Thermostat Fault Oven

A dead built in over was brought back to life. Model: Delonghi. My cousin brought this built in for repair. My cousin has a hobby that he loves to cook and he uses this oven to satisfy he food desires.  The oven was completely dead and needed an urgent repair to bring it back to life.

It is a used oven but worked many years for him and he wanted it to be fixed as soon as possible.

I took the top cover off hoping to find a thermostat/fuse but there was nowhere to be found in that area.

I found the main program IC, two relays, one capacitor and one alarm buzzer, two resistors and of course the main display. I know it suppose to have one but I did not know when till I started thinking straight.

When the common sense was activated in my brain I was able to locate the part I was looking for which will be where the main power cord was suppose to be.

Finally I could see it and next to it was a cooked cockroach, Yuk. The moment I touch that cooked cockroach with a screw driver, it fell like dust.

The blue part is the main thermostat/ fuse and usually that is a main problem why some devices do not come on.

I found similar parts in the microwave ovens as well.

This is a 120 C degree thermostat and fuse (usually 10 amps) at the same time. As expected, it was open and needed replacement.

I replaced it with the same specs part that I have plenty of in my shop and powered up the oven.

As expected, it came on. My cousin promised me a juicy meal as in return for this easy repair so I am expected to get paid soon.

Mission Accomplished.

    Cockroach turned to Cookedroach. Without mentioning the meaning of the four letters alone before the roach part.(lol)
    My brother also uses Delonghi devices at his home for making coffee. I believe it is a product from Italy.
