Sub-Zero Refrigerator Cycling On and Off

Repeated short starts and stops deserve a different description from normal intermittent operation. A timed account helps the technician understand what you are hearing.

What to check first

  • Record the approximate duration of each on and off period.
  • Note whether lights or the display also switch off.
  • Check whether the symptom began after a power interruption or recent service.

What the observations mean

Clicking and cycling can come from more than one component. If the whole appliance loses power, that is different from a motor starting and stopping while the display remains lit. Repeatedly unplugging or resetting the appliance can hide the sequence needed for diagnosis.

Before you request service

Capture a short recording from a safe position and include compartment temperatures. If there is a burning smell or visible electrical damage, stop using the appliance and arrange professional help.

Have the full model number, your city and ZIP code ready. Describe when the issue began and whether it is constant or intermittent. Avoid removing appliance panels, handling wiring or opening refrigerant lines; those checks belong to a qualified technician.

Call (224) 347-1756 or request service online. Appointment timing and repair options are confirmed after reviewing your request.
