You can test the board by crossing the 2 connectors to "close" the circuit for the mic (small black and blue wire) while vac is running and light should go to red every time you complete the circuit. WARNING: There will be exposed electrical points on board that could cause an electrical shock!!! or damage to board if not just crossing mic connections.

Getting an H97 error code on a Panasonic micro wave, I believe I am having an inverter problem


Troubleshooting of Inverter Circuit (U) and Magnetron
This oven is programmed with a self diagnostics failure code system which will help for troubleshooting, H97, H98 and H99 are the provided failure magnetron and inverter circuit problem areas. This section explains failure codes of H97, H98 and H99. H97, H98 and H99 appears in display window a short time after start key is pressed and there is no microwave oscillation.

zjlimited_1131.jpg

NOTE: DO NOT try to REPAIR this Inverter Power Supply (U) and also DO NOT RE-ADJUST PRESET VOLUME on the board. It is very dangerous to repair or adjust without sufficient test equipment because this circuit handles very high voltage and very large current. Off alignment or inverter board operation is dangerous. Operating a misaligned inverter circuit is dangerous due to the very high voltage and current that is produced by this board. Defective boards must be replaced with a new one.
- Check magnetron filament for open or short to casing before proceeding to determine a good magnetron.

Alternative way to troubleshoot oven with AC Ampere meter used. H97, H98 and H99 appears in display window a short time alter start key is pressed and no microwave oscillation with AC Ampere meter used for troubleshooting.

Dyson dc 15 brush roll not spinning. motor is good, upper switch is good.


Open the right side of the vacuum with a hex head screw driver. There are 4 screws. Inside you will find a circuit board.
1. Make sure the varistor (S20K150) is not blown, these models seem to have an issue with this. It is a flat blue "quarter" looking component near the top edge of the circuit board.
2. At the bottom of the circuit board are two white wires connected via push on connectors. Remove these from the circuit board by sliding them away from the circuit board. Power on the vacuum and engage the drive button. If the lower motor still does not engage check step 3.
3. A blue and yellow wire runs off the bottom end of the circuit board. These are the wires powering the lower motor. Check continuity with a multimeter and make sure they are not broken. I have seen where these wires will break as they run through the housing of the vacuum. If they are broken, replace them with any wire of the same gauge.

I have a 9068G and when I plug into the electrical outlet and press the "on" lever, I get nothing. The machine actually quit one time while I was vacuuming. Is there a fuse problem or a reset button? ...


There is no reset button or fuse, yo have a clog / reduced air flow, causing the motor to over heat and turn off. First change the bag, then remove the wands and carpet tool from the vacuum. See if the machine turns on. If not the main motor will need to be replaced. If it turns on and you have suction, check the wands or carpet tool for a clog.

DC15 Animal brush motor not working?


Just had the same problem. Switches and motor checked ok, then found the circuit board on the left hand side of cleaner. The fuse (on the board) looked ok, but when removed and checked for continuity I found it had blown. The problem I have now found is that the fuse cannot be ordered only the complete board. Hope it gets the brush roller going again.

My EL7020 so call Electrolux!


Check the electrical connections between the hose and the body of the machine, and also the wand connections all the way to the power head. Sometimes a faulty connection can send a false "off" signal back to the main body of the machine, and turn it off; but usually it will restart if that's the case. It sounds like you have a clog somewhere which is tripping your motor's thermal cutout, but you did say there are no clogs... so if you have full suction all the way down to the powerhead that's not the issue. You could have a faulty thermal switch, but I think the likely cause is, as usual; the sumo board.

Good luck. Sorry I didn't have a more concise answer for you.

Be sure to check the hose , wands and power brush for obstructions as well.
If there's a burning hair electrical odor then it might be toast.
i despise bagless vac's as they always wind up being more maintenance and expence then bagged vac's.

Good Luck and let me know what you find out.

Accidentally plugged into 220 volt outlet


The wiring diagram isn't showing a fuse, but there could be one on one of the circuit boards. Maybe the converter is bad. You will just have to take it apart and look it over. Maybe this pic. will help:
