When winter rolls into Bend, Oregon, the last thing you want is a furnace that won’t kick on. Whether you wake up to a freezing house or notice your system blowing cold air, a malfunctioning furnace can be both frustrating and dangerous during Central Oregon’s chilly months. But before you call in the pros, there are a few simple things you can check yourself that might just save you time and money.
At Einstein Pros Bend, we always encourage safe and proactive steps. Below are the most common issues you can troubleshoot before scheduling professional service.
✅ 1. Check the Thermostat Settings
It sounds obvious, but many furnace issues start at the thermostat.
- Is it set to “Heat”? Make sure it hasn’t been switched to “Cool” or “Off.”
- Is the temperature setting correct? Try turning it up by 5 degrees.
- Is it programmable or smart? Check the schedule—it may be set to turn off or lower at certain times.
Also, make sure your thermostat has working batteries (if it’s battery-powered) and that the display is lit.
🔧 Pro Tip: A blank or flickering display often indicates a power or battery issue—not a furnace failure.
✅ 2. Inspect the Furnace Power Switch
Furnaces often have a dedicated power switch, usually located near or on the unit. It looks like a regular light switch.
- Make sure it hasn’t been accidentally turned off.
- Toggle it off and back on again to reset the unit.
Also, check your electrical panel to ensure the furnace breaker hasn’t tripped.
⚡ Safety Tip: If the breaker trips repeatedly, leave it off and contact a professional—this could indicate a deeper electrical problem.
✅ 3. Change or Inspect Your Air Filter
A clogged or dirty furnace filter is one of the most common causes of furnace malfunction, especially in homes with pets or dusty environments like parts of Central Oregon.
- Pull out the filter and inspect it.
- If it looks gray, dusty, or clogged—replace it.
- Most filters need to be changed every 1 to 3 months, especially in high-use seasons.
A dirty filter restricts airflow, causing the furnace to overheat and shut off for safety. This can mimic a more serious breakdown.

✅ 4. Check the Pilot Light or Ignition
If you have an older gas furnace, it may use a pilot light that can go out. Newer models use electronic ignitions.
- For pilot lights: Follow your furnace’s manual to relight safely. If the flame won’t stay lit, there may be an issue with the thermocouple.
- For electronic ignitions: Listen for clicking or sparking sounds. No sound at all might mean ignition failure.
If you smell gas or feel unsafe at any point—do not attempt to relight. Call your gas provider or Einstein Pros Bend immediately.
✅ 5. Check for Blocked Vents or Ducts
Central heating relies on free airflow. Walk through your home and check that:
- All supply and return vents are open and unblocked.
- Furniture, rugs, or curtains aren’t covering registers.
- No visible damage or leaks in exposed ductwork.
Sometimes a single closed vent can lead to pressure imbalances and make your system shut down prematurely.
✅ 6. Listen for Unusual Noises
Odd noises like banging, clicking, whistling, or rumbling can point to mechanical issues. While you may not be able to fix them yourself, identifying them can help the technician troubleshoot faster.
