The short answer
The Comfort Time DSC refrigerator that will not cool while clearly running is telling you the refrigeration side is alive and something between it and the food is not. Cold is being made and lost here — through a dirty condenser, a stopped fan, or a door that rests instead of sealing. The models this page covers are second refrigerators in most homes, asked to hold temperature in rooms a kitchen unit never sees.
What the owner sees and hears
- The compressor runs but nothing gets cold — You can feel and hear the machine working, and the shelves never chill anyway.
- Heat coming off the back panel — This platform often straps the condenser to the back skin, so a hot rear panel is rejected heat with nowhere to go.
- Ice building across the vents — Light frost is normal on a static plate; an ice wall on a vented panel is not.
- The complaint appears in hot spells — These cabinets often stand in garages, and the margin they hold does not stretch.
- NEAR MISS — the cabinet is cold and only ice production stopped — Ice failures on a cold cabinet trace to water, not to refrigeration.
Causes, most likely first on the DSC line
- Failed defrost heater or terminator — The defrost path has three parts that can each stop the cycle, which makes it a leading cause on any cabinet that has one.
- A worn circulation fan motor — This one only counts if you have a fan, and the vent check earlier on this page is how you find out.
- Condenser coil choked with dust — It ranks at or near the top on this family because the coil sits in a tight bay where household dust settles and nothing sweeps it off.
What to check first, second, third
- Inspect the back panel for frost — Only relevant on the frost-free branch, and conclusive when it is: a sheet of ice there is the diagnosis.
- Hold the door switch and feel for a draught — On a fan-cooled model this halves the list in seconds, which is why it comes before any panel is removed.
- Pull the unit out and inspect the coil — First by design: the rest of this list assumes that heat is actually leaving the cabinet.
Safety first, and it is not optional
Safety
Move perishables to a cooler before you start — a refrigerator holds food safely at 40 °F (4 °C) or below, and a warm cabinet has already stopped doing that. The condenser and the tubing around it run hot while the unit works, so let them cool before cleaning anything. Never open the refrigerant tubing — that line is where the owner side of this repair ends.

When this stops being a DIY job
The line is the sealed system: what is outside it you can do, and everything inside it is not. If the fault is in the defrost circuit, a technician can confirm which of its parts failed in one visit.
