Understanding the Problem
About this model and common problems: The KitchenAid KSRS25FGBT03 is a side-by-side/similar KitchenAid refrigerator that can show typical faults: uneven cooling, freezer frosting over, water leaks, noisy fans/compressor, and ice maker or water-dispense failures. Below are prioritized diagnostic and repair steps for each common symptom with practical "how-to-fix" actions. 1) Fridge or freezer not cooling (or warm): 1.1 Verify temperatures and load: set controls to recommended temps (fridge 37°F, freezer 0°F). Leave closed for 24 hours and check again. 1.2 Check power and basic operation: confirm the unit has power, interior lights cycle and fans run. If nothing runs, check outlet and house breaker. 1.3 Clean condenser coils: unplug fridge, pull unit forward, vacuum/brush the coils and the condenser fan area — dirty coils will impair cooling. 1.4 Confirm condenser fan operation: with power on and door closed, observe or feel for the condenser fan running; replace if seized. 1.5 Confirm evaporator fan operation: open freezer, press door switch (if installed) or start diagnostics and listen for the evaporator fan. Replace if noisy or not running. 1.6 Inspect evaporator for frost/ice: remove freezer back panel (after unplugging), look for heavy frost on the evaporator — if present, likely defrost failure. 1.7 Test defrost components: with freezer panel removed, test defrost heater and defrost thermostat/thermistor for continuity with a multimeter; if heater or thermostat open, replace. 1.8 Check start relay/overload and compressor: with power on, listen for compressor hum and fans; if compressor clicks and won’t run, test/replace start relay or overload. If compressor is dead, replace compressor (technician recommended). 1.9 If control board or thermistor faults are suspected, check error codes (if unit displays them) and consider replacing the main control board or thermistor after confirming with multimeter readings and visual inspection. 2) Freezer frosting over or excessive ice build-up: 2.1 Manually defrost: remove food, unplug and leave doors open or use warm water to melt ice. Clear the defrost drain if flooded. 2.2 Verify door seals: inspect gaskets for cracks, gaps or debris; replace if they leak cold air. 2.3 Test defrost system: after thaw, run a manual defrost cycle or place unit in diagnostic mode to energize defrost heater; if heater does not heat, replace defrost heater or thermostat/thermistor. 3) Water leaks or clogged drain: 3.1 Check drain pan and defrost drain: locate the defrost drain at the freezer evaporator and clear any clogs with warm water and a small brush or compressed air from the cabinet side. 3.2 Inspect water line and water inlet valve (for fridge/ice maker): check the valve under the fridge for leaks; tighten or replace as needed. 3.3 Check ice maker fill tube and hoses for cracks. 4) Ice maker or water dispenser not working: 4.1 Confirm water supply: ensure the shutoff valve to the fridge is open and there is water pressure. 4.2 Inspect/replace water filter: a clogged filter will reduce flow — replace if overdue. 4.3 Test water inlet valve: verify voltage to the valve during a dispense; if no water, valve may be faulty and should be replaced. 4.4 Inspect ice maker interface: check wiring and test the ice maker module for continuity; replace ice maker assembly if defective. 5) Noisy operation (fans, hum, knocking): 5.1 Identify noise source: determine if noise is from evaporator fan (inside freezer), condenser fan (bottom rear), or compressor (back of unit). 5.2 Replace or lubricate fan motors if they are noisy or wobbling; replace compressor mounting/isolators if knocking occurs. Step-by-step replacement example — evaporator fan motor (common DIY): A. Unplug refrigerator and remove all food from freezer. B. Remove shelving and the freezer back access panel (typically 6–8 screws). C. Unplug the fan motor connector and remove mounting screws; note blade orientation to avoid imbalance when reassembling. D. Install new motor, reconnect the plug, reassemble panels and restore power. Confirm fan runs and cooling resumes. Step-by-step replacement example — defrost heater/thermostat: A. Unplug fridge and empty freezer compartment. B. Remove freezer back panel to expose evaporator and heater assembly. C. Test heater continuity with a multimeter. If open, remove clips or screws holding heater and thermostat and replace the assembly. D. Reassemble and power on. Allow several hours to confirm no reoccurrence of heavy frost. Safety note: Always unplug the refrigerator before opening access panels or testing for continuity. Use insulated tools and measure voltages only when you are confident and follow local electrical safety practices. For sealed-system (compressor) repairs or refrigerant work, hire a certified refrigeration technician (EPA certification required in many regions).
Common Symptoms
Fridge or freezer not cooling, freezer frosting over, water leaking from the bottom, reduced/absent water or ice dispense, loud fan/compressor noises.
Common Causes
- Dirty condenser coils or failed condenser fan causing poor heat rejection
- Evaporator fan motor failure preventing cold-air circulation
- Defrost system failure (heater, thermostat or control) causing heavy frost on evaporator
- Faulty start relay/overload or compressor problems
- Clogged defrost drain or damaged door gaskets causing leaks and frost
- Water inlet valve or water filter problems affecting ice maker and dispenser
- Control board or thermistor failure causing incorrect temperature regulation

Helpful Repair Tip
To confirm the defrost system is at fault: thaw the evaporator, then force a short run (or enter service mode) and measure continuity on the defrost heater and thermistor; an open heater or out-of-spec thermistor is a strong indicator of defrost failure.
Frequently Asked Questions
Why is my KSRS25FGBT03 cold on one side but warm on the other?
This often means poor airflow between compartments or a failed fan. Check that the evaporator fan in the freezer is running (it distributes cold air). Also inspect the damper or air baffle between freezer and fridge for blockage, and confirm no heavy frost is preventing airflow. Clean coils and verify condenser fan and compressor run properly.
How do I force a manual defrost if the freezer is iced over?
Safe manual defrost: remove food, unplug the fridge, leave doors open and let ice melt naturally or speed melting with containers of warm (not boiling) water placed in the freezer. Clear the defrost drain with warm water and a pipe-cleaner. After thawing, power on and monitor — if ice returns quickly, test and replace defrost components (heater, thermostat, or control board). For entering service/diagnostic mode, consult the KitchenAid service manual for model-specific button sequences or contact KitchenAid support.
