, the beauty of being a DIY'er is you can check this out yourself! An uncomplicated test using a multimeter (set to the lowest setting for Ohms of resistance) can quickly show whether the defrost thermostat has blown cold on you.
