It could be possible that you have experienced your furnace burner conking out on you just when you planned to take that long overdue day off work. For safety purpose, you should work on that furnace as soon as possible. Here are some things that you can check to make your furnace churn out that much needed heat.
1. Electrical Connections
If your furnace burner is powered by electricity, check the electrical connections such as the plug and the power cord. Make sure that it is unplugged from the socket before even attempting to do this. Look for any cracks or cuts on the cord that may be causing the erratic behavior of the furnace. Also check your circuit breaker since you might have a blown or faulty fuse.
It is recommended that you go check the thermostat and make sure that it set correctly and that it is on the “heater” option. Turn it up a little more than it is presently. You have to make sure that the setting is set higher than the current temperature of the room. This should then bring your furnace burner to life.
3. Pilot Light
Check the pilot light if it is lit or if it has enough capacity to even power your furnace. Remember that the heat will originate from this and if it is not sufficient, your furnace may indeed experience problems and may not work to its full potential. If it is out completely, you have to light it back on.
Check the gas as well, since this is where the pilot light gets its fuel. Bend down near the location of the gas lining and try to check if you smell a faint scent of gas. If you can smell something, or hear something leaking, try to check the contact points and try to secure them. If the gas lines are still faulty or leaking, you may need to have them changed immediately by the manufacturer or get a professional to repair them. This could be a safety hazard so attend to this quickly.
In some cases, the filter could be dirty and has already clogged up everything, meaning it isn’t able to do its job correctly. Remember that the filter is supposed to clean the cold air that goes into the furnace burner. A dirty filter means there is a possibility that it might be sending the wrong signals to the other parts of the furnace such as temperature and airflow, causing it to turn on and off erratically. A filter should be replaced every so often in order for the furnace to be working at optimum level.
6. System Error
It could be a system error so try and hit the reset button. The whole system may just need a restart in order to get all its bearings straight. Similar to a computer or even a human brain, if your furnace burner has been working non-stop and has been abused day-in and day-out, a simple flick of a switch may be able to do it.
