You get "fuses" when you turn on the microwave, sometimes yes, sometimes no, and you want to know why it happens.
Would you like to know why it happens and how to fix it?
This fault is as typical and as popular as the day of the Holy Innocents.
Who hasn't had the light go off when turning on the microwave?
How many of us haven't thrown away our not-so-old microwave thinking that it was a major fault?
I'm going to tell you briefly what this fault is, which is nothing more than a totally intentional bad design that hasn't progressed over many years.
There is no standard and elegant solution for this, other than to undergo the mandatory replacement of the hooks.
And with the consequent expense and that will be a start over with the same plan.
It also involves a delicate and forced operation, which does not always leave the door in perfect condition.
You can also convert this system, dismantling everything and removing all the hooks.
Making a single button activate several relays (all those necessary according to the circuits to be managed)
That is, when opening and closing the door, 2 or 3 relays are managing these circuits at the same time.
The supposed risk of having your head near the magnetron unconsciously is quite unlikely, in addition to the fact that we would notice other things, such as the rotation of fans, noises from the magnetron, etc.
Rarely would a relay It will break down in the short term, and very rarely out of 2 or 3 relays one will break down causing the strange consequence of the magnetron working with the door open and outside the electronic program of the microwave panel.
What I did was design a magnetic closure, where the magnet attracts the door and keeps it closed, and the door presses a fairly light button.
And this button activates and deactivates 2 relays simultaneously.
This is the relay I used (it's 2 relays in one):
This is what the microwave chassis looks like.
Here in the gaps you could see some plastic that acted as a ramp so that the hook could go up as it was inserted.
Now you can see a normal button in the gap above, and in the gap below there is nothing now.
And this is how the microwave door finally looks.
There are several neodymium magnets installed inside the door.
They can't be seen because they are inside.
And I have used adhesive tape to cover the holes that were there for the hook holder.
