Lower/main oven bulb has blown and tripped circuit breaker. On replacing bulb and switching CB back on, main oven fan and light stay on, even when oven selector is off, albeit elements do not heat up. If I select the oven and turn on, it works fine, heats up etc. Only way to turn lower oven light and fan off is to set to auto, then reduce cooking time to zero, this works. But as soon as return to manual setting, the lower fan and light come back on. Any assistance appreciated. Thnaks Rod

When the main breaker trips it indicates current is escaping from the circuit to ground.
If it is a micro-circuit breaker that trips it indicates the circuit is consuming too much current - a short circuit.
Either way the wiring or the oven elements have a fault and need attention.
an open circuit indicates infinity which means no ohms and what the element should read is a closed circuit. open is bad and needs replacement as for the no fan check for loose wire or power issue also might want to check for a blown fuse
More than likely you have tripped the house circuit breaker or fuse. If you know where the house fuse box or circuit breaker panel is check to see if either one side of the two 240 fuses is blown or one of the two tied together circuit breakers is tripped. If it is a breaker then shut off both breakers completely and then snap them both on completely or they won't reset. It is rare that an oven has a fuse internally. There can be thermal fuses but they will trip when the temperature is out of range.
If your oven won't heat at all, the most likely problem is a blown fuse or a burnt out element. Assuming you're not attempting to repair an antique, your oven will have a clock. If it has also stopped working, it's safe to assume the oven is not getting electricity. Check your circuit breaker box and reset the breaker if necessary and see if this fixes the problem. If not, cut power to the oven at the breaker box before going any further. Note that your oven runs on 220 volts. There should be a double switch on the circuit breaker board controlling power to it. If not, there will be two single switches that need to be tripped to cut power to the oven. Even if you didn't find a blown circuit breaker, the problem could still be a blown fuse. Some older ovens have their own set of fuses located under the range top, in the back of the oven space, or behind the oven. Inspect the fuses and replace any that have blown with one of the same amperage. Your oven might also have a circuit breaker with a reset button on the control console or on top of the oven that needs to be reset. If you are still confounded, pull the oven away from the wall. If it is a range/oven combo, make sure it is plugged securely into the wall. If it is a stand-alone oven, inspect the wiring in the junction box to make sure everything is tightly connected and the wiring doesn't show any signs of damage.
It might be that the breaker is overloaded and it's no longer supporting the load of all the appliances together.If you do not want to change your breaker you can still use your oven by switching off other appliances that is running while you are using the oven
Sounds like oven element is faulty, disconnect it and try again, if it does not trip, then it is definately the element..
It is easy to replace.
Plz leave feedback.
I found the lower circuit breaker had been tripped. That didn't fix the problem but upon further inspection whoever had worked on the unit years ago had dropped a screwdriver that had lodged between the oven wall and the rear casing and shorted out the lower heating element. I removed the screwdriver and oven works fine now. I don't think that will solve the cmmclow problem but maybee the curcuit breaker is tripped.
