Hey there, friends of extreme coolness! I bet you are already asking, "You're not about to teach us how to defrost a turkey, are you?" Well, not quite! 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.
