TurboChef Error Codes and What They Mean

TurboChef Logo - TurboChef Error Codes

From fast food chains to cafeteria kitchens, TurboChef ovens are used throughout many establishments. They manufacturer a wide range of equipment designed to cook different foods fast. When your unit isn't up to par, it can halt your kitchen quickly.

Fortunately, certain models display a helpful error code to tell you what's wrong. But what exactly do these codes mean?

We've put together a list of common TurboChef error codes, featuring possible causes and solutions. That way you can get back to cooking everything from pizza to hot sandwiches in no time.

F1: Blower Running Status Bad

*Alternate displays include: F1-1/F1-2: Blower Running Status Bad, F1: Blower Failure

Possible causes and solutions:

  • Power is interrupted – Check that the wall circuit breaker is on. Reset it before powering the oven back on. If that's not the issue, turn off the oven and unplug its power cord. Plug it back in after two minutes, and switch on the isolator and main power supply. Once it's on, select "Menu" and set the temperature. 
  • Blower motor not running – This will need to be solved by a professional. Contact a service technician or TurboChef customer support.

Associated models: Bullet, Eco, i3, i5, Single-Batch, Double-Batch Rapid and High-h-Conveyor Cook Ovens

F2: Cook Temperature Low

*Alternate displays include: F2-1/F2-2: Cook Temperature Low, F2: Low Temp During Cook

Possible causes and solutions:

  • Power is interrupted – Like the F1 code, see if the wall circuit break is on. Make sure to reset the breaker before turning the oven back on.
  • Clogged air nozzles on cook cavity – Check if the air nozzles on the top of the top and bottom of the cook cavity are clogged. If so, clean them and the surrounding area.
  • Poor door alignment – Try opening and closing the oven door several times to make sure it's sealed shut. You might have to realign the door, replace it or fix the gasket or hinges.
  • Defective heater – Start by resetting the high-limit in the bottom left corner of the oven's rear wall. Contact a service technician or TurboChef customer support if the problem continues.
  • Oven not fully warming up – If your oven isn't heating up to the set temperature, repeat the warmup process and allow the oven to idle for about five minutes.
  • Blower motor not running – This will need to be solved by a professional. Contact a service technician or TurboChef customer support.
  • Dirty oven – A dirty oven can prevent it from warming up to the desired temperature by reducing its energy efficiency and heat circulation while also causing issues with the heating elements and sensors. Clean your TurboChef oven at least once a week to prevent grease buildup from interfering with its temperature.  
  • Overloaded belt – Another reason your oven might not be reaching its setpoint temperature could be because you overloaded the conveyor belt with food. Try removing a few products and see if that doesn’t fix the problem.
  • Low voltage – A low voltage supply means a call to an authorized service technician.

F3: Magnetron Current Low 

A defective microwave circuit is the root cause for a low magnetron current. The problem will need to be solved by a professional, so contact a service technician or TurboChef customer support for assistance.

Associated models: i3 and i5

F4: Door Monitor Defective

A faulty door monitor occurs when the oven door switches are out of order. Have this problem solved by a professional, so contact a service technician or TurboChef customer support for assistance.

Associated models: i3 and i5

F4: Emergency Stop

This code appears when the emergency stop key is pressed, acting as a counter that logs how many times the key is pressed. This will clear from the display when the oven is restarted

F5: Magnetron Over Temperature & F6: EC Temp

*Alternate displays include: F5: CC Over Temp, F6: Electrical Compartment Temperature High, F6:EC Over Temp

Possible causes and solutions:

  • Cool air blocked – Cool air could be blocked from entering the oven. This can be resolved by removing any items or debris obstructing cool flow into the side and rear oven panel.
  • Clogged rear cooling fan exhaust guards – If the rear cooling fan exhaust guards are blocked, remove any debris clogging the rear fans.
  • Faulty SSR – Unfortunately, you’ll need to call an authorized service technician to fix the SSR and remove the fault code.
  • Faulty blower motors or heaters – An over temperature error code could indicate the blower motors or heaters are not working as intended. Call an authorized service technician to help fix the problem.

F7: RTD Failure 

The RTD is responsible for sensing temperature in your TurboChef oven. As you can imagine, an RTD failure might cause inaccurate temperature readings, leading to your oven not heating properly or trigger an automatic shutdown. An open or disconnected RTD will display on the screen as 999.° When this happens, it’s best to leave it to the professionals and call an authorized service technician.

F8: High Limit Tripped 

A dirty oven can cause the high limit to trip. To remedy the issue, follow the daily and weekly cleaning procedures as described by the manufacturer.

F8: Heat Low

If the oven does not heat up to 14℉ within 30 seconds while the oven is warming up in Test Mode, you get this lovely guy on your screen.

F9: Belt Run Failure 

  • Overloaded belt – If there’s too much weight on the conveyor belt, the oven might come to a stop. To fix this, remove excess product from the belt, turn the pizza oven off and wait until it’s completely cooled before starting it up again.
  • Obstructed belt – Another reason your pizza oven’s conveyor belt may have stopped is if there’s something physically obstructing it. Turn off your pizza oven and wait for it to cook before examining the oven cavity for any food or other debris that may have created a jam.
  • Overheated conveyor drives – The conveyor belt might also come to a grinding, screeching halt if the conveyor drives overheat. Possible causes for this include dirty filter, the fans are not working or the ambient temperature exceeds 100℉.
  • Faulty components – If you have tried the above TurboChef troubleshooting techniques and still come up empty handed, it may be because an internal component has finally run its course. Call a trusted and authorized service technician to help remedy the issue.

F9: Cook Cavity Temperature High 

An F9 fault code means that the RTD (temperature sensor) detected a temperature exceeding 650℉ for more than 40 seconds, but less than two minutes. This fault won’t cause your pizza oven to stop cooking, but it will appear in the fault log. Possible reasons for this error code include: 

  • Dirty oven – An oven which daily and weekly cleanings have been neglected might be at risk for excessive grease buildup, which can cause temperatures to soar above the preprogrammed upper limits as grease is burned off.
  • Greasy product – If you’re following a strict cleaning regimen and you’re still finding the RF error code in your fault logs, this may mean your product is too greasy or you’re cooking it in too large of batches. Consider reducing the batch size per cook cycle.

F10: Communication Failure 

If you see the F10 error code populate the screen, this means the UI control board is not communicating with the I/O control board. In this case, you’ll need an authorized service technician to get you back up and running. 

Associated models: Bullet

F12: Firmware Reboot 

If you see the F12 error code, this means the UI control board went offline for four seconds and the system needed to reboot. 

  • Outdated Firmware – In the info screen, you should be able to tell if your oven has the latest firmware version. If not, you’ll have to call TurboChef technical support to get the latest version. Once acquired, insert the USB when the oven is off, touch “update firmware” and then “ok.” Wait until the display reads “installation complete” before removing the USB.
  • Faulty USB port or cable – The oven should automatically detect the USB drive. If it doesn’t, this could indicate a problem with the USB port or cable. Call an authorized service technician for repair.
  • Dirty or clogged air filter – It could be that the rear air filter is clogged or dirty. Clean or replace the air filter to see if this doesn’t solve the problem.
  • Faulty power supply – If cleaning or replacing the air filters didn’t clear the error code, this might mean the power supply is faulty and may need to be replaced. Contact an authorized service technician for help.
