I do not recognize this number, so if you give the make and model number of the freezer or refrigerator you have.


Time clocks I have used are Paragon 8145-00 for 120 Volts or Precision 6145-0

With terminals 1-2 Power, 3- (Normally Open) Defrost Heater, 4 Control (thermostat or low pressure) Normally Closed, N- Neutral X- Termination Solenoid.

In defrost N-3 power for heaters as NO switch is now closed and N-4 NC switch is now opened.
You have a bad NC switch in the time clock, that is why you get 120V 3-Ground.
Remember electricity travels the path of least resistance.See the following

When checking outside light the timer is going to, the multimeter reads 120v but the lights will not turn on. There are also outside outlets on the same circuit and they are reading 105v but cannot run...


Turn off power between each action listed below.

Is dial rotating and keeping time on timer?
This will tell you if 120V is arriving and working at timer.
Cut ground wire and check circuit again.
This can narrow down ground fault problem.
Disconnect wires from timer and connect wires direct to outdoor lights.
This will tell you if timer is suspect.

List all things on same circuit breaker, and test each to find which are working.
Each electrical box is connected to next box and to next box back to circuit breaker.
Open each box and check for loose wires, signs of burning.
This will narrow down location of problem.

When working in main breaker box, the wires on main breaker have power at all times, even when main breaker is turned off. This is true unless meter is pulled. Always stand on dry boards and never lean into or touch anything else when working in main box. Do not hold screwdriver between teeth.
Tape tester leads to wood sticks to keep hands away from voltage.
Test voltage at circuit breaker. Make sure neutral and ground are attached tight on busbar. Make sure black wire is attached tight to breaker. Move black wire to another same-size circuit breaker. Disconnect ground wire and test circuit again to check if ground fault is causing problem.

When power is applied load one reads o.k. load two reads zero why?


You posted under EH40 240Volt programmable timer.
http://waterheatertimer.org/How-to-wire-EH40-hot-water-heater-timer.html

If I understand correctly, you are testing the terminals when timer turns ON?
Test shows 120V between terminal 4 and ground wire.
Test shows 0 volts between terminal 6 and ground wire.

Solution:
Test terminal 3 to ground -and- test terminal 5 to ground and make sure each tests 120V.
Test terminal 3 to terminal 5 for 240V.

If terminals 3 and 5 test correctly, but terminal 6 never has power, then relay inside timer has gone bad.

Looking for a timer to turn a 120volt 2amp water pump on for 1min 2 times aday that will last for more than 3 years please help


1) You need 120V timer to control 2 amp water pump.
V x A = watts so 120V x 2amp = 240 watt
754 watts per HP divided by 240W = 1/3 HP horsepower.

2) To get 1 minute time periods, you need electronic timer.
Most electronic timers have minimum 1 minute set time.
Same schedule each day, you can use 356-day, 7-day or 24-hour electronic timer.

3) To have electronic timer last longer than 3 years you need a clean circuit and expensive timer.
Use circuit analyzer to check circuit. Hire electrician to check circuit and replace pump if necessary to make sure timer will last as long as possible.

4) Intermatic ET70115C should last for many years. Battery is replaced every 8 years.
http://www.intermatic.com/products/timers/electronic%20time%20switches/next%20generation%20time%20switches.aspx
ET70115C $379
http://www.1000bulbs.com/product/3391/ELEC-ET70115C.html

5) You posted under EH10 water heater timer, which is inexpensive water heater timer rated for 1HP. You can't expect inexpensive timer to last as long when using a motor, although 1/3 HP is lightweight motor.

6) You can buy five EH10's for same price as one ET70115C.

New intermatic T101 timer problem - timer is not


Manual override lever is good overall test of T101 120Volt timer.
T101 timer has 3 terminals: A 1 2

See wiring diagram on following link:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101

Electricians test, they don't guess.
So test your wire:
Separate all wires for testing.
Use ordinary 2 prong tester.
Tape wood sticks to tester leads to keep hands away from power.
Stand on dry boards. Do not hold or touch anything metal.
Turn power ON.
Test each wire to bare ground wire.
Tester lights up on Hot wire. 120V circuit has only 1 Hot wire. If you have 2 Hot wires, you might have 240Volt circuit and need T104 timer. If circuit has 1 Hot wire, then that Hot wire must connect to terminal 1.
If you have NO Hot wire, then check circuit breaker.
Hot wire is identified.
Now test Hot wire to all other wires, except bare ground wire.
Tester lights up on Neutral wire. Neutral wire must connect to terminal A.
If you have NO Neutral wire, then additional wiring is needed, or circuit needs further testing to see what type of wiring you are working with.
Bare ground wires connect to green ground screw.

Notice there are small white wires also connected to terminals A and 1. These small white wires power the 120V clock motor. With Hot on terminal 1 and Neutral on terminal A, the clock motor will run, and yellow dial will rotate.

If timer dial does not rotate after connecting Hot ans Neutral, then test voltage across Hot and Neutral to make sure it reads 120V.

Your circuit should have 2 wires remaining.
These wires go to 120Volt load (fan, light, motor)
Connect these two wires to terminals A and 2.
Try manual override.
If Load turns ON-OFF, then timer is wired correctly.
If Load does NOT turn ON-OFF, then reverse Load wires on terminals A and 2.

Add a comment any time.

How to wire a intermatic timer T104 240 v to a 120v?


T104 is 240volt timer.
Timer has terminals A 1 2 3 4
T-104 clock motor must receive 240Volts to operate.
Clock motor wires are white-colored and can be seen connected to terminals 1 and 3.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
http://waterheatertimer.org/images/Back-of-WH40-2b.jpg

There are two work-arounds for using T104 for 120V.

1) Diagram 1 showing how to change wiring:
http://waterheatertimer.org/images/T-104-control-120V-Load-500.jpg
Move 240V clock motor wires to terminal 1 and A.
Connect 240V Hot leads to terminals 1 and A. This will power the 240V clock motor
Hot wire going to 120V load connects to terminal 2. This wire will be turned on each time timer turns on, and 120Volts will power the 120V load.
To complete 120V circuit, neutral wire that comes from neutral busbar in breaker box connects to 120V load.

To control additional 120Volt circuit, run jumper wire from terminal 1 to terminal 3.
Connect Hot to second load to terminal 4.

2) Second method is to change T104 timer into T103 timer:
http://waterheatertimer.org/images/T-104-control-120V-Load-2-5.jpg
Replace T104 240V clock with identical 120V clock motor from Grainger
http://www.grainger.com/Grainger/INTERMATIC-Time-Clock-Motor-1PNK1?Pid=search
Neutral wires connect to terminal A.
Hot wire from Breaker connects to terminal 1
Hot going to Load connects to terminal 2

To control additional 120Volt circuit, run jumper wire from terminal 1 to terminal 3.
Connect Hot to second load to terminal 4.

WH40 water heater timer: Does black wire from service box go to terminal #1 and black wire to water heater to terminal #2? Does neutral (white) from service box go to terminal #3 and neutral (white) to...


WH40 is 240Volt timer.
WH40 will not work with 120V circuit.

See WH40 wiring illustration at following link:
http://waterheatertimer.org/How-to-wire-EH40-hot-water-heater-timer.html

There are two hot wires in 240V circuit because every circuit requires two wires to complete the circuit.
Hot wires from breaker connect to terminal 1 and 3.
Notice that small white wires are also connected to terminals 1 and 3.
Small white wires power clock motor located on back of mechanism, so this says power from breaker box must arrive on terminals 1 and 3. This insures that clock motor runs continuously.
If clock motor only runs when manual override switch is clicked ON, then your Hot and Load wires are reversed.

Bare ground wire connects to green ground screw.
Wires going to Load (water heater) connect to terminals 2 and 4.

FYI: Terminal A is not used unless circuit also has a Neutral wire,
See basic water heater circuit Diagram #2:
http://waterheatertimer.org/240-v-water-heater-circuit.html

Terminal A is also used if you want to convert WH40 to 120V timer by replacing 240V clock with 120V clock.

The T104p3 timer is getting power but the clock won't turn and the manual switch also doesn't work. we had a power outage, and the timer has not worked since then.


If I understand correctly, your T104 240Volt Intermatic timer worked fine before.
Now the clock will not rotate.
The manual switch doesn't operate the load.

You checked for electricity.
But did you check for 240 Volts across terminals 1 and 3?
It sounds like the circuit breaker is tripped off on one leg so circuit has 120V and tests positive for power, but not 240V.
Reset breaker all the way over and then click breaker back.

Back to the timer.
If you test electricity at terminal 1 to ground and it reads 120V, that means timer is receiving power from one leg of the 240 circuit.
If you test terminal 3 to ground and it reads 120V, that means same as above.
But unless you test for 240V across terminals 1 and 3, the tests above mean nothing.

Let's understand 240V circuit.
You know all single-phase household circuits require two wires to complete the circuit.
Same is true for 120V and 240V circuits >> each needs two wires to complete the circuit.
Inside the main breaker box are 3 busbars.
There are 2 hot busbars and 1 neutral busbar.
120V circuit is complete with 1 hot wire from either hot busbar and 1 neutral from neutral busbar
240V circuit is complete with 1 hot wire from one hot busbar and 1 hot wire from other hot busbar.
http://waterheatertimer.org/B220C.html
http://waterheatertimer.org/See-inside-main-breaker-box.html

The 240V circuit breaker snaps down over both hot busbars, and then 2 wires come out of that breaker and go to 240V appliance, or to T104 timer terminals 1 and 3.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

If circuit breaker is not delivering on both those hot wires, then all along the way you can test for electricity and test will show 120V but not 240V.
So it appears as though circuit has electricity, but circuit will not operate until both hot wires are available to complete the circuit.

That's why you test for 240Volt across terminals 1 and 3
And also test for 240Volt across both wires at circuit breaker.

Going back to timer.
Unless there was lightning strike that fried insides of timer, but somehow left everything else untouched, the manual override should work if circuit has 240V, and Load (lights, motor, fan) is operable.

A simple test is to move circuit breaker wires to another 240Volt breaker and see if timer works again.
If breaker will not reset, you will have to replace 240 circuit breaker, or add a subpanel if your busbars are burned and broken.

How do you wire a intermatic t103


I'm looking at the T-103 sitting here in my office.
Terminals are labeled: A 1 2 3 4
I have about 10 different Intermatic timers on the shelves & each is a bit different

The T103 has a 120Volt (or 110V) clock motor
You need a white Neutral wire to operate the T103 clock

120V: Let's say your Load (light, fan, pump) is 120V
The white Neutral from breaker box connects to Terminal A
The 120V black Hot wire from breaker box connects to Terminal 1
The black wire going to Load (fan, light, motor) connects to terminal 2
The white wire going to Load connects to terminal A along with the Neutral
Ground wires connects to green ground screw
If your wires from breaker and wires to load are wired in reverse, the timer will turn ON the Load but the timer will not shut the circuit OFF.
To test which wire is Hot and Neutral, look at explanation at bottom of page.

240V: Let's say your Load is 240 Volts (or 220 Volts)
The clock motor is still 120V so you still need a white Neutral wire connected on Terminal A
Now you have 2 Hot wires coming from breaker box
Hot wire 1 from breaker box connects to Terminal 1
Hot wire 2 from breaker box connects to Terminal 3
Wire 1 going to Load connects to Terminal 2
Wire 2 going to Load connects to Terminal 4
Ground wires connects to green ground screw

What if you don't have a Neutral wire and you are wiring a 240V circuit?
240V circuits normally have 2 hots and a ground, but no neutral
Buy the T-104 timer
The T-104 has a 240V clock motor
Wiring for the T-104 is exactly the same as 240V wiring shown above for T103 EXCEPT there is no Neutral on Terminal A, and Terminal A is bare
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

How to test which wire is Hot
Test requires wires with live electricity >>> this is not advisable without precaution
Stand on dry boards, do not touch anything metal, wear dry clothes, do not hold screwdriver in mouth, wear gloves, tape tester leads to wood sticks so hands are away from power
Remove wires from terminals
Separate wires so they can be tested
Turn on power
Test each wire to bare ground wire
Tester lights up on Hot wire(s)
If circuit is 120V, then there is only one Hot wire
If circuit is 240V, then 2 wires will test hot to ground >> these wires will be Hots 1 & 2
Test assumes circuit breaker is functioning normally.

How do you test for neutral?
If you have 120V line with only 1 hot wire, then one of the white wires will be Neutral?
Test Hot wire to each white wire
Tester lights up on neutral

How do i wire my diehl 880 ?


1) Here is Diehl 880 instruction manual

2) Diehl 880 is 120V timer
-1/2 HP
-1000 Watt tungsten. Tungsten means incandescent light bulbs.

3) Checklist:
a) Your load does not exceed capacity > Timer is too lightweight to control 1500 toaster oven.
b) You need 120V line coming from breaker box with black Hot wire and white Neutral
c) You need 120V line going to Load that also has black and white wire
d) Test each black wire to ground to see which black wire is HOT

4) Deihl 880 sell sheet pdf says 880 is available SPST (single pole single throw) -or- SPDT (single pole double throw).
-The difference is pole #4 on the timer.
-If you are trying to turn one circuit off just as another circuit turns on, then you need the SPDT
-If you are turning one circuit on-and off, then the following instructions are for you

5609d99.jpg

5) Wire clock
-There are 5 poles > look for markings 1-thru-5
-If no marking, then poles 1&2 are probably spaced apart from other poles
-Connect Hot and Neutral wires to poles 1&2 >> this powers clock motor, they go on either pole

-Pole 4 not used

6) Wire timer
-Poles 3&5 are timer circuits
-Connect Hot line to pole 3
-Connect black wire going to Load to pole 5
-Connect white wire from Load to Neutral

Freezer section works, refrigerator becomes warm.


In the defrost circuit there are three major parts. Defrost timer, defrost heater(s) and defrost thermostat. Defrost timer failure will not put power to the circuit. Defrost heater failure will fail to defrost when the timer applies power. Defrost thermostat must be closed for defrost to take place. FIRST located the timer, rotate the Clutch head screw clockwise SLOWLY until one distinct click is heard. Timer will be in defrost mode and defrost should happen in 18-22 minutes after which the refrigeration should start cooling again. If defrost takes place and it does not go back to cooling automatically turn the screw once again until you hear the second click, unit will start. Replace the timer. If defrost does not take place in the time frame above and the unit restarts in cooling test the defrost heaters. From the heater(s) follow the wires from each end to where they plug into the circuit. Unplug them and test through the heaters with an OHM meter. You should get a reading if they are good, if no reading replace the heaters. If you get a reading on the heater(s) replace the defrost thermostat.
