Resetting your Lennox air conditioner may be necessary for various reasons, such as unusual noise, water leakage, or failure to turn on. This article explores the reasons for resetting and provides a step-by-step guide on how to do it.
Lennox Air Conditioner Reset Procedure:
A home air conditioner functions by extracting warm air from the space, cooling it, and circulating it back into the room until the desired temperature is reached. Like any other device, Lennox air conditioners may require a reset for various reasons. Some scenarios where a reset might be necessary include:
1. Unusual noise without effective cooling.
2. Hardware issues leading to water leakage.
3. Unused air conditioning for an extended period.
4. The need to turn on the air conditioner after it has been turned off at the thermostat.
5. Unexplained failure to turn on the Lennox air conditioner.
Resetting the Lennox air conditioner can be beneficial in addressing errors or malfunctions. To perform the reset:
1. Turn off the thermostat’s AC unit.
2. Switch off the breaker for at least 30 seconds before restarting.
3. After turning on the breaker, use the thermostat to exit the reset mode.
If issues persist, it is advisable to seek assistance from an HVAC professional.
Locating the Lennox Air Conditioner’s Reset Button:
Contrary to some air conditioners, Lennox units do not have a specific “reset switch.” However, a pressure switch can be reset to restart the system. Follow these steps:
1. Turn off the breaker connected to the Lennox air conditioning system to cut off power.
2. Remove the backboard for better access.
3. Look for the liquid line at the bottom of the unit. If a red rubber push switch is present, press it to reset the pressure switch.
If the problem persists and a yellow light is flashing intermittently, there might be another issue that requires attention.
