Summer in the Chicago suburbs is no joke — the heat and humidity put extra stress on the appliances your family depends on every day. At Mount Prospect Appliance Repair, we see a predictable surge in service calls every June through August. The good news? Many of these issues have simple warning signs and easy first steps you can take before calling in the pros.
Here are the five most common summer appliance problems we see in Mount Prospect — and what you can do about them.
1. Refrigerator Overworking in the Summer Heat
Why it happens: When outdoor temperatures climb, your kitchen heats up too. Your refrigerator’s compressor has to work much harder to maintain a cool interior, which puts extra strain on the entire unit.
Warning signs to watch for:
- The interior feels warmer than usual, even though the settings haven’t changed
- You notice a loud, constant humming coming from the back or bottom of the fridge
- Your energy bills are creeping up without an obvious reason
A simple tip to try: Pull your refrigerator away from the wall and vacuum the condenser coils — dust buildup forces the compressor to work even harder. Also make sure there’s a few inches of clearance around the unit for proper airflow. These two steps alone can make a big difference.
2. Ice Maker Failures
Why it happens: Summer means more demand for ice, and the heat puts extra strain on the ice maker mechanism. The combination of high usage and elevated temperatures is a recipe for trouble.
Warning signs to watch for:
- Ice production has slowed way down
- The cubes coming out are small, hollow, or misshapen
- No ice at all, even though the freezer seems to be running
A simple tip to try: Check that the water supply line behind the fridge isn’t kinked or partially closed. Make sure your freezer is set to 0°F — anything warmer and ice production suffers. It’s also worth giving the ice maker a quick cleaning to remove any mineral buildup that could be blocking the works.
3. Dishwasher Odors and Poor Cleaning in Humidity
Why it happens: Summer humidity creates the perfect environment for mold and mildew to thrive inside your dishwasher. Trapped moisture and food particles combine to create that unpleasant musty smell — and can leave your dishes looking less than clean.
Warning signs to watch for:
- A musty or sour smell when you open the dishwasher door
- Dishes coming out cloudy or with a filmy residue
- Visible buildup around the door seal or spray arms
A simple tip to try: Clean the filter at the bottom of the dishwasher — it’s often the culprit. Run an empty hot cycle with a cup of white vinegar on the top rack to cut through grease and odors. After each cycle, leave the door cracked open for an hour to let moisture escape and prevent mildew from taking hold.
4. Washing Machine Mold and Odors
Why it happens: High summer humidity accelerates mold and mildew growth inside the drum and around the door gasket — especially in front-loading machines. The result is clothes that smell musty even right out of the wash.
Warning signs to watch for:
- Clothes smell musty or sour after washing
- Visible dark spots or mold on the rubber door seal
- A persistent odor inside the drum even when the machine is empty
A simple tip to try: After every load, wipe down the rubber door gasket with a dry cloth and leave the door open to air out. Always use HE (high-efficiency) detergent in the correct amount — too much soap leaves residue that feeds mold. Run a monthly cleaning cycle with a washing machine cleaner tablet to keep things fresh.
5. AC-Related Stress on Home Circuits
Why it happens: Central air conditioners draw a significant amount of electrical current, especially on the hottest days. This can cause voltage fluctuations throughout your home that put stress on other appliances — refrigerators, washers, and dishwashers included.
Warning signs to watch for:
- Appliance lights flicker or dim when the AC kicks on
- Breakers trip more frequently during hot spells
- Appliances make unusual noises or behave erratically when the AC starts up
A simple tip to try: Plug sensitive appliances into surge protectors to guard against voltage spikes. If you’re experiencing frequent breaker trips or flickering, it’s worth having a licensed electrician take a look at your home’s circuits — this is a safety issue that goes beyond appliance repair.
