Common Clock Problems and Their Simple Fixes
Clocks are remarkably durable machines, but like any mechanical or electronic device, they occasionally develop issues. The good news is that many common clock problems are caused by setup, environment, or minor alignment issues rather than serious mechanical failure. With a basic understanding of how clocks operate, owners can often correct these problems safely at home. This guide outlines the most frequent clock issues encountered with both mechanical and quartz clocks—and explains simple, effective solutions.
Problem 1 — Clock Stops Randomly
Random stopping is one of the most common complaints, especially with pendulum clocks.
Likely causes include:
Clock out of beat
Improper leveling
Weak or damaged suspension spring
Insufficient power due to friction
Simple fixes:
Re-level the clock side-to-side
Listen for an even tick–tock rhythm and adjust beat
Inspect the suspension spring for bends or cracks
If the clock still stops after correction, internal friction may be the cause.
Problem 2 — Clock Runs Fast or Slow
Inaccurate timekeeping can usually be corrected with small adjustments.
Mechanical clocks:
Adjust pendulum length
Raise bob → speeds up
Lower bob → slows down
Keep the clock in a temperature-stable environment
Quartz clocks:
Replace batteries with fresh, high-quality alkalines
Reset the movement completely
Use the internal +/– regulator if present
Always make small changes and evaluate accuracy over 24 hours.
Problem 3 — Chimes Out of Sequence
Chimes that play at the wrong time or strike the wrong count are usually out of sync—not broken.
Common fixes:
Move the minute hand forward only
Allow all chime and strike sequences to complete
Let the clock run through a full hour for auto-correction
Reposition the hour hand if the strike count is correct but the dial is wrong
Chime issues often occur after the clock has been stopped or moved.
Problem 4 — Hands Rubbing or Getting Stuck
Hand interference can cause stopping, missed chimes, or erratic timekeeping.
Fixes include:
Gently re-bend hands so they sit parallel
Ensure hands do not touch each other, the dial, or the glass
Tighten the minute-hand bushing so it sits firmly
Even slight contact between hands can disrupt clock operation.
Problem 5 — Quartz Clock Won’t Run
If a quartz clock fails to start, the issue is usually electrical rather than mechanical.
Troubleshooting steps:
Replace the battery
Clean battery contacts with a dry cotton swab
Check for corrosion or leakage
Replace the movement if the motor is silent or erratic
Quartz movements are typically replaced rather than repaired.
Problem 6 — Weak Pendulum Swing
A pendulum with low amplitude cannot regulate time properly.
Possible causes:
Dirty or dry pivots
Incorrect beat alignment
Bent pendulum leader
Excessive friction in the movement
Solutions:
Correct beat and leveling
Reduce environmental vibration
Schedule professional cleaning if the movement hasn’t been serviced in years
Weak swing is often an early sign of internal wear.
When to Call a Professional
If a problem:
Repeats frequently
Worsens over time
Cannot be corrected with basic adjustments
Involves grinding, binding, or locking mechanisms
…the clock likely needs professional service such as cleaning, bushing work, or movement replacement.
