Furnace Won’t Turn On? Here’s What to Do

Temperatures are gradually dropping, and it won’t be long until you’re turning on your furnace for the first time this season. Most likely, it will switch on without incident, but what if it does not? Are you aware of what to do if your Hagerstown furnace refuses to start? A furnace that refuses to start is a pretty regular occurrence, but luckily, it is often simple to resolve, what to do if your furnace does not fire up properly. It’s frustrating to find that your heating system is refusing to switch on and heat your house. While your first reaction may be to begin troubleshooting settings, many furnace difficulties result from deeper problems inside your HVAC system, and you may have issues with your blower, heat exchanger, heat pump, etc., electrical circuits, or other sensitive components. Fortunately, by learning how to identify issues, you can save time and energy—and determine whether to contact a professional HVAC company in Delaware. Emergency Plumbing, Heating, and Air is dedicated to arming homeowners with the information necessary to maintain a healthy heating and cooling system. Utilize this advice to determine what to do if your furnace won’t turn on, and keep in mind that you can always schedule an appointment with their team of HVAC experts.

What to Do If Your Furnace Refuses to Start?

  1. Conduct a Visual Inspection of Your Circuit Breakers
    Even if you have a gas or propane heater, some components need electricity to operate. If your furnace won’t turn on, the circuit breaker may have been tripped. Verify that all switches for your HVAC system are set to “ON” on your circuit breaker panel.
  2. Ensure That Your Thermostat Is Working Properly
    If your furnace won’t turn on, the thermostat’s programming may have been lost or reset. It may even be set to the incorrect setting. To do a test, set your thermostat about 10 degrees higher than the current temperature and see if the system comes on. Additionally, verify that it is set to “HEAT.”
  3. Examine the Drain Pan
    Drain pans gather water that your HVAC system removes from the air. When the system is operating properly, the excess water should be pumped or drained automatically. If the pan is full of water, a triggered float switch may be preventing your furnace from starting. Whether this is the case, check to see if the drain on the pan is clean or if the pump is operating correctly.
  4. Ensure That Your Air Filter Is Working Properly
    If you’ve been ignoring your air filter, it may be severely blocked, preventing your system from starting.
  5. Conduct a pilot light check
    Many contemporary furnaces will not operate if the pilot light is out. This is a safety measure that prevents natural gas or propane from being pumped into your house.
  6. Examine Your Natural Gas or Petroleum Supply
    Your furnace may be unable to start due to a lack of fuel. The most effective method of determining your fuel supply is to test another gas device in your house, such as your stove. If none of these methods works, call your gas or propane provider.

If you’ve tested everything above and your furnace continues to refuse to come on, or if you smell gas or propane, you’ll need the assistance of the best HVAC companies in Delaware.
