Common TurboChef Tornado Fault Codes and Issues

One of the biggest benefits of a Tornado oven is that it’s designed to consistently monitor and log errors. If you ever notice any issues with your unit, simultaneously press “4” and “6” while the oven is off to view the fault log to view the diagnosis. Below are common fault codes you will see.

Click the Codes Below to Read More:

  • F1: Blower Running Status Bad
  • F2: Cook Temperature Low
  • F3: Magnetron Current Low
  • F4: Door Monitor Defective
  • F8: Heat Low
  • Additional Fault Codes

F1: Blower Running Status Bad

This will display when the oven’s motor or motor controller isn’t running, and the cook cycle will terminate immediately. Unplug the oven before checking the motor. There could be an obstruction preventing it from spinning freely. If not, you could have a fault motor or motor controller that needs to be repaired or replaced by an authorized technician.

F2: Cook Temperature Low

If the cooking temperature is about 84°F below the set temperature during the cook cycle, this code will appear. See if the high-limit thermostat is tripped by resetting the oven and warming it back up.

If it’s not tripped, place a small amount of water in a microwavable container while the oven is in “Test Mode.” Start the microwave by pressing the “MGTRON” key, and hold it down to watch the CC and IR temperatures. If either fluctuates substantially, there may be some wiring issues that would need to be resolved by an authorized technician.

F3: Magnetron Current Low

A magnetron is what actually creates microwaves in your unit. When the current is low during the cook cycle, there could be issues with the machine’s K2 mechanical relay or wiring. Consult an authorized technician for further assistance.

F4: Door Monitor Defective

This error code displays when the monitor interlock switch opens before the primary or secondary interlock switches. Check if there are any obstructions keeping the door open, or see if the monitor safety switch needs to be readjusted.

If neither are the issue, check out the latch assembly. When the door closes, see if the actuator is clearing the slot on the flange and that it rotates smoothly when striking the toggle latch. If that’s not occurring, look for the following:

  • Actuator not clearing the slot – If the actuator doesn’t clear the slot, have an authorized technician to adjust or bend it. The technician might need to replace the actuator if there is significant damaged.
  • Toggle won’t rotate smoothly – Try to clean and lubricate the assembly and rotating parts, especially the torsion spring. If any parts are worn out, make sure to have them replaced by an authorized technician.

F8: Heat Low

If the temperature in the cook cavity doesn’t rise to at least 14°F within 30 minutes after “Warm Up” or “Self Test” modes, this fault code will trigger. Check the high-limit thermostat. If it’s tripped, reset the oven and allow to warm up again. If not, consult an an authorized technician for assistance.

The blower motor also could be a problem. If it’s not moving air, see if the motor in the assembly is stalled. Correct this issue by unplugging the oven and remove the obstruction or replace the motor.

Additional Fault Codes

The fault codes below are a bit more complex and will require help from an authorized technician:

  • F5: Magnetron Over Temperature
  • F6: EC (Electric Compartment) Temperature High
  • F7: Thermocouple Open
