If the cooling isn't working, the homeowner should check the circuit breaker first as it may have been tripped. Resetting the circuit breaker may fix the problem. If not, the next step is to check the thermostat controls. These should be set to the On and Cool settings.
If warm air is coming out of the vents, when the air conditioner is set to cooling, turning off the system for one to three hours may allow it to rest.
If the heat isn't working, Trane recommends checking the gas source first. The gas valve at the gas company's meter should be checked, as should the furnace shut-off valve. If there is no gas coming through, the gas company should be contacted. The next thing that should be checked if gas is flowing is whethert the system is plugged in and turned on. The thermostat should be checked to ensure it is at the proper temperature, and the circuit breaker should be reset. If none of this helps, the homeowner should contact a Trane Comfort Specialist.Learn more about Heating & Cooling
