Understanding the Problem
Brief overview: Sears Coldspot side‑by‑side refrigerators (Sears-branded units often built by larger manufacturers) commonly show a handful of repeat problems: fridge not cooling while freezer is cold, excessive frost on evaporator, ice maker/water dispenser failures, leaks, and unusual noises. Below are prioritized diagnostic steps and practical repair actions you can perform. 1) Identify model and baseline checks - Find the model & serial tag (inside fridge compartment on side or wall, or behind crisper). Write it down before ordering parts. - Verify basic settings: temperature dials should be 37°F (fridge) / 0°F (freezer) or manufacturer's recommended settings. Ensure doors close fully and gaskets seal. 2) If the fridge is not cooling (freezer cold / fridge warm or both warm) - Check airflow: remove items blocking vents between freezer and fresh food. Ensure evaporator fan runs when doors are closed (press door switch to test). - Clean condenser coils: unplug unit, pull fridge forward, use brush/vacuum to remove lint/ dust from coils and surrounding area. Dirty coils reduce cooling efficiency. - Check condenser fan and evaporator fan: with unit unplugged, remove grille/panels and spin fans by hand; inspect for obstructions and test motor continuity with a multimeter. Replace if noisy, seized, or no continuity. - Listen to compressor and start relay: if compressor hums or clicks repeatedly and fridge doesn't cool, the start relay/overload may be faulty. To test: unplug, remove relay from compressor, test for continuity or replace with known good. Replace relay if it has no continuity or is burnt. A bad relay often causes clicking or a humming that stops. - Check evaporator for frost: excessive frost on evaporator suggests defrost system failure (defrost timer/control, defrost heater, or defrost thermostat/thermistor). Enter diagnostics if model supports it or visually inspect: heavy frost means defrost components need testing. 3) Diagnosis and repair for defrost failure (excessive frost / freezer cold, fridge warm) - Inspect evaporator: remove back freezer panel to view evaporator. If covered in thick frost, defrost system isn't working. - Test defrost heater for continuity with a multimeter; replace heater if open. - Test defrost thermostat (bi-metal) for continuity when cold (below ~40°F); replace if open when cold. - If equipped with an electronic control/thermistor, check for stored error codes or test thermistor resistance vs. temperature. Replace failed thermistor or control board if necessary. - Temporarily defrost (hair dryer / let unit sit unplugged) to clear frost, then repair the failed component to prevent recurrence. 4) Ice maker / water dispenser problems - If ice maker not filling: check water supply valve at wall, water inlet valve on fridge (usually behind lower rear). Test inlet valve solenoids for continuity; replace valve if defective or slow filling due to low pressure. - Change the water filter (if equipped). A clogged filter will reduce or stop fill. - If dispenser is weak or noisy, ensure lines are not kinked and the inlet valve has full household water pressure. - Ice maker assembly: test the ice maker module with the test/diagnostic switch (if present) or activate manually. Replace ice maker if it does not cycle or will not call for water when commanded. 5) Leaks and clogged defrost drain - Common leak cause: clogged/ frozen defrost drain in freezer causing water to run into lower pan or onto floor. Locate drain at back of freezer evaporator, remove ice blockage, and clear with warm water or a flexible tube/pipe cleaner. - Check water inlet and dispenser hoses for cracks and tighten connections. - Inspect drain pan under refrigerator for cracks or overflow; position and replace if damaged. 6) Unusual noises (buzzing, clicking, rattling) - Buzzing/clicking: start relay on compressor, condenser fan motor, or blocked fan blades. Isolate by turning off power and stopping each fan to see if noise stops. - Rattles: fan hitting wire or debris on condenser coils—clean and reposition items. - Squeals: fan motor bearings wearing out—replace fan motor. 7) Basic replacement steps (general safe method you can apply to most parts) - Always unplug the refrigerator before any repair. - Move fridge away from wall and remove access panels (rear bottom for compressor/relay, freezer back panel for evaporator/defrost parts, lower front grille for condenser components). - Take pictures of wiring/part orientation before removal. - Disconnect connectors (note plastic clips), remove mounting screws, swap part, reattach connectors and panels, push fridge back, plug in, and monitor for proper operation. Safety note: Always unplug the appliance before accessing electrical components. If you are not comfortable working with sealed system components (compressor or refrigerant), call a certified appliance technician—compressor replacement or refrigerant work requires EPA‑certified service technicians.
Common Symptoms
Fridge warm while freezer cold; both compartments not cooling; excessive frost on evaporator; ice maker not filling; water dispenser weak or leaking; loud humming or clicking noises; water leaking onto floor.
Common Causes
- Dirty condenser coils or blocked airflow
- Faulty compressor start relay/overload or failed compressor
- Defrost system failure (heater, thermostat, or control)
- Bad evaporator or condenser fan motor
- Clogged defrost drain or damaged drain pan
- Faulty water inlet valve, clogged filter, or low water pressure

Helpful Repair Tip
If the compressor clicks on/off or hums but fridge doesn't cool, the compressor start relay/overload is the most likely culprit—listen at the rear for repeated clicking and check/replace the relay first.
Frequently Asked Questions
Where do I find the Sears Coldspot model number?
The model and serial tag is usually inside the fresh food compartment on the left or right side wall, behind the crispers, or on the ceiling of the fridge. Some models have the tag on the back exterior. Pull out drawers if needed and look for a white or silver sticker with 'Model' and 'Serial'.
Is it worth repairing an old Sears Coldspot side-by-side refrigerator?
It depends on the age and the failed component. Replacing a start relay, fan motor, defrost heater, or water inlet valve is usually cost-effective. If the compressor or sealed system needs replacement, repair cost can approach the price of a new unit — consider refrigerator age (10+ years often means replacement is more economical). Always get a quote and weigh repair cost vs. replacement energy savings.
