Steps to Take If Furnace Stops Working
You could have the worst experience if furnace breaks down. Before panicking, it is always advisable to scrutinize the system and know where the problem is. This does not mean fixing the furnace yourself. The furnace is a complicated system and attempting to repair it with no proper experience could cause more issues. What do you do if the system fails? The following are a few things to do if the furnace breaks down. You can then call professionals if these attempts do not fix the issue.
Check Power Supply
A common problem that could cause the furnace to stop working is the power supply. Loss of power could cause the shutdown. It could be an issue with the circuit breaker or the fuse box. Carefully check if the problem could be coming from the fuse box. You need to replace the fuse box if blown. Reset the circuit breaker. If the furnace does not turn on even after correcting power problem, there could be a more serious problem. It might be time to call professionals.
Clogged Air Filters
Sometimes the shut off could be an issue with the system, like clogged filters. If it has been long since you cleaned or changed them, it might be time to. Clogged air filters cause inefficiency with the whole system. In such case, professional furnace and duct cleaning will be necessary to fix it. It is also vital to ensure change the filters frequently.
Check the Thermostat
Another reason furnace could stop working is because of an issue with the thermostat. If thermostat is set below the temperature in the house, the furnace will shut down. Try rectifying the problem by turning the thermostat and see if the furnace comes back on. If on, it means the issue was with the thermostat. However, if it doesn’t, there is another underlying problem. In such a position, it might be advisable to call experts to see where the issue is coming from. They will investigate and fix the problem once and for all.
Check for Leaks
If your furnace uses gas, it is crucial to check for leaks if it stops working. Check if there is a gas leak even before you attempt to repair it. Gas leaks are dangerous and must handled by professionals. If there is a gas leak, begin by opening all doors and windows in the house. It allows proper ventilation. You can also call the gas company to ensure there is someone to repair the leak.
Check the Flame Sensor
Sometimes the issue could be coming from the ignition system. When you turn on the furnace, check how the ignition system works. The system should start to glow. The furnace will try to ignite several times before it shuts down. That means the flame sensor is dirty. The right thing to do is turning off the entire system and cleaning the flame sensor with a clean piece of cloth.
Conclusion
These are several things you should check if furnace has stopped working. However, if none of the above works, it might be best to contact a professional furnace repairer. Do not attempt to DIY any of these serious problems.
