Maintenance

Beyond beer lines: faucets, drip trays, refrigeration troubleshooting.

Kegerator maintenance is mostly about preventing the things that go wrong from going wrong. Clean the faucet every 4-6 weeks. Clean the drip tray weekly. Check the fridge thermostat seasonally. Inspect the gas line annually for cracks. Replace the o-rings when they harden.

Most failures we see in the home-kegerator field aren't catastrophic — they're slow degradation that you only notice when the pour quality drops or the unit starts losing temperature. A 30-minute maintenance session every 4-6 weeks prevents 80% of the problems people post about online.

Below: every maintenance walkthrough we've written, from faucet disassembly to thermostat calibration to the seasonal checks worth doing.

Frequently asked: maintenance

How do I clean a kegerator faucet?

Disassemble the faucet (faucet wrench unscrews the front bonnet). Remove the spout, the diffuser, and the lever assembly. Soak all parts in beer-line cleaner solution for 15 minutes. Scrub with a faucet brush. Rinse thoroughly in clean water. Reassemble. Do this every 4-6 weeks for daily-use faucets, every 8-12 weeks for occasional-use.

What should I clean inside my kegerator fridge?

Drip tray (weekly — beer drips and dries into a sticky mess). Fridge floor (monthly — same reason). Door seal (quarterly — debris in the seal causes temperature drift). The interior walls don't need regular cleaning unless something's leaked. Don't use bleach or strong solvents inside the fridge; food-safe surface cleaner is fine.

How do I fix a kegerator that won't stay cold?

Three usual causes. (1) Door seal is dirty or damaged — beer dust gets in the seal channel; clean and re-seat. (2) Thermostat is miscalibrated or failing — test with an external thermometer; calibrate or replace. (3) Compressor is failing — uncommon in units under 5 years old; common in units over 10 years. Replace compressor or replace unit; the math usually says replace unit on budget kegerators.

When should I replace beer line tubing?

Annually for daily-use lines, every 18-24 months for occasional-use. Tubing degrades from beer's mild acidity and from line-cleaning chemicals over time. Symptoms of old tubing: cloudiness, hardness, or visible scoring on the inside. Replacement is cheap ($5-$15 for 25 feet); do it before you have a problem.

How often should I check my kegerator's CO2 system for leaks?

Soap-test the regulator and connections every time you swap a CO2 tank (which happens every 6-12 months). Quick visual check — gauges, connections, hoses — monthly. If CO2 consumption seems to be rising, do a full soap-test immediately. A slow leak costs you $20-$40 of CO2 per year; a fast leak costs you a keg of beer.
