🔥 Ignition & Startup Failures

Why Your Gas Furnace Igniter Keeps Failing — Especially in NJ Winters

Gas furnace igniter failure is a top culprit for no-heat calls. In coastal towns like Brick, Toms River, and Long Branch, high humidity accelerates corrosion on ignition components. Add voltage fluctuations during winter storms, and you’ve got a recipe for cracked or fouled igniters.

Signs of imminent failure:

• Furnace clicks multiple times before shutting off
• Burnt smell or visible wear on the igniter
• System short cycles or fails to start on cold mornings

Prevention & Maintenance Checklist:

• Inspect igniter annually (or before heating season)
• Keep furnace area dry and well-ventilated
• Consider surge protection for HVAC circuits

If your gas furnace igniter keeps failing, a professional cleaning or replacement is a must before total system failure.

Furnace Clicks but Won’t Turn On? Here’s What’s Happening

Clicking without ignition usually means the system is stuck in startup mode. The flame sensor may not detect the burner, or the gas valve may be delayed.

What to check:

• Dirty flame sensor
• Gas valve opening delay
• Faulty pressure switch

Pro Tip: Don’t keep cycling power hoping it starts. Schedule a same-day furnace diagnostic and safety check.

Pilot Light Keeps Going Out? Don’t Ignore It

Older heating systems, still common in Monmouth and Ocean counties, use a standing pilot and thermocouple. These units often suffer from:

• Drafts blowing out the flame
• Dirty pilot orifice
• Worn thermocouple failing to signal for gas

Ignoring this issue risks carbon monoxide leaks and total heat loss. Get it checked.

🌬️ Blower & Airflow Problems

How to Tell If Your Furnace Blower Motor Is About to Die

Your blower motor pushes heated air throughout your home. When it begins to fail, symptoms include:

• Humming or buzzing from the unit
• Poor airflow through vents
• Burning smell or tripped breaker
• Unexplained spike in your electric bill

Don’t ignore it—NJ homes with older split systems frequently need blower motor repair or replacement after 10-15 years of service.

Furnace Running but No Air Coming Out?

If your furnace turns on but you feel no airflow, it’s likely:

• A bad capacitor
• Blown control board fuse
• Severely clogged filter

No air? No problem. These are fixable issues with the right diagnostics.

Fix or Replace? The Truth About Blower Motor Repair Costs

In New Jersey, labor rates and older system complexity often tip the scale toward replacement.

Compare Costs:

• Repair: $400–$700
• Full Replacement: $800–$1,500

Rule of Thumb: If your system is over 12 years old and repair exceeds 50% of replacement cost, replacement is more cost-effective.

💧 Water & Condensation Issues

Furnace Leaking Water? What It Really Means

High-efficiency (90%+ AFUE) furnaces produce condensation. If that moisture leaks, it may point to:

• Clogged or cracked condensate line
• Failed condensate pump
• Improper drain slope

Basement moisture + furnace leak = mold risk. Address quickly.

---

Why Your Furnace Drain Keeps Clogging Every Winter

Winter shutdowns from clogged furnace drains are often due to slime or algae buildup in the trap. Fix it with:

• Annual drain flush
• Condensate pan cleaning
• Enrolling in a heater maintenance plan

⚙️ Electrical & Control Failures

The Fuse That Kills Your Heat — A Tiny Part with Big Consequences

Many homeowners don’t realize a blown 3-amp low-voltage fuse can take down the entire heating system. It often blows after:

• Thermostat miswiring
• Power surge during an outage
• Failed transformer

Tip for coastal NJ: Use surge-protected outlets and have backup fuses on hand during storm season.

---

Thermostat Says Heat On, But Furnace Won’t Start?

If your smart thermostat says it’s heating but the furnace stays silent, test:

• G and R wires for voltage
• Low-voltage fuse on control board
• Thermostat compatibility and firmware updates

Common issue: Nest and Ecobee units often fail without proper C-wire installation.

🚔 Noise, Odor & Safety Alerts

Furnace Smells Like Gas or Burning? Read This Before You Panic

Smells from your furnace can indicate:

• Gas leak
• Dust burning off after long inactivity
• Overheating motor or capacitor

Immediate Actions:

• Turn off the gas
• Ventilate the area
• Check CO detectors
• Call for emergency furnace servicing

---

Why Your Furnace Is Making That Rattling or Banging Noise

Loud noises could be:

• Loose access panels
• Cracked heat exchanger
• Delayed gas ignition causing minor explosions

Don’t wait. Noises often signal mechanical wear that can escalate into costly failure.
