Understand the Refrigerant Cycle
Refrigerant is present in many appliances, including heat pumps, air conditioners and refrigerators, so it's important to understand the refrigerant cycle, how it works, and what can go wrong. And this guide will help you understand the path refrigerant takes and how the evaporator, compressor and condenser all work together. This makes it much easier to do home appliance repair and find specific problems when one of these components slows down or starts malfunctioning. So you can know what sort of maintenance your fridge needs and when it may have a refrigerant leak or similar problem.

Buy a Good Multimeter
How do you know if a problem is in the appliances's wiring? You test it! And for that, you need the right tool. Purchase a multimeter that allows you to measure voltage and other important signals that show you which wires or electrical components aren't working. If you want to become a master of home appliance repair, you need a multimeter and always be sure to take proper safety precautions.

Check Ignition Processes
If you have gas-powered appliances, they depend on an ignition process to get started. And some have electric starters and some have pilot lights, but either way this is a common source of problems in otherwise highly durable appliances. Check your ignition process and make sure the pilot light is on, the starters are properly aligned, and that nothing has been blocked with soot.
