A simple clock issue can confuse owners as it being broken. For example, the mechanism of a grandfather clock can be damaged during the moving process, or some adjustments are needed if the clock is placed on uneven floor.

Premier Clocks has collected the most common issues that a grandfather clock can have and how to troubleshoot them. There will be some clock related terminology, please check out blog post about The Terminology and Parts Of A Grandfather Clock.
There are several reasons why the pendulum stopped swinging. If you are not familiar with what a pendulum is, you can read about it here.
When the pendulum works correctly, it should make an even "tick-tock" beat sound. If you hear that the space between "tick" and "tock" is not even, it means that the clock is out of beat. Check the video below about how to adjust the pendulum of Howard Miller grandfather clocks.
One of the problems can be related to a weighted hammer. You need to check if it is positioned properly. Make sure that an upper part of the body is in the center and if it is not, adjust it with your hand. The pendulum should be swinging freely without touching the chime rods or weights. Here is the detailed guide on How to Hang a Grandfather Clock Pendulum.
If the pendulum touches the weights or chime rods, it stops working. It means that there is an issue with leveling. The clock has to be adjusted from front to back or side to side. Howard Miller grandfather clocks have 4 adjustable levelers on the bottom corners making the adjustment an easy process.
Each weight has a different task and it is crucial that they are placed correctly. There is a guide on Grandfather Clock Weight Functions and Placement. A common issue with the weights is that they are not positioned in correct places.
Usually, the weights should be marked with L (left), C (center) or R (right) on the bottom with where it should be positioned. Note that you should be facing the grandfather clock when determine left, center and right.
If there are no marks, you can hang the weights depending on how heavy they are. When facing the grandfather clock, the heaviest weight should be on the right, the second heaviest - in the middle, and the least heavy goes on the left.
Another issue that might arise is that the weights do not drop at the same level. However, when the automatic nighttime shutoff feature is selected, and on some models the “silent” feature, it is normal that the center weight will drop at a faster rate than the other weights.
To avoid some of the issues, the weights must be raised every week to ensure that the clock continues running and keeping time. Check How to Wind a Grandfather Clock for detailed instructions.
One of the most popular question from the grandfather clock owners is about why a grandfather clock does not chime at proper time.

If the grandfather clock chimes more than one minute before or after the proper time, the minute hand should be removed and adjusted. Below are the instructions but when performing this operation be careful not to scratch the hand nut, hand or dial.
1. When the grandfather clock starts to chime, stop the pendulum and record the time.
2. Using pliers, carefully remove the small nut that holds the minute hand in place by turning the nut counterclockwise while at the same time hold the minute hand with your fingers near the small nut.
3. Remove the hand from the hand shaft by grasping it with your fingers at the point where it attaches to the shaft. Pull the hand straight off. This hand is not screwed on and should come off easily. The minute hand has a small raised area on the back side directly around the shaft hole, this is the hand bushing. Using pliers, grip the bushing firmly by its sides so that it cannot slip in the pliers. With your other hand, turn the clock hand forward or backward the distance necessary to chime at the correct time.
4. Re-attach the hand to the shaft and turn the hand nut finger tight. Make sure the hand points to the correct location that you recorded in Step 1 plus any corrections you made in step 3. If the hand does not point to the correct mark, repeat steps 2 and 3.
5. Snug up the hand nut with the pliers. Do not over tighten.
6. Start pendulum.
7. Re-set the time by moving only the minute hand counterclockwise (backwards) as described here.
EXAMPLE: Grandfather clock chimes at 1:10 but should chime at 1:15.
Step 7: Reset grandfather clock to current time.
If your clock does not strike the correct hour, grasp the hour hand only and move it forward or backward to line up with the correct hour on the dial indicated by the number of times the hour strikes. Rotating this hand independently will not damage the clock. If the minute hand needs to be reset (to correct time), move the minute hand counterclockwise (backwards) as described here.
What to do if a grandfather clock will not chime or strike. Make sure that the selection lever is not in the “silent” position or halfway between two chime melody positions. Make sure that all the packing material is removed from the movement area. Make sure that the weights are hanging in the correct location by checking the label on the bottom of each weight to ensure proper location. For models with nighttime silencing, make sure that the grandfather clock isn't in the nighttime silence mode. Check hammer adjustment and correct chime tone as necessary.
Move the chime selection lever to a different melody or to “silent”. It is possible that the styrofoam blocks located above the cable pulleys are binding the cable. Carefully remove the styrofoam blocks by lifting the blocks straight up until they clear the cable pulley. Then gently push them back through the cables. Don't use tools to remove the blocks. Don't permit the cable to overlap on the drum.
Examine the dial on the grandfather clock and look at the hour and minute hands to make sure they do not touch or hang on any part of the dial (for example, each other, the dial or the glass pane, etc.). If they touch any part of the dial, you need carefully readjust one or both hands to create enough clearance between the parts.
First, try to move the hour hand in the opposite direction of the object they touch. In case it is impossible to fix with readjusting only an hour hand, you can move the minute hand too. The most important thing to remember is that you need to be extremely careful and avoid touching the dial during this process.
The dial is probably the most mysterious part of a grandfather clock and it raises many questions.
If there is a difficulty to rotate the moon dial of your grandfather clock, this can be an indication that the gears which automatically advance the moon dial are engaged. To correct this situation, rotate the minute hand backward 3-1/2 hours as described here, set the moon dial, and then reset the time. In case this does not help, follow the instructions below.
Face the clock and remove the top side panel. Open the door on the side or remove the panel from the back access section. Look inside at the back side of the dial to locate the click spring. Place your pointer finger on the tip of the click spring. Pull the spring 1/2-inch back, and then quickly release it. Watch to see if the click spring and saw tooth moon dial snap into alignment. Never force the moon dial if it doesn’t work after this adjustment. Rotate the minute hand backward 3 hours.
Despite the common opinion that grandfather clocks are fragile, they in fact are quite durable pieces. And some of the problems can be easily fixed. But if you try to fix an issue and it does not seem to work, we recommend to call a professional clockmaster to repair your grandfather clock.
