The fuse is the internal 8Amp slow blow, where the mains cable enters the oven.
It blows about 2 seconds after starting to microwave.
The convector oven and grill work OK (providing that the micowave hasn't blown the fuse first).
THe oven is about 5yrs old but I use it in my holiday home in Spain so it is only used for 15 weeks or so per year.
I am currently in Spain until the end of the month.
Thanks for that. Is there any easy way to identify if the transformer is at fault? Also can I put this conversation on hold until I return to the UK as it will be easier to fix when I am at home. I am quit happy with HV as i was a TV transmitter engineer until my retirement.
If I leave the wires diconnected, will it be safe to use the oven and grill untill I can get the neccessary spares?
Sorry it's been a while but I am back in the UK and have replaced the magnetron. The same problem exists! Every thing else works if I remove the lead to the thermal cutout on top of the magnetron. I would have thought that this would mean the magnetron was at fault. Any other ideas?
Just a thought, should I have disconnected the 2 leads at the bottom of the magnetron? Also would a faulty capacitor show the same effect? I ask because there was no discharge when I shorted it out.
Not sure if you got he last reply as it says Finished.
Thanks for your reply. I'll wait untill I hear from you
Yes to a multimeter.
No the thermal cutout shows continuity so not replaced
OK good, if you measure the resistance between the two terminals of the magnetron filament what resistance in ohms do you get?
Follow that with resistance readings from one side of the filament to the case what resistance do you get there?
0.4 ohms on 200ohm range. Infinity to case 200Meg range
The answer was blank. Could you send it again please?
Ok I'll do that. Do I need to send all the thread so far or just the original question?
