Straight talk for Griffith homeowners

We’ll keep this plain. If your furnace in Griffith stopped working, the odds are good that one part failed. Not the whole furnace. One part. Our job is to find that part, tell you what it costs to fix, write the number down, and let you decide. No commission, no sales pitch.

Griffith grew up as a railroad town, and a lot of its houses are modest brick and frame homes that have been kept up for decades. Many of them are on their second or third furnace, sometimes with ductwork older than the owners. We work in those basements all winter.

That blinking light on the control board

Take the lower door off most gas furnaces and you’ll see a small circuit board with an LED. When something goes wrong, that light blinks a pattern. The key is usually printed on a sticker inside the door. Two blinks might mean a pressure switch problem. Three might mean the limit tripped. It varies by maker.

It’s worth writing down the pattern before you call. It helps. But the code only points to where the furnace noticed the trouble, not always the cause. A pressure switch code might mean a bad switch, a blocked vent, a clogged drain, or a weak inducer motor. That’s why we test instead of swapping the part the code names.

When the board itself is the problem

Sometimes the control board really is the failed part. A relay burns out, a fuse blows, or the board just stops sending the signal to light the burners. You might get a furnace that’s completely silent, or a blower that runs nonstop and never shuts off.

A control board is one of the more expensive common repairs, and it’s still a repair, typically in the hundreds, not thousands. We also look for what took it out. A shorted thermostat wire or a failing motor can kill a new board just as fast, so we check before we install one.

Price on paper before we start

A real person answers when you call, day or night. You hear the diagnostic fee before a tech comes out. Once we know what’s wrong, the repair price goes on paper. You approve it first, and the bill matches.

“It’s old” isn’t a reason

An older furnace in an older Griffith house can still have plenty of good years in it. “15 years old” is not a diagnosis. We check the heat exchanger, burners, venting and safeties. If those are sound, fixing the failed part is the sensible move. If a repair would cost more than the furnace has left, you’ll see both prices on one sheet. Our guide on how long a furnace lasts in Northwest Indiana gives you some context.

A few other Griffith calls

Not every no-heat call is a board. We also see thermostats that lost their wiring connection, igniters that cracked after years of heating and cooling, inducer motors with worn bearings, and gas valves that stick. Some of those set a code and some don’t. The approach is the same every time: test, find the failed part, show it to you, and write the price down. If the fix is a loose wire at the thermostat, that’s what you pay for.

Before you call

  • Thermostat on HEAT, set above room temperature, batteries fresh
  • Furnace power switch on, breaker not tripped
  • Filter not packed with dust
  • Blink pattern written down, if there is one

If you smell gas, leave the house and call NIPSCO or 911 from outside. If a carbon monoxide alarm sounds, get everyone out and call 911.

Questions about furnace repair

What does the blinking light on my furnace mean?

Most furnaces flash a code on the control board to say what went wrong: an ignition failure, a pressure switch problem, a limit trip. The key is usually on the inside of the furnace door. We read it too, then test the parts behind it, because the code points to a symptom, not always the cause.

Is a control board replacement expensive?

It's one of the pricier common repairs, but it's still a repair. It's usually a few hundred dollars, not thousands. We also check why the board failed, like a shorted part or a wiring issue, so the new one doesn't go the same way.

Why is my furnace completely silent?

Start with the basics: the thermostat, its batteries, the furnace power switch, and the breaker. If all of those check out, it could be a blown fuse on the board, a failed transformer, or the board itself. Call us before you start swapping parts.

Do you push replacements?

No. Our techs aren't on commission. We quote the repair first, and replacement only comes up when the math says so. You see both numbers and decide.
