The short answer
On a Conservator top-freezer refrigerator this complaint is usually a defrost cycle that is not running rather than the failure owners fear, and where it is not, a control set for the refrigerator and not for ice takes most of the rest. Conservator sells the plain top-freezer that goes into rentals and second kitchens: no dispenser, no display, one fan and one defrost heater doing all the work. Work the list in the order it is given and you will either fix it or know what to tell the technician.
What you observe
- Ice that takes far longer than it used to — Lost capacity rather than a failure, and it usually has a cause you can see.
- Ice that forms and then softens again — Something is warming the compartment periodically - a door, or a defrost cycle.
- NEAR MISS - nothing in the cabinet is cold either — Then this is a cooling fault, not an ice one, and the cooling page for this cabinet is the one to read.
Causes, most likely first on this brand
- A defrost cycle that is not running — Top of the list here: when the evaporator glazes over, airflow into the compartment falls away, and the first thing to suffer is the job with the least margin - making ice.
- A control set for the refrigerator and not for ice — Second here: one dial serves the whole cabinet on this design, so a setting that keeps the fresh-food side pleasant is often a setting that will never freeze a tray of water.
- A door that is opened too often or left ajar — Third, and worth the two minutes: freezing water is the most demanding thing this cabinet is asked to do, and it is the first job to fail when warm air keeps arriving.
Check in this order, and why
- Look behind the rear panel for a wall of ice — On a frost-free cabinet this is the check that names the defrost system.
- Put the control to its coldest setting and wait a day — Free, and on a single-control cabinet it is the likeliest fix.
- Test the seal and count how often the door is opened — Warm air is what the compartment has least defence against.
What an owner can safely check
- Listen for the fan at the freezer with the door open — On a frost-free cabinet, no fan means no cold reaching the compartment.
About 5 min
- Set the control to its coldest position and give it a full day — One dial serves everything on most cabinets in this class, so this is the cheapest thing that can work.
About 10 min
- Test the door seal with a slip of paper at several points — Where it pulls out freely, warm air is arriving continuously.
Tools: a sheet of paperAbout 10 min
- STOP HERE if the next step means a meter or the rear panel — Behind that panel are the evaporator and live terminals, and that is where owner checks end.
Before you open anything
Safety
Unplug the refrigerator or switch off its breaker before removing the rear freezer panel or pulling the kickplate, because a capacitor can hold a charge after the power is off. A full-height cabinet is heavy and top-loaded - move it on both front corners rather than dragging it by the door.
When to call a technician
Call when the fan is turning, the evaporator is bare, the door seals and the freezer still cannot make ice at its normal rate. Call the same day if the freezer itself is no longer holding temperature, because at that point this has stopped being an ice problem and has become a food one.

What this page does not cover
This page covers full-height refrigerators as a class, not one family or model, and it does not cover plumbed ice makers in detail - fill valves, supply lines and harvest mechanisms belong on the family page for your unit, linked below where one exists. Not here: cycle times, capacity figures and part identifiers.
