Viking Ice Maker Not Working
A Viking ice maker only works with power, water at decent pressure and a freezer cold enough to freeze the mold through. Take one away and it simply stops, so most dead ice makers turn out to be an arm left up, a warm freezer or a starved water line before they are a failed part.
$79 service call, applied to the repair. Monday to Saturday, 8 AM to 7 PM.
In short: push the wire arm down, check that the freezer is at 0 to 2°F, open the water supply fully and look for a kinked line or an old saddle valve. A reverse osmosis system often starves it. Then give it a day: a healthy unit makes seven to nine batches in 24 hours. Small or hollow cubes point at the water supply, not the ice maker.
How a Viking ice maker is supposed to work
The 5 Series side-by-sides and the bottom-mount use the same ice maker design. Each cycle it fills its mold with a few ounces of water, waits until the cubes are frozen solid, warms the mold just enough to free them, pushes them into the bucket and refills. A colder freezer and open space around the ice maker make each batch come sooner.
A wire arm rests on top of the ice. When the bucket is full, the ice holds the arm up and production stops; raising the arm by hand until it clicks turns the ice maker off. Opening the freezer door also cuts its power, so a busy freezer makes less ice.
Owner checks before you call
- Push the arm down. Viking asks you to raise it before Sabbath mode and lower it afterward, and the second step is easy to forget. A bag of food or a crooked bucket can also hold it up.
- Check the freezer temperature. A thermometer pressed between frozen packages for five to eight hours should read 0 to 2°F. Much warmer, and the freezer is the real problem; see Viking refrigerator not cooling. Before a party, MAX FRZ holds the freezer at its coldest for four hours.
- Open the water supply fully. The shutoff is usually under the sink or in the next cabinet. If the refrigerator was recently pushed back into its opening, the line behind it may be kinked.
- Look at what feeds it. Viking warns against reverse osmosis systems, which drop the pressure below what the valve needs to fill the mold. The valve needs normal household water pressure, and dispenser models need more than models without a dispenser, so a weak supply shows up on them first. Old pierce-type saddle valves clog with minerals and are a common cause of slow filling.
- Check the filter on side-by-sides. It sits behind a press-to-open door at the bottom center of the refrigerator section. On dispenser models both the ice and the water pass through it, so an overdue filter slows both.
- Make sure the freezer door closes fully. A door or drawer that rests slightly open keeps the ice maker switched off, and lets in warm, humid air.
- Break up any clump. Ice that has melted and refrozen into one block can hold the arm up or jam the dispenser. Empty the bucket, let it warm, and start fresh.
What the ice tells you
| What you see | What it usually means | What to do |
|---|---|---|
| No ice at all, arm down, freezer cold | No water reaching the mold, a frozen fill tube, or no power to the ice maker | Check the supply valve and line, then call. |
| Small, thin or hollow cubes | Too little water per fill: weak pressure, a restricted line or valve screen, or a unit out of level | Check the supply and any filter; call if it persists. |
| Cubes stuck to the ice maker, or landing outside the bucket | Usually a short fill that leaves thin cubes, or a part of the ice maker knocked out of position | Check the water supply first; call if it keeps happening. |
| Water spilling over, or a sheet of ice in the bucket | A valve not closing fully, pressure too high, or the unit not level | Close the supply valve and call. |
| White crust in the mold, cubes that stick | Hard water leaving mineral scale | A filter helps; the mold may need cleaning or replacement. |
| Water dispenses but no ice (D models) | The supply and the filter are fine; the ice side of the valve set, a frozen fill tube or the ice maker | Call; the supply is not the problem. |
What it usually turns out to be
Weak or interrupted water supply
What it usually is: a clogged saddle valve, a kinked or crushed line, a shutoff left half open, or a filtration system that drops the pressure. The ice maker still cycles, so the bucket fills with slivers or nothing.
What you can check: the shutoff, the line you can see, and when the filter was last changed.
What we do: measure flow and pressure at the unit and, if the supply is the cause, tell you before anything is replaced. An old saddle valve is best swapped for a proper shutoff.
Water valve
What it usually is: grit and hard-water scale can block a valve, so the mold fills short, or stop it closing fully, so it drips between fills. Units without a dispenser use a single valve behind the kickplate. Dispenser models run the water through two valves in a row, so a valve stuck open cannot flood the kitchen. Dispenser models built after mid-May 2010 use a revised valve set, so we order valve parts by serial.
What you can check: water under the kickplate, or a fill you can hear running too long.
What we do: test each valve and its controls, measure a timed fill, and set the fill amount after replacing a valve.
Frozen fill tube
What it usually is: a valve that weeps between fills, or a slow dribble from low pressure, freezes in the tube where water enters the freezer. The ice maker keeps turning but no water arrives.
What you can check: ice in the cup behind the mold where the water enters. Do not chip at it with anything sharp.
What we do: thaw the tube, then fix why it froze, usually the valve or the supply.
The ice maker itself
What it usually is: a failed part inside the ice maker: the sensor that tells it the cubes are frozen, the small heater that frees them, the motor, or an overheat cutoff. A broken or bent arm also stops it.
What you can check: whether the blades have parked in the same spot for a day with frozen cubes in the mold.
What we do: run the ice maker through a test cycle and check each part. Most failures mean replacing the ice maker as one assembly. The swap itself is short; if the part is not on the van, we tell you the lead time before you decide.
Ice made but not dispensed (D models)
What it usually is: the lock switch on, clumped ice, a failed auger motor, a paddle switch, or the ice door motor that should open the chute and hold it open a few seconds after you let go.
What you can check: the lock switch, and the bucket for a solid block.
What we do: test the switches, auger and ice door. Our job write-up Thermador Refrigerator Ice Dispenser Not Working (Irvine, September 2026) shows a similar dispenser repair on another brand.
Where things are on your model
On the 5 Series side-by-sides, the ice maker sits in the freezer above the bucket, with the auger motor behind the bucket on dispenser models. On the 36-inch bottom-mount it is behind a cover in the freezer, and its valve is behind the kickplate on the left. Either way it comes out without moving the refrigerator. Alarms are covered in Viking refrigerator error codes.
Before you reach in. Keep fingers away from the ejector blades and the dispenser chute. If water is spilling, close the supply valve first. Never use a hair dryer or a knife on the ice maker: heat warps the plastic and a blade can gouge the mold.
What an ice maker repair costs
On an ice maker call the written price usually covers a water valve or the ice maker assembly, and the $79 visit is applied once you approve it.

Viking ice maker not working: questions
Why did my Viking ice maker stop after Sabbath mode?
The wire arm has to be raised before Sabbath mode and pushed back down afterward. If it is still up, the ice maker is off; lower it and give it a few hours.
How much ice should a Viking built-in make?
Seven to nine batches in 24 hours when the freezer is near 0°F and the door stays mostly shut. An empty bucket takes most of a day to fill.
Can I connect my Viking to a reverse osmosis system?
Viking advises against it. Most systems drop the pressure too low for the valve to fill the mold, which gives hollow cubes or no ice.
Why are my Viking ice cubes small or hollow?
The mold is not getting enough water each fill, usually from low pressure, a clogged saddle valve, an old filter or a valve screen full of sediment.
My Viking dispenses water but no ice. What is wrong?
The supply and the filter are fine, so the fault is the ice side of the valve set (on dispenser models built after mid-May 2010, including its relay), a frozen fill tube or the ice maker. If ice is in the bucket, look at the lock switch and the auger.
How long after installation does a Viking make ice?
Allow 24 to 48 hours. Throw away the first three bucketfuls, and the first one after the unit sits unused for a long time.
Can the ice maker be repaired, or does it need replacing?
Valves, fill tubes and switches are repaired separately. When the ice maker itself fails, it is usually replaced as one assembly.
