Steps

Goal: Confirm the symptom, check CO2 pressure, keg coupler, faucet, and beer line.

  • Confirm the kegerator is cold (beer 36–40°F) and nothing comes out when you open the faucet.
  • Good: The unit cools but no beer pours—draft fault. Proceed to Check CO2 and coupler.
  • Bad: The unit does not cool—different problem. See When to get help.

Check CO2 and coupler

Goal: Rule out CO2 pressure and keg connection before checking the faucet and line.

  • Check the CO2 pressure gauge on the regulator. Serving pressure for most beers is 10–14 psi. If the gauge reads zero or very low, the tank may be empty. Confirm the tank valve is open.
  • If the tank is empty, replace or refill it. If the regulator does not hold pressure when the valve is open, call a pro.
  • Confirm the keg coupler is fully seated. Push down firmly and twist until it locks. You should hear a hiss when gas enters the keg. Check that the keg is not empty—lift it; an empty keg feels light.
  • Good: CO2 pressure is 10–14 psi and the coupler is locked. Proceed to Faucet and line.
  • Bad: Gauge at zero, tank empty, or coupler loose—fix those first.

Faucet and line

Goal: Check the faucet and beer line for blockages.

  • Confirm the faucet handle is fully open. If it is stuck or only drips, remove the faucet, disassemble, and clean with warm water and a brush. Replace if corroded or the handle will not move.
  • Inspect the beer line from the coupler to the faucet. Look for kinks, pinches, or frozen sections. Straighten kinks. If the line is frozen, raise the temperature setting slightly (36–40°F) and wait an hour.
  • If the line is old or has buildup, replace it. Typical line length is 5–8 feet for a balanced pour.
  • Good: Faucet opens freely and the line is clear. Beer should pour.
  • Bad: Faucet stuck or line blocked—clean or replace and retest.

Foam and cleaning

Goal: Address excessive foam or dirty system.

  • If foam blocks the line, lower CO2 pressure to 10–12 psi and let the keg settle for a few hours. Confirm the beer is cold.
  • If the faucet and line are dirty, run a cleaning solution through the system, then flush with water. Replace the line if it is discolored or has a strong odor.
  • Good: Foam clears or system is clean. Beer pours with minimal foam.
  • Bad: Still no pour after all checks—call a pro.

When to get help

Call an appliance or draft-system technician if:

  • The CO2 regulator does not hold pressure.
  • The keg coupler seal is damaged and you cannot replace it.
  • You have checked CO2, coupler, faucet, and line and it still does not pour.

Verification

  • Beer pours when the faucet is opened, with minimal foam.
  • CO2 pressure reads 10–14 psi on the gauge.
  • The keg coupler is locked and the beer line is free of kinks and blockages.
  • The faucet opens and closes smoothly.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Confirm symptom Verify the kegerator cools but nothing pours; rule out a cooling problem.
  2. CO2 pressure and coupler Check CO2 gauge, tank valve, and that the keg coupler is seated.
  3. Faucet and line Check the faucet is open, and the line for kinks, clogs, or freeze.
  4. Foam and cleaning Adjust pressure for foam; clean faucet and line if dirty.
  5. Call a pro Regulator failure, damaged coupler seal, or all checks done and still no pour—call a technician.

What to capture if you need help

Before calling support or posting for help, have these ready. It speeds everything up.

  • CO2 pressure reading
  • Whether the keg coupler is seated
  • Faucet condition (stuck or dirty)
  • Beer line condition (kinked, frozen, or clogged)
  • Steps already tried

Does the kegerator cool but nothing pours when you open the faucet?

Confirm the interior is cold and no beer flows when you open the faucet. If the unit does not cool, that is a different problem.

Confirm the kegerator is cold (beer 36–40°F) and nothing comes out when you open the faucet. Good: cools but no pour—draft fault. Bad: does not cool—different problem; check cooling first.

Is CO2 pressure 10–14 psi and the keg coupler seated?

CO2 pressure and coupler connection are the most common causes of no pour.

Check the CO2 pressure gauge—should read 10–14 psi with the tank valve open. Confirm the keg coupler is pushed down and twisted until locked. Good: pressure OK and coupler seated. Bad: gauge at zero or coupler loose—fix those first.

Yes No

You can change your answer later.

Fix CO2 or coupler and test

If tank empty: replace or refill. If pressure low: open tank valve, adjust regulator to 10–14 psi. If coupler loose: push down firmly and twist until locked. Retest pour. If regulator does not hold pressure, call a pro.

Done

Is the faucet open and the beer line free of kinks or freeze?

Faucet stuck or line blocked prevents pour.

Confirm the faucet handle pulls forward fully. Inspect the beer line for kinks, clogs, or frozen sections. Straighten kinks; thaw frozen line by raising temp slightly. Good: faucet open and line clear. Bad: faucet stuck or line blocked—fix and retest.

Yes No

Fix faucet or line and test

Clean or replace the faucet if stuck. Replace the beer line if kinked or clogged. Retest pour. If foam blocks flow, lower pressure to 10–12 psi and let the keg settle.

Done

Is foam blocking the line or is the system dirty?

Excessive foam or dirty line can prevent pour.

If foam blocks flow: lower CO2 to 10–12 psi, confirm beer is cold, let keg settle. If faucet or line is dirty: clean with a draft cleaning kit. Good: foam cleared or system clean—beer should pour. Bad: still no pour—call a pro.

Frequently asked questions

Why would a kegerator cool but not pour?
Common causes: CO2 tank empty or pressure too low, keg coupler not seated, faucet stuck or closed, beer line kinked or frozen, or a clog in the line. Check CO2 pressure and the coupler first.
Can I fix a kegerator that will not pour myself?
Yes, for most causes. You can adjust CO2 pressure, reseat the coupler, clean or replace the faucet, and clear or replace the beer line. Regulator or sealed-system issues may need a pro.
When should I call a technician for a kegerator that will not pour?
Call a pro if the CO2 regulator does not hold pressure, the keg coupler seal is damaged and you cannot replace it, or you have checked all components and it still does not pour.
