Awareness of how to react when your AC system fails, coupled with rapid action, can greatly ease the discomfort and potential hazards posed by a breakdown during the peak of summer heat.
Check the Thermostat Settings
When your air conditioner stops working during the hot summer months, it can quickly become uncomfortable and even unsafe, especially in extreme temperatures. One of the first checks you should perform involves the thermostat because it is essentially the command center for your cooling system. A malfunctioning or incorrectly set thermostat won’t give the right commands to your air conditioning system.
Start by ensuring that the thermostat is set to “cool” and not “heat” or “off.” This might sound obvious, but simple setting errors can sometimes be overlooked. Next, check that the temperature setting is lower than the current room temperature. This setting instructs the AC unit to start cooling. If your thermostat is programmable, make sure the time and day settings are correct and review any programmed cooling schedules to ensure they fit your current needs.
If the thermostat isn’t functioning correctly, it may not communicate effectively with the air conditioning system. You might find that batteries need replacing if it’s battery-operated. For models connected to your home’s electrical system, ensure that there has been no tripping of circuit breakers that could affect power to the thermostat.
After checking the thermostat, if the air conditioner still does not kick on, or if it is not cooling efficiently, this could be a sign of a deeper issue. It’s possible that the problem lies with the air conditioner itself or another component of the system. In such cases, checking the circuit breaker and ensuring a steady power supply are the next corrective steps. Always consider safety and, if unsure, do not hesitate to contact or consult with a professional HVAC technician.
So, if your AC stops working in mid-summer, start by thoroughly checking and possibly recalibrating your thermostat. This could be a simple and quick fix, saving you time and expense. If issues persist, proceed methodically through other troubleshooting steps, or opt to seek professional help for a comprehensive system check and repair.
### Inspect the Circuit Breaker and Power Supply
Inspecting the circuit breaker and power supply is crucial when troubleshooting air conditioning issues. The circuit breaker is a safety device that automatically cuts off electrical power when the system is overloaded or at risk of damage. When your AC stops working, it is advisable to check the breaker because a tripped breaker is one of the most common reasons for an air conditioning system to cease functioning. If the breaker has tripped, reset it and check if the AC starts working again. However, frequent tripping might indicate more severe problems, such as electrical faults or an overworking AC unit.
The power supply also plays a significant role in the operation of your air conditioner. Ensure that the AC unit is properly plugged into the outlet and that there is no damage to the wires or signs of wear and tear. An interruption in the power supply can prevent the AC from working. Verifying that the power supply is secure and reliable can often resolve simple issues that might cause the AC to stop working.
