There is no reset button for the Lennox air conditioner, but you can use the thermostat or pressure switch to reset the system if there is an issue.
Lennox air conditioners are a popular choice because the brand is known for being reliable and having energy-efficient products.
If you have a Lennox air conditioner and it is not as reliable as you have been promised, it may mean that you have to reset your unit’s entire system.
However, there is no reset button on the AC to do this, and you need to follow a set of steps to trigger the pressure switch.
Why are Lennox air conditioners so popular?
Lennox is a well-established brand in the air conditioning and HVAC system market. One of the main reasons that people prefer to buy from Lennox instead of other air conditioning brands is because Lennox products are so energy-efficient.
Frequently running an air conditioning system or an HVAC system can significantly increase your electricity bill, which is why it is important that you choose a unit that is as energy-efficient as possible. Lennox is a popular brand because its products are reliable and cutting-edge.
Where is the reset button on my Lennox air conditioner?
Even though Lennox air conditioners are known for their reliability, there may still be times when your Lennox air conditioner does not function properly or gives you an error message, seemingly out of the blue.
There are many possible reasons why your Lennox air conditioner may need to be reset and the severity of these reasons range from the AC not cooling your rooms effectively, to the unit leaking water or your circuit breaker tripping.
Regardless of the reason why, resetting your air conditioning unit is often one of the first steps to restore proper function and clear any error codes on your air conditioner. Lennox air conditioners do not have a reset button that you can press to reset your unit.
Instead, you have to restart your air conditioner by following steps to switch it off and locate the pressure switch which you can use to restart the entire system before you switch it on again. Moreover, resetting your thermostat can also be helpful to resolve temperature regulation issues.
However, if this does not work and you continue to experience issues with the functionality of your air conditioner, this may be an indication that there is a different problem within the unit itself.
Steps to reset your Lennox air conditioner using the pressure switch
The Lennox air conditioners do not have a physical reset button, but you can use the AC’s pressure switch to reset the system. In order to reset your unit, you need to follow these steps:
- Step 1: Turn off the breaker for your air conditioning unit in order to switch off the unit’s access to power
- Step 2: Remove the back panel of your air conditioning unit.
- Step 3: Find the liquid line (This is a small copper line which runs along the bottom of your air conditioning unit)
- Step 4: Find the pressure switch, which is located somewhere on this line (This is a small, red rubber switch)
- Step 5: Wait 30 seconds, then turn your air conditioner back on
You can also just reset the thermostat of your Lennox air conditioner by switching the unit off, resetting the circuit breaker box, waiting 30 seconds, and then switching the thermostat back on again.
Indications that you need to reset your Lennox air conditioner
The most common reason that air conditioning units need to be reset is that they make an odd sound when you switch them on, but they do not actually switch on or they do, but the room temperature does not cool down to the temperature that you have set for it.
Resetting the entire air conditioning unit can also help you clear any error messages that may prevent you from switching the system on. If any of these problems persist after you have reset the system, it may be an indication that there is another issue elsewhere in the unit.
Other issues that can prevent your Lennox air conditioner from functioning as it should
One of the most common reasons why your Lennox air conditioner may not be working as it should, even after you have reset the system using the pressure switch, is that your air filters are possibly clogged.
Other reasons include dirty condenser coils or an issue with a specific component inside the unit, which means that you may need to contact an HVAC professional for help.
