Question about TurboChef TORNADO Electric Oven
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?
Transformer burn ? Replace it including capacitor.... Call the technician to do it... Let him check micro switch along also especially the primary....

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.

SOURCE: F3 FUSE BLOWING
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

the mag's only activate while in cook cycle, it will be hot as normal with toasted subs that are cold in the center.
AMP draw the Mag's and ohm the Mag thermal couples

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

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.
