Refrigerator Not Cooling in Katy: Repair or Replace?

A refrigerator that is not cooling is worth repairing when it is under about 8 years old and the fault is a fan, a defrost part, a thermostat or a gasket. Those repairs cost $100 to $400. Replacement makes more sense when the compressor has failed on a unit past 10 years, because that repair costs $700 to $1,250.

First, protect the food

A closed refrigerator keeps food safe for about 4 hours without cooling, according to the USDA. A full freezer holds for about 48 hours, and a half-full one for about 24. Keep both doors shut. Move milk, meat, eggs and leftovers to a cooler with ice if the fresh food section rises above 40 degrees.

Five checks before you call

These take a few minutes and sometimes solve the problem.

• Power: confirm the light comes on and the breaker has not tripped. After an outage, unplug the refrigerator for five minutes, then plug it back in.
• Settings: make sure the temperature dial or display was not bumped. The fresh food section should be set near 37 degrees and the freezer at 0.
• Vents: look for food packed against the air vents inside. Blocked vents warm the fridge while the freezer stays cold.
• Door seals: close the door on a sheet of paper. If it slides out with no drag, the gasket is leaking.
• Coils: check the condenser coil behind the bottom grille or on the back. A coat of dust or pet hair makes the unit run hot.

What the symptoms point to

The pattern of the failure narrows down the part.

Freezer cold, fridge warm. Cold air is made at the freezer coil and blown into the fresh food side. If the evaporator fan has stopped, or frost has buried the coil, the freezer stays cold while the fridge warms. Look for heavy frost on the back wall of the freezer. The fix is a fan motor or a defrost heater, sensor or control.

Both sections warm, compressor running. The condenser fan may have failed, or the coil is clogged. The compressor runs but cannot shed heat. This is common with a second refrigerator kept in a Katy garage through summer.

Both sections warm, clicking every few minutes. The compressor is trying to start and failing. The start relay is a small part and the first thing tested. If the relay is fine, the compressor itself may be done.

Nothing runs, but the light works. The thermostat or the main control board is not calling for cooling. Boards fail more often after power cuts and surges. Hurricane Beryl left more than 2.2 million CenterPoint customers without power in July 2024, and many refrigerators did not restart cleanly when it returned.

What each repair costs

Typical ranges, parts and labor together:

• Condenser coil cleaning: $70 to $130
• Door seal or gasket: $100 to $300
• Thermostat: $100 to $400
• Defrost heater: $120 to $400
• Condenser fan motor: $200 to $350
• Evaporator fan motor: $250 to $400
• Control board: $400 to $750
• Sealed system repair: $600 to $1,400
• Compressor: $700 to $1,250

Most refrigerator repairs land between $125 and $500. The service call for diagnosis usually costs $70 to $130. Ranges for other machines are listed in appliance repair cost in Katy, TX.

Repair or replace: how to decide

Start with age. Refrigerators last about 9 to 13 years. Find the year on the model tag inside the fresh food section, or look up the serial number on the maker's website.

Then apply the half-price test. If the repair would cost more than half the price of a similar new refrigerator, replacement is usually the better buy.

Put together, the choice looks like this:

• Under 8 years old, fan, defrost, thermostat or gasket fault: repair.
• Under 8 years old, compressor fault: check the maker's warranty first. Some brands cover the compressor for longer than the rest of the unit.
• 8 to 10 years old, repair under $400: usually repair.
• Past 10 years, compressor or sealed system fault: replace.
• Built-in refrigerator of any age: get the estimate. These units cost several times more than freestanding ones, so even large repairs can pay.

A second failure counts too. A refrigerator that needed a fan last year and a board this year is telling you something.

Why sealed system work costs more

The sealed system is the compressor, the coils and the refrigerant that runs through them. Opening it means recovering the refrigerant, brazing in the new part, pulling a vacuum and recharging. Federal rules require a technician to hold EPA Section 608 certification to do that work. It takes hours, which is why the price starts at $600.

When to call

Call when the five checks change nothing, when you hear clicking with no cooling, or when frost covers the freezer's back wall. Have the brand, the model number and the symptom pattern ready. The technician tests the fans, defrost parts, relay and board, and gives a written estimate before any repair begins. For the steps and parts involved, see refrigerator repair in Katy.
