What does OFF mean on my Unifrost fridge controller?

OFF usually means the controller is in standby, so refrigeration is not actively running even though the cabinet still has power.

What to do on-site:

Do not assume it is a power cut issue: OFF can be triggered by a button press sequence (sometimes accidental during cleaning).

Try to exit standby: use the controller’s power/standby function to turn cooling back on. If the keypad appears locked or unresponsive after a power cut, power can be present but inputs may be disabled until the correct key sequence is used.

Confirm cooling actually resumes: once OFF clears, check that the temperature starts moving toward setpoint and that alarms (like HI/LO) stop recurring.

If you cannot take it out of OFF or it immediately returns to OFF, note the exact display message and contact support with the model details.
