Hiya,

Can you post the make and model number of the appliance please?

By main fuse, do you mean it's tripping the RCD?

.

Thanks

BELLING XOU90FP MODEL NUMBER XXXXXXXXX SERIAL NUMBER 81114409 YES THE MAIN FUSE IN THE FUSE BOX 30AMP

Expert:  Techdesk replied 4 years ago.

Hiya,

OK, I need to know if it's a fuse (the ones you rewire) and RCD (trip switch marked RCD) or an MCB which will be marked differently.

.

If it was the main fuse, you would need your supplier out to replace it as it's a sealed unit.

.

Thanks

SORRY - NO - IT'S THE 30AMP CARTRIDGE FUSE IN THE FUSE BOX IE THE COOKER CIRCUIT FUSE THAT BLOWS

Expert:  Techdesk replied 4 years ago.

Hiya,

OK, that's a short circuit to take out a fuse.

.

Do you have, and can you use, a multimeter?

.

You say it was switching off and on normally, I assume you mean it was in use at the time it blew?

.

Isolate the power to the appliance.

Take the rear panel inside the main oven out.

(if there's a light fitting, take the glass out first).

.

Is the element obviously damaged?

.

Thanks

O.K THANKS IS IT FAIR TO ASSUME THAT YOU THINK IT IS THE ELEMENT AT FAULT I'M NOT IN A POSITION TO GET THE PANEL OFF AT THE MINUTE PROBABLY TOMORROW NOW BUT YES I CAN GET A MULTI METER AND YES THE OVEN WAS WORKING AT THE TIME

Expert:  Techdesk replied 4 years ago.

Hiya,

No problem, just check it when you can and come back to let me know.

.

I think the element is the most likely cause of the problem.

If there's no visible damage, take the element out and check it with a multimeter to see if it's open circuit.

.

Check it out and let me know what you find.

.

Thanks

Hi - yes no problem i'll do that tomorrow


many thanks

Expert:  Techdesk replied 4 years ago.

Hiya,

No problem.

Thanks

Customer: replied 4 years ago.

Bye for now !!

Expert:  Techdesk replied 4 years ago.

Hiya,

No problem.

I'll hear from you once you've checked the element.

Don't reply, as it locks me to your question.

Wait till you've got news of the element.

.

Thanks
