Cellar Cooling Unit Fan Not Running

A cellar cooling unit fan not running leaves the cellar-side grille still and silent while the compressor hums, or leaves the exhaust side quiet and the unit hot to the touch.

What it
usually means.

Most cellar units have two fans. The evaporator fan on the cellar side pushes room air through the cold coil and spreads it among the racks; the condenser fan on the hot side pulls air through the hot coil and carries the heat away. Many controllers also run the cellar-side fan on its own between cooling runs to keep the air moving and to thaw the coil. When the cellar-side fan stops, the coil ices and the room warms; when the hot-side fan stops, pressures and temperatures climb until the compressor shuts itself off. Fans stop because their bearings dry out, a blade is jammed by ice or debris, a motor winding fails, or the controller or a capacitor no longer sends them power. Some fans are meant to rest at times, so check the pattern before assuming it is broken.

Answer these first

01

Which fan has stopped: the one behind the cellar-side grille, or the one on the exhaust side?
02

Does the compressor hum while the fan is still?
03

Is there ice on the cellar-side coil?
04

Does the blade turn freely if you look closely with the unit off, or is it blocked?
05

Did the fan make a grinding or squealing sound before it stopped?

Cellar cooling unit fan not running: 5 checks, and none of them costs anything.

01

Keep the cellar door shut; if the room passes about 70°F, move the most valuable bottles to the coolest dark place in the house.

02

Turn the unit off from a dry panel before looking closely at a fan, and never reach into a grille.

03

Look for ice on the cellar-side coil and let it thaw if there is any.

Also worth checking

  • Watch the fans through one full cooling run to see whether one stays still the whole time.
  • Tell us the make, the model number and which side's fan has stopped.

How soon does it need a visit?

A stopped fan will soon lead to a warm cellar or an overheated compressor. Book within a few days, and treat it as urgent if the cellar starts warming.

4 things cellar cooling unit fan not running turns out to be, from fan resting by design to fan capacitor or controller output failed.

The cost guide
  1. 01 no repair

    Fan resting by design

    Some controllers stop the cellar-side fan between runs, or run it at low speed. Watch it through a full cycle before judging.

    No repair: check it yourself
  2. 02 low to moderate

    Fan motor worn out

    Bearings dry out after years of running, the motor slows and finally stops. A new motor is a routine repair on most units.

    Fixed by cellar evaporator and condenser fan repair
  3. 03 low

    Blade blocked by ice or debris

    Ice on the cellar-side coil can reach the blade, and dust, insulation or a label can wedge the hot-side fan.

    Fixed by cellar coil icing and defrost repair See cellar cooling evaporator coil icing up
  4. 04 low to moderate

    Fan capacitor or controller output failed

    Some fan motors need a small capacitor to start, and all of them need the controller to power them. Either can fail while the motor is sound.

    Fixed by cellar controller and sensor repair

Questions about
cellar cooling unit fan not running.

Should the fan in my cellar unit run all the time?
It depends on the model and its settings. Some run the cellar-side fan constantly to keep air moving, others only when cooling. The manual describes your unit's pattern.
Can I run the cellar unit with one fan stopped?
Not for long. Without the cellar-side fan the coil ices; without the hot-side fan the compressor overheats. Turn it off from a dry panel and keep the door shut until the fan is replaced.
Is replacing a fan motor a big repair on a cellar unit?
On most units, no. The motors are standard parts reached through a panel, though a ceiling unit or a unit deep in a wall takes longer to get at.
Why did the fan squeal for weeks before it stopped?
That squeal is dry bearings. It is the fan's warning, and replacing it then avoids the warm cellar that follows.
