Intermatic timers are a popular choice among pool owners due to their durability. However, like any electronic device, they can experience problems that require fixing. In this article, we will discuss common issues that you may encounter with your Intermatic timer and provide troubleshooting steps to resolve them. By following these guidelines, you will be able to maintain the functionality of your timer without the need for professional assistance.
Most Common Intermatic Timer Problems
1. Timer Clock Not Turning
One common issue with Intermatic pool timers is the clock not turning on. This can be due to a fault in the timer itself or a lack of power supply. To resolve this problem, follow the troubleshooting steps below:
- Check the power supply to the timer.
- Reset the time on the clock.
2. Timer Not Switching Pump On/Off
If you notice that the timer is functioning correctly, but the pump isn’t being switched on or off, several factors may be contributing to the issue. These include loose wiring, misaligned clock faces, faulty On/Off trippers, or a malfunctioning pump. Follow these steps to troubleshoot and fix the problem:
- Inspect the On/Off trippers for damage.
- Ensure that the clock face is properly aligned.
- Tighten any loose wiring connections.
3. Clock Loses Time or Time Incorrect
A timer that fails to keep accurate time can be frustrating. Several factors can cause this problem, such as power outages, loose wiring, or damaged gears. To resolve this issue, follow these steps:
- Reset the clock to the correct time.
- Inspect the yellow clock dial for proper alignment.
- Check the gears for damage or debris.
4. Timer Switching On/Off at the Wrong Times
If your timer is turning the pump on or off at incorrect times, it may be due to a power outage or loose On/Off trippers. Follow these steps to troubleshoot the problem:
- Reset the clock to the correct time.
- Tighten any loose trippers.
- Replace bent or damaged trippers.
5. Middle Time Pointer Moves / Loose
A loose or wiggling middle time pointer can disrupt the timer’s functionality. To fix this, tighten the screw that holds the timer in place to ensure stability.
6. Trippers (On/Off Pointers) Moving
Similar to the timer pointer, loose trippers can affect the timer’s performance. Use pliers or a wrench to reseat the trippers and tighten them at the desired on/off times.
7. Manual On/Off Switch is Tight or Stuck
Sometimes, the manual on/off switch on mechanical timers can become tight or stuck. Apply a lubricant like WD-40 to loosen it, ensuring smooth operation.
8. Timer Won’t Manually Switch Pump On
If you are unable to manually switch your pump on or off using the timer, check for any obstructions or jams in the manual switch. Ensure that there is power to the timer and that the pump is in proper working condition.
9. Timer Stopped After Power Outage
A power outage can cause a timer to stop working temporarily. However, if the timer fails to resume its normal operation after the outage, there may be an underlying issue, such as a power surge damaging the timer or the pump. Troubleshoot the problem using the steps mentioned below:
- Check for any visible damage to the timer.
- Verify if there is power supply to the timer.
- Consider replacing the timer if necessary.
Reasons Why Pool Timers Stop Working
1. No Power to the Timer
The most common reason for a timer’s failure is a lack of power supply. This can occur due to a tripped circuit breaker, wiring issues, or loose terminals. Perform the following checks to troubleshoot this problem:
- Verify that the circuit breaker hasn’t tripped.
- Inspect the wiring between the circuit breaker and the timer.
- Ensure that the terminals on the wires are tightly secured.
2. Gears Stripped or Damaged
Mechanical timers can experience issues with stripped or damaged gears. Check for any obstructions, debris, or missing teeth on the gears. Clean them with a toothbrush if necessary.
3. Yellow Clock Wheel Not Located Correctly
If the yellow clock wheel is not properly seated or located in the timer, it can cause the timer to malfunction. Adjust the clock dial to the correct time and ensure that it sits securely in the timer.
4. On/Off Trippers or Pointers Loose or Damaged
Loose or damaged On/Off trippers or pointers can disrupt the timer’s functionality. Examine them for any visible damage, replace bent trippers, and ensure they are properly tightened.
5. Pump Broken
In some cases, the timer may appear to be the issue, but the pump or the wiring between the pump and the timer is the actual problem. Check for adequate power supply to the timer and consider consulting a qualified professional to diagnose and repair any pump-related issues.
