i've done it again!

[maffa ent]

evening all!

i've gone and got involved in a cooker repair again!

customer called me to say rcd was tripping. i turned up, tried resetting it, but it wouldn't reset until i'd switched off mcb's, and then it would.

switched on mcb's one by one, and all power restored.

i then tried to make it trip again, and succeeded when i switched on a particular cooker ring.

so, i then tried the other rings, all ok. tried this faulty? one again, and trip!

disconnected said ring, tried controls, all ok, no problems.

i then replaced this faulty? ring, and all worked ok - for a few days!

now it's tripping out again! should i be looking into it being a fault on the controls?

or possibly a faulty new element? i am gonna ir test the old one tomorrow, which i didn't do before i replaced it!

thanks in advance!

Hi,

Totally agree, it needs a good warm up followed by a test.

Regards.

Take a look at the coocker connection unit, and the isolator.
I had a cooker recently, that whilst one of the rings were faulty, there was also a neutral at the isolator that had been caught by a screw.

Have seen burnt out crimps on the element before - they can loosen when you pull them off and put them back on the new element.

As an aside, did you IR test (lives to cpc) the cooker - you should really have done after any repair along with the cpc continuity test.
