Common Freezer Part Failures

A freezer that's not freezing is almost always one of a few key parts. The evaporator fan motor circulates cold air from the compressor throughout the cabinet — if it fails, you'll see frost buildup in the evaporator coil and warm temperatures everywhere. The defrost heater and defrost thermostat work together to melt frost periodically; when they fail, ice accumulates and airflow stops. A temperature sensor (thermistor) tells the control board what temperature the freezer is — bad readings cause the compressor to run constantly or shut off too early.

Door gaskets that no longer seal tight force the compressor to work overtime, and start relays that fail prevent the compressor from starting at all. We carry OEM replacement parts for all major brands — freezer parts from, and more. Enter your model number to find the exact part your freezer needs.

• Evaporator fan motor: Freezer not cold, loud humming, or frost buildup in coils
• Defrost heater and thermostat: Ice buildup, frost on evaporator, reduced cooling
• Temperature sensor (thermistor): Wrong temperature display, compressor runs constantly or won't start
• Door gasket/seal: Frost forming on door edges, moisture inside, energy loss
• Start relay (compressor): Compressor clicks but won't run, or won't start at all

Freezer Part Repairs: Frequently Asked Questions

Why is my freezer not freezing if the compressor is running?

If you hear the compressor running but the freezer stays warm, the problem is usually airflow or circulation. The evaporator fan motor pushes cold air from the evaporator coils into the freezer compartment — when that motor fails, the compressor still runs but cold air doesn't reach the food. Check the evaporator coils for heavy frost (a sign the defrost cycle is failing) and listen for the fan motor. If the motor is silent, that's your part. You may also have a blocked or kinked defrost drain line preventing the defrost cycle from working.

What does a temperature sensor do, and how do I know if it's bad?

The thermistor (temperature sensor) tells your freezer's control board how cold it is inside. When the sensor fails or gives false readings, the board can't regulate the compressor correctly — you might see constantly running compressor cycles, or the freezer might not cool at all. Use your model number to find the exact thermistor location and resistance values. If your digital display shows a wrong temperature or the compressor behavior seems erratic, the thermistor is worth checking before replacing the control board.

How do I find my freezer model number for parts?

The model number is almost always on a sticker inside the freezer — check the side wall, back wall, or the inside of the door. Write down the full model number (it often starts with letters like WRT, LRMVS, or FFFU). Snap a photo with your phone. Enter that number into Repair Clinic's model lookup, and you'll see exactly which parts fit your freezer, including evaporator fans, door gaskets, thermistors, and compressor relay assemblies.

Is a freezer door gasket repair worth doing, or should I replace the freezer?

A door gasket is almost always worth replacing. A worn or torn seal lets warm air leak in constantly, forcing the compressor to work overtime and raising energy bills. A new OEM gasket costs $30 to $80 and takes 10 minutes to install — it's one of the easiest and most cost-effective freezer repairs. A new freezer costs $800 to 2,000+, so a freezer gasket replacement pays for itself in energy savings within a year or two.

Where to Find Your Freezer Model Number

Check the inside wall of your freezer compartment for the model number label, usually near the top or side. If you do not see it there, look behind the crisper drawer or on the back of the unit. Copy the complete model number, including any letters, numbers, and separators, then enter it in the model number search to pull up the parts matched to your unit. The model number applies to the entire freezer, so it filters the catalog across every associated part category, from gaskets and shelves to thermostats and ice makers. You get a faster, more accurate match and fewer wrong orders.
