Candy no power help please

[mrCatfish]

Hi,

I have a Candy R 43/3 X UK (which plugs directly into a normal 220v socket). A little while ago the oven bell would continually sound, so we had to switch the power off at the mains between use. The other day, upon switching the power back on at the mains, a loud bang was heard in the oven and it would no longer power up.

I have checked the fuse, checked the wiring block where the mains supply enters the oven, and neither are burnt out or damaged. I also checked for continuity with an ohmeter and this all seems fine. There are no obviously burnt or scorched parts. I checked both elements for continuity and they seem fine.

I now suspect the infinite switch, but can’t find any info on how to test it. The switch, (labeled TR/86) has three leads labeled P1, 1, and 2, but only the first two have connections from the oven. There is also a blue wire leading into the bottom of the switch, but this is molded right into it, (this wire looks suspicious as it was chafed and very near to the appliance chassis… I wonder if this shorted out).

How do I test this switch?

If this does turn out to be the problem, can I just disconnect the bell and live without a timer, or should I replace the entire timer too?

Thanks in advance!!

Hmm… okay, anyone know of any generic instructions for testing infinite switches? The only ones I can find are for switches with a lot more connections.

What is an infinite switch?

Thank you – it would have been much simpler to have called it a thermostat. It’s a make and break switch, controlled by gas expansion in a capillary tube, operating a diaphragm mechanism and in turn, the switch.

At Off, the switch should be open. At the ambient, the switch should close and allow power to pass through. Select a higher temperature and the elements will raise the temperature. The expansion of the gas should cut off the switch at approximately the correct temperature.

Thanks for your help.

I assume that the actual switch that is attached to the front of the oven doesn’t do all of what you described though as I guess an actual thermostat inside the oven talks back to it to tell it when to cut the power. I wonder if this is the blue wire coming back into the switch. Not sure still how to test this switch, I guess it’s time to call someone in.
