How to Fix a Clicking Relay

In this post, we’ll provide step-by-step tips on how to fix a clicking relay, locate any damaged components within the circuit board, and repair them in order to restore your device’s functionality and reliability. So if you want to get rid of that annoying clicking sound once and for all – read on!

What Causes Clicking Relay?

The most common cause of a clicking relay is a damaged or faulty connection within the circuit board. This could be due to corrosion, physical damage, or even overheating of one or more components. In any case, the result is an interruption in the flow of electricity through the circuit, resulting in loud and disruptive clicking noises. 

The relay switch is essentially a small mechanical device that helps regulate the power levels within an electrical system, and if it’s not functioning properly, you may experience a number of problems, such as flickering lights or other equipment malfunctions.

How to Locate the Problem?

The first step in solving the problem of a clicking relay is to locate the faulty component within the circuit board. The best way to do this is to use a multimeter to measure the voltage levels across all of the wires and components. If you find any discrepancies, that’s when you should start looking for signs of damage or corrosion.

Once you’ve found the faulty component, it’s time to start troubleshooting and repairing. Depending on the exact nature of the problem, this can be done in several ways.

Needed Tools & Supplies

In order to diagnose and fix your clicking relay, you’ll need a few essential tools and materials. These include:

  • Safety gloves and sunglasses
  • Screwdriver
  • Multimeter
  • Electrical tape
  • Soldering iron & solder wire

10 Steps on How to Fix a Clicking Relay

Step 1: Unplug

Unplug the Device From Any Power Source

Unplug the device from any power source and put on your safety gear. Unplugging is essential for safety reasons, as it will ensure that no electricity is flowing while you work on the circuit board. The flow of electricity can be dangerous and cause serious injury, so make sure your device is disconnected before you begin.

Step 2: Inspect

Carefully inspect the circuit board for any signs of damage or corrosion. Look closely at the wires and components to check for any loose connections or other irregularities. If you see anything unusual, mark it down and move on to the next step.

Step 3: Test

Using your multimeter, test the voltage levels across all of the wires and components on your circuit board. You should be looking for any discrepancies or abnormal readings. If you find one, this is likely where the issue lies.

Step 4: Disconnect

Once you’ve identified the faulty component, you can go ahead and disconnect it from the circuit board. This should be done carefully and with extreme caution – as a wrong move could cause further damage to the relay switch.

Step 5: Replace

Once you’ve disconnected the faulty component, it’s time to replace it with a new one. Depending on the type of component, you may need to solder it into place or use electrical tape to hold it in. Replacing the faulty part should fix the clicking issue.

Step 6: Test Again

Once you’ve replaced the faulty component, it’s a good idea to test it again using your multimeter. This will help ensure that everything is in order and that you haven’t made any mistakes during the repair process.

Step 7: Secure

Using electrical tape or solder, make sure the new component is securely in place. This will help ensure that it doesn’t come loose or cause further problems down the line. Furthermore, it will also add an extra layer of safety.

Step 8: Reassemble

Once you’re sure that everything is in order and the new component is securely installed, it’s time to reassemble the circuit board. Line up all of the components and connections according to their original positions and then reconnect them to the circuit board.

Step 9: Plugin

Once you’ve finished reassembling the device, plug it back into any power source and switch it on. The clicking should have stopped now that you’ve replaced the faulty component. Plugged in and switched on, the device should be working properly.

Step 10: Monitor

Keep an eye out for any irregularities or further clicking relays. If you notice anything unusual, make sure to check it out right away. You don’t want a small issue to turn into something bigger!

By following these steps, you can easily diagnose and fix a clicking relay. While it may seem daunting at first, if you’re careful and methodical during the troubleshooting process, you should be able to find and fix the issue with relative ease.

8 Maintenance Tips

  1. Inspect the relay for visible damage. Look for signs of wear and tear, such as frayed wires or cracks in the casing. If any damage is found, replace the relay before continuing with other maintenance steps.
  2. Check all connections to ensure they are secure and free from corrosion. Clean them if necessary using an electronics cleaner or a cloth dampened with isopropyl alcohol.
  3. Make sure the relay is properly mounted and not touching other components. If it isn’t, adjust the mounting screws or attach a rubber cushion to reduce vibrations.
  4. Lubricate moving parts using a light lubricant such as graphite powder, silicon grease, or mineral oil. Lubricating the contacts and other moving parts will improve the performance of the relay.
  5. Inspect any electrical connections for signs of wear or corrosion. If necessary, replace damaged components with new ones. Any corrosion should be removed using an electronics cleaner or a cloth dampened with isopropyl alcohol.
  6. Test the relay by connecting it to a power source and actuating the switch. If it still clicks, then the problem may lie within the relay itself, such as with its coil or contacts.
  7. Replace any parts that are worn or damaged. This may require soldering new parts onto the existing relay, so make sure you have the necessary skill and tools to do this safely.
  8. Finally, check the safety rating of the relay and make sure it is still suitable for use in your application. If not, then consider replacing it with a higher-rated one. Replace any other components that have been affected by the problem.

Following these maintenance tips will help keep the relay in good working condition and improve its performance. However, if any of the above steps fail to resolve the clicking issue, it may be necessary to replace the entire relay with a new one. If you do not feel comfortable doing this yourself, then consult an experienced technician for assistance.

Frequently Asked Questions

How Much Will It Cost?

The cost will depend on the type of relay you need and any replacement parts that may be necessary. It is recommended to consult a qualified technician or professional for an accurate estimate. It solely depends on the type of relay and the complexity of the job.
