Work out what is wrong before you pay anyone
Written from Denver service calls. If one of these fixes it without us, that is a good outcome — you will call when it is something that needs a meter.
- 01 Why a Sub-Zero Trips the Breaker in an 1890s Baker House: Dedicated Circuits in Denver's Oldest Housing A Sub-Zero tripping a breaker in Baker or Bonnie Brae is usually a shared circuit rather than a dying compressor: the trip comes at compressor start-up, so the first tests are circuit identification and a voltage reading taken while the unit starts.
- 02 Hollow cubes, cloudy ice and an empty bin: Denver water and a Sub-Zero ice maker Most Sub-Zero ice makers in Denver slow down because of water, not because the module has failed. How clear ice is actually made, what scale and low pressure each look like, and the checks that tell you which one you have before a part gets ordered.
- 03 Fresh food side warm, freezer still cold: what a Sub-Zero is telling you A warm fresh-food section with a cold freezer is the most misread Sub-Zero fault there is. What the two-circuit design means, the four things it usually turns out to be, and what you can check in a Denver kitchen before paying anyone.
Some faults do need a meter
Describe the symptom on the phone and you will usually hear what it probably is before anyone drives out. A $89 service call covers the visit and the full diagnosis in Denver, and comes off the repair once you approve it.
