In this article, we will discuss how to reset an AC unit DIY way, without having to call an HVAC technician. In peak summer months when the sun is over your head, the last thing you would expect is an air conditioner malfunction. If it is a minor problem or glitch, you can fix it yourself. Resetting an air conditioning unit is a method to restore Status Quo, and bring back the AC into normal running mode. Let’s get an insight on the ways of resetting an HVAC unit.
Learn How to Reset an Air Conditioner?
Using the Reset Button
It is a small red button usually located in and around the heating/cooling unit that can help rectify minor issues. Such problems are common in home electrical appliances that are prone to mechanical malfunctions. Your AC can disconnect after a sudden power outage. This button with a ‘Reset’ label can help solve the problem.
Press the reset button for around 3-5 seconds, and check whether the compressor and AC fan kicks off immediately. You would hear three beep sounds before it starts to reboot. Before resetting the HVAC system, ensure there is an adequate supply of power. The Reset button is usually located in the outdoor unit.
Reset Using the Isolator Switch
If your AC does not have a Reset button, or is not responding when an AC reset is performed, you can reboot it with the isolator switch. The function of an isolator is to disconnect the power after a sudden surge in electrical current. The isolator switch is located beside the outdoor unit and looks like an ordinary electric switch with a knob.
Switch off the knob for 30-45 minutes, and let the components in the AC to reset. After the stipulated time frame, switch on the isolation switch, and restart the AC unit. The isolator protects the air conditioner from electrical discharges, but it is different from a circuit breaker that disconnects the power supply when there’s a surge.
Resetting the Circuit Breaker
If you’re unable to reset an AC unit using the reset button or isolator switch, you can try using the circuit breaker. It is usually located outside the house, or just near the entrance. This box comprises one main switch and other smaller switches for different circuits in a residence.
Whenever there’s a power outage or electrical surge/spike, the circuit breaker switches off. This helps prevent electrical accidents, resulting in fire. Once you’ve located the circuit breaker box, find the switch in a neutral position, and turn it on. Then restart the AC for normal functioning.
Resetting an AC from the Thermostat
If all such troubleshooting doesn’t work, reset an air conditioner, by resetting the thermostat. The thermostat provides signals to your HVAC unit to cool a space accordingly by reading the temperature.
If there are defective components in your AC, the unit or system may not cool at all. You can check the batteries and replace them, before restarting your AC. Or else, you need to call an expert in air conditioning repair services in Dallas, TX.
Reset Using the Switchboard
When all proven tactics fail, a reset via the switchboard is the last resort or option. Find the switch or circuit breaker dedicated to your AC, and turn it off. Leave it for half an hour, and then switch it on. If the switchboard only has fuses, take out the right fuse for the AC. After 30-45 minutes, put the fuse back into its original position. Start your AC unit to check whether the unit is cooling properly.
Reset Using the Powerpoint
This is the bread-n-butter method employed by all. Simply find the electrical panel close to the air conditioner, and shut off the power. Unplug the power cord, and disconnect the supply of power. Leave it for 30-45 minutes and plug back the cord. Once the power supply is restored, switch on the air conditioning unit. This is how to reset an AC unit in a DIY manner.
