Pat Testing Whirlpool Freezer.

[Pete999]

Whirlpool chest freezer. Earth bond to compressor. No earth bond to casing.
Contacted Whirlpool for clarification and got reply as follows:-

"Dear Mr Dunbar

Thank you for contacting Whirlpool UK

Regrettably I am unable to offer you any technical resolution and would only recommend for a Whirlpool
engineer to attend and diagnose.

I am sorry we were unable to be of any more help at this time.
Regards"

Wouldn't you have thought that the Whirlpol itself would be able to advise on this. I think even the COP 4th Ed, also recommends contacting manufacturers on issues.

Anyone help with matter of no earth bond detected with casing please?

Does the freezer pass the PA Test?

The advice I received in a similar situation was to do an IR test from the earth to the exposed metal. I can't remember the limits, but if the value is sufficiently high I don't believe it needs to be earthed.

I asked because I was doing an EICR and could find no earth continuity between the RFC CPC and the exposed metalwork of the fridge/freezer, but there was continuity to the compressor cradle at the rear of the unit.

Is this somewhere I can reference to as there is no class 2 symbol and a metal case and COP regs would mean a class 1 earth. I'm sure the IR would show it to be safe enough but I need to make sure I'm covered by regs I can show.

I don't know, I thought someone had mentioned a figure in my thread on the subject, but I checked it and there wasn't, sorry.
