Frigidaire FRSS2623 25.6 cu ft side-by-side refrigerator (FRSS2623AS / FRSS2623AB): quick sheet

Covers: Frigidaire FRSS2623A* 36-inch standard-depth side-by-side with external ice and water: FRSS2623AS (stainless), FRSS2623AB (black) plus white and black-stainless versions; production revisions such as FRSS2623AS6 appear in owner reports. Sold from about 2020; one of the most common big-box side-by-sides.

Cross-checkedBrands: Frigidaire8 components

A value side-by-side with Frigidaire's EvenTemp air circulation, a crescent-cube ice maker in the freezer feeding the door dispenser, a PurePour filter and R-600a refrigerant. Controls are basic (no digital display). Calls are mostly ice maker, frost/defrost and warm fresh food.

Safety first

Unplug before removing covers.
R-600a is flammable: no flames or sparks near tubing; sealed-system work is blocked and goes to an EPA 608-certified technician.
Shut off the water before opening fittings.
Never chip ice off the evaporator.

How it works

Single freezer evaporator: the evaporator fan pushes cold air through the freezer and, via a duct/damper, into the fresh-food side (EvenTemp is Frigidaire's name for this circulation).

Automatic defrost: a heater under the evaporator runs on schedule; a defrost thermostat/bimetal ends it.

Ice: a crescent-cube ice maker with an on/off control fills from the water valve; the bin feeds an auger and the door chute (cubed or crushed).

Alarms: door ajar and power failure alarms; the filter and air-filter indicators are reminders.

Refrigerant is R-600a (isobutane, flammable): sealed system is referral only.

Diagnostic guides for this appliance

Guide · Refrigerator

Adaptive defrost control (ADC) board: how to diagnose it

An adaptive defrost board replaces the old cam timer. It counts compressor run time (and on some boards door-open time) and adjusts the next defrost interval based on how long the last one took. Test the heater and the cold bimetal first, then force a defrost: if the heater warms on a forced defrost but the coil still ices, the board isn't starting defrost on its own.

Ice dispenser not dispensing ice (ice maker is making ice)

Most cases are mechanical: cubes fused into a block, a bin not fully seated on the auger drive, or ice behind the auger motor. After that, check the electrical path: door switch, dispenser switch, auger motor voltage and, on crushed/cubed models, the cube solenoid. Water dispensing working is a useful clue that the dispenser control has power.

Guide · Refrigerator

Refrigerator runs all the time

First decide if it's really a problem. Whirlpool says 40-80% run time is normal at average room temperature, and newer variable-speed compressors are designed to run long at low speed. If it's truly excessive, the usual causes are heat-rejection problems (dirty condenser, dead condenser fan), air leaks (gaskets, doors) and a frosted evaporator. A compressor or refrigerant fault is a referral.
