Make sure that you see the gears turning inside through the inspection port above and to the right of the dial. Make sure the dial is set to the proper time and that it pushed in to place when released. You pull the yellow dial toward you to set the time, if it does not go back (spring loaded), then there is a problem and you can try to seal the dial manually as sometimes the gears done line up. Also make sure the on/off trippers are not interfering with the dial going back into place.

Moved Kenmore electric oven (2 yrs old) and now neither the oven or stovetop heat up. The clock is set.

This may sound silly, but go check your circuit breaker and flip it completely off and then back on. Sometimes it does not completely trip and your clock only needs 120 volts to work which you have, but the heating coils need 240 volts. If you have an older house that has a fuse panel instead of circuit breakers you could have a blown fuse.

Hi, I have few quick questions regarding the Intermatic HB114C 240 Volt, I would appreciate if you can answer my questions 1. Does this unit have Internal Built in Clock to set up the Clock or does...

HB114C timer likely will not work in India.
Contact Intermatic:
Plug type is different than found in India.
India power generation is 50 Hz, so timer might not keep time even with plug adapter.
US power grid is 60Hz, so US-sold products are 60Hz.
Some timers are both 50Hz and 60Hz, but spec sheet usually shows that information.
HB114C spec sheet does not show Hz.

HB114C is analog appliance timer with clock motor that rotates dial once every 24 hours.
The timer does not have a countdown feature.
Trippers are placed on dial.
As dial rotates, trippers move small switch that opens and closes circuit to load.
Current time is set by manually rotating clock dial until current time lines up with arrow located on inner dial.
After power failure, current time must be reset.
There is no way to install a battery back-up inside the timer.

I have the Intermatic T-104. Hate to toss things out if it's just a minor problem. The timer keeps accurate time. The "on" switch doesn't work; the "off" switch does. I...

Open following link to determine if timer is bad:

Key things are clock dial rotating on timer, and manual override lever turning load ON-OFF.
If clock motor is rotating and keeping good time, then you know that timer is receiving 240Volt from circuit breaker.

Check for loose wiring, and then check if you have 240V across terminals 2 and 4.
If you have 240volt across terminals 2 and 4, then that says 240V is going to Load, and that load is suspect.

Buy cheap multimeter from hardware: set multimeter to read 240 or 250V, and put test prongs on terminals 2 and 4, and then move override lever and test again.
Safety: Tape multimeter leads to wood sticks to keep hands away from power. Stand on dry boards. Use adequate light.

If timer is genuinely bad, then you can buy timer insert: T104M
Usually it is cheaper to buy whole new T014, and then snap new mechanism into old box.

I have a hager eh 110 time switch on my pool and I cant set it. Any clues?

Hagar EH 10 is 230V analog time switch.
EH010 is 1" wide.

1) See large image of EH010

2) See large image that explains how to set EH-010

3) With analog timers, there is a movable dial that rotates with fingers.
Pins or segments are located around edge of dial.
Segments are moved one direction or the other to set on-off times.
After segments are set, the dial is rotated to match current time.
The dial rotates as time passes, and segments move a switch that opens and closes electric circuit.

4) EH-010 is different.
Usually analog dial is located on face of timer like a clock face.
However EH-010 is only 1" wide, so dial is perpendicular to front of timer and is rotated with thumb.

5) I suggest setting a few segments one direction or the other and then manually rotate dial full circle to watch when pool equipment turns on-off.
This will tell you if segments should be set right or left.
I have not seen this particular timer, but it appears as if times on printed on edge of timer dial.

6) Timer has 240V clock motor.
So Hot line wires from circuit breaker connect to terminals 1 and 2.
This powers clock motor so dial rotates as time passes.

240V Line and 240V Load wires are connected as shown in image below:

I wired my replacement switch the same as the old one, it seems to shut off and on fine. but it does not keep time, only turns on and off manually. it had no instructions in the box. anyone that kn ows a...

Re-check your wiring. The 2 incoming 240 volt wires from the circuit breaker connect to terminals 1 and 3. The 2 outgoing 240 volt wires going to the load connect to terminals 2 and 4. If it is connected any other way you will get symptoms such as you describe.

The 240 volt timer clock motor is connected internally to terminals 1 and 3, so if you connected the incoming 240 volt wires to say, terminals 1 and 2, then the clock motor is only getting 120 volts. If you inadvertently connected the incoming 240 volt wires to terminals 2 and 4, then the timer clock motor is getting no voltage.

In both cases of mis-wiring stated above, the timer clock motor will start running when the manual lever is in the ON position, and of course, the load will then turn ON.

There is power to the unit but the clock does not rotate. The unit is about one year old. It has to be turned on and off manually.

There are two possible answers:

First, does the timer receive 240 Volts from the circuit breaker? If your 240 Volt water heater heats water when timer is manually switched on, then the answer is yes, and the 240 V circuit is fine.

If the timer is not getting 240 V, it can still appear to have power if 1/2 of the 240 volt breaker is sending power, but the other 1/2 of the breaker is defective. You can test the breaker with a tester, or by moving wires to another breaker of the same size.

The second possible answer is that the clock motor is burned out. WW Grainger sells a replacement for $16. Clock attaches with 2 small screws.
Here is link to Grainger:

How does one wire the T104. Can the T104 be wired via a 120 volt, 20 Amp Breaker Supply

No, the Intermatic T104 requires 240 volts for the clock motor.

The T103 has a 120 volt clock motor and will control a 240 volt load, but requires a 3-wire (with ground) supply cable [as opposed to only a required 2-wire (with ground) for the T104].

The T101 uses a 120 volt clock motor and controls 120 volt loads.
This tip may help:

Apartment size brentwood electric range. The oven, 2 timers to the right of the clock and the outlet on front left have stopped working. Clock works, all top burners work.

Some of these ranges have two plugs, one for 240 volts for the burners themselves, one for the controls. Other issue, could have one leg of the 240 volt circuit not working, might get some heat, but not full power. Check fuses, just to be sure. In any event, you likely have two circuits: 240 volts for the power required to take care of the heat, and 120 volts for controls, timers, clocks. If only one plug, I'd expect to find a blown fuse within the appliance, or some other problem in the 120 volt circuit.

Not sure of your level of expertise to open up and trouble shoot electrical. Need to understand (1) how to kill power and (2) how to safely test a live circuit (at 240 volts.) Make sure meter is always set to 250 or greater volts, AC.

No power

First thing to do is pull the oven and check if there is 240 volts going to the oven. The display works off 1 of the 120 volt legs of the 240. If you have the 240 volts, then your issue is with either the display or relay board.
