Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
First, just use your eyes and ears. Watch the appliance run and listen for specific noises. Look for visible dirt, damage, or leaks.
Step 2
Unplug the unit. Then, check the common clog points: the dryer vent hose, the refrigerator coils, and the dishwasher filter at the bottom of the tub.
Step 3
Consult the user manual for the recommended maintenance schedule and location of key components.
Step 4
Perform a simple performance test, like checking the temperature of your oven or fridge with a separate thermometer.
Step 5
Examine all power cords and water hoses for signs of fraying, cracking, or bulging.
Step 6
If you know how, use a multimeter to check for continuity on components like fuses or heating elements, but only if you're 100% confident in what you're doing.

When to Call a Professional Appliance
- If you smell gas or are dealing with a gas appliance repair. Don't take chances.
- When you suspect a major electronic component like a control board has failed.
- If the repair involves the sealed refrigeration system (compressor/refrigerant) or a major mechanical part like a washer transmission.
- When dealing with high-voltage components (240V) in ovens or dryers and you're not an expert.
- If the appliance is still under warranty; attempting a DIY repair will likely void it.
Prevention Tips
- Clean your dryer's lint screen after every single load, and clean the entire vent pipe once a year.
- Vacuum your refrigerator's condenser coils at least once a year, or twice if you have pets.
- Rinse out your dishwasher's filter once a month to prevent clogs and odors.
- Avoid overloading your washer and dryer to reduce strain on the motor and belts.
- Inspect your washing machine's water hoses annually and replace them every 3-5 years, preferably with braided steel lines.
