Connect the Trane air conditioner to a live power outlet if it isn't operational. Reset or replace the fuse or circuit breaker if needed.
Clear the area around the air conditioner of bushes, leaves, dirt, or debris if the machine seems to be running constantly or not cooling well. Remove the cover from the air conditioner when the unit is in use and ensure that objects are not stacked against the unit. Debris and other material can reduce the air flow and reduce overall productivity.
Clean the filter if the air conditioner is not maintaining an accurate cooling temperature. Turn it off and unplug it, and then open the main access panel. Slide out the filter and clean with a few drops of dish washing liquid and cold water. Rinse well and air dry completely. Restore the filter in the air conditioner with the arrows pointed in the air flow direction.
Use a mild household cleaner to remove grease spots on the air conditioner exterior. Avoid using chemical or solvents to clean the unit, as these can damage the finish.
Completely close the blower door if the air conditioner has power but isn't working. Turn the thermostat to a lower setting and allow time for the air conditioner to function.
