GE Refrigerator Error Code F133

F133 means the freezer door has been detected as open for 5 consecutive minutes without closing. The refrigerator monitors door status through a door switch, and when the open-door signal persists beyond 5 minutes, this code is triggered. It can indicate an actual open door, a blockage preventing closure, or a faulty door switch.

Resetting the refrigerator may temporarily clear the F133 display, but the code will return if the underlying issue is not resolved. If the door switch is faulty or the door is still not closing fully, the control board will detect the open-door condition again and reactivate the error. Address the root cause before relying on a reset.

If the issue is simply an obstructed door or ice buildup, there may be no parts cost at all. If a door switch replacement is needed, parts typically range from around 15 to 50 dollars depending on the specific model, with additional labor costs if a technician is hired. A door gasket replacement, if needed, generally falls in the range of 30 to 100 dollars for parts.

Start by checking whether the freezer door is actually closing fully and that nothing inside is blocking it. If the door closes properly, inspect the door switch for correct operation by testing whether it changes state as the door opens and closes. Also check the door gasket for damage and look for any ice buildup along the door frame. If the door switch is defective, replacing it should resolve the error.

A freezer door that remains open or is not detected as closed allows warm air to enter the compartment, which raises internal temperatures and can compromise food safety over time. The error is also a sign that the refrigerator is working harder to maintain temperature, which increases energy consumption. Addressing this code promptly helps protect both food and the appliance.
