🔥❄️ Furnace Fan Running But No Heat? Your System Is Stuck in “Blower Only” Mode ❄️🔥
If you hear the blower running but feel no warm air, your furnace isn’t completing the heating cycle. This happens when the system detects a failure and switches to “fan only” mode to protect itself.
At Uptown Heating & Air Conditioning, we find the cause fast and restore proper heat safely.
⚠️ Why Your Furnace Blower Runs Without Heat
✔️ Broken or weak ignitor
✔️ Dirty flame sensor stopping the burn
✔️ Burners not lighting due to dust buildup
✔️ Faulty control board
✔️ Overheating limit switch shutting off the flame
✔️ Thermostat not sending the heat signal
When the blower runs with no heat, your furnace is telling you something is wrong — and it won’t fix itself.
