Common Furnace Problems and Solutions

Common Furnace Problems and Solutions

We do not realize the importance of our furnaces until winter arrives. When temperatures drop, your furnace comes to your rescue. It works round the clock to heat spaces in your home. 

Normal wear and tear and regular operation take a toll on the health of your furnace. To help you care for your furnace, we take a look at some common furnace issues and solutions.

Thermostat Does Not Work 

If your thermostat doesn’t turn on, try changing the batteries(if it uses batteries). Clean different parts of your thermostat with a small paintbrush. If this does not work, reboot your thermostat. 

Before you start the rebooting process, make sure the thermostat is set to ‘Heat’. Turn the temperature to about 60 degrees F. Then, turn the breaker switch off for 30 seconds. If the problem persists, consult a furnace repair expert in Fairfield, CA. 

Dirty Filters 

The importance of replacing filters regularly cannot be emphasized enough. HVAC contractors recommend replacing furnace filters every 1-2 months. Unclean filters can cause several problems. Clogged filters restrict airflow, forcing the furnace to work harder. 

If your furnace does not produce enough heat or is constantly cycling off, there is a high probability that your filters are no longer effective and must be replaced. If you put off changing your filters, the performance of your furnace will take a hit. 

Furnace Does Not Ignite

If your furnace clicks as though it is about to turn on, but does not start, it may be having a problem with the ignition sensor. Before you inspect your ignition sensor, check your thermostat and make sure it is receiving power. 

If you suspect that your ignition sensor is having a problem, turn off the gas to your furnace. Remove the front panel and locate the ignitor/ignition sensor (near the burners). Remove and rub it with steel wool to remove residue. Be careful not to damage it. Put the ignitor back in its position and replace the panel. 

Weird Noises

If your blower is making a grinding or scraping noise, your ball bearings may have worn out. Turn off your unit immediately and contact your HVAC expert. 

A shrieking noise may indicate a slipped or worn blower belt. To address this problem, check for visible signs of damage on your belt. Try tightening it. If the belt is too damaged, replace it.
