Same refrigerator, two addresses, two different lifespans. The one in a new-build kitchen in Naperville goes fourteen years. The one wedged into a Lincoln Square two-flat goes nine. Nothing is wrong with either machine.
It comes down to breathing room
A refrigerator does not make cold. It moves heat from inside the box to the room, and it throws that heat off a condenser at the back or underneath. Give the condenser air and it works easily. Box it into a chimney-breast alcove built in 1912 for an icebox, with two inches at the back and a cabinet bridging the top, and it cannot get rid of what it is producing.
So the compressor runs longer. Then it runs constantly. A machine designed to be on maybe half the time is on ninety percent of the time, and the part carrying that load is the most expensive one in the cabinet.
What you actually see
- Warm milk on the door shelf while the back of the fridge is fine.
- Ice cream that never gets properly hard in August and is perfect in February.
- A hum that never stops, which the household has stopped hearing.
- An electricity bill nobody can explain.
- Condensation on the outside of the cabinet where it meets the cabinetry.
Things that help, in order of how much
Clean the condenser. Twice a year, not once. Unplug it, pull the grille, vacuum with a brush head. In a building with dogs or radiators this is the single most useful thing anybody does for a refrigerator.
Make a gap. An inch at the back and two above changes the airflow more than the numbers suggest. If a cabinet was built over the top, taking out the false bottom of that cabinet is a twenty-minute job for a carpenter and it buys years.
Move it away from the radiator. Old buildings put the radiator where the plumbing was, not where it makes sense. A refrigerator standing next to one is being asked to do two jobs.
When it is genuinely broken
A condenser fan that has seized, a start relay clicking every few minutes, a defrost heater that has given up. All three are ordinary repairs and all three are cheaper than the compressor you get if the airflow problem is left alone for another two summers.
If yours has been running non-stop since June, get it looked at while it is still a fan. Call 847-941-0334.
