Sub-Zero No Power Won't Turn On

An appliance with no power is either not being given any or not accepting it, and telling those apart takes one thirty-second test. Here is that test, and the one symptom that means stop rather than retry.

Common Causes

A tripped breaker or blown fuse

Worth ruling out first since it's the simplest and most common cause.

A failed power cord or internal wiring fault

Can develop over time, especially in units that have been moved or renovated around.

A failed control board

The unit may have power reaching it but a board failure prevents it from powering on normally.

What You Can Check Yourself

Check the breaker panel and reset any tripped breakers
Confirm the outlet itself has power using another device

Do not leave this one. Running the appliance in this state is what turns a single-component repair into a larger one, and on anything involving water or gas it is also the point where the cost stops being about the appliance. If you're seeing a code on the display alongside this issue, our Sub-Zero error code guide can help narrow down the cause before we arrive. Either way, our repair service covers same-day diagnosis and a flat-rate quote before any work begins.

Common Questions About No Power Won't Turn On

The breaker keeps tripping when I reset it.
Then stop resetting it. A breaker that trips repeatedly is doing its job — there is a fault drawing more current than the circuit allows, and forcing it back on is how a wiring fault becomes a fire. Leave it off and book the visit.
How do I tell if it is the appliance or the outlet?
Plug something else into the same outlet. If that works, the circuit is fine and the fault is in the machine. It is a thirty-second test that saves an entire category of misdiagnosis.
Is this worth repairing, or should I replace the unit?
On a built-in at this level, almost always repair. A column or a pro range is expensive enough to replace — and usually built into cabinetry that a different unit will not drop straight into — that even a significant repair wins on cost. The exception is a failed sealed system on a unit past fifteen years, and we will tell you plainly when that is what you have.
Will you have the part, or is this a two-visit job?
We carry the common failure parts for the brands we see most, so many of these are finished in one visit. Where a part is model-specific we order it against your serial number rather than guessing from the model line, which costs a day and avoids fitting something that nearly fits.
How quickly can you get to me?
Most calls across Denver get a same-day or next-day slot with a real arrival window rather than an all-day wait. Foothills and mountain addresses sometimes need an extra day, particularly in winter — see the complete list of cities we serve to check yours.
Is the repair guaranteed?
Every repair carries a written warranty of up to a year on the parts we fit and the labour we do. If the same fault returns inside that window we come back to it, and there is no second diagnostic fee for our own work.

Still having this issue?

Same-day diagnosis, genuine OEM-compatible parts, warranty of up to 1 year.
