Turbo chef tornado f3 smoke and bad smell

I bought a tornado used at an auction. It had been working until it let out a puff of black and gave an f3 error. It smelled really bad. Could this be a blown transformer? The f3fuse doesn't seem to be blown. I assume I would see a black mark on the fuse. I put an amp meter on the brown wire and it didn't show any amps. What should I try next to narrow down the problem?

James 938 hit the nail on the head. These ovens are very good and tend to be maintenance free, however, when it does have a problem, it is an unusual one. Good luck and let us know how it does.

If this is a C3 there is only one mag, F3 is the inline heater circuit fuse,
so it is a problem with the heater circuit, the older type heaters are an open coil type the ceramic mouting points can crack and break causing a short as the heater starts to heat, they are also susceptible to damage from oven cleaners. 208 volt units usually draw approximately 23amps when operating properly

SOURCE: F3 code I have replaced 2 high voltage

holy **** that was a very expencive fix huh. I hope you spent the 50 bucks and have a service manual. What about the diodes, have you tested or changed those. That looks like the last thing i would change and there only a few bucks so i would change them at this point anyway. Are you blowing a fuse at all.
You need to narrow the problem down, not just toss money into the toilet replacing good parts. If your reading 15.1 amps then you have no problem in the high voltage system. Unless the amps are ramping or erratic. Your I/O board is bad if its reading 15.1 and triggering an f-3 fault. You said you replaced it though. Contact who you purchased it from and see if they will help. Its a $420 board and $160 for each HV Transformer they should help. I would guess that your I/O board it bad. You also said you changed relays. Did you change the K2 relay.
Hope you can solve the problem quick. Hopefully this helps

SOURCE: f 3 mag error. had a bad magnetron and hv

F3 errors can indicate a mag problem. Did you replace both mags? It can also be a door switch. If your fuses are good, you need to inspect the 2 magnetrons. If you have a burned tip on one the waveguide and waveguide cover it will need to be replaced.

Gettinng message ''F3 mag''

Hello. "F3" is definitely the mag circuit, but not necessarily the magnetrons. Since you heard something "blow", I would be more inclined to look at the capacitors, and the rectifiers/diodes. It is possible that either of your HV transformers, or the preheat transformers has blown also, however, they would have smelled really bad and emitted a bit of smoke, which you did not mention, so I would go for the cap, diode first. Do you have access to a multimeter, and know how to use it? and just a word/warning. You are dealing with High Voltage components, that can/will kill you in an instant if not handled, or tested properly. If you had someone replace the Magnetron before, I would call them again, as they will most likely have what you need on the truck, or be able to get the correct part quickly. You could also call Turbo Chef, maybe they will sell you the parts you need, just remember there are 2 of each in there, so determine which one you need. There will probably be signs if it blew, of burnt plastic near the diode, which is under the cap. A capacitor will have a metal can, probably one will be out of shape near the top where the wires attach, you can look if you want, just unpug it please, and use a insulated screw driver to short the two termminals of the capacitor.

Hope all that helps, and thank you.

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.

or 1800 90turbo
Hope that helps, and thank you.
