If necessary, de-solder the power cord leads from the field coil terminals to remove the cord.Remove the screws from the case and slide the motor and gears out.Carefully pry off the face cover with a knife blade.Unplug the clock from the electrical outlet.What Are the Steps to Electric Clock Repair? Disassemble an electric clock: The tools you’ll need to fix an electric clock include these: In addition, you can find digital clock units at larger craft stores. You can find replacement parts from the manufacturer or through aftermarket suppliers. What Do I Need for Electric Clock Repair?ĭigital electric clocks are made primarily of circuit boards that can’t be repaired by the typical consumer. Apply a drop of light oil at the point where the motor shaft exits the housing.Īlways remember to unplug the clock before disassembling and working on it. Secure a rattling crystal with a drop of clear silicone adhesive. If the clock is noisy, check for loose parts or a dry shaft.Check the gears for wear replace the clock if the gears are damaged or worn beyond use. Also, use a multimeter to test the field coil inside the clock. If the clock still does not run or keeps time poorly, disassemble the clock (see below) and remove any dirt or lint obstructing the motor or gears.If the clock does not run, make sure that the power is on at the outlet and test the electrical cord.If the hands work loose, use pliers to squeeze the hands tighter to the central shaft.If you’re late for work, maybe you can blame–and fix–the clock. How Can I Identify an Electric Clock Problem? But before tossing the entire clock, check a local craft or electronic shop for a replacement digital clock mechanism. With an inexpensive clock, it may not be worth your time to attempt repair. On digital clocks, the cord or battery may not deliver power to the motor. So why won’t your electric clock work? On analog clocks, hands can work loose, gear teeth can wear down or break, the clock may not run at all or may keep time poorly, or the clock can be noisy. What Can Go Wrong with an Electric Clock? If a component fails, however, the clock will probably have to be replaced because most are difficult to repair. At the preset time, the cam gear moves outward, allowing the vibrator arm to repeatedly contact, or buzz, the frame.ĭigital clocks rely on electronic circuitry instead of gears and levers. When an alarm is set on an analog clock, a cam gear presses against a lever, which in turn holds a vibrator arm above a frame.
Older clocks may have metal gears, but the gears of new clocks are generally made of plastic to reduce operating noise–and manufacturing costs. Electric clocks rely on the 60-cycle-per-second alternations of household current (AC) to ensure accurate timekeeping.Ī synchronous motor inside an analog clock drives a gear train, which in turn moves the clock’s hands. How Does an Electric Clock Work?Ī clock is an instrument for measuring time. This Fix-It Guide also refers to electrical cord repair and motor repair for specific problems.
Sharp alarm clock broken how to#
It then gives simple step-by-step instructions for how to disassemble an electric clock and how to repair an analog alarm clock mechanism that doesn’t ring on time, and how to repair an analog alarm clock mechanism that doesn’t ring at all. This Fix-It Guide on electric clock repair tells how an electric clock works, what often goes wrong, how to identify an electric clock problem, and what parts and tools you will need to fix it.
When clocks don’t work, we’re late for something.
