Are your household appliances acting up again? Before you immediately call for professional appliance repair, you may be surprised to learn that many of the most frequent appliance problems have simple solutions you can try yourself. With some basic troubleshooting and careful attention, you can often bring your machines back to working order, saving both time and money. Below we’ll walk through ten of the most common household appliance issues, step-by-step solutions you can attempt on your own, and the situations where it’s best to turn to Prostar Appliance Service — your reliable appliance repair experts in Irvine, CA.

1. Refrigerator Not Cooling

Possible Cause: Dirty condenser coils, incorrect temperature setting, or a faulty thermostat.
Solution: Unplug your refrigerator, locate the condenser coils (often at the back or beneath the unit), and carefully clean them with a vacuum or soft brush. This alone can drastically improve cooling performance. Double-check that your temperature dial hasn’t been accidentally adjusted. If your food still spoils too quickly or your fridge continues to run constantly without cooling, it may be a failing thermostat or compressor. That’s when calling our refrigerator repair professionals is the safest bet.

2. Dishwasher Not Draining

Possible Cause: Blocked filter, clogged hose, or an obstructed air gap.
Solution: Start by removing the bottom rack and cleaning the filter, which can collect food debris and grease. Inspect the drain hose for clogs or kinks, and flush it with water if necessary. Running a hot cycle with vinegar and baking soda can also dissolve grease buildup. If the dishwasher still leaves standing water, that usually indicates a pump or sensor issue, which requires professional appliance repair attention.

3. Dryer Not Heating

Possible Cause: Clogged vent, blown thermal fuse, or worn heating element.
Solution: Always clean the lint trap after every load, and check the dryer vent hose for lint or blockages that restrict airflow. If clothes remain damp after multiple cycles, the thermal fuse may have blown or the heating element may be burned out. While replacing these parts can sometimes be DIY, it often involves electrical work, so most homeowners prefer scheduling a professional dryer repair service.

4. Oven Not Heating Properly

Possible Cause: Burned-out heating element or faulty oven thermostat.
Solution: Turn off the power, remove the heating element, and look for visible breaks or burns. Replacement parts are widely available online and can be installed with basic tools. If the oven continues to underheat or overheat after replacement, the thermostat or control board may be the culprit. In that case, our dedicated oven repair team can restore accurate temperature control.

5. Washing Machine Not Spinning

Possible Cause: Overloaded or unbalanced drum, or a defective lid switch.
Solution: Try redistributing laundry evenly and running a smaller load. Many washers will refuse to spin if they detect imbalance. If that doesn’t work, the lid switch may be broken, preventing the machine from entering the spin cycle. Replacing it requires accessing the control panel, a task many homeowners prefer to leave to washer repair technicians.

6. Microwave Not Working

Possible Cause: Blown fuse, tripped breaker, or faulty door switch.
Solution: Always unplug the microwave before inspection. Check the power outlet first, then look for a blown fuse inside the microwave. The door switch is another common failure point. Because microwaves contain high-voltage components, many DIYers stop here and call microwave repair specialists for safe service.

7. Refrigerator Water Dispenser Not Working

Possible Cause: Frozen water line, clogged filter, or faulty inlet valve.
Solution: Shut off the water supply, defrost any ice blockages in the line, and replace the water filter if it hasn’t been changed in the last six months. If water still won’t flow, the inlet valve may need replacement — a common repair our refrigerator technicians handle quickly.

8. Freezer Door Not Sealing Properly

Possible Cause: Dirty, cracked, or misaligned door gasket.
Solution: Clean the gasket with warm water and mild soap to remove food residue. If the gasket is torn, warped, or hardened with age, replacement is necessary. A strong seal keeps cold air in and prevents frost buildup. If frost still develops, freezer repair professionals can diagnose hinge or alignment issues.

9. Food Freezing in the Wrong Areas of Fridge

Possible Cause: Malfunctioning thermostat, blocked air vent, or improper settings.
Solution: Make sure your fridge temperature is between 37–40°F. If produce drawers still freeze or items near the back turn icy, blocked airflow or a defective thermostat may be to blame. Professional service ensures your fridge maintains consistent cooling without wasting energy.

10. Coffee Maker Not Brewing

Possible Cause: Mineral scale buildup or blocked tubing.
Solution: Run a cleaning cycle with equal parts vinegar and water, followed by two fresh-water cycles. Descaling solutions are also effective. If the coffee maker still won’t brew or makes loud noises, an internal pump may need replacement — a job for specialized repair.
