Question about TurboChef TORNADO Electric Oven

Turbochef Tornado EC cooling fan ALWAYS runs at full speed

The EC cooling fan is ALWAYS running at full speed. Turbochef says it should run when EC gets over 120 degrees, but I don't think it is that hot. Not comfortable opening side panel with oven running and 4000 volts there.

    Thanks Jim and Lou. The unit is clean so I know I have good air flow, and I replaced the EC cooling fan in hopes it would be quieter. It just runs full speed 100% of the time. Where EXACTLY is the temp monitored? Is the fan either on or off, without having slower speeds? It is definitely pulling a lot of air through the EC and I don't think its over 120. Wondering if temp sensor is bad and/or easily replaceable? Service call will cost hundreds. Thanks.

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.

SOURCE: turbo chef oven F6 ec code

Hello. There is a temperature sensor built into the control board, and the temp in that area, is getting too hot. On the back of the unit, right top, there is a cooling fan that comes on at a certain temperature, if the intake is clogged, you will get this error, clean the intake. Inside the unit may be so dirty, it may require cleaning as well. The fan itself could be bad, and does not run, then it will need replacement.
Hope that helps, and thank you.

SOURCE: Problems with TurboChef TORNADO Electric Oven f8

F8 means Heat rise low the oven failed to warm up in a predetermined time period. First check for problems with the blower and then check the high limit thermostat to see if its tripped. If these are okay call a repair tech because you will need to check the relays for problems

SOURCE: I have NGC tornado Turbochef, it is toasting too

the subway ovens are supposed to be around 1000 dont change any of the settings if you think you are having programming issues speak to your field rep and ask them to reprogram your oven. they have a smart card for doing this. it will give you all the latest buttons including hashbrowns and breakfast stuff.

most common problem with toasting to dark is that you are using the wrong buttons

try cooking the next sandwich on the 1meat hotwell setting and select the sandwich size. you will notice the sandwich cooks much lighter.

if you cook using the combo subs button this could be your problem. most of the time re-training is just needed

What means code F6


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.

Tornado ngc oven has an F6 code. IR heats up to 1160 degrees but never says ready


unplug oven. Discharge Caps- if you don't know how to do this stop here and call a professional.

push the small red reset switch rear lower corner of oven. IR is a little higher than i like to see.

Test electrical compartment thermal-couple. located under top cover about 2 inches from the rear in center.

Test Electrical compartment cooling fan.



EC Thermocouple (P/N 700-1199)
Type K Thermocouple. Thermocouple measures the
temperature of the electrical compartment. If the
temperature within the electrical compartment is
above 158?F (70?C), the control displays F6: EC
TEMP. The control board checks the EC temperature

My oven is showing F6 EC TEMP on the screen how do I fix it? Please let me know.


F6: EC (Electrical Compartment) Temperature High

Fault is displayed when the EC thermocouple

exceeds 158?F (70?C). It is monitored once per
minute.

The electrical compartment is overheating. Remove the panel on the right side and clean out all the dust. Check the fan at the back and see if its blowing alot of air. Sometimes this fan can get so clogged up with dirt, it slows down the air flow.

My turbochef tornado gives an error messag of


this is simple to fix but usually costly sorry to say.

F1 blower means the motor is not running when commanded.

first check the motor and verify if it spins freely - if the motor does not spin freeely remove the obstruction or replace the blower part# NGC-1025
just to clarify its the big blower behind the cook chamber not the little fan in the electrical compartment.
