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.

Microwave turn table quit rotating


With the model number, we may have been able to give you a link to the actual service manual. Without it, we can only give you general answers.
The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes, then try it again.

The turntable pad is used to turn it off for cooking without the turntable, then to turn it back on when you do want to use the turntable.You can find links to helpful exploded view diagrams and part ordering help here.

The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

In some brands, you have to cut the motor cover off with snips, then use a screw when reassembling it.

I replaced an old Malibu 300 watt powerpack with a new digital 300 watt Malibu power pack and when I turn it on it runs for about a miniut and then shuts down. I have 15 11watt light on it, the same as the...


300 watt power pack should have 300 watt load.
You have 165 watt load.
Copy following link for general tips to get Malibu power pack to last longer.
http://waterheatertimer.org/Malibu-power-pack-stopped-working.html

Problem might be the photo eye.
http://waterheatertimer.org/images/Malibu-8100-9045-01-large.jpg
Rotate manual dial to ON position and see if lights turn ON.
Keep in mind the digital power pack has photoeye that is light sensitive, and must be exposed to dark light to activate.
For timed functions. Rotate manual dial until it points at timer. Press clock set function button, and use up-down buttons to set current time. Press timer ON button, and then use up-down to set ON timer. Then press timer OFF button , and use arrow keys to set OFF time.

This product has 1 year limited warranty, contrast with old-type analog power pack with 5-year warranty.
Malibu does not even post a manual on their site, which might have troubleshoot section to illuminate why your system has problem,

Rotating dial no longer turns. lights come on ehrn rotated manually.


You posted under Malibu power packs:
Open following link for troubleshoot steps, manuals, warranty information:
http://waterheatertimer.org/Malibu-power-pack-stopped-working.html

If timer dial is no longer rotating, the clock motor is bad.
There are no replacement clock motors for Intermatic/ Malibu.
http://waterheatertimer.org/Intermatic-trippers-and-parts.html

Work around problem: buy cheap plug-in timer, set power pack to override, and plug power pack into cheap timer.

I changed the t8845pv timer and the clock dial does not move either. When I moved the dial manually the selenoide goes on and the system works but I can not make it work automatic. Any ideas?


Are you sure wiring is correct.
If Line wires from breaker box are reversed, the clock motor does not get power, so clock does not rotate.
Separate wires and turn power ON, and then test each wire to bare ground. Tester lights up on Hot wire.
Then test Hot wire to each other wire except bare ground wire, and tester lights up on Neutral.
On the wiring diagram, Hot wire is L1, and Neutral is N

Also check voltage of clock motor. If unit calls for 240V and your line wires are 120V, then clock does not rotate.

Intermatic site is down this weekend and I can't access manual to see exact wiring.

Add a comment with more details.
Intermatic site will be up again tomorrow and I will look at manual and post on this thread if needed.

Power is good going into the timer but the timer is not running. I am wondering if there is a fuse that needs to be changed or a reset switch? The timer has been replaced in the last year.


If I understand correctly, you have T-104 240V timer.
Timer was running fine before, and recently stopped working.
If this is not your timer, add a comment.

1) Click manual override back and forth to see if Load turns on-off.
If Load does not turn on-off, then check power at Load.
Timer has 5 terminals A 1 2 3 4
Check terminals 2 and 4 for 240Volts when Load is ON

2) Check terminals 1 and 3 for 240Volts to make sure timer has full 240V and breaker is not tripped OFF on one leg. If timer has 120V, it appears to have voltage, but clock will not rotate and Load will not turn on-off. Check breaker for 240V across both screws.

3) Is dial rotating?
If dial is not rotating or is stuck in place, replace 208-277V clock motor.
http://www.grainger.com/Grainger/timer-accessories/timers/electrical/ecatalog/N-8hi
http://www.grainger.com/Grainger/INTERMATIC-Time-Clock-Motor-1PNK2?Pid=search

4) If dial is rotating, but trippers don't flip on-off lever, then trippers may be worn down. Buy new trippers.
http://www.grainger.com/Grainger/INTERMATIC-Timer-Tripper-2E054?Pid=search

5) How to wire T104 timer
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

How timer works
:
Clock motor rotates dial.
ON-OFF trippers on dial contact lever.
ON tripper pushes lever one direction.
OFF tripper pushes lever other direction.
Lever moves electrical contacts together, or pulls contacts apart.
When lever moves on-off, manual override lever also snaps back and forth with audible clicking sound.

Sounds like you need new ON pin
http://www.grainger.com/Grainger/INTERMATIC-Timer-Tripper-2E054?Pid=search

d3c9f33.jpg

The ON-OFF pins rotate around until they come in contact with a lever. The clock motor pushes the pin forward until it clicks the on-off lever. The pins are softer metal than the lever, so the pins wear out.

If you need a new T-103 timer some day > the new timer mechanism can snap right into the old box without changing boxes.

If the dial is not rotating, then you can replace the T100 series 125 Volt clock motor (the T103 clock motor is 125V)

Can't seem to get the correct time ever since daylight savings


Make sure that the DST switch on the back of your clock is turned ON and that your clock is receiving the WWVB signal (see manual). If the clock is more that two years old it's set to the old DST changeover schedule and that cannot be modified. If it's on the old schedule, your best bet is to turn the DST function OFF and manually change your time zone twice a year. This, however, will probably not solve the problem if you're in the Eastern time zone -- your only option will be a new clock. For an operating manual on a model similar to yours, visit:
