Keurig K-Brew + Chill Iced Coffee Not Getting Cold? 5 Fixes

How the K-Brew+Chill Makes Coffee Cold

A K-Brew+Chill that brews warm on COLD almost always has a Chill Tank that isn't fully charged. Both Cold Charging Bar LEDs should be solid before you brew. That takes up to 6 hours from empty, and a full charge covers only four cold brews, each a little warmer. A low tank or blocked airflow cause most other cases.

There's no compressor, no refrigerant and no "pre-chill" button. Every pod is brewed hot. On COLD, the hot coffee then runs through aluminum coils inside the Chill Tank, a chamber of about 11.5 cups of water cooled by a thermoelectric module. The cold stored in that water pulls the heat out, and Keurig says the coffee reaches the cup below 60°F in 3 minutes or less. The fan pushes the heat out of the machine.

That design explains every fix below. The tank needs water, time to store cold, and room to get rid of heat. Brewing uses up the stored cold, and it takes hours to rebuild. Everything here comes from Keurig's K-Brew+Chill Use & Care Guide unless we say otherwise.

What "Cold" Should Look Like

Before troubleshooting, check whether the machine is actually underperforming.

• Keurig's claim: below 60°F, "as cold as" a coffee-shop iced coffee, with no ice in the cup.
• In one published hands-on review: about 54°F for the first cold cup on a full charge, and 68.5°F for a second cup brewed right after. So a warmer second cup is normal, not a fault.
• Consumer Reports found it "maintained temperatures somewhat inconsistently from cup to cup."

To test, brew 6oz on COLD into an empty glass with both Charging Bar LEDs solid. Check it with a kitchen thermometer, or compare it to water from the fridge. Cool but not fridge-cold is within spec. If it comes out as hot as a normal HOT brew, go straight to Fix 3 and then When It's a Cooling Fault.

Quick Checks

• Press COLD while the brewer is idle. That shows the charge on the Cold Charging Bar. Solid is fully charged, blinking is charging, and dark means chilling is off.
• Is COLD lit before you press the K button? The brewer defaults to HOT every time.
• Is the CHILL TANK light off? If it's lit, the tank is below Max Fill.
• Is the brewer 6 inches from walls and cabinets, and away from the stove?
• How many cold brews since it last charged? More than four means the stored cold is used up.

Fix 1: Let the Chill Tank Fully Charge (Works About 50% of the Time)

Cold coffee needs a charged tank, and charging is slow. Keurig says a full charge from warm takes up to 6 hours in High Performance mode, and more than 7 hours in Quiet mode. One full charge covers four cold brews in a row. Each brew takes some of the stored cold, so each one comes out slightly warmer.

Signs it's this one: a brand-new machine, one that was just refilled or switched back on, or cold cups that got warmer as the day went on.

1. Press COLD while the brewer is idle and look at the two Charging Bar LEDs.
2. If they're blinking, leave the brewer plugged in and wait. Fast blinking means High Performance mode and slow blinking means Quiet mode.
3. Brew cold only once both LEDs are solid. You can brew earlier, but the manual says it won't be as cold.
4. For a household that drinks several cold coffees a day, brew them spread out rather than back to back. The time to get back to solid depends on how many cold brews you just made. It can take up to 6 hours after heavy use.
5. New machine: plan for the first cold cup the next morning. Filling the tank at night lets it charge fully overnight.

Time: Up to 6 hours (hands-off)
Cost: Free
Success Rate: About 50%
Difficulty: Easy

Keep the brewer plugged in. The brewer shuts off 5 minutes after the last brew, but the Chill Tank keeps charging. Unplugging it at night, or using a smart plug on a timer, throws the charge away.

Fix 2: Fill the Chill Tank to the Max Fill Tab (Works About 20% of the Time)

The Chill Tank holds about 11.5 cups of water, and that water is where the cold is stored. Water slowly evaporates from it, so a tank that was full at setup won't stay full forever. The CHILL TANK light comes on when it needs topping up. That's usually about once a year, or straight away if the tank was emptied to move the brewer.

Signs it's this one: the CHILL TANK light is on, or the machine was recently moved or stored.

1. Remove the Chill Tank lid and find the opening with the Max Fill tab.
2. Pour cool tap water in slowly until it reaches the Max Fill tab and the CHILL TANK light goes out. A pitcher with a spout is easiest. It takes about one and a half reservoirs of water.
3. Use the coldest tap water you have. Keurig says colder water charges faster.
4. Listen for the fan. It starts once there's enough water in the tank.
5. Put the lid back on and press it down firmly.
6. Then give it the charging time from Fix 1.

Don't overfill past the tab. Stop when the light goes out and the water reaches Max Fill. Water above the tab has nowhere to go when you press the lid back down. Our K-Brew+Chill leaking guide covers that.

Fix 3: Turn Chilling Back On (Works About 15% of the Time)

The QUIET button controls the cooling system, and it's easy to switch cooling off without realizing. One press moves from High Performance to Quiet. A second press turns chilling Off. Pressing and holding QUIET pauses chilling for 6 hours. Hot brewing works normally in all of these, so nothing looks wrong until a cold cup comes out warm.

Signs it's this one: the Charging Bar is dark when you press COLD, or someone turned the fan down because of the noise.

1. Press COLD while the brewer is idle. If the Charging Bar LEDs are dark, chilling is Off or paused.
2. Press QUIET to cycle through the modes until the Charging Bar lights up again. High Performance charges fastest.
3. If both Charging Bar lights and COLD were flashing after a long press, that was the 6-hour pause. Chilling restarts by itself once the pause ends.
4. Starting a Cold brew while chilling is Off also turns it back on. That cup will still be warm, because the tank needs up to 6 hours to recharge.
5. Quiet mode is fine for temperature. Keurig says it reaches the same cold temperature as High Performance, but it takes longer to charge and to recover between brews.

Fix 4: Give the Brewer Room to Shed Heat (Works About 10% of the Time)

The cooling system moves heat out of the Chill Tank, and the fan and vents blow it into your kitchen. If that warm air can't get away, or the brewer sits next to a heat source, the tank charges slowly and never gets as cold. Keurig's placement rules exist for this reason.

Signs it's this one: a solid Charging Bar but only mildly cool coffee, a fan that seems to run constantly at high speed, or warm air building up around the brewer.

1. Pull the brewer out so it has at least 6 inches of clearance from walls, backsplashes and cabinets. That's Keurig's guidance for best cooling.
2. Move it away from stovetops, ovens, toasters, dishwasher vents and other heat sources.
3. Keep it out of direct sunlight. A sunny counter can make the housing much warmer than the room.
4. Don't store anything on or against the brewer, like mugs, pod drawers or tea towels.
5. Wipe dust off the vent openings with a dry cloth. This is our own addition, not in the manual. Don't spray cleaner into the vents, since the manual only calls for a damp cloth on the outside.
6. After moving it, give the tank another full charging cycle before you judge the temperature.

Time: 10 minutes, plus charging
Cost: Free
Success Rate: About 10%
Difficulty: Easy

A very warm kitchen in summer slows charging too. It doesn't mean the brewer is faulty, but it does mean you get fewer cold cups per charge.

Fix 5: Brew Cold the Way the Machine Expects (Works About 5% of the Time)

A few habits make coffee from a healthy K-Brew+Chill taste warm or watery. They come from treating it like a Brew Over Ice Keurig.

Signs it's this one: the cup is diluted and tepid rather than cold, or the result varies with how you brew.

1. Select COLD before every brew. The brewer defaults to HOT. Choose COLD, then the size, then press the K button.
2. Brew into an empty cup, not onto ice. Keurig's manual says not to brew over ice into a glass. Add ice after the brew, which also leaves room for milk.
3. Let the Cold Auto Rinse finish. After each cold brew, RINSE blinks for about a minute while the brewer runs an automatic rinse. Keurig says the rinse keeps QuickChill "running at top performance," so don't open the handle until the blinking stops.
4. Start with a room-temperature or chilled cup. A mug straight out of the dishwasher warms the coffee. This is our own tip, not in the manual.
5. Use STRONG if cold coffee tastes thin. Chilled coffee tastes less intense than hot. STRONG works on COLD too. Weak flavor is a strength issue, not a temperature fault, and our Keurig weak coffee guide covers it.

When It's a Cooling Fault

The cooling system has no parts you can service, and Keurig says the brewer isn't user-serviceable beyond cleaning and descaling. Call Keurig at 1-866-901-BREW (2739) if any of these happen after Fixes 1-4:

• The CHILL TANK light stays on with the tank filled to the Max Fill tab
• The Charging Bar never goes solid after 6+ hours in High Performance mode, with the brewer placed as in Fix 4
• The fan never starts after you fill the tank
• COLD brews come out as hot as HOT brews, even with a solid Charging Bar

The K-Brew+Chill has a limited one-year warranty in the US and Canada. You need proof of purchase, and Keurig must issue a Return Materials Authorization (RMA) number before you send the brewer back. Keurig may replace it with a new or reconditioned brewer.

If it brews cold but has other problems, like not pumping, partial cups, no power or a DESCALE light, see our K-Brew+Chill not working guide.

Keeping It Cold Long-Term

• Leave the brewer plugged in, so the Chill Tank keeps its charge between uses
• Top up the Chill Tank whenever the CHILL TANK light comes on
• Keep 6 inches of clearance, and keep the brewer away from heat and sun year-round
• Keep to four or fewer cold brews in a row
• Empty the Chill Tank before storing or moving the brewer, then refill it and allow a full charge
• Descale every 3 months, or when DESCALE lights. Scale slows the brewing side, and a descaling procedure is in the not working guide

FAQ

Why is my second K-Brew+Chill cold coffee warmer than the first?

Each cold brew uses up some of the cold stored in the Chill Tank. A full charge covers four cold brews, and Keurig says each one comes out slightly warmer. In one hands-on test, the first cup was about 54°F and one brewed right after it was 68.5°F. Waiting between brews lets the tank recover.

Can I put ice or ice-cold water in the Chill Tank to speed it up?

Keurig only says to fill the tank with cool tap water, and that colder water charges faster. The manual doesn't mention ice. Cold tap water or water from a fridge pitcher gets you the benefit without risking an overfill as ice melts.

Does Quiet mode make the coffee less cold?

No. Keurig says Quiet mode reaches the same cold temperature as High Performance mode. It just takes longer, 7+ hours for a full charge, and recovers more slowly between brews. If you only drink one cold coffee a day, Quiet mode costs you nothing.

Is the fan supposed to run when the brewer is off?

Yes. The brewer turns itself off 5 minutes after the last brew, but the Chill Tank keeps charging and the fan keeps running. To stop it, press QUIET twice to turn chilling Off, or hold QUIET to pause it for 6 hours. Either way, your next cold coffee will be warm until the tank recharges.

Do pods matter for cold coffee?

Any K-Cup pod works on COLD, and the temperature doesn't change with the pod. Flavored coffee, tea, cocoa, Refreshers and One-Step Lattes can leave flavors behind, so Keurig recommends a Rinse after them.
