Furnace Blowing Cold Air? Here's What's Wrong — what Monroe homeowners should know

Cold air from a heat-set furnace means the burner isn't firing OR isn't staying lit, but the blower is running anyway. Five common causes — three of which the homeowner can fix.

Most likely causes in Monroe

Thermostat fan set to ON instead of AUTO

The blower runs continuously regardless of whether the burner is firing. Between heat cycles, you feel cool air at the vents. Switch fan to AUTO.

Most common

Furnace in lockout from failed ignition

Tried 2–3 times to ignite, gave up, locked out for 60 minutes. Blower may run; burner is off. See /problems/furnace-not-igniting.

Common

Dirty flame sensor

Burner lights briefly then goes out within 5 seconds. Blower keeps running through the post-purge cycle then shuts off. Repeats next cycle.

Common

Pilot light out (older standing-pilot furnaces only)

Pre-2000 furnaces with a constantly-burning pilot. If the pilot blows out (drafty install, dirty thermocouple), the gas valve closes.

Less common
