My Gazo GF Clock won't chime on hour at all

Source: Wikipedia

The full hour chime is followed by one strike for the number of the hour by Big Ben (E3) (one strike for one o'clock, two strikes for two o'clock, and so on). ... The mechanism then plays two complete sets of five sequences for each complete hour.

Learn how to fix a mantel clock that chimes at the wrong hour. This simple fix will repair a clock that chimes at the wrong time. This can commonly occur when your mantel clock is laid down on its back and the timing is offset.

1 Thing You Have to Understand First On most clocks you can turn the minute hand counter-clockwise but SOME clocks are not safe to be turned in that direction. For this reason, it's best to only turn your minute hand clockwise just to be safe.

The Simple Mantel Clock Adjustment The easiest way to adjust a mantel clock chime is to move the hour hand to the hour that the chime is striking. Make sure that the hour hand shaft is not too tight or else it will not turn. Most mantel clock hands are friction held. DO NOT BEND YOUR HOUR HAND, loosen the shaft if it will not turn freely.
Once you have synchronized the hour hand with the hourly chime, adjust the minute hand to set the clock to the correct time by moving it forward (clockwise) around the clock face. Allow the chime to strike at every quarter hour strike.
Mantel clock Chime Adjustment When your mantel clock chimes the wrong number of times, your chime is not synchronized time of the clock. To adjust your mantel clock chime, proceed with the following step:

ADJUSTING THE HOURLY CHIME

1. When your mantel clock chimes, count the number of times it chimes. This is what time your hourly striker is set to.
2. Move the hour hand to the hour indicated by the hourly chime (count the number of gongs at the hour).
3. Reset the time using the minute hand to the correct hour and the chime should adjust along with the clock hands as well.

ADJUSTING THE QUARTER CHIME

On most mantel clocks, you can simple remove the minute hand which is friction fit. You have to apply pressure on the tube and it will loosen. Once removed, re-install the minute hand at the correct time. From there you can rotate the minute hand to reset the time.

A worn chime cog wheel will not reset or advance the count. Unless you're good at making gears, you'll need a decent clock repair guy in your area.

It could take an horologist a while to sort out why it suddenly changed. It isn't unusual for a chiming clock to chime at the quarters and half-hour as well as chiming and striking the hour. A quality clock usually allows the manner of chiming/striking to be selected and sometimes even the volume can be altered.

If your clock used to chime and strike the hour and now doesn't and appears to have slipped by exactly 30 minutes clearly something is happening. In the old days such things were often the result of turning the hands backwards to reset the time - that type of clock should be reset only by turning the hands forward and pausing at each quarter, half and hour to allow the chiming of each to complete. Most folk simply stop their clocks and wait for time to catch up...

It is also reckoned such a clock should not be kept next to an exterior wall but rather in a place where the temperature and humidity is the most stable.

I am hoping that you oiled it also? One trick I have found is to gently lift the hammers and release, sometimes the hammers will release and strike the chimes/gong. Do this 4-5 times and hopefully it will get it chiming for you again.

Is this a older type mantel clock or an electric. A older one has a small arm on the back of the wooden case just move it to it's opposite position and that should stop all chimes. A few times that small switch is on the inside but very rear. If it's electric it also should have a switch to turn off all chimes.

Check the wires in the back.some times the get corrodes.

In my eyes there are two kinds, ones that are a real grandfather clock that runs on gravity using a series of weights and gears with different counterweights for chimes and running the clock itself, and there are the show pieces that look like a grandfather clock but run on newer tech and electronics. If a real one then would try first pulling the weights to the top. They are usually shaped into a pinecone or something. If weight is at bottom them have to pull corresponding chain with weight till the weight is at the top of case. As "time" goes by the weights lower. You should have different counterweights for the clock, chimes, dancing figures and whatever else it may have. All the weights move at different "speeds" so you have to keep an eye on them to make sure it keeps correct time. I would recommend consulting the manufacturer if possible. There are so many kinds out there is really hard to tell by such a short video.

In a quartz movement clock, with a problem like this, the chime box (or whole movement) will need to be replaced. Timesavers.con carries a large selection of chiming quarts movements.

The next time it chimes multiple times turn the hour hand clockwise until it is pointing at the number of times it gonged. Next take off the dial nut off (make sure to put it in a plastic bag because they can be hard to replace) and turn the minute hand until it chimes signaling 15 minutes after. Now put the minute hand back on pointing to 3 o'clock and replace your dial nut and you are all set.
