2 week old fryer fail

[McTadder]

Still on a learning curve and need a bit of advice.

I had a chip fryer fail today passed the earth but then failed insulation on 500v setting class 1.
It’s only 2 weeks old. Fryer next to it passed fine. Then a pizza oven had the same problem!!

Any advice appreciated... well most of it ?

Are they in regular use at the moment.

2 weeks old? send it back under warranty.

did you test L-N with the thing turned on? youll be reading the element.

 

[McTadder]

Yes they’ve been used. Not much though recently. Is it to do with a temperature suppressor? Read that doing the test at 250v might work.

Sorry don’t get the L-N with it turned on. Do you mean the IR test. I’m using a seaward 500+ Apollo FYI

PAT testers connect L and N together, then test between this and earth.

That’s the IR test isn’t it

Yes. That's the one you said it failed right?

How much of a fail? I.e. what sort of IR result did it find?

It is not uncommon for heater elements in ovens to be troublesome for tripping RCD due to leakage if unused for a while and moisture absorbed, but they usually clear if run up to temperature (which can be problematic if the RCD keeps tripping...)

 

[Lucien Nunes]

As above, sheathed heating elements can absorb moisture with disuse although new appliances are usually OK. When warmed up, the IR value tends to fall rapidly, then slowly rise back to and beyond the initial reading. Need specs and readings to comment further.

What reading are you getting?
Does it improve running it for a few minutes?

What does the earth leakage test show? Load?
