Whenever your AC unit fails during the hot seasons, you may be forced to wait for days before a technician can come to your home to service the unit. If you are not willing to wait for that long, you can always take matters into your own hands. LS Handyman Singapore explains how to do it:
1. Switch Off the Power
Go to your electrical box and gently unplug the disconnect block. Use a voltage sniffer to confirm that the power is truly off.
2. Clean Your Condenser Coils
You will need to use the garden nozzle to remove any debris that may have built up inside the lid. Make sure that you use the nozzle to reach all the hard-to-reach areas such as the fins. Once done, adjust the stream so that you can use it to flush any dirt and debris present in the coils.
3. Examine the Fuses
Grab the multi-meter and confirm that it has been set to the lowest Ohms scale possible. Touch the black and red leads that are on each fuse. A numerical reading shows the fuse is ok, while a zero reading shows something is wrong.
4. Discharge the Capacitor
You will need to remove the capacitor from its retaining brackets. Use a screwdriver that is not insulated to touch the various terminals. Note down the readings.
5. Installing a New Capacitor
Take your new capacitor and place it inside the brackets. You will then need to tighten it using the available screws. Ensure the wires are properly secured using a zip tie.
6. Exchange the Contactor
Unplug the contactor from the old location and place it in the new location. Ensure the connectors are properly tightened. Make sure that the contactor has been properly secured in its condenser.
7. Swap Your Fan Motor
You should start by marking the blade to be able to note which side should be up and vice versa. Gently loosen the screws before removing it from its shaft. You will then need to install the new motor. Confirm that it is properly routed before securing it with a zip tie.
