If you have a GE freezer, you may have noticed a feature called Frost Guard or Adaptive Defrost. This is a smart technology that helps your freezer defrost only as needed, reducing frost buildup and freezer burn. But how does it work and what are the benefits of having it? In this post, we will explain what Frost Guard technology is and how it keeps your freezer fresh and clean.
Frost Guard technology is a system that monitors the usage and conditions of your freezer and adjusts the defrost cycle accordingly. It accounts for door openings, compressor run times, and defrost heater operation to determine when and how long to defrost. This way, your freezer only defrosts when it is necessary, saving energy and preserving your food quality.
How Frost Guard Technology Works
- Frost Guard technology works by using a main control board that collects information from various sensors and components in your freezer. The main control board uses this information to decide when to initiate the defrost cycle and how long to run it. The defrost cycle consists of five phases:
- Cooling Operation: During this phase, the main control board monitors the door openings and the compressor run times. The more the door is opened or the longer the compressor runs, the sooner the defrost cycle will start.
- Pre-Chill: When the main control board determines that the defrost cycle is necessary, it forces the freezer into a continuous cool mode. This lowers the freezer temperature before the defrost cycle begins, allowing the freezer to return to its set temperature faster after the defrost cycle is over.
- Defrost Heater Operation: The main control board turns off the compressor, condenser fan, and evaporator fan. It then turns on the defrost heater, which is located near the evaporator coils in the back of the freezer. The defrost heater melts any frost or ice on the coils and then turns off. The main control board monitors the evaporator temperature using a thermistor and terminates the defrost heater operation when it reaches a certain level. A typical defrost cycle lasts 20 to 30 minutes.
- Dwell Period: After the main control board terminates the defrost heater operation, it initiates a five-minute dwell period. During this period, the compressor, condenser fan, and evaporator fan remain off. This allows any remaining frost or water to drip and drain from the coils.
- Post Dwell Period: The post dwell period is designed to cool the evaporator before circulating air within the freezer. The main control board turns on the condenser fan and waits for two minutes before turning on the compressor and evaporator fan.
Benefits of Frost Guard Technology
- Frost Guard technology offers several benefits for your freezer and your food, such as:
- Energy efficiency: By defrosting only as needed, Frost Guard technology reduces the energy consumption of your freezer and lowers your utility bills.
- Food quality: By minimizing frost buildup and freezer burn, Frost Guard technology preserves the texture, flavor, and nutrition of your frozen food.
- Convenience: By eliminating manual defrosting or excessive frost removal, Frost Guard technology saves you time and hassle.
FAQs
Q: How do I know if my GE freezer has Frost Guard technology?
A: You can check if your GE freezer has Frost Guard technology by looking at your owner’s manual or visiting the GE Appliances website. You can also contact GE Appliances customer service for assistance.
Q: How often does my GE freezer with Frost Guard technology defrost?
A: The frequency of defrosting depends on how you use your freezer. Generally, your GE freezer with Frost Guard technology will defrost every 12 to 48 hours.
Q: How can I maintain my GE freezer with Frost Guard technology?
A: You can maintain your GE freezer with Frost Guard technology by keeping it clean, level, and well-stocked. You should also avoid opening and closing the door too often or too quickly.
