What this usually is
An Arctic Wind ABMSLB refrigerator that has stopped holding temperature is worth triaging before it is worth repairing. The roster covers two models, ABMSLB141E and ABMSLB170E. A refrigerator holds food safely at 40 degrees Fahrenheit or below and a freezer at 0 degrees Fahrenheit or below, so the first useful action is a thermometer in each compartment rather than a screwdriver.
What the cabinet is doing
- The refrigerator section is warm but the freezer is still cold — The classic airflow split on this cabinet type. Cold is being made and is not reaching the fresh-food side, which points at the duct or the fan rather than the sealed system.
- The cabinet cools again for a day after being emptied and left open — A strong sign of ice on the coil: the manual defrost cleared it, and the underlying reason it formed is still there.
- NEAR MISS - the cabinet is cold but water is pooling inside — A blocked defrost drain with cooling intact belongs on the water-leak page for this family.
Causes, most likely first on this roster
- Frost across the evaporator blocking airflow — First on this roster. Adaptive defrost stalls quietly rather than failing outright, so ice builds across the coil over weeks. Air stops passing, the fresh-food side warms first, and the compressor runs on without ever reaching its set point.
- Condenser coil or machine-compartment airflow blocked — Common in kitchens where the unit sits on carpet or in a tight surround. The fix is a vacuum, a brush and clearance, and it is the only entry here that also reduces running cost.
- Control, thermistor or damper fault — This is the entry that explains a cabinet where everything visible is correct. On this roster it is uncommon but it is not rare, and it is the point at which owner diagnosis usually runs out.
- Compressor, start relay or sealed-system fault — At the bottom because this is where the money is. Every entry above it is cheaper to test, and a wrong guess here is the difference between a service call and a new appliance.
- Body: This order is by finding frequency, not by part cost. The first three entries account for the large majority of warm-cabinet calls on cabinets laid out like the ABMSLB listings, and none of the three requires the sealed system to be touched.
Diagnostic order on these models
- Put a thermometer in each compartment and wait — A refrigerator holds food safely at 40 degrees Fahrenheit or below and a freezer at 0 degrees Fahrenheit or below. Knowing which compartment is actually failing decides everything that follows.
- Listen for the evaporator fan with the door open, then closed — The door switch gives you a free test of whether cold air is being moved at all.
- Body: Follow this in sequence and resist skipping to the sealed system. On cabinets of this type the last step on the list is reached in a small minority of cases, and reaching it early costs money that the first three steps usually save.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before any panel is removed; a capacitor can hold a charge after the power is off. If you see oil anywhere in the machine compartment, stop and call - oil outside the tubing means the sealed system is open, and running the unit after that point makes the repair larger.
Models in the ABMSLB family — This page generalizes over every listing in the roster below; where the models diverge for this fault the text says so, and where it does not, they behave alike.

When this stops being an owner job
Call once the thermometer, the seal check and the vent check are clean and the cabinet is still warm. On the ABMSLB roster the next step is the liner panel, which means an emptied compartment and exposed fins. Call immediately if the compressor is hot and silent, if a relay is clicking repeatedly, or if there is oil in the machine compartment.
