When your furnace suddenly shuts down, we know how stressful and uncomfortable it can feel—especially during an Indiana winter. If you ever find yourself searching for heating repair in Fort Wayne, you’re already taking the right first step toward restoring your comfort. At Collier’s Comfort, we’re here to walk you through what to do next.
1. Check the Basics First
Before assuming the worst, start with a few simple checks. These quick steps can save you time, stress, and even the cost of an unnecessary service call.
Make sure your thermostat is set correctly
Switch it to heat, raise the temperature a few degrees, and ensure the display is working. Sometimes a low thermostat battery is all it takes to shut everything down.
Inspect your furnace switch
Your furnace has its own power switch that resembles a light switch. If it was bumped or turned off accidentally, the furnace won’t run. Flip it back to on and listen for activity.
Look for a tripped breaker
Your furnace relies on electricity—even gas furnaces. If the breaker tripped, reset it. If it trips again immediately, that’s a sign you need a professional.
2. Check Your Air Filter
A clogged or overly dirty air filter is one of the most common reasons a furnace stops working. If airflow is restricted, your system may overheat and shut down as a safety measure.
Remove the old filter, hold it up to a light, and replace it if you can’t see through it. Restart your system after installing a clean filter.
3. Examine the Vents and Registers
Blocked vents can cause temperature issues that force your furnace to work harder—or shut off altogether. Make sure furniture, rugs, or décor are not covering your vents. Opening all registers, even in unused rooms, helps your system operate smoothly and safely.
4. Inspect the Pilot Light or Ignition System
If you have an older furnace with a pilot light, make sure it’s still lit. If it’s out, follow the manufacturer’s instructions to relight it—only if this is recommended in the user manual. For furnaces with manual pilot lights, we still recommend hiring a professional to have the pilot light inspected.
And for newer systems with electronic ignition, a failure could mean a faulty igniter, sensor issue, or control board problem. These components require professional handling.
5. Emergency Troubleshooting for No-Heat Situations
If your furnace still won’t run and the temperature is dropping quickly, here are a few additional steps you can take:
- Check for unusual smells or noises. If you detect burning, gas odors, bangs, or grinding, shut the system off immediately.
- Avoid using space heaters improperly. Keep them away from fabrics and never leave them unattended.
- Keep doors closed to retain heat. This can help maintain temperatures until help arrives.
And remember—you’re never stuck waiting when you call us.
