If the furnace in your Dallas-Fort Worth home starts acting up, it doesn’t always mean an emergency service call is in order. While some malfunctions and furnace noises indicate serious trouble, the most common furnace problems have simple solutions. Before calling your Dallas heating repair service technicians, try these furnace troubleshooting tips.
- The filter – A clogged HVAC air filter can reduce air output and eventually shut down the furnace altogether. Remove the filter and hold it up to the light. If you can’t see light through the filter, it should be replaced. Carefully replace the filter and turn on the furnace again to see if the simple filter replacement does the trick.
- The thermostat – Reset your thermostat by turning it down a few degrees, then turning it up 5 degrees higher than the original temperature. Wait a few minutes for the furnace to re-engage and light.
- The power supply – Look for the furnace’s power switch, usually found beside or inside the furnace cabinet. It should be set to “on.” Also check for a tripped circuit breaker or blown fuse.
- The fuel supply – The gas valve should be open, with the handle in line with the gas pipe. With an oil or propane furnace, check that your tank isn’t out of fuel.
- The ignition – If the furnace in your Dallas-Fort Worth home has a pilot light, make sure it’s lit. If your furnace uses an electronic ignition, which is the case with newer models, reset the ignition controller by turning the furnace power switch off and back on or by lowering, then raising the thermostat. Then listen for the spark or watch the hot surface igniter for a yellow-orange glow.
- The exhaust pipe – Inspect the outdoor exhaust pipe for any snow, leaves or debris that may be blocking the airflow.
- The motor – An overloaded blower motor will stop working until reset. Near the motor’s housing you’ll find a reset button. If nothing happens when you press it, wait half an hour for the motor to cool and try again.
