Living without a furnace in cold weather can certainly be quite uncomfortable, but your furnace can break down unexpectedly if you do not pay attention to proper maintenance. Irrespective of the type of furnace you have at home, you can do a number of things to ensure that it stays in top condition. Sometimes, you can also handle minor furnace repair tasks on your own, but you should be able to identify the root cause first.
When your furnace stops working, you may have issues with distribution system, heat source, or thermostat. If you notice your furnace not working at all, the problem could be at the source. There may be no power supply to the furnace. It can also happen if fuel fails to reach the unit. The furnace will not work if the fuel is not igniting. Similarly, there may be a problem with the blower if your furnace turns on but you do not get any warm air in the room. It may also be due to a faulty distribution system. Sometimes, the furnace turns on and off repeatedly. If that is the case, the problem may be with your thermostat.
In case you are going to handle furnace repair on your own, you should proceed in a systematic way and ensure the following first. For instance:
- Ensure that the furnace is receiving power. In case of no power supply, the unit is not going to work, no matter what. If there seems to be a problem with power, you may want to check the unit for tripped circuit breakers or blown fuses. You need to check it at the main entrance panel. Keep in mind that some furnaces may have fuses mounted on or in the furnace.
- Consider resetting the furnace before going any further with furnace repair. You may find the button near the motor housing. Reset it and wait for about half an hour. When the motor has cooled completely, simply press the button and wait for the furnace to start. If nothing happens, repeat the same process and wait for another 30 minutes.
- Carefully check the thermostat before performing any repair work on your furnace. The furnace is not going to function properly if the thermostat is not set properly. You may consider raising the setting by 5 degrees to see if it resolves the issue or not.
- Ensure that the gas supply is not blocked. In case your furnace uses oil, you need to ensure that an adequate amount of oil is reaching the furnace.
The fact of the matter is that you can certainly take some steps to resolve common issues related to your furnace. However, it is worth mentioning that you should not handle certain furnace repair tasks on your own. For instance, it is better to call a professional if the circuit trips repeatedly because it indicates a problem with the electrical system and only a pro should fix it for you.
