Why Is My Thermostat Blank?
A blank thermostat can mean dead batteries, a tripped breaker, a switched-off furnace, or a system safety issue. Replace the batteries if applicable and confirm the furnace breaker and service switch are on. If the display stays blank, call Sterling for professional furnace diagnostics.
Why Is My Furnace Blowing Cold Air?
First, confirm the thermostat is set to HEAT and the fan is set to AUTO. Check the air filter because restricted airflow can cause a furnace to overheat and shut the burners down. If the system continues blowing cool air or shows a diagnostic code, schedule service with a qualified technician.
Why Does My Furnace Light and Then Shut Off?
A furnace that ignites and shuts down after a few seconds may have a dirty flame sensor or another ignition-related fault. Because gas and electrical components are involved, the safest next step is professional diagnosis. Sterling services furnaces throughout Louisville and provides an up-front repair price before work begins.
