60 HERTZ TIMERS - Dryers

No, hertz (Hz) is the name for "cycles per second". Normal AC power (in the USA) is 60 hertz or 60 cycles per second. 1 kiloherz (KHz) = 1000 cycles per second. 1 megahertz (MHz) = 1,000,000 cycles per second. Amps is the measurement of current flowing through a device or circuit. a 100 watt light bulb pulls about 0.9 amps. A toaster or microwave oven pulls about 15 amps.

50 Hz means the electric generator rotates 50 times per second.
And then electricity oscillates or reverses polarity 50 times per second.
Products rated for 60 Hz will not operate correctly with 50 Hz power.

Make sure you don't have loose wire on the circuit breaker or neutral busbar inside breaker box.
Move wires to another same-size breaker to eliminate breaker as suspect.
Make sure that only copper wire is inserted under terminal screw plate at timer, and no insulation is under screw plate. Check that stranded wire and solid wire are not on same terminal screw, and that wire gauges are same so you don't have #8 and #10 under same screw plate.

Some of the new generation box timers from Woods and GE run fast and slow.
The clock motor is not connected directly to voltage from breaker, but instead the power is routed through electronics so the installer can select different voltages. Some models automatically detect line voltage.

Intel was working on the speed problem for GE in 2010, but I don't know the result.
The speed-reliability problem is fairly common, and continues since I received another e-mail about the issue a few weeks ago, and I'm certainly not first on the list to receive reports.

Possible cause:
Clock motors and all analog motors rotate a certain speed based on electrical winding and on electrical hertz or Hz. Hertz is the number of cycles per second that the electrical wave oscillates. Electricity is a wave, and Hertz is the wavelength. This wavelength is regulated at the power station, although there is a move to relax strict adherence to specific wavelengths to save money.
In the US, 60 Hz is standard, and you can see that number printed on electrical devices like your TV.
In Australian, 50 Hz is standard. For example, a 50 Hz motor would run different speed in the US.

I don't know if Hz is the speed-problem cause, or if Woods makes timers to meet the different Hz markets.

The fact that you got two timers with same problem makes me think there could be a mix-up in the product shipment, or simply a bad batch of timers. I've tested these timers and found them to be made much cheaper than predecessor time pieces like Intermatic GM40 electronic series.

I recommend Intermatic mechanical timers for pool pumps instead of the cheaper-made Woods and GE electronic timers. The clock motor is wired directly to power source, and replacement parts are available. Plus the mechanical timers are not as vulnerable to product failure and power surge.

First check the voltage, if the voltage is good then check the hertz with a different meter because if the hertz went up to 120 everything onboard should have burnt out. The hertz works on the low voltage side of 120vac. before going to a repair shop first check the hertz meter. Good luck.

I don't know if you already solved the problem, but did you check what the maximum output power of your aircraft is? The nespresso machine needs about 1250 Watts, which is a lot of power. A vacuum cleaner or microwave use less power than that (maybe between 800 - 1000 Watts). Maybe that difference is the reason. Also, you mentioned that you converted from 220V 50Hz to 120V 60Hz. I think you only converted the voltage, a frequency converter would cost thousands of dollars.

Hello. American made tools are made to operate on 60 hertz, but they will operate on 50 hertz. Given a choice, such as when operating off of a generator, select 60 hertz.

u.s. is all 60 hz. not sure in the phillipines,the only issue is it will cook slower due to the lower input frequency, it shows no electronic control board in the diagram, sometimes a different freq. can throw electronics off i.e. the clock would run slower and not keep accurate time on 50 hz. as it would on 60hz.

This is a frequency issue 50 hertz for Europe, 60 hertz in US. It's speed related. Faster RPM for 60 Hz

Check engine speed, frequency is a function of speed.

The specifications for this set list the power consumption at 250 watts so allow for a little extra and go with a 500 watt converter. Also, make sure the converter will change the UK's 50Hz power to the 60 Hz power required for the set. To be exact, the converter must change the UK's 230 volt 50 hertz power to 120 volts (100 will do) 60 hertz. Do NOT attempt to run the TV on 50 hertz power as it is likely you will damage the set
