A furnace runs continuously almost round the year to provide much-needed heating and ventilation for your homes. As a result, furnace-related issues can become a source of discomfort. In case your furnace stops working, you can attempt these measures to resolve the problem:

1) Changing the Filter

The furnace filter blocks dirt, wastepaper scraps, hair bundles, and other such materials from entering and affecting the system’s internal components. Therefore, a clogged-up filter may be why the furnace is malfunctioning or not working. Changing the filter regularly can prevent such furnace problems.

Changing the filter is a simple process and follows these four steps:

  1. Locating the furnace filter in the system
  2. Deducing the size of the filter
  3. Yanking out the existing filter from the furnace
  4. Plugging in an identical-sized replacement filter

You must turn off the furnace before performing this entire exercise.

2) Inspecting the Thermostat

The thermostat in your furnace regulates the heating level as per your requirement. To detect whether the thermostat is malfunctioning, you can take the following measures:

  1. Initially, check if the main switch for the system is on. Also, ensure that the temperature dial of the thermostat is set to the appropriate degree.
  2. Replace old thermostat batteries with new ones.
  3. With assistance from a companion, check whether changing the thermostat temperature is causing the heating system to work. An audible ‘clicking’ sound in the furnace will signal that the thermostat is functional.

If the thermostat continues to work erratically despite these measures, seek professional help to get it repaired.

3) Monitoring the Furnace Grills and Ducts

Perforated grills cover the vents through which the furnace conducts air circulation throughout the house. On several occasions, the furnace gets overheated due to blocked or dirty vents. You should clean the ventilation grills regularly. Also, you must prevent furniture or other large objects from blocking the vents and causing furnace problems.

Ducts are large pipelines that act as pathways for warm air to circulate the house. Any obstructions along these ducts can cause the furnace to malfunction or cease working. Also, a hole in the duct causes warm air to leak, causing the heating system not to work properly. You can loosely inspect the ducts to locate problems such as holes, blockages, or corrosion along these pathways.

4) Inspecting the Fusebox for Issues

Circuit issues constitute a major chunk of problems in the HVAC system. When your furnace malfunctions, you can open the fuse box for a casual inspection of the electrical circuits. Burnt fuses and circuit breakers commonly cause furnace problems. Here is a handy guide for checking and replacing damaged fuses.
