check tension spring on door

It is micro switch when you close the door, the door latch push in a button on the micro switch take lid off open and close the door and see if you can spot a button not popping out properly or the latch not in line with the switch

This could be the upper latch in the door. Mine stopped working just as you describe. After dis-mantling I noticed the mechanical action which should operate 3 micro-switches in the door lock was not working correctly on the upper switch when the door was closed.

This is part of the safety interlock circuit to prevent operation of the magnetron when the door is open.

Closer inspection of the door striker arm revealed a crack which allowed the top part of the arm to spring away from the upper switch which stopped the oven working.

This part is easily removed by prising the door inner trim off gently, starting at the bottom was easiest for me, then sliding the arm up against the spring tension until it slides clear of the guide grooves, finally detach the spring.

I have no idea where to get spare parts for this ASDA only branded product, so I am going to use super strong epoxy resin to repair the striker arm.

see this causes and fix it. God bless you

Do not pry the door open since there is an easier remedy which will lead you in the direction that you need to fix your problem. Take the cover off after you disconnect the power to it. Once you have taken the cover off (only a few screws) you will be able to see the two latches that hold the door closed and the link that opens both of them. You can just lift both latches at the same time and it will open. After you have done that take a good look and press in on the open door button and you will see where you have the problem of the door hanging. That button should push a linkage that pushes up on both latches at once to open the door. It is spring loaded so that it comes back down so that when you close the door it will hold the door close.You need to take the cover off the microwave so that you can pull both of the latches that hold the door closed up.

The microwave has a safety door switches (2-3 micro switches)
The door mechanism should hit these micro switches. If you can open the machine, you can see that these micro switch has a holder that you can adjust and tighten to make sure that the hook of the door should activate them.

In most cases this is due to a broken door opening lever or loose or broken door latch / hook parts. They can only be accessed and examined if the cover is removed from the microwave. In many over the range models, you can access the door parts by removing the control panel assembly. Sometimes you may be able to get it open by pushing up gently on the bottom of the door while pushing the button, in case you need to empty it.
