How do I Reset my Lennox Air Conditioner

The process of resetting your Lennox air conditioner may appear complicated at first, but we’ll explain it in simple terms.

Lennox is a well-known brand in the market for air conditioners and other HVAC systems. One of the main reasons why people prefer to buy air conditioners from Lennox instead of other brands is that Lennox models offer the energy-efficient unit.

Why would you want to reset your Lennox air conditioner? There are a few reasons, but a tripped breaker is the main one.

An air conditioner has its own circuit breaker, just like most other electrical appliances. It is a safety switch that protects your unit by turning it off right away if it detects an overload.

Does Lennox AC have a reset button?

The Lennox air conditioner does not have a reset button. However, the system can be restarted through a thermostat and/or a pressure switch.

How to reset Lennox air conditioner?

The easy way to reset Lennox air conditioner is from the circuit breaker. To reset your Lennox air conditioner, turn off your unit but leave it plugged into an electrical outlet. Go to the box where the circuit breakers are and find the one that connects to your unit. Turn off the circuit breaker, then wait 30 seconds before turning the switch back to where it was.

Another way is to reset your Lennox HVAC system is from the pressure switch.

  1. First, shut off the circuit breaker that controls the air conditioner’s power before doing anything else.
  2. Next, you’ll need to take off the unit’s back panel.
  3. Find the liquid line (the copper line) at the bottom of the unit. When you find the line for the liquid, you’ll see a red rubber push switch.
  4. You can reset your Lennox AC by pressing that switch.

If the above steps don’t work and you see a yellow light continues flashing, there’s something wrong with your Lennox air conditioner.

Always remember, regular maintenance is the best way to keep your Lennox air conditioners in good shape.
