My proline st44 microwave just suddenly went dead. I?ve checked and changed all fuses on the microwave and leads. It comes back again and then goes dead again. The inside door mechanism seems to be intact...
ProLine ST44 950 Watts Microwave
Since this machine is only sold in the UK I do not have a picture to point you to.
The problem is probably a blown thermal fuse. This fuse is located inside the machine and is for detecting overheating and fires. Sometimes age will cause it to fail. It's generally located near the air vent outlet.
If you handy with fixing gadgets you can check it.
Unplug the machine and remove the cover.
You can take an ohmmeter and test it. If it shows open you can replace it. It may be soldered in I am not sure. You can get replacements at an appliance parts store or Radio Shack®. There may be conventional fuses inside so you can check them also.
If nothing else is wrong it might be a door switch problem.
Wear on the interlock causing the crowbar microswitch to short the line and blow
the internal line fuse. The interlock, required by law, contains 3
switches - one switch sends a door-open signal to the
microprocessor, one opens the line and the third crowbars (shorts)
the power leads to the magnetron. If the crowbar switch activates
before the line switch opens, the line fuse gets blown. Just toss the crowbar switch.
