Pull the unit out away from the wall, unplug, your unit and remove the lower cover down the bottom of the unit by unscrewing the 1/4"screws.You would then plug your unit back into the wall outlet. After doing this you would then visually check that the compressor fan is spining properly and if you use the palm of your hand against the side of the compressor if the compressor were working you would feel a vibration. If you do not feel a vibration or are able to tell that the compressor is not running you would then look at the small black box on the side of the compressor. You would once again unplug your machine and remove the small black box which will give you access to the start relay and overload. You would then unplug the start relay and overload and observe the relay for any black electrical burns or if you shake the relay and hear a rattling noise on the inside of the relay, this is most often a sure sign that the relay is at fault and needs to be replaced. If the relay is good then you would then check your power cord going to the unit and the wires going to the start relay. Lastly you would check the main power board which is usually located behind a panel on the back of the machine. If you have any further questions message me back. I await your reply Thank you, Rick
If BVSV is to do with the brake vacuum servo unit, then yes, it could easily be the cause of the high idle speed. This will cause the engine to run lean too, and admit dust and particles into your engine.
HI, The power surge has, essentially, destroyed your main control boards circuitry. This will happen during a power surge. Most oven control board are not protected from this type of potential damage. To confirm, simply unplug your unit for 5 minutes. Once the five minute reset has passed, simply re- introduce power to the unit, and observe. If you experience the same issues after the five minutes reset, this will confirm the damage to the control board.
It must be replaced if the damage persist after the reset.
HI. This will occur when a surge has entered the unit, due to the power outage. Normally, there will be a power surge when the power is re-introduced to the home circuits after a brief outage. This will damage most unprotected electronics in this situation. The most vulnerable area in the unit will be the main control board. I would advise to try a hard rest. You can initiate this by simply shutting down the appropriate circuit breaker, or unplugging the unit for 5 minutes. Once the 5 minutes have passed, kindly re- introduce power to the unit, and try to run a baking cycle. If the word stop, or PF illuminates on the display, this will confirm that the surge has damaged the board. It must be replaced, in this case.
HI. if this unit isn't powering up, it could be an issue with the power supply board. To confirm this diagnosis, i would unplug this unit from the surge protector for about 5 minutes. once the 5 minutes are up, plug the unit into a regular wall socket. If the unit doesn't power back up after being unplugged for 5 minutes, this will confirm the power supply failure. you can order another power supply board form the manufacture or, you can simply send the unit back to Sony for this repair as well. If this unit is not plugged into a surge protector, it may have received a surge of some sort.
Check your manual for instructions to see if CPU temperature monitoring is done in that system.
You may be able to view that actual operating temp. of your processor.
If that system is so equipt, then it is very possible that the fan speed is regulated by temperature and it will vary according to ambient and internal temperature to conserve a tiny bit of power.
If nothing else, you can block airflow into or out of the system box to see if the fan speed increases after a few minutes.
Blocking the exhaust in the back of the unit will probably be enough.
NOTE: DON"T walk away if you decide to experiment - you may fry some chips and those don't taste good at all!
