When the house is cold and the furnace won't turn on, work through this list before calling. About one in four no-heat calls turns out to be something simple.
Set to "heat," temperature above room temperature, fresh batteries if it uses them.
There's a light switch on or near the furnace. It gets bumped off more often than you'd think.
Reset a tripped breaker once. If it trips again, stop and call.
A packed filter can overheat the furnace and lock it out. Replace it and wait 30 minutes.
The door safety switch prevents the furnace from running if the panel isn't fully seated.
A clogged drain trips a float switch and shuts the furnace down. Clearing the line often restores heat.
If the pilot is out, follow the instructions on the furnace to relight it. If it won't stay lit, the thermocouple has failed.
Ignitors, flame sensors, pressure switches, control boards and gas valves all need a technician. No-heat furnace repair is available 24 hours a day at (855) 459-5498. If you smell gas, leave the house and call your gas company first.
24/7 emergency air conditioning and heating repair anywhere in Maryland. No overtime fees.
