What Does E5 Mean On My Air Conditioner

The e5 on your air conditioner indicates that it has an error with the evaporator temperature sensor. This sensor monitors the temperature of the evaporator coils and tells the air conditioner when to cycle on and off. If the evaporator temperature sensor is not working properly, it can cause the air conditioner to run too long or too short, which can lead to inefficient cooling and higher energy bills.
