As temperatures in the Phoenix area begin their annual climb toward triple digits, your appliances face their toughest test of the year. Proper preparation can prevent costly breakdowns during the months when you need your refrigeration most.
Clean Condenser Coils
Dusty condenser coils force your refrigerator to work harder, especially in hot weather. Before summer arrives, pull your refrigerator away from the wall and carefully vacuum the coils. For built-in units, access panels are typically located at the bottom front or back of the unit.
Check Door Seals
Arizona's low humidity accelerates the deterioration of rubber door gaskets. Inspect seals for cracks, gaps, or areas that don't make firm contact. A simple test: close the door on a dollar bill - if it slides out easily, your seal may need attention.
Verify Temperature Settings
Your refrigerator should be set between 37-40 degrees Fahrenheit, and your freezer at 0 degrees. During summer, you may need to adjust these slightly cooler to compensate for increased ambient temperatures.
Ensure Proper Ventilation
Built-in refrigerators require adequate airflow around condenser coils. Check that vents aren't blocked and that there's sufficient clearance per manufacturer specifications. In extreme heat, inadequate ventilation can cause compressor overwork and failure.
Ice Maker Maintenance
Phoenix hard water creates mineral buildup in ice makers. Clean the ice maker system and consider a water filter if you notice cloudy ice or reduced production. Summer is when ice demand peaks, so ensure your system is ready.
Conclusion
A few hours of preventive maintenance before summer can save you from emergency repairs during the hottest months. If you notice any issues during your inspection, address them promptly before the heat arrives.
