Re: Electric oven tripping circuit breaker after turned on for 3-5 minutes
Today I reinstalled back the upper and lower elements, re-connect everything except the leaking upper element outer loop. Everything as there were, without additional RCCB.
Here's some unexpected, but interesting outcomes:
- Set mode to Lower Heating only, temperate at 50c, this was the last time when it tripped in about 3-5 minutes. Not expected to trip now since I have tested it previously, in full power for more than 10 minutes without tripping. But it trip! After 6 minutes.
- So I was thinking it could be caused by thermostat issue when it clicked off at set temperature.
- I reset power, and rerun Lower Heating mode but now at at Max (~230c). After running for ~20 minutes, all is still good at it has not reached the set temperature. I then turn the temperature knob down slowly. I think point I was expecting it to trip again when the thermostat clicking off, but it didn't!
- So I played around the temperature knob, turning it up and down to hear it clicking on and off. Nothing happened. I also set temperature at 150c and it clicked off and on without issue.
- I also set mode to Upper and Lower Heating mode, repeat various temperature settings, all OK.
- In all, after ~60 minutes of heating at various temperatures, including turning off and on a few times, all is good now.
So what could be the issue on 1st power up?
***I guess I will redo these tests again tomorrow, start with same Lower Heating mode, but set temperature higher at 150c to see if it would trip again at ~6 minutes point, or when it reaches the set temperature.
