You Didn't say which parts you have replaced so i have nothing to go on.

But we will begin from the start. F3 MAG CURR means you have a problem with the high voltage system in your oven, the microwave circuit.

The next part is extremely dangerous, if you have no background in electric STAY OUT. CALL A PRO you will be working with 5000 volts.

With that said you will need a clamp on ampmeter to measure the current to narrow down the problem.


Discharging can be done by unplugging the oven and then short across the red wire on each capacitor to the chassis with an insulated screwdriver.

1. Remove the top and right side covers.

2. Enter the test mode. (From the OVEN OFF mode, simultaneously press

BACK and ENTER keys, enter the code 9-4-2-8 and press ENTER).

3. Place amp meter on the brown "ct" wire for amp reading. Wire is coming from the primary side of the

HV transformers and looping through the black plastic current transformer on the main control board and back to the HV transformers.

4. Press and hold the MGTRON soft key on the keypad to energize the magnetrons.

5. Observe the amperage on the meter. Typical readings are:

NORTH AMERICA: 12-14 amps at 240VAC/13-16 amps at 208VAC.
If you are getting 12-16 amps then change the I/O board.

If you are only getting 7 or 8 amps then only one side of the of the HV system is not working correctly. You will need to figure out which side is bad by un-plugging the power wires going to one of the HV transformers. Then test again and if you get no amps you have found the bad side. Replace the HV transformer, cap and diode.

If you are not getting any amps then check the F3 fuse it will most likely be blown. Replace and start over

Good Luck If you have anymore questions just ask.

That typically means the microwave circuit is not powering on so the oven turns itself off. Most of the time when that happens you will get an error code flashing on the bottom of the screen. If F3 MAG CURR. Look at my previous answers on fixing that

IF YOU KNOW HOW TO USE CLAMP AMMETER THEN ONLY YOU CAN USE MY METHOD TO TROUBLESHOOT IT.
MAKE SURE OVEN HAS 5000V IN THE CAPACITOR.DISCHARGE THEM FIRST .
AND IF YOU DON'T KNOW THEN STOP HERE
STEPS
1. open right side pannel
2. press back key to turn off oven
3. press back and enter key simultaneously.
4. enter 9428 then press enter.You are directed to testmode.
5.put clamp ammeter on the primary wire(orange in color).The one which come from top and looping the IO board.
6.Under Displaty screen you see Word Magnetron.Press and hold the soft key to energize the magnetron.
7.Check the amperage.It should be under 14-16 Amps.
8.If its half of the value or nothing comes then.
9 half value means(one magnetron is working
10. No value means F3 fuse blown and check the cause why it blown(physically look at the transformers and the capacitors and the diodes that they didn't burnt or change their shape.
IF YES THEN REPLACE IT.

Hi, F3 mag curr. what is means and how do I fix it?


Hi,
F3 is an complex code.

Easy fix is look at the transformers and the capacitors and the diodes.If it seems that any component has changed its appearence then fix it and replace the F3 fuse(3rd one from the front).

If the magnetron is bad ,then to check that you must know how to use clamp ammeter.
let me know if you know how to use clamp meter .
I will give you the solution .

NOTE oven has 5000V in it.
make sure you dischared the capacitors.
Thanks

F3 Mag Curr. on Turbochef Tornado


Hello. Interesting coincidence, but that error code is for the magnetron/microwave part of the toaster. You will need to have it serviced by someone familiar with the unit, it could be easy and reasonable, if just a fuse blew, but not likely. If the fuse blew, it is 20amps, so something took it out. Call turbo chef, they will get you to the closest servicer, may be able to help you on the phone.
