FAQs
Is it safe to keep trying to start the furnace?
No, repeated tries can build up unburnt gas. Three failed cycles is the limit. Call us instead.
Can I clean the flame sensor myself?
Yes if you're comfortable, fine emery cloth, gentle wipe. But many sensors are within ohm-spec and the issue is something else, so a tech call usually pays off.
