What it is doing, and what that means

01Dead on the patio?

  1. If the GFCI outlet it plugs into has tripped, and one press of its reset button brings the unit backSafe to wait

    Sub-Zero requires the GFCI outdoors, so a trip is the protection doing its job. Reset it once, dry hands, and watch.

  2. If the GFCI trips again, will not reset, or trips whenever it rains, or everything is on and the unit stays darkCall (425) 321-3414

    Something is leaking current: the unit, its cord or the outlet. We test the unit; the outlet and circuit go to an electrician. Do not keep resetting it.

02Warm inside on a hot afternoon?

  1. If the patio is in full sun, the door has been busy, and it is cold again once evening comesSafe to wait

    A warm day makes the compressor run longer. Shade, fewer openings and a clear front help it catch up.

  2. If it is still warm after a cool night with the door shut, and nothing blocks the front at the footCall (425) 321-3414

    The weather is off the list. Outdoor dust and pollen are hard on fans and coils, which is why a fan motor is the line we show.

An outdoor kitchen is a different job

On a covered patio off Hollywood Hill or a deck above Cottage Lake, the DEU2450RO lives with rain, spring pollen, autumn leaves and grit. The seal collects debris, the front gathers more than kitchen dust, and the supply sits behind a GFCI meant to trip when water gets in.

One reset, then us

One trip after a storm is worth one reset. A second is not a nuisance to override. Touch nothing wet, and call.

If it is doing something else

Each page forks on what that unit is most often brought to us for, so the answer to a different symptom may sit next door: the Sub-Zero UC-24, the Sub-Zero UC-24C and the Sub-Zero DEU2450R. All of them price on the same cost page.

Asked about the DEU2450RO

Can any Sub-Zero undercounter refrigerator go outside?
No. Sub-Zero marks outdoor-approved models with an O, and among the current Designer undercounter refrigerators that is the DEU2450RO. Sub-Zero's ID-24RO refrigerator drawers are outdoor-approved too. Any indoor unit set out on a patio sits outside the outdoor warranty, which covers only products approved for outdoor use.
My outdoor unit keeps tripping its GFCI. Can I just replace the outlet?
Leave outlets to an electrician; we do not do electrical work. A GFCI that trips again and again is telling you current is escaping, from the unit, its cord or the circuit. Call Sub-Zero Repair Woodinville on (425) 321-3414 and we test the unit, so you know which side to fix.
