You open the freezer and the ice cream is soft. The ice cubes are melting, or there is a thick sheet of frost on the back wall. A freezer not freezing puts a lot of food at risk, so it is worth acting fast.
This guide explains the 7 most common causes, the checks you can do now, and when to call a pro. For fast help in New Braunfels, call New Braunfels Appliance Fix at (830) 240-5230.
Why is my freezer not freezing?
A freezer stops freezing when cold air cannot reach the food or the system cannot make enough cold. The most common causes are a wrong temperature setting, a door that does not seal, blocked vents, dirty condenser coils, a failed fan, or a defrost problem that covers the coils in frost. A compressor or sealed system fault is less common. Many causes can be checked at home.
First: protect your food
- Keep the door closed as much as you can.
- Move food to a cooler with ice, or to a second freezer, if it is starting to thaw.
- Check the temperature with an appliance thermometer.
- Know the safe limit. The FDA recommends 0°F for the freezer and 40°F or below for the fridge.
7 common causes of a freezer not freezing
1. Wrong temperature setting
Settings get bumped when you load groceries. Make sure the freezer is set to 0°F, or the middle to colder setting on a dial. Give it 24 hours after any change.
2. Door not sealing
A torn, dirty, or loose door gasket lets warm air in. Close the door on a dollar bill. If it slides out easily, the seal is weak. Clean the gasket with warm soapy water, or replace it if it is torn.
3. Blocked air vents
Freezers move cold air through vents, often on the back wall. An overpacked freezer or a bag pushed against a vent can stop the flow. Leave a little space around the vents.
4. Dirty condenser coils
The condenser coils release heat, usually under or behind the fridge. Dust and pet hair make them work harder, which is a big problem in hot New Braunfels summers. Unplug the fridge and vacuum the coils once or twice a year.
5. Failed evaporator fan
The evaporator fan blows cold air from the coils into the freezer. If you do not hear or feel air when you open the door (and press the door switch), the fan may have stopped. This is a common repair.
6. Defrost system failure
Your freezer melts frost off the coils several times a day. If the defrost heater, thermostat, or timer fails, frost builds up until it blocks air flow. A thick, snowy layer on the back wall is the classic sign.
7. Compressor or sealed system problem
If the fridge and freezer are both warm, the condenser fan is running, and the coils are clean, the compressor or refrigerant system may have a problem. This needs a trained technician.

Freezers and Texas heat
Long, hot summers make every freezer work harder. A freezer in a garage that hits 100°F or more may not keep food frozen. Keep the coils clean, leave a few inches of space for air flow, and avoid putting a standard freezer in direct sun. If you rely on a garage freezer, ask about models rated for garage use.
How much does freezer repair cost in New Braunfels?
Our diagnostic visit is approx. $90–$100. It is usually waived or applied to the repair if you go ahead. Labor runs approx. $50–$95 per hour, plus parts if needed. We confirm the total with you before any work starts. Fans, door gaskets, and defrost parts are common repairs. Compressor or sealed system work costs more, so we will help you compare repair and replacement.
Prices are approximate and depend on your freezer’s brand, model, and the part needed.
How to keep your freezer cold
- Keep it about three-quarters full. Frozen food holds cold, but do not block vents.
- Vacuum the condenser coils once or twice a year.
- Check the door seal every few months.
- Let hot food cool before you freeze it.
- Use an appliance thermometer to check 0°F.

Frequently Asked Questions
Why is my freezer not freezing but the fridge is cold?
In most fridges, the cooling coils are behind the freezer wall. If the freezer is warm but the fridge is still cold, the evaporator fan may have stopped, or the coils may be covered in frost from a defrost problem. A thick sheet of frost on the back wall is a strong sign of a defrost failure.
Why is there frost building up in my freezer?
Frost forms when warm, humid air gets in. Common causes are a torn door gasket, a door left open, or a failed defrost heater, thermostat, or timer. A small amount of frost is normal. A thick layer on the back wall or on food is not.
What temperature should my freezer be?
Your freezer should be at 0°F, and your fridge at 40°F or below. Use an appliance thermometer to check, because the dial numbers on many fridges are not actual temperatures.
Is it safe to eat food from a freezer that stopped freezing?
Food that still has ice crystals or is at 40°F or below can usually be refrozen. Food that has been above 40°F for more than 2 hours should be thrown out. When in doubt, throw it out.
How much does freezer repair cost in New Braunfels?
Our diagnostic visit is approx. $90–$100, usually applied to the repair. Labor runs approx. $50–$95 per hour plus parts. Fans, door gaskets, and defrost parts are common repairs. Sealed system work, like a compressor, costs more. You get the price before work starts.
Does a freezer work in a hot garage?
Many standard freezers struggle when a Texas garage gets above 100°F in summer. The compressor runs nonstop and food may not stay frozen. Look for a model rated for garage use, and keep space around it for air flow.
