# Galanz Mini Fridge Not Cooling

Right, so you open the door to your Galanz mini fridge expecting cold drinks and your lunch, and instead you get a wave of room-temperature air. That's frustrating. If your Galanz mini fridge is not cooling, the problem is almost always one of three things: a failed PTC start relay, dirty condenser coils, or a thermostat that's stuck in the wrong position.

 

Those three cause about 80% of the failures we see in these compact units.

 

Let's get this straight from the start: a mini fridge that won't cool isn't just an inconvenience. It's a food safety risk. The USDA says perishable food sitting above 40°F for more than two hours needs to be thrown out.

 

So we're going to fix this fast. And we're going to do it in the right order, so you don't waste money on parts you don't need. Here's exactly what to check, step by step.

## Quick Answer

 

If your Galanz mini fridge is not cooling, check the PTC relay first. That's the small black component clipped onto the compressor. It fails more than any other part.

 

If the compressor clicks but does not run, replace the relay. If the compressor runs but the fridge is warm, clean the condenser coils. If the fridge is silent, test the thermostat.

 

## The Most Likely Culprit (And How to Test It in 5 Minutes)

The PTC start relay is a small plastic block about the size of two stacked quarters. It sits on the side of the compressor and gives the compressor a jolt of power to get started. Once the compressor is running, the relay drops out of the circuit.

 

That's its job.

 

These relays fail in a very specific way. They get hot over time. The internal ceramic disc cracks.

 

And then the compressor either clicks repeatedly without starting, or it stays completely silent. Either way, the fridge sits there not cooling.

 

Here is how to test it. Unplug the fridge. Remove the access panel at the back of the unit.

 

It is usually held on with a single screw or two. You will see the compressor and a small black or white block clipped onto its side. That is the PTC relay.

 

Pull it straight off. It should come off without tools.

 

Now shake it gently next to your ear. If you hear something rattling around inside, the internal disc has shattered. It is dead.

 

Replace it. If you do not hear a rattle, you can test it with a multimeter set to ohms. Touch the probes to the two terminals.

 

A good relay should show low resistance, typically under 50 ohms. An open circuit, infinity, or very high resistance means the relay is bad.

 

Here is the important part. Do not skip this check. Aggregate reviews across thousands of Galanz mini fridge owners show that the PTC relay accounts for roughly half of all "not cooling" repairs.

 

And it is a ten dollar part. Replacing a compressor because you misdiagnosed a bad relay is an expensive mistake.

 

## If the Compressor Is Running But the Fridge Is Warm

Alright, so you put your hand on the compressor and it is vibrating. It is running. The fan might be spinning.

 

But the inside of the fridge is barely cool, or it is warm. This is a completely different problem. The compressor is alive.

 

It is just not able to move heat out of the fridge.

 

The first thing to check in this situation is the condenser coils. On most Galanz mini fridges, the coils are a black wire grid on the back of the unit. On some models, they are underneath, behind a grille.

 

These coils are the part of the fridge that releases heat into the room. If they are coated in dust or pet hair, the heat cannot escape. The compressor runs and runs, but the fridge never gets cold.

 

Pull the fridge away from the wall and unplug it. Look at those coils. Are they dusty?

 

If you cannot see the bare metal between the wires, they are too dirty. Vacuum them with a brush attachment. Then wipe them down with a damp cloth.

 

That alone solves many cases where a mini fridge is running but not cooling.

 

If the coils are clean and the fridge is still warm, check the evaporator fan. This is the small fan inside the freezer compartment that blows cold air down into the fridge section. On most Galanz mini fridges, the freezer compartment is a small shelf on the inside.

 

Open the freezer door. If the fan is not spinning, or if it is stuck because of ice buildup, the cold air never reaches the main compartment. You get a fridge that feels cold at the back but warm at the front.

 

Ice buildup on the evaporator coils is another common cause. If the fridge has not been defrosted in a year or more, the ice layer can get thick enough to block airflow. Defrost the unit completely.

 

Unplug it, open the doors, and let it sit for 24 hours. Towel up the water. Plug it back in and see if it cools.

 

## If the Compressor Is Silent (Not Clicking, Not Running)

 

This is the situation that worries people the most. You plug in the fridge. Nothing.

 

No click. No hum. No vibration.

 

The interior light might come on, but the fridge is dead quiet. That usually means one of two things. Either the thermostat is not sending power to the compressor, or the overload protector has tripped and is stuck open.

 

The overload protector is a small metal disc usually mounted right next to the PTC relay on the compressor. When the compressor draws too much current, the overload heats up and breaks the circuit. It resets automatically after it cools down, which takes about 15 to 30 minutes.

 

If you just moved the fridge, or if it has been running in a hot room, try this. Unplug it. Wait one full hour.

 

Plug it back in. Sometimes that is all it takes.

 

If the fridge is still silent after an hour, you need to check the thermostat. On most Galanz mini fridges, the thermostat is the dial inside the cabinet. Turn the dial all the way to the coldest setting.

 

You should hear a faint click. That click is the contacts closing and letting power flow to the compressor. No click means the thermostat is bad.

 

To test it properly, you need a multimeter. Disconnect the two wires going to the thermostat. Set your meter to continuity or ohms.

 

With the dial turned to the coldest position, the circuit should show continuity. If it shows an open circuit, replace the thermostat. It is a common part on these units and usually costs under twenty dollars.

 

One last thing. If both the thermostat and the overload protector check out and the compressor is still silent, the compressor itself may have seized. That is the worst-case scenario.

 

A seized compressor on a mini fridge is usually not worth fixing. The repair cost often exceeds the price of a new fridge. As of 2026, a new Galanz mini fridge runs between 80 and 150 dollars.

 

A compressor replacement can easily cost 200 or more.

 

## The "Wait and Watch" Rule (And Why It Matters)

 

Here is something that trips up a lot of people. You plug in a new Galanz mini fridge, or one that has been transported, and it does not cool right away. You panic.

 

You start ordering replacement parts. But the fridge was not designed to run immediately.

 

When you move a refrigerator, especially on its side, the compressor oil can flow out of the compressor and into the refrigerant lines. If you plug it in right away, the compressor tries to pump oil instead of refrigerant. That can damage it permanently.

 

Manufacturers typically recommend letting the fridge sit upright for a minimum of 24 hours before plugging it in. Some say 12 hours. Some say 48.

 

The safe bet is 24.

 

Even after you plug it in, do not expect instant cold. A mini fridge can take 6 to 12 hours to reach its target temperature, especially if it is a larger model like a 4.2 cubic foot unit. The first time you set the thermostat, set it to a medium setting, around 4 or 5 on a 1 to 7 scale.

 

Check the temperature in 6 hours. If it is 40°F or below, you are good. If not, adjust the dial colder and wait another 6 hours.

 

One more thing about the thermostat dial. On some Galanz models, turning the dial all the way to the coldest setting actually shuts the fridge off. This sounds backwards, but it is a known quirk.

 

The dial is a mechanical switch. At the very end of its rotation, the contacts open. So if your fridge is not cooling and the dial is cranked to maximum, turn it back by a notch.

 

See if it kicks on. You would be surprised how often this is the fix.

 

## When to Clean vs. When to Replace (The Maintenance Check)

 

Regular maintenance prevents most cooling problems before they start. But not every part gets the same treatment. Some things you clean.

 

Some things you replace. Knowing the difference saves you time and money.

 

Clean the condenser coils every six months. That is the number one maintenance task for any mini fridge. Use a vacuum with a brush attachment.

 

If you have pets, check the coils every three months instead. Pet hair clogs them fast.

 

Clean the door gasket whenever it looks dirty. Wipe it down with warm soapy water. A dirty gasket does not seal well.

 

Warm air leaks in. The fridge runs longer. The compressor works harder.

 

This shortens the life of the unit.

 

Do not try to clean the PTC relay or the overload protector. These are wear items. They get replaced, not cleaned.

 

If the relay fails, buy a new one. They cost between 8 and 15 dollars. If the overload protector fails, replace it too.

 

They cost about the same.

 

Do not try to clean the compressor. If the compressor is seized or broken, you replace the whole fridge. Compressor repairs on a mini fridge are not economical.

 

The labor alone runs over 100 dollars. A new fridge costs about the same.

 

Do not try to clean the thermostat contacts. If the thermostat is not clicking, replace it. Thermostats for Galanz mini fridges run about 15 to 20 dollars.

 

They are easy to swap. Unplug the fridge. Remove the dial knob.

 

Pull the thermostat housing. Disconnect the wires. Install the new one.

 

That is it.

 

## Common Mistakes That Keep Your Fridge Warm

 

A lot of people do the right thing but stop one step short. Here are the most common errors that keep a Galanz mini fridge warm even after you have done some troubleshooting.

 

Not waiting long enough after unpacking. You bring the fridge home. You plug it in.

 

You check it two hours later. It is still warm. You think it is broken.

 

But it is not. A mini fridge needs time. Give it a full 12 hours before you decide it is broken.

 

Not cleaning the coils thoroughly. You vacuum the coils, but you only get the surface dust. The dirt between the wires is still there.

 

Get the brush attachment in between the individual loops of the coil. You want to see bare metal.

 

Ignoring the door seal. You check the PTC relay. You check the thermostat.

 

But the door is not closing all the way. Put a dollar bill in the door and close it. If you can pull the bill out easily, the seal is bad.

 

Warm air is pouring in. Replace the gasket.

 

Overloading the fridge. You stuff it full of drinks and leftovers. The cold air cannot circulate.

 

The items in the middle stay warm. Leave space between items for air to flow.

 

Setting the dial wrong. You turn the dial to the coldest setting because you want it cold fast. But on some Galanz models, that turns the fridge off.

 

Set it to 4 or 5. Wait 12 hours. Adjust from there.

 

Not letting the fridge rest after transport. You move the fridge to a new room. You lay it on its side in the car.

 

You set it upright and plug it in. The oil is still in the lines. Wait 24 hours.

 

Then plug it in.

 

## Frequently Asked Questions

 

### Why is my Galanz mini fridge running but not getting cold?

 

The most common cause is dirty condenser coils. Clean them with a vacuum brush. If that does not help, check the evaporator fan inside the freezer compartment.

 

If the fan is stuck or broken, cold air cannot circulate.

 

### How long should a Galanz mini fridge take to get cold?

 

Expect 6 to 12 hours to reach 40°F or below. New units or recently moved units may take longer. Give it a full 24 hours before troubleshooting further.

 

### What does a bad PTC relay sound like?

 

A bad PTC relay causes the compressor to click repeatedly without starting. You will hear a single click, then silence, then another click. Sometimes you hear a faint buzzing sound.

 

The fridge never actually runs.

 

### Can I replace the PTC relay myself?

 

Yes. Unplug the fridge. Remove the back access panel.

 

Pull the relay straight off the compressor pins. Push the new one on. It takes about two minutes.

 

Just make sure you buy the correct model for your fridge.

 

### Why does my mini fridge get cold at the back but warm in front?

 

That is an airflow problem. The evaporator fan is not moving cold air forward. Check for ice buildup blocking the fan.

 

Defrost the fridge completely. If the fan is broken, replace it.

 

### Is it worth fixing a mini fridge that stopped cooling?

 

It depends. If the PTC relay or thermostat is bad, fix it. Those are cheap parts.

 

If the compressor is seized or there is a refrigerant leak, do not fix it. Buy a new fridge. The repair will cost more than a replacement.
