Short answer

A Sub-Zero that creeps a little warmer each week is losing ground to something gradual: dust thickening on the condenser, a door seal that no longer grips, or refrigerant seeping out of a system that should never need more. Sub-Zero Repair Edmonds sorts out which one for the $89 service call, on (206) 210-3547.

A slow slide has slow causes

A part that stops outright, a fan motor for instance, tends to announce itself: the section goes warm and stays warm. A reading that edges up over weeks has a different shape, and it shortens the list. The likely culprits, cheapest first:

  • The condenser (the coil behind the grille that throws out the heat taken from the food). Dust settles on it a layer at a time, and each layer makes the compressor (the pump that drives the refrigerant round) run longer for less cold.
  • The door gasket. A seal that has flattened or split lets kitchen air in all day.
  • Frost the defrost has stopped clearing, gathering on the cold coil behind the back panel. Only the panel coming off confirms it.
  • A slow refrigerant leak. Refrigerant travels round a closed loop and back to the compressor; nothing uses it up. When the charge runs short, some has escaped through a pinhole or a tired joint. In homes near the water, down in the Bowl for instance, salt carried on the air is one known cause of pitting in copper and aluminium.

Keep a log, then let us measure

Sub-Zero’s method is a thermometer standing in water, the glass placed at the centre of the fridge and left 12 hours; the display shows the setting, not the real temperature. Write the reading down morning and evening for several days, with the weather beside it.

On the visit the condenser and its fan are looked at first, then the gaskets and the coil. Gauges come last: low pressure on both sides of the system points to a leak, and the hole has to be found before any refrigerant goes back in.

What it may cost

$89 to find out — the visit and the diagnosis, taken off the repair if you go ahead.

  • Compressor or sealed-system repair Shows as a compressor that clicks and will not start, or refrigerant slowly lost $1,300–$3,270
  • Door gasket or seal replacement Shows as one section creeping warm, beads of water or frost along a door edge $270–$620

Ranges, not starting prices. The technician names one figure inside the band before any panel comes off, and Sub-Zero Repair Edmonds holds to it.

Wait or call today?

Can wait until morning

  • A thermometer in the fridge still reads 40°F or lower and the freezer is hard: start a daily log and book a visit.
  • The change is slow and steady, with no smell, no water on the floor and no new noise.

Call today if

  • The fridge has crept past 40°F. By the FDA's rule, perishables kept above that for four hours or more are thrown out.
  • The warming has picked up speed over the last few days, or the freezer has begun to soften as well.
  • There is an oily smear on tubing you can see through the grille.

Anything in the second card is a reason to phone Sub-Zero Repair Edmonds on (206) 210-3547 today rather than tomorrow.

Questions people ask next

How can I tell a slow leak from a spell of warm weather?

Warm weather makes any refrigerator run longer, and Sub-Zero says temperatures normally fluctuate a little with door openings, humidity and room temperature. What weather does not do is push the reading higher week after week while the kitchen stays the same. Keep one thermometer in one spot for several days; if the numbers keep rising on mild days too, have it looked at.

Is a slow leak always the costly repair?

It is always sealed-system work, but the size of the job varies. Sub-Zero's service manuals allow a leak at a soldered joint to be repaired where it is, while a hole elsewhere can mean replacing the part that carries it. Either way the leak is located first, and Sub-Zero Repair Edmonds prices the work once it is: (206) 210-3547.

Still warm? Ring before the food goes.

Say which side is warm and what the compressor sounds like — that is enough to start. Phone it through, or choose a slot on the booking page. $89 to find out, and the $89 comes off the repair.
