Nothing is getting cold
Compressor Never Cycles Off in a Heat Wave
It has not stopped running for days, and the question is whether that is the weather.

| What you see | Likely cause | Safe check | When to call |
|---|---|---|---|
| Running non-stop in a hot spell, food still properly cold | Heat load: a warm kitchen means longer runs to hold the same ground | Judge the food, not the noise; wait for the evening to cool | Only if the food starts to slip |
| Running non-stop and slowly losing the food as well | The condenser matted with dust, or the fan that cools it has stopped | Feel for moving air at its machine grille: top on a column, toe kick below | This week. It cannot keep this up |
| Never rests, and one door feels cool along its edge | A seal letting warm kitchen air track in as fast as cold is made | Close the door on a sheet of paper and see whether it pulls out easily | This week, in the hot months especially |
| Never rests, and the freezer wall is white with frost | A defrost fault, so the machine is cooling through a layer of its own ice | Look at the freezer rear wall once the drawer is clear | This week, before the fan is caught |
The table above sorts a cabinet that never rests by what else is true about it. Row one is the Tarzana and Burbank answer for most of the summer and needs no repair; rows two to four do. Call Viking Repair Service Los Angeles at (213) 799-7879 if the food is slipping too.
When long runs are just the weather
Row one is not a repair. Whatever heat the kitchen gains has to be pushed back out, and a west-facing Tarzana kitchen in September gains plenty. A machine running on while the milk stays cold is winning, slowly. Judge it by the food rather than by the noise.
When it is the cabinet losing ground
Rows two to four are the same machine losing instead of winning. A matted condenser or a stopped fan traps heat, a tired seal keeps feeding warm air in, and a defrost fault makes it cool through its own ice. Left alone, all three end the same way: it runs until something gives up. The condenser fan work is the cheap one, quoted from the fan and defrost band.
Normal, not normal, and the line between them
-
Normal
Long runs from mid-morning to late evening in a hot spell.
Not normal
The same long runs in cool weather, with the windows open.
Time to call
This week. The season is no longer the explanation.
-
Normal
Running constantly while the food stays properly cold.
Not normal
Running constantly while the fridge drifts and the freezer softens.
Time to call
This week, and sooner if the freezer is giving way.
-
Normal
Warm air off the machine grille the whole time it runs.
Not normal
Still air at the grille while the cabinet sides heat up.
Time to call
This week. Nothing is carrying the heat away.
In a valley August the length of a run tells you less than what the food is doing. Call Viking Repair Service Los Angeles at (213) 799-7879 and describe the row you are on — that sentence is worth more than a guess at the part.
Safe checks before the visit
-
Vacuum the grille the machinery breathes through: the top one on a column, the toe kick on an undercounter. Take anything off the cabinet too. Burbank and Tarzana dust plus valley heat puts most of these calls on the list.
-
Hold the back of your hand at the grille while it runs. Moving warm air is the machine doing its job; still air with a hot cabinet is not.
-
Shut each door onto a sheet of paper and pull. One that slides out freely marks where warm air is getting in.
-
Stop there. Nothing further is an owner job on a built-in: the sealed circuit, the wiring behind the grille and anything that needs a panel off belong to the visit. Call Viking Repair Service Los Angeles at (213) 799-7879 and say which of the checks above changed anything.
Asked about this one
- Should a built-in ever run all day in a heat wave?
- It can, and in the valley it often does. A cabinet set into joinery has less room to lose heat, and the hotter the kitchen the longer the run. The test is what is inside: cold food and a long run is a warm week, while drifting food and a long run is a fault. Viking Repair Service Los Angeles sorts the two by measurement.
