TLDR – No-Heat Triage (Do This First)
Before panicking, check the basics:
1) Thermostat
- Mode: Heat
- Temp: Above room temperature
- Batteries: Replace if low
- Fan: Auto (switch to ON to test blower)
2) Power & Gas
- Furnace switch ON (looks like a light switch)
- Breaker ON (reset once if tripped)
- Gas valve OPEN (handle in line with pipe)
3) Furnace Door & Filter
- Blower door latched (safety switch must engage)
- Replace clogged filter
5) Intake/Exhaust Pipes
These pipes let your furnace breathe. If snow, ice, or leaves block them, the furnace will shut down for safety. Clearing the PVC venting often restores normal operation.
6) Reset the Furnace
Sometimes the control board needs a fresh restart. Turn the furnace power switch OFF for 60 seconds, then turn it back ON to reinitialize the system. This can fix minor shutdown or error-code issues.
7) Gas or CO Alarm?
If a gas smell or carbon monoxide alarm goes off, leave the house immediately—don’t try to troubleshoot. These are life-threatening emergencies. Once outside and safe, call your utility’s emergency line right away.
