Why does my side-by-side show frost on the back wall but the refrigerator stays warm?

This pattern usually indicates a defrost heater, thermostat or control board that is no longer cycling properly, allowing ice to block airflow to the fresh-food section.

Can you repair the ice maker on my side-by-side without replacing the entire unit?

Yes, we commonly replace the water inlet valve, fill cup or the ice maker module itself after confirming the exact cause of the stoppage.

Do garage side-by-sides in Buffalo Grove need special handling during cold months?

Units stored in unheated garages experience more frequent defrost issues because low ambient temperatures affect the defrost timer and heater operation.

What causes water to appear under the crisper drawers on side-by-side models?

A clogged defrost drain or faulty defrost components allow meltwater to overflow into the refrigerator section instead of draining to the pan.

Side-by-Side Refrigerator Repair in Buffalo Grove, IL

Side-by-side models in Buffalo Grove often show warm refrigerator sections while the freezer stays cold when the evaporator fan motor fails or the thermistor sends bad readings to the control board. Our technicians start by checking door gaskets for proper seal on these wider units, then test the start relay and compressor operation. In 1960s-1990s ranches and colonials along Lake Cook Road or in Old Farm Village, we also inspect for power flicker damage from summer thunderstorms that trips the defrost control board. Repairs focus on replacing the exact failed component after isolating it with multimeter checks.

Frost buildup along the back wall or water under the crisper drawers usually traces to a clogged defrost drain or faulty defrost heater and thermostat in side-by-side units common to Woodstone and The Woodlands neighborhoods. We remove the rear panel, verify the timer or adaptive defrost board, and clear the drain tube that often freezes during long sub-freezing stretches. In attached garages of newer Lake County homes, winter temperatures can push garage refrigerators into inefficient cycles, so we confirm the unit is rated for unheated spaces before completing the repair.

Ice maker not making ice or a leaking water dispenser on French-door side-by-sides frequently stems from a worn water inlet valve or restricted filter housing, especially in homes near Buffalo Creek or Prairie View Park. Our technicians trace the line from the valve through the door hinge, test voltage at the solenoid, and replace only the defective part. In finished basements with bar fridges or condos off Milwaukee Avenue, we also check the temperature control board that governs both compartments to prevent food spoilage after outages.

Technician insight

In Buffalo Grove the thing that catches most people out with Side-by-Side Refrigerator Repair is how the attached garages on 1970s-80s split-levels let winter temperatures reach the secondary fridge or chest freezer, triggering repeated defrost cycles that kill the heater and thermostat faster than in heated kitchens.

Frost Buildup After Power Flicker

A side-by-side in an Old Farm Village ranch showed heavy frost and warm refrigerator air following a summer storm outage. We found the defrost control board had failed to cycle the heater. Replacing the board and clearing the drain restored proper defrosting and even temperatures.

Side-by-Side Refrigerator Repair Services We Offer

✓Evaporator Fan Motor Replacement

Restores even cooling across both compartments by installing a new evaporator fan motor matched to the side-by-side model.

✓Defrost Heater and Thermostat Service

Eliminates frost buildup and water leaks by testing and replacing the defrost heater, thermostat or adaptive control board.

✓Ice Maker and Water Dispenser Repair

Fixes ice production and dispensing problems by diagnosing the inlet valve, fill tube and related components on side-by-side units.

✓Door Gasket and Seal Inspection

Stops warm air intrusion and frost issues by replacing worn or torn door gaskets that no longer seal properly on wider side-by-side doors.

✓Condenser Coil and Fan Cleaning

Improves efficiency and reduces compressor strain by clearing dirt from coils and testing the condenser fan motor in humid summer conditions.

How it works

1
Symptom Assessment
We review the specific symptoms such as warm sections, frost patterns or ice maker failure while noting the model and age of the side-by-side unit.
2
Component Testing
Our technicians use diagnostic tools to check the evaporator fan, defrost system, thermistor and control board for the exact point of failure.
3
Targeted Repair
We replace only the failed part, such as a defrost timer or water inlet valve, and verify operation across both refrigerator and freezer sides.
4
Final Verification
We confirm temperatures stabilize correctly and test all functions including the ice maker before completing the service call.

What's Included in the Visit

Full cooling system diagnostic

We test compressor windings and amp draw, check refrigerant pressures with a manifold gauge set, and inspect the evaporator and condenser coils.

Ice maker and water valve service

We diagnose the ice maker assembly, test the water inlet valve for proper flow, and check the fill tube for ice blockages. Most ice maker faults come down to the valve or the assembly itself, and both are parts we carry.

Door gasket and seal replacement

A torn or stiff door gasket lets cold air escape and makes the compressor run constantly. We fit a new gasket, check the door alignment, and confirm the seal with a dollar-bill test before we call the job done.

Tools and Methods We Use

Multimeter

Tests voltage and continuity at the compressor, defrost heater, thermostat, and control board. This is how we confirm which component has actually failed instead of replacing parts by guesswork.

Manifold gauge set

Reads high-side and low-side refrigerant pressures so we can tell whether the system is undercharged, overcharged, or restricted. Essential for diagnosing a sealed-system fault.

Leak detector

Finds refrigerant leaks at joints, the evaporator coil, and the compressor fittings. A slow leak explains a fridge that cools weakly and then stops altogether.

Fin comb and coil brush

Straightens bent condenser fins and clears dust matting. A dirty condenser coil is one of the most common causes of poor cooling and high energy use.

Load-based electrical testing

We test components under load, not just for continuity. A compressor that reads fine on a static test can still fail under running amps, and load testing catches that before we reassemble the unit.
