Repairing Common Home Appliances
Refrigerators
Refrigerators are essential for preserving food, but they can develop various issues over time.
Common Problems and Solutions
- Not Cooling Properly
- Check the Thermostat: Ensure it is set to the correct temperature. If it’s malfunctioning, it may need replacement.

Washing Machines
Washing machines are complex appliances with various components that can fail.
Common Problems and Solutions

- Leaking Water
- Examine Hoses: Loose or damaged hoses can cause leaks. Tighten or replace them as necessary.

Dishwashers
Dishwashers are designed to simplify the dishwashing process, but they can encounter issues.
Common Problems and Solutions
