Every installed system requires monitoring, maintenance and repair where necessary to ensure its smooth functioning. Without proper maintenance and timely repairs, a system may become injurious, collapse or underperform which becomes costly.
Air condition repairs should be done as a Do It Yourself (DIY) or you may have to engage the services of a skilled person. Such a person will do the scheduled routine inspection of the whole unit and recommend the required repairs.
How to Check Functionality of Your AC
The following steps can help you perform air condition repairs for the given issues:
1. The Central Air Conditioner does not automatically turn on
* The central air conditioning is usually set to 240 voltage. Check the main switch or secondary one for a circuit breaker that could have tripped or a fuse that may have blown. Turn off the circuit breaker then set the circuit breaker or fix the fuse then turn the power on again incase this is where the problem was.
Why You Should Call for a Professional
Should the problem persist, then the possible cause could be a short within the system. You may have to seek the services of a professional to track the short and fix it.
* Check to ensure your thermostat is set to “cool” with its temperature set 3 degrees lower than the ambience temperature of the room
* Check to ascertain that the power is switched on and ensure the compressor’s 240 voltage is still flowing.
* Disconnect power to the air conditioner by switching it off. Unplug the thermostat cover from its casing.
* In case it uses batteries, change them and fasten the wire to the terminals properly then cover the thermostat carefully making sure you do not upset the wire connection. Wait for some 3 to 4 minutes and re-test the system.
* If that fails to start it off automatically, then uncover the thermostat and detach the Y terminal wire. Switch on the power again and use the insulator to hold the bare Y terminal on to the R terminal for approximately 2 minutes. If the compressor starts running then the issue lies in a faulty thermostat and needs replacement.
How to Replace a Thermostat
* Switch off the power and detach any screws and remove the thermostat’s cover
* Label each wire according to the terminal it connects and disconnect them. Curve the wires a little so that they are not pulled back behind the base.
* Unfasten the thermostat’s base from the wall while ensuring you clip the wires to weigh them down so they don’t pull backwards into the hole in the wall.
* Strip off a bit of the casing to expose half an inch of wire and use a metal cleaner to rub the ends.
* Detach the new thermostat’s base from its cover and unclip the weight holding down the wires. Attach the wires through the base openings till they emerge under the terminal board and clip them to hold them in place.
* Screw the thermostat base into position. You can use paper towels to prevent drafts.
* Connect the wires according to the manual instructions making sure they do not touch.
* You can install batteries if need be
* Switch on the power and follow the manufacturer’s instructions to set-up the new electronic thermostat.
