I get it, not all of us are, and not all of us think we have what it takes to fix an electrical appliance. However, the truth of the matter is that it is quite simple, and with the masses of info available on the internet, you have some of the world’s best teachers available. This, along with the right appliance parts, can save you lots of time and money.
When it comes to your broken microwave, it is too easy to call a repairman or just go and buy a new one, but where would be the fun in that? If you think about it, the worst thing that can happen is that you cannot fix it. On the other hand, the best case scenario is that you could have it working as good as new for a fraction of the cost.
How to make an old microwave work
The first thing that you want to do is to remove all the moving parts. You might lose a plate or turner if you decide to leave it in.
The second thing that you need to do is to unscrew the back panel and open up the machine. Once the back panel is removed, you can start the process of elimination which is step three. Seeing that there are a couple of elements in a microwave that can break, you need to go through the whole machine systematically.
Generally, you want to start with the most inexpensive parts that you can replace. Use a resistor tester (which you can find at any hardware store) to test the fuse first. If it shows a reading of infinity, then you need to replace it. If your fuse is still in working order, you need to continue exploring the other appliance parts that may be faulty.
The next microwave part that you need to look at is the switch. Most microwaves have three switches, and if any one of these switches breaks, you need to replace them. When you inspect your switches, you will be able to see if it closes the circuit or not. If no clear contact is made once the switch is pressed, no electricity will flow through. Luckily, these switches are very cheap and easy to replace.
Each switch will have a make and model number which can be found on the casing. This makes it easy to order online or go to a repair shop and buy a spare.
Time to test
Once your new switch is installed, you can test it by plugging it in and heating up your leftover pizza from last night. What could have cost you a couple of hundred dollars, will only set you back about $5 if the switch is the problem.
The main thing to remember when working with electrical appliances is that they work with electricity. It is a fairly simple task to trace the flow of electricity, and if you cannot find the problem in this way, then you can start looking at the other components. In the end, replacing a component will always be cheaper than replacing the whole machine.
