Equipment (continued)
The fan is On, but no hot air is coming from registers.
• Check that the system setting is set to HEAT. Press the SYSTEM button until the
HEAT icon is displayed.
• Verify that the air handler breaker is not tripped and that the thermostat indicates the
system is On (STG 1 displayed).
• If a fossil fuel (oil/gas) furnace, check the furnace burner for visible flame. If no flame
or pilot, call your heating and cooling contractor.
• If a heat pump, verify that the outdoor compressor and fan are running. If the
compressor is running and warm air is still not being detected from the system, the
refrigerant level may be low. Call your heating and cooling contractor.
