Anets Fryer Error Code OFF: Computer Will Not Turn On
OFF (cannot be turned on) on an Anets AEP14 means the fryer's computer is not coming up, so the vat will not heat. Make sure the oil is cool, switch the building breaker off, wait a moment and switch it on, then try the power key once more. If OFF remains, leave the fryer off and call us.
Medium: the fryer cannot heat until the computer starts, but nothing is unsafe.
What does Anets error code OFF mean?
On the AEP computer, OFF is the screen of a control that is waiting to be switched on. When pressing the power key does nothing and the word stays, the computer has not started. The owner's manual points to the building breaker first, because a power dip or brownout can leave the computer stuck in a state it cannot leave, and cycling the breaker restarts it cleanly. If that brings the control back, nothing more may be needed. If it does not, the manual's list continues with the supply wiring, the control power circuit inside the fryer, the computer itself and the wiring plug behind the control. This page covers the display reading OFF (cannot be turned on), where the key press has no effect. The fryer stays cold and the vat will not heat until the control starts. Because the remaining causes sit behind panels or involve line voltage, the safe operator step stops at the breaker and the power key.
Affected models and control systems
This applies to the Anets AEP14 with the AEP computer control. Other Anets controls use different messages.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- The display reads OFF and the power key does not turn it on
- The fryer stays cold and the oil does not heat
- The screen came up blank after a storm or power dip
- Nothing responds on the control
Possible causes
Listed in Anets's documentation
- Breaker tripped or supply wiring to the fryer failing
- Control power circuit inside the fryer has failed
- The computer itself has failed
- Wiring plug behind the control loose or damaged
Other likely causes — what usually sits behind error code OFF on this control. A technician confirms which one it is before any part is replaced.
- A breaker that tripped quietly and was reset but left the control without a clean restart
- A power plug behind the control that has vibrated partly out
- A control power supply that browned out during a dip and has not recovered
Safe checks before calling for service
- Make sure the oil is cool and nothing is cooking.
- Switch the building breaker for the fryer off, wait a moment, then switch it on again.
- Try the power key once more.
- Do not open panels or touch wiring.
- If OFF is still on the screen, leave the fryer off and call us.
How a technician diagnoses error code OFF
- Confirm the supply voltage at the fryer after cycling the breaker.
- Check the control power circuit with a meter.
- Inspect the wiring plug behind the control for looseness or heat marks.
- Test the computer with known good supply.
- Check the key panel for a stuck power key.
- Replace the computer only after the supply tests are good.
- Checking control power means meter readings on live electrical equipment behind panels.
- Repeatedly cycling the breaker can hide a failing supply.
- Replacing the computer should only follow supply tests by a technician.

Why does the screen just say OFF?
The computer is not starting. The power key has no effect until it comes up.
Will cycling the breaker fix it?
Often, if a power dip left the computer stuck. If not, the computer or its supply needs testing.
