Falcon 211 GEO Oven tripping circuit breaker

[paclx]

I have a Falcon 211 GEO dual fuel range cooker and the left electric convection oven keeps tripping the circuit breaker. It heats up for about 3 – 4 minutes then……. If I reset the breaker then turn on the oven again, it trips almost immediately. I have just replaced the bottom element, but the same thing happens. As it seems to happen after the oven has reached a certain low temperature, could it be a faulty cut-off thermostat or oven thermostat?

Having to cook Christmas dinner with one oven is a real problem! Spoilt for too long with two!

Is it tripping the MCB or the RCD ? If it’s the MCB it would imply an overload which is unlikely to be a faulty element unless it’s gone S/C. Has this problem happened from new or just started happening?

Many thanks for your reply on Christmas Day!!!

It trips the main power to the entire floor. I assume it’s a RCD and it is very sensitive as it doesn’t trip the cooker MCB on the fuse board. The element is new, as I replaced it today. Still trips. It happened a year ago (at Christmas again) and I’ve only just got around to ordering and replacing the bottom element. According to the manual, there are two thermostats. One inside the oven to control temperature, and one somewhere else at the back to ensure temperature doesn’t overheat other components.

Forgot to add, the element was replaced by the service agents 4 years ago. I don’t use that oven often, as I prefer the fan oven on the right side.

Do you have a multimeter ? Can you measure a short between live and earth when the oven is switched on ? Is it a fan assisted oven ?

Re: Falcon 211 GEO Oven tripping circuit breaker

I have two ovens, one convection, the other fan assisted. It’s the convection oven that’s tripping the breaker. I’ll get my multimeter and check

Just tested it with the multimeter. As soon as I touched live and earth with the probes the breaker tripped (obviously the power to the cooker was OFF). Before I reset the breaker I tested and there is no measurement between live or neutral and earth. Oven control was ON

Re: Falcon 211 GEO Oven tripping circuit breaker

Your meter caused the RCD to trip as your meter will have sent a small test current between live and earth resulting in in I balance between live and neutral. It sounds like an insulation fault, is there any damage to insulation on wires for the oven or signs of arching around the oven thermostat ? If everything else works on the oven and the oven element has been replaced I would be first checking for signs of damage on oven wiring and looking for signs of electrical arching. Obviously make sure the power is off and isolated.

Thanks. It still seems odd that it only trips after a few minutes, rather than immediately the oven is turned on.

Hi

Check your elements

Paclx an insulation fault is where the insulation on cable or a component breaks down with heat or current. For the RCD to trip a leakage current if flowing between live and earth. If the rest of the appliance is working correctly then there are only a few components that can cause the problem, the normal cause being the element – did you say you had already replaced the element ?

Was the replacment element new ? It woul be unlikely to have a replacment element that is breaking down and this is why I said check the thermostat and wiring
