To diagnose problems in a Trane rooftop air conditioner, first check whether the air it is blowing is cool. Then check whether the thermostat is set correctly. Once you have done this, check whether the machine is getting gas and electricity. Finally, check the filters and vents for big blockages.Continue Reading
If the air coming from a Trane air conditioning unit is not cool when it is supposed to be, turn off the air conditioner for up to three hours. This resets the thermostat, allowing the unit to function correctly again.
If the thermostat is not set correctly, the air conditioner will not function the way you want it to. Make sure to double check the thermostat that it is set to Cool and not Heat, and that the desired setting is lower than the ambient temperature.
If there is no gas flow to the unit, it will not heat the air it blows through the ducts. Make sure the gas lines are functioning correctly by examining the lines. Additionally, check that the unit is receiving power by checking the relevant lines and breaker switches, as the unit will not function at all without power.
As the Trane rooftop unit uses ductwork in order to distribute air, it is susceptible to blockages. Check the ducts and filters for anything that could be interrupting the airflow to any of the rooms. Check the ducts starting from rooms that are not getting enough air flow and work your way inward to the air conditioner.Learn more about Heating & Cooling
