Switch all power off from the mains

Check you have switched it off

If possible pull out the suppliers fuse, against the regs but who
cares if it was broken by the last electricity board bloke who was
there last year.
Check you have done all that again.


I'll have a play later today. I understand a fair bit about 'lectrics but I
do thank you for your concern and for the sensible safety advice.

Disconnect the heating element from the controller and put an ohm
meter on the tails from the element and it should read say 50 to 250
ohms. If so it is ok, if very high say over 500 ohms report your
reading back, if no reading then it is faulty.


That's what I needed to know, ta.

I assume it is a thermostat in the control unit rather than one under
the tiles that is connected to the control unit.

Yes. Aren't new ones expensive?! Around £50.

The best way to test
it is to connect the tails of the element to the feed to the control
unit thereby bypassing the unit.


I'll try that if it looks like the element's ok.

If the floor heats up the unit is faulty. Unless that is the
instructions for the unit are just too difficult to understand which
they can be if they are not written clearly.

If you are not 100% confident with electrics do not even start this
investigation get some one who is!

That'll be the next step when I discover that it *should* be working but
still isn't ('letric gremlins at work)

Thanks again,
