As the chill of winter sets in across the Francisco Bay Area, the last thing anyone wants is a furnace that refuses to start. Whether you’re in Campbell, Los Gatos, Saratoga, Santa Clara, San Jose, Monte Sereno, Milpitas, Atherton, or Menlo Park, a non-functioning furnace can quickly turn your home into an icebox. But before you panic and call for professional help, there are several troubleshooting steps you can take to potentially resolve the issue on your own.
What to do first when Furnace Won’t Start
First, let’s ensure the basics are covered. Start by checking the thermostat. It might seem obvious, but sometimes the simplest solutions are the most overlooked. Ensure that the thermostat is set to “heat” and the temperature is set higher than the current room temperature. If your thermostat is battery-operated, a dead battery could be the culprit, so replacing it might just do the trick.
Next, inspect the furnace switch. This switch, which often looks like a regular light switch, is usually located near the furnace. It needs to be in the “on” position for the furnace to operate. Accidental switching off happens more often than you’d think, especially in homes with children or pets.
What can I do if the switch of the furnace is not working?
If the switch isn’t the issue, it’s time to check the furnace’s circuit breaker. Locate your home’s main electrical panel and see if the circuit breaker has tripped. If it has, reset it by flipping it off and then on again. A tripped breaker could indicate an underlying issue, so if it happens repeatedly, it might be time to call in a professional.
Another common issue could be related to the furnace’s air filter. A clogged or dirty filter can restrict airflow, causing the furnace to overheat and shut down as a safety precaution. Checking and replacing the air filter regularly ensures optimal performance and can often solve startup issues.
If your furnace is still not working, look at the pilot light or electronic ignition system, depending on your furnace model. For those with a pilot light, ensure it is lit. If it’s out, follow the manufacturer’s instructions to relight it. If your furnace has an electronic ignition system, make sure it’s functioning properly. Faulty ignition systems are a common issue that might require professional attention.
Sometimes, the problem lies with the gas supply. Check that the gas valve to the furnace is open. You should also ensure there are no gas leaks. If you smell gas, turn off the furnace, leave your home immediately, and contact your gas company or a professional technician.
Ventilation issues can also prevent your furnace from starting. Blocked or closed vents and ducts can cause the system to overheat or fail. Ensure all vents are open and unobstructed to allow for proper airflow.
