Why Peoria Furnaces Fail on the First Cold Day

A Peoria furnace can sit unused from March to November. In that time attic heat dries out capacitors, dust coats the flame sensor and mice find the cabinet. So the first cold night of the year brings a wave of calls for furnaces that worked fine last winter. Most furnace repair in Peoria traces back to a handful of parts, and many of them are a single visit.

Symptoms and Their Usual Causes

  • Burners light, then shut off within seconds. A dirty flame sensor that cannot prove the flame.
  • Inducer runs, burners never light. A cracked hot surface igniter or a gas valve problem.
  • Furnace runs in short bursts. It is tripping on the high limit, usually from a clogged filter or blocked return.
  • Blower hums but does not turn. A failed blower capacitor or motor.
  • Nothing happens at all. A thermostat, transformer, fuse or door switch issue.

Quick Checks Before You Call

Confirm the thermostat is on heat with fresh batteries, the furnace power switch is on, the breaker has not tripped and the filter is clean. Then stop. A furnace that keeps locking out is telling you something, and repeated resets can make a small problem bigger.

Gas Safety

If you smell gas, leave the house and call your gas utility from outside. If a carbon monoxide alarm goes off, get everyone out and call 911. On every visit we inspect the burners, the flue and the area around the heat exchanger, and we will not leave a furnace running that we believe is unsafe.

Repair or Replace

Igniters, sensors, capacitors and switches are routine repairs, and they ride on the truck. A failed inducer or control board on a furnace past 20 years old is where we price a replacement alongside the repair. In the older homes of central Peoria, that conversation is more common, and in newer north Peoria homes it is usually a straightforward repair.
