20 Most Recent TurboChef TORNADO Electric Oven - Page 2 Questions & Answers

There are 2 hv transformers. If you take the right side cover off, they are towards the top of the unit. I think you need to take the top cover off, as well, to replace them. If you google turbochef tornado, there are very detailed repair manuals available for free. They shouldn't be hard to replace yourself. You might need to replace the capacitor (s) too. If it won't stand up on its own without falling over then good chance that is shot too. Remember to take a picture before you take everything apart, so you know how it goes back together. Remember to unplug!!! :). These are pretty easy to work on yourself. A service call will cost you at least $500 to replace a fairly cheap part. I learned the hard way. Below is a pic of a transformer, capacitor and mag. They were all bad. Eventually a bad mag will ruin your transformer and capacitor.

take top cover off. It's about in the center. install a new one. pretty simple part to change. of course always unplug oven first.

What jim said is right. plus clean the front vent. take off bottom front panel and clean all the little round holes. also if its dirty inside everything runs hotter(which makes the EC get warm faster) and dirt gets on the little wire(it's about 4" long coming from the main 40 pin connector0 that monitors the EC temp(clean it). sometimes the fan starts to get weak and doesn't cool properly. also, unplug oven, take side panel off and clean it as well. there are vents on it that get clogged. while it's unplugged clean the inside. I use a paint brush and shop van. just be careful not to hit wires or knock wires off. this will all help a bit but that fan will still run a lot anyway.

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. OKAY LET ME KNOW IF YOU CAN REACH UPTO HERE . AND REPLY ME THNAKS PLEASE RATE MY WORK

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

Faulty door switch

Yes any thing that is not greasy as it will block the catalytic converter

Martin food equipment Ireland, they will post on prepared order

Sounds like it needs new main pub.

If it's coming from inside the oven ,clean underneath the cooking stone, if it's coming from the side panel it's probably the mag transformer.

I believe f6 ec temp is your code. That means the electrical compartment is getting to hot. Most common is the fan on the back of the oven is weak and not moving the air fast enough. Also the electrical compartment could be loaded with dust.

Reset the high limit thermostat switch on back side of oven. If that doesn't helped then either your IR element is out or cc heater is bad

Usually these happen when IO board is about to go. I have experience this . Clean the board and try to plug in wire connector back to the board. If it eke minarets or creates any new error code then you definitely need io board

Bad SSR relay. Thermostat is for safety so it tripped first time, however since it's mechanical thermostat( not so accurate ) it didn't tripped on time for next time when it overheat

Security torex bit t15 something

Bad SSR relay, te relay is shorted it keeps feeding the power to the it element . Or else bad IO board. You should know how to diagnose it though. Otherwise don't touch it

All the switched are usually on back side of the oven, it must be small red color switch

You might have tripped thermostat. Reset it and see if the temperature rise, if it doesn't then either the high limit thermostat is bad or bad SSR relay. I can help you more if you know about electrical stuff.

switches or door out of adjustment, f2 most likely a wire burnt off on top cc element

hi,
you didn't ask any question.
please ask
I will be happy to assist you
