If you’re trying to fix a doorbell in Singapore, you’re likely dealing with one of two things: either it won’t ring at all, or it’s only working sometimes. In a place like Singapore, where parcel deliveries, visitors, and food orders are part of everyday life, a working doorbell is more important than we often realize. I’ve been through this myself in my own HDB flat in Sengkang, and what I learned through trial and error is exactly what I’m going to share with you here.
This guide will walk you through how to fix a doorbell with simple instructions, using tools you probably already have or can easily find at a local hardware shop like Selffix or Horme Hardware. LS Electrician Services Singapore explains how to fix a doorbell in Singapore. It is important to note that their professional house re-wiring, power failure troubleshooting, and lighting installation services need no introduction in Singapore.
Why Your Doorbell Might Not Work
Here in Singapore, the climate can affect your doorbell. Rain, heat, and moisture can cause parts to rust or break. Sometimes, a power surge or even simple wear and tear can be the reason.
Here are some common signs that something is wrong:
- The doorbell doesn’t ring when pressed.
- It rings by itself without anyone at the door.
- It makes a weak or strange sound.
- The button feels stuck or loose.
Knowing what to check helps you fix a damaged doorbell faster.
What Kind of Doorbell Do You Have?
Before we begin, check what type of doorbell you have. In Singapore, most households have either:
- Wired Doorbells – These are built into older flats and some landed homes. They are powered by your home’s electrical system.
- Wireless Doorbells – These are battery-powered and common in newer BTO flats and condos.
What You’ll Need
You don’t need fancy tools. To repair a doorbell, you’ll only need:
- A screwdriver (Phillips or flat-head)
- A new battery (for wireless models)
- Electrical tape
- A multimeter or tester (for wired systems)
- A clean cloth
If you’re missing anything, you can get it easily from shops at IMM, hardware stores in Jalan Besar, or online.
How to Fix a Doorbell
Step 1: Start With the Button
Stand outside and press the button a few times. If nothing happens, try listening carefully. Any soft buzz or click?
- If it’s a wireless doorbell, open the casing. Most have a clip or one screw. Replace the battery and try again. Make sure the button isn’t filled with dust or water. In one case, my neighbour’s doorbell stopped working just because ants had crawled inside the button casing.
- If it’s a wired unit, gently remove the faceplate. Look at the two wires connected to the button. If one wire is loose or corroded, reconnect it securely. A screwdriver is all you need here.
Step 2: Check the Chime Unit Inside
Now head indoors. Find the chime unit, usually it’s mounted near the entrance or corridor.
- Remove the cover (most pop off easily).
- If you’re using a wireless doorbell, check if the speaker inside the chime has batteries. Try replacing them with fresh ones.
- For a wired chime box, check the wire connections. Sometimes, a small tug is enough to see if a wire has come loose. If something feels wobbly, tighten it or tape it back with electrical tape.
Step 3: Test the Power (For Wired Systems)
If both the button and the chime unit look okay, the issue might be with the power supply. Turn off the main circuit breaker first (safety first!). Then:
- Use a tester or multimeter to check if power is running to the transformer (usually located in the DB box or near the doorbell chime).
- If no power is detected, the transformer may be faulty. This part is small but hard to fix on your own. It’s better to call a certified electrician if you reach this step.
Step 4: Replace Parts That Don’t Work
Sometimes, parts are just too old to fix. If the button is rusty, replace it. A wireless doorbell button usually costs $10–$20 in Singapore. Chime units range from $20 to $60.
I replaced my entire wireless system with a TP-Link smart doorbell I bought online for around $45. It was easy to install with adhesive tape, no need for drilling or wiring.
If you live in an HDB flat and don’t want to damage the walls, wireless models are the way to go. They’re also easier to remove if you shift to a new unit.
When to Call a Professional for Fixing a Doorbell
If your doorbell is not working, and you’ve checked the button, chime, and power, it’s time to get help. Don’t risk handling internal wiring on your own. Electricians in Singapore usually charge around $50 to inspect and fix a wired doorbell.
