99% chance the Timer wires are reversed ... and line from breaker and line to pump are reversed. Or remotely possibly the circuit is 240V, and somebody changed clock motor on old T101 from WG1570 to WG1573, converting old T101 into T102...

Wire a time switch to a pool pump motor

240Volt can be turned ON-OFF by cutting power to one of the two 120Volt wires in the 240Volt circuit. You need Neutral wire for 120V, while 240V does not require neutral wire.

If you have Intermatic 120Volt box timer such as T101 or T103, then 120Volt WH1570 clock motor on back of timer can be changed to 240Volt WG1573.

Other brands timer, it might be possible to change clock motor.
Add comment with brand and model of timer.

If the timer turns OFF power to salt computer, the computer will not operate until power resumes.

Wiring for timer

T101P3 is ordinary 120Volt T101 mechanism inside a beige plastic box.
Rated 40 amp.
Three terminals A 1 2
Very small white wires that power the WG1570 clock motor are connected to terminals A and 1.

White neutral wire from breaker box connects to terminal A
Black Hot wire from breaker connects to terminal 1.
This will power the clock motor, which will switch the timer on-off.
Green ground wire and bare copper wires connect to green ground screw.

115volt motor should have 2 wires.
Connect white wire to terminal A
Connect black wire to terminal B

1) If circuit breaker is not tripped or shorted, then timer clock motor has probably gone bad.

2) Some places still sell paragon timers, depending on model number.
But model number given is for 240Volt timer.

3) The clock motor is not available that I can find.
Paragon is no longer making the 4000 series timers or parts

4) Model number given does not match wiring terminals shown in manual.
4014 is DPST 240Volt timer with 4 wiring terminals labeled 1 2 3 4.

5) Paragon 4000 series timer with terminals 1 2 3 is 120Volt timer.

6) Replace 120Volt timer with Intermatic T101 indoor timer or T101R outdoor timer.
Crossover wiring:
Paragon terminal 1 goes to Intermatic terminal 1
Paragon terminal 2 goes to Intermatic terminal 2
Paragon terminals 3 goes to Intermatic terminal A

Honestly, I would just like to turn off the timer. It is in my office serving no purpose and making an incessant noise. any advice

You posted under Intermatic box timer.
There are three ways to turn off timer.
1) Turn off circuit breaker momentarily, disconnect black power wire that connects to terminal 1, and then cap off wire. -Or- remove all wires and cap off each wire, then take timer home and put on your lights or pool pump. Basic 120volt timer is worth about 40$+.
2) If you do not have access to circuit breaker, you can risk life. Wear gloves. Stand on dry surface. Use insulated wire cutter, and a) cut black wire that connects to terminal 1 and cap off wire and/or b) cut several wires one at a time and cap off each wire.
3) Remove trippers from dial. Result: 3 watt clock motor continues to run, but timer will not click on-off. You can still control whatever is wired to timer by clicking override switch back and forth.

Need trippers for older unknown model number amf paragon pool timer. timer is 15 - 20 years old

Paragon no longer makes timers or parts, except defrost timers.
Typically, defrost timers are not used for pools.
Open following link to possibly identify timer and tripper part number.

If you want a new timer for pools, Intermatic makes the T101 120Volt and T104 240Volt:

If you want T100 series timer with fireman's switch that turns off heater 10 minutes before turning off pump:

If you have energy-saving 2-speed pool pump, and thermostat and pool light, then buy P1353 digital timer with enclosure. Enclosure and timer sold together as P1353ME.
P1353 is not easy to wire or program for novice, so you can add a comment or repost question on fixya and I will catch it.

I don't think the timer is causing the problem.
There is no delay switch on the timer or inside the household electrical circuit breaker or household wires.
The contact point(s) located on back of timer mechanism are mechanically pushed together and pulled apart with the manual override lever.
You can test timer:
Test across terminals A and 1 should show continuous 120V no mater what position override lever.
Flip override to OFF, then test terminals A and 2 should show 0 volts.
Flip override to ON, then test terminals A and 2 should show 120V: If A and 2 show 120Volts and pump is not ON, then problems is between timer and pump or at pump.
Look at wiring terminals on timer. Only copper wire should be under the screw plate. No insulation under screw plate. Two different size wires on same terminal will cause loose connections. Stranded wire and solid copper wire under same screw plate will also cause loose connections.

Sounds like a loose wire or short at the circuit breaker box, timer wiring terminals, or at pump.
Check all screw terminals and wire nuts. Look for smell or signs of heat and burning. Look for connections where two different size wires are connected. Look for connects where stranded wire and solid copper wire connect.

Don't know what is it used for,and how it operates?I don't have any instructions for it.

You posted under T101 timer.
Most box timers have model number and instructions pasted on inside of door.
Instructions can seems a foreign language sometimes.

If your timer is different than T101, then add a comment with timer number.
I have extensive files on timers.

Box timers are generally used for heavy amperage loads like outdoor lights, swimming pool pumps, water heaters, parking lot lights and lighted outdoor signs.
They are surface mounted near breaker box, or in attic or basement, or garage.
Box timers are used in schools to ring bells, and inside factories to run processes and fans.
Some are complicated electronic devices used to control machines with one second precision.
Mechanical box timers are noisy when turning on-off, so are generally not installed in living area of house.

T101 timer is least complicated of any timer.
It is used for ordinary household 120V circuit.
Timer has 120Volt clock motor, and controls 120Volt circuit.
For example 120Volt water heater, or 120V grow lights, or aquarium, or any application up to 2 horsepower, for example timer can be located inside garage to control outdoor lights.
T101R is raintight outdoor box, with rubber gasket on door that seals tight when closed.
Raintight boxes are installed outdoors to operate 120Volt spas and pool pumps.
When box timer is rated for indoor, there is no rubber gasket on door, and that box is called NEMA 1 enclosure.
My local Lowes sells T101 T103 T104 > and each is for slightly different purpose and each wires differently.
Link below shows wiring and manuals for T100 series timers.

Here's how T100 series timer works:
Lift and rotate yellow dial until current time lines up with silver pointer.
Clock motor rotates dial as time passes.
Clock motors are accurate for years, but current time has to be reset after power outage.
ON-OFF trippers are placed on outer edge of dial.
Trippers push a lever, and lever turns circuit on-and-off.
ON tripper pushes lever one direction.
OFF tripper pushes lever opposite direction.
Each time lever is pushed, manual-override lever clicks back and forth with audible sound.

Once T101 Timer Shuts Off will not turn back on

you have the hot and load reversed. the power source should connect to terminal 1. the wire going on to the pool pump should be hooked to terminal 2.

the clock motor is powered off terminal 1 and A is the neutral.

what u have done is hooked the power source to #2 and the load to #1, simply switch them and everything should be fine, here is a link to the wiring diagram for the timer.
