How to Fix a Doorbell Chime Box

These are some common ways to fix a doorbell chime. You need to follow the below steps one by one to fix any related issues with your doorbell chime

Step 1: Remove the cover

To check if your doorbell chime works or not, open the cover first. You can smoothly open some of the chime outlet covers by pulling only. On the other hand, some outlets are tightened up with screws. In this case, you will require a screwdriver. Carefully, use it to remove the screws one by one and open the cover.

Step 2: See if there are any broken parts

After opening the chime outlet cover, try to make sense between the wire connections, plungers, and other mechanisms. Look for any mistakes, broken things, or unusual things. Check whether the springs and the plungers are working correctly or not. If you find any wiring issues or other problems, you can just reinstall with a new wire. Otherwise, keep looking for more contemporary problems.

Step 3: Check the electrical screws

If you don’t see any noticeable errors inside your chime and it still doesn’t work, try tightening the electrical screws. Sometimes, these screws get loose due to electrical oversupply. But make sure you are careful while doing it. Though these wires possess not more than 24 volts of electricity, you still have a chance of having a shock hazard unless you are cautious.

Step 4: Press the button and observe

It is another way to check the problem with your doorbell chime. Tell someone to press the doorbell button at your door while you are in front of the exposed chime outlet. Notice any specific movement inside the box when the person presses the button. If you see a slight buzz or action, it will mean the power supply is fine, and the problem is inside the chime only. Usually, the movement will be like a vibration. So, get prepared early!

Step-5: Fix if you see any error

Notice significant things inside the chime box like terminal screws, circuit breakers, fuses, etc. If you see any broken or not tightened enough things, try to fix them with screws and tapes if required. Tell someone to press the button again. If it still doesn’t respond, you will need to go to the next step.

Step 6: Notice the plunger movement

At this point, your only option remains to check the plunger movement. If someone pushes the button, usually the plunger will click, and the bell will ring. Try to pull or push the plunger with your hand. If it doesn’t drive or doesn’t come back to its position, there is a chance of dirt getting stuck inside the plungers. Usually, specks of dust can prevent the plunger from clicking. In this case, you have to clean the whole compartment!

Step-7: Clean if you sense dirt

If you feel like there is dust, clean the whole box first. To clean, take a wet cloth and start cleaning the moving parts first. Do not use oil, silicon spray, powder, or other substances since these are sticky and will jam the plungers instead. Start slowly and be gentle with the wired doorbell chime box. Do not clean harshly, or else things might get worse.

Step 8: Spray the plunger

To clean the plungers accurately, you can use an electrical contact cleaner. Spray at the plunger while moving it up and down. It will rinse out the dirt or dust inside the plunger. Keep spraying and cleaning the water until the plunger movement is smooth. Use a cotton cloth to wipe out the contact cleaner later to finish cleaning the plunger.

Step-9: Reinstall the chime

Reconnect the plunger correctly now and make sure that every wire, fuse, and other mechanism is at its respective places. After that, re-install the chime box and press the button again to test if the chime rings or not. If it rings, you can finish your repairing, but if it doesn’t, you need to move on to the next step.

Step 10: Check the voltage rating again

Take a voltage meter to check the voltage of the chime outlet. Sometimes electrical oversupply can shift the voltage. So, try testing the voltage with the meter. Usually, the voltage will be 12-24 Volts. You can find the accurate voltage of your system in the written manual or on the back of the doorbell. After checking the voltage, if you see the number shown in the meter matches its actual voltage, your doorbell is fine. But, if it doesn’t show precise voltage, you will again have to change the wiring and re-install it to finish the repair process.
