The short answer
Every model in the FKATMP roster shares one capacity core and differs only in finish or trim, so the cabinet behind them is the same machine throughout, and its entries differ only in the trailing finish position. A refrigerator in this roster that runs without cooling is usually reporting an airflow restriction rather than a dead compressor. A refrigerator holds food safely at 40 °F (4 °C) or below, and a cabinet that has drifted above that while still running is telling you the cold is being made and not delivered.
What you observe on these models
- The cabinet is warm but clearly running — The compressor hum is there and the air inside is not cold.
- The freezer side is cold and the fresh-food side is not — Cold is made in one place and moved to the other.
- Frost building as a sheet on the rear interior wall — A layer rather than the usual light dusting.
- The compressor never cycles off — The cabinet is no longer reaching its set point, so the control never tells it to stop.
Causes, most likely first on the FKATMP line
- Vents blocked by stored food or an overfilled shelf — Ranked first on this roster: cold air has to reach the compartment through specific openings, and a shelf packed to the back wall closes them as effectively as a failed fan would.
- Frosted evaporator blocking the air path — It ranks second here because it explains the commonest version of this complaint, the one where the cabinet is cool rather than warm and the running never stops.
- Condenser choked or the cabinet boxed in — Ranked third on this roster: it worsens in hot weather and in confined spaces, so a cabinet that only misbehaves in summer is pointing straight at it.
- Start components or the sealed system — Ranked last on this roster: a compressor that will not come up, or a circuit that has lost charge, produces a cabinet that is not cold at all rather than one that is not cold enough.
- Body: Where this ranking departs from the brand-generic order is vents blocked by stored food or an overfilled shelf, which moves up on the FKATMP line because this roster is two or three closely related cabinets, so the order follows how those particular machines are built rather than an average across the brand.
Check in this order, and why
- Clear the back of every shelf and find the vents — Leave a hand's width clear at the rear of each shelf, then give the cabinet a day before judging.
- Look at the rear interior wall for a frost sheet — A layer thick enough to hide the surface underneath explains the complaint on its own, and it means the defrost side is worth investigating.
- Clean the condenser and give the cabinet air on every side — With the power off, clear the coil or compartment and pull the cabinet clear. Allow a day before judging the result.
- Have the circuit assessed rather than guessed at — This needs gauges and a licence. Oil on the tubing at the back means the circuit is already open and it should stop running.
Before you open anything
Safety
Switch off at the breaker before any panel comes off and treat the space behind it as live until proved otherwise. Defrost with the doors open and the power off, never with a heat gun or an open flame, and never by chipping at the surface. Keep meltwater away from the supply cord.

When to call a technician
Call when a full defrost, a cleared condenser and a clean paper test have all failed to hold the cabinet for a day, because that pattern eliminates everything an owner can reach. Call sooner if only one compartment is affected and the vents are already clear, because a damper or an interior fan needs a panel off. Either way, move the perishable load first: it will not survive the diagnosis.
