Lennox AC Not Turning On: Troubleshooting Guide

Not being able to switch on your Lennox AC can be incredibly frustrating, especially during those hot summer months. Fortunately, many of the issues causing Lennox AC units not to turn on can be easily resolved with a few troubleshooting steps. Here, we’ll discuss several common reasons as to why a Lennox AC might not be working, and how to diagnose and fix these problems.

Check the Electrical Circuit

The first step when attempting to troubleshoot a Lennox AC unit that isn’t switching on is to check your home’s electrical circuit. If a circuit breaker has tripped, resetting it could solve the issue. If a fuse needs to be replaced, carefully assess the fuse box and replace any that have blown. Alternatively, if you have access to a voltage meter, you can check the incoming voltage to your AC unit. Most Lennox AC units should have a value of around 240V. If the electrical connection is weaker than this, it could be the reason your AC is not turning on.

Check the Thermostat Settings

The next, and most common issue with a Lennox AC Not Turning On, is that the thermostat settings are incorrect. If the thermostat is set below the current room temperature, the AC will not turn on, as the unit believes that the temperature in the room is already at the desired level. Before you go through any other complicated troubleshooting steps, double check the thermostat settings – particularly the temperature. If your thermostat was accidentally bumped, or your energy-saving mode was activated, this could be the culprit.

Check the AC Disconnect Box

The AC disconnect box is an essential part of your Lennox AC system, as it provides the proper power supply to your AC unit. The disconnect box will be visible on an outside wall near your unit, and you may need to turn off the power before attempting to troubleshoot any issues. Once turned off, you can reset the breakers, inspect for any worn wires, and check for any corroded contacts. As an additional measure, you can use a multimeter to check for any power fluctuations going to the Lennox AC unit.

Check the Condenser Unit

The condenser unit is located outside your home and distributes cooled air on the inside. If the condenser unit isn’t working properly, your Lennox AC could struggle to turn on. To check your AC condenser unit, know that you’ll need to inspect it carefully and thoroughly. Make sure to inspect any refrigerant line and power wires that are connected to the unit. It may be a good idea to clean the condenser coil too, as dust can build-up and reduce the efficiency of the unit.

While troubleshooting a Lennox AC that isn’t switching on can initially seem daunting, these fundamental steps can help you isolate any underlying issues. With these basic troubleshooting steps in mind, you can look for and diagnose any potential problems, and thus, avoid expensive potential repairs. If all else fails, it may be wise to call a reliable and experienced appliance repair company to take a look – especially if you’re not feeling confident in your repairs.
