Microwave is Smoking

Microwave is Smoking - Appliance Repairs in Port Elizabeth
Smoking is Bad for your Health especially when its your Microwave is Smoking.

Andre from Cradock contracted me recently because he has installed a new Magnetron in his LG Microwave but it is still smoking when he switches it on.

There are a couple of reasons why you microwave are smoking
1.It could just be food that is logged somewhere inside the cabinet and is been overcook every time you switch on the Microwave oven on or
2. A loose terminal connection on your interlock switches
3. Transformer busy packing up,

Most of the times when you smell burning of plastic and see smoke it’s your High Voltage Transformer and for the sake of Andre’s dilemma I will only be chatting about the his high voltage Transformer.

High Voltage Transformer

The main reason for a transformer to start shorting out (smoking) is;
• Power surges (electronic rust)
• Old age (the transformer)
• Faulty High Voltage Capacitor

Once the High Voltage Capacitor goes faulty ir starts shorting out - causes extra strain on the transformer by drawing excessive current and the winding starts heating up and once the insulation around the wires start to melt is starts to smoke.
This little bugger is very devious because it gives the appearance that it is the transformer - shorting out. Also when you test the High Voltage Capacitor it check out fine but as soon as you turn your back it does the same again.
Just replace the High Voltage Capacitor and High Voltage Diott
If you catch this situation in time, then your Transformer should be fine but because we are not always turned into the negative side of our Appliances and we don’t always realize things are busy going wrong - until it is too late.
