If you have Intermatic timer, then clock motors are available for most hard-wire box-type timers. Most pool and spa timer modules are available or have same/similar replacements. If you have plug-in timer, including power pack or portable outdoor timer or indoor plug-in or in-wall timer, then no clock motors are available.

If you have Tork timer, then clock motor is available for 1100 series.

If you have Paragon timer, clock motors will be hard to find
http://waterheatertimer.org/Paragon-timers-and-manuals.html
If you have other brands of timer, then clock motors are not available except Deihl, DIGI and Grasslin timer modules, but post brand and model number of timer so I can search my files.

Can I purchase intermatic timer motor 240v 50hz P/N WG 1574 10D in Australia?


The motor will turn faster with higher frequency because the phase changes is faster. No damage to the motor. Just ensure that the voltage is within the operating range. Amperage kills the motor, subjecting high loads on it will eventually burnt it's windings and become expensive to repair.

Why when i just installed a new T104 timer yet seems wont turn on with pins


Are you sure that you put the pins on right? They have little projections on the bottom that turn the timer on/off as the cam moves through its 24 hour rotation. The little gear in the back is connected to the motor and because it is spinning that tells you that the motor is definitely good.

Pool pump breaker tripping


1) Not likely the timer is problem, unless there was fire or overheating in timer box. Use nose and eyes to inspect for signs of high heat.

2) Eliminate timer as suspect:
Move wires on timer to test if timer relays have gone bad.
Move terminal 4 to terminal 3
Move terminal 2 to terminal 1
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T104

3) Check watt rating of Hayward pump, and voltage.
1Hp motor at 240Volt draws 8 amp, and can draw 6 to 8 times that amount when starting. Up to 100 feet, should be at least 12 gauge wire and double-pole 20 amp breaker. Over 100 feet, 10 gauge wire and 30 amp double-pole breaker is best.
http://waterheatertimer.org/Color-codewire.html#motor

4) Intermatic T104 240V timer is rated 40 amps
Can safely handle 1 Hp motor without nearing heat-rating capacity of timer

5) Make sure the motor is wired correctly for 240Volts.
If motor is wired for 120, and 240 is applied, then tripped breaker can result.

VIDEO INSTRUCTION ON T104 CONNECTION


There are many ways to wire T104 timer, depending on what type of load you are controlling and which voltage you have, plus the timer can be converted into different voltages by changing clock motor, or clock motor wiring.
I don't know how a video could cover all those different ways.
Copy following link for clear illustrations:

Maybe you could use each diagram on link above, and made this video yourself and post it on utube

My WH40 makes a loud hum, but it works well. It is about 20 years old, and didn't make this noise until fairly recently. Could the motor be requiring replacing?


1) Yes, the noise is from clock motor turning the gears.
When timer is new, parts have a bit of white grease on them.
Turn off power and spray WD 40 or apply some white grease and see if that helps.

2) Yes
WG1573 240Volt clock motor is going bad.
Tip out mechanism using thumb spring located top inside box and check clock motor number.

Buy
WG1573 240Volt clock motor and extra trippers from Granger number 1PNK2

TIMER HAS STOPPED ROTATING, DO I NEED A NEW TIMER UNIT OR CAN THIS BE REPAIRED. SHOULD I USE WD40. PLEASE EMAIL susan.labi@hotmail.co.uk THANK YOU


1) It depends on timer you have.
Intermatic-brand box timers used to control water heaters, outdoor signs, pool pumps and parking lot lights generally have replaceable clock motor.
paragon-brand clock motors are not available.
Tork-brand clock motors are more difficult to find, depending on model number.
In-wall timers & plug-in timers are not repairable, and you buy a new timer.

2) Add a comment and describe your timer.

3) ook on following links to help identify timer.

Timer will not turn water heater ON at set time, has to be done manually. However, it will turn water heater OFF at set time.


If this is new installation, check wiring. Hot and Load wires might be reversed.
Check that ON OFF trippers are both attached to yellow dial.
http://waterheatertimer.org/How-to-wire-WH40.html

If timer worked fine before, and started missing recently, then tripper pins probably worn out.
Trippers contact mechanical lever, and push lever on-and-off.
Trippers are softer metal and designed to wear out before lever.
If lever is worn out, timer needs to be replaced, but try new trippers first.
Buy trippers at Grainger
http://www.grainger.com/Grainger/INTERMATIC-Timer-Tripper-2E054?Pid=search
http://www.grainger.com/Grainger/timer-accessories/timers/electrical/ecatalog/N-8hi

How WH40 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-and-off, manual override lever also snaps back and forth with audible clicking sound.

Using q-tip, add touch of white grease to lever where trippers contact.

Grundfos recirculating system. Never has produced semi instant hot water at sink it is installed on. Could the original comfort valve be defective


http://waterheatertimer.org/Water-heater-recirculation-system.html

The circulation system should draw hot water directly from the water heater as shown on illustrations on link above.

The Grundfos pump works on a thermostat, and some work on a timer.
Can you hear the pump working?
There should be a humming sound.
Check the timer -or- thermostat setting.

It is possible the lines are clogged with sediment if you have hard water.

If I was going to fix the problem:
1) check thermostat or timer
2) listen for pump sound
3) check electricity going to unit
4) take apart the pipes and inspect for clogging
If there is a clog, I would flush the line or soak the part in CLR (calcium lime rust remover)

The circulation pumps are sealed and there is no way to take apart the motor, timer, or thermostat for repairs.

add a comment if you need more assistance.

Timer motor does not turn


make sure you purchased nthe correct timer and not a 220 volt timer for water heater use , you could still turn on and off manually but you would need 220 volt to run timer may sound silly but i have seen it several times before , look on the door plate and be sure it is a 120 volt 1 phase tmr motor
