Furnace not starting: 6 common causes
Common reasons a furnace will not start in Montreal and Laval, and what to check before calling. Free estimate, RBQ-licensed technicians. ☎ (450) 328-1110
A furnace that refuses to start in cold weather is stressful. Before calling, a few simple checks sometimes solve it.
Check these yourself
Is the thermostat set to "heat" and above room temperature? Is the breaker on? Is the filter clean? Is the furnace switch (usually nearby) in the on position? Is the access panel fully closed?
Causes that need a technician
Faulty ignition or pilot, a dirty flame sensor, a failed blower motor, a bad control board or a gas supply issue. These repairs require a certified professional.
